Peck Drill
« on: February 16, 2009, 09:23:16 PM »
Evening/Morning Everyone..

I figure I should start to chronicle this build, as its taking longer.. and is more involved.. and actually might be useful to others LOL.

The basis of the drill im making if from Ralphs peck drill he made, for doing tiny holes in things.
Mine is a bit larger, so I took his design, and used what I had available.. and sized things for my needs.. (I think)

I have some cad drawings I drew up basing things on Ralphs design.. but I have deviated a bit already.. so they are not really relevant anymore. LOL
Look at Ralphs video to see how its done correctly  :headbang:

In essence.. its based on a 1..75" diameter piece of Stainless.. with a steel shaft that is .65" that slides inside, and will ahve a handle the same as Ralphs did coming out the top.

Body of the peck drill


Facing it


Boring the Hole after Milling the slot (Video CLip to follow)



Turning the .75 Shaft down to .64. What a bear to get that damn thing true.. WOW. Now I know why they grind shafts.




Getting ready to round the shaft end.. (Yes John.. I DO get some little swirl marks from the cap screws.. I took this pic for you.. cause you had asked.  :thumbup: )


Video clip to follow.. will try to condense it some so its not forever long.

Great Job Scot  :thumbup:

You get a great buzz when you use a home made tool to make more tools, as they say tools make tools. :whip:

Enjoyed the video  :clap: I'll have to get to grips with that skill. I think I'll nominate yours for a Mad Modder Oscar. :ddb:

Have fun

Nice!  Glad the drawings were of some use!..... It looks like your getting there pretty quickly to me  :dremel:



Stainless too!!! You like to have fun then!  :bugeye: 

I never took video of my build, just a few photo's (I wasn't on any forums when I built it  :(.....  :)  )



So Stew.... This guys  :ddb:  name is officially  M.M.Oscar then? Sounds like a rapper!!!    :lol:   Still..... Think it might stick!?



Looking forward to seeing the rest Scott  :thumbup:

Very nice SPiN. I see you've got maching down pretty good. :thumbup:

By the way I've got lite I'll sell ya'. :D

Hey Bog's, great idea. Instead of Karma's we'll hand out "Nana's". 1 to 5, 5 being the best, or should the number go higher?  :D

No Bernd,

Methinks the 'karma' idea would be a bad move.

Competition like that can easily cause bad feeling. Especially where a newbie works his guts out, makes a few mistakes and gets no recognition, when someone with years of experience, creates masterpieces every week, and the whole population thinks the sun shines out of you know where, and gets so much karma, he thinks he can walk on water.

 :ddb: :ddb: :ddb:

It was my mistake, I should have just said 'GREAT JOB'.

Bah.  It doesn't matter a bit.  Look at HMEM: you'll see I have 4 karma, and some of the guys over there doing superb work have one or none. 

Anyone that takes stuff like that seriously probably isn't the type to enjoy the banter here anyway.

Thanks so much guys

And no I am not letting any of this type of thing go to my head, nor have my feelings hurt! I learned long long ago, there is always someone better, richer, smarter, etc etc. So get over it and do your best. Its all you can do. I think I have decades of hands on work to hold a candle to things I see here LOL.
Then again.. my friends at the race shop.. nothing they make on the tools looks anything like what we do here.. But it does its job on the race cars really well. /shrug

But I do have to say, I have been showing them some of the things I have done, and or am doing.. and I see the gears churning upstairs...  :clap: I think step 2 is to get the one owner onto the site.  :mmr:

I see so much of your work, and have to show my wife, and or boys, and I am genuinely impressed. And its not the bling.. its not the shiny finished product.. just seeing the mechanisms work.. thats the thing to me. All the different ways of going about things.

The file maker for example!! I never thought of how they are made.. but.. the entire thing has my mind reeling.. from the hammer, to the chisel, to the way he does it. Mind boggling.

I figure I will put things up here so that it may help someone else out like you all have me. I read all these posts, and see the snippets of projects.. and it really helps me take a look at things. Gives me a lot of options on how to do things, and or how to do things more efficiently, or less efficiently.. but more accurately.

Its Tuesday.. working working working. More updates this weekend!!  (I might have to go visit the Holy Grail and make my handle from stainless instead of the mild steel I was gonna use... and I might actually need to get a bit of brass for a ball on the end :P

Looking good! So now I am going to sound daft... what's it going to do? I realize peck drilling, but how is it going to work? Anxiously awaiting the results of this one. Nice machining so far.

On a OT side note... Karma will never be here. I don't like it. No reason for it. Everyone here knows they are important (if they don't, they should). This place is not a popularity contest... there is enough cr@p we deal with in real life, don't need it here.

He he he

Remember the really Odd 5/8-16 Tap I had to get?? Well thats for the MT-2 Arbor I have to mount the larger portion in the tailstock.
The shaft that slides into the hole will be machined to have a shaft connect to it and stick up out of the milled slot.
On the end of the shaft (It will be cut down) I will cut a Taper in it to mount a Drill Chuck.
Make a pivot for the shaft sticking up out of the milled slot.. and voila... you slap it in the tailstock and then move the arm to extend the drill chuck towards your work.

Dont have CoC installed on this PC so I found a different freeware version....

HA HA HA HA HA

Well I have been working now.. for (looks at clock) 26 Hours with a break for 6 hours for sleep. (I worked late on a conversion to new software project)
After another 8 or 9 hours this work week will be done. (Monday was a Holiday)

THEN I can start on the project once again... (Of course.. this is after I hopefully pick up my new tool Thursday..  :ddb: (And yes there will be some pics) )


And I dunno.. it might be only the shows I watch.. well. Ok it prolly is.  I always hear the Brits on the TV shows I see refer to the Americans as basically.. Fat Cowboys. Sorta the stereotype. Not just in the traditional sense.. but more of the lifestyle, and mannerisms. And I have to agree.. a LOT of Americans are that way. Not bashing... just... /shrug How it is.
Its like describing how Americans have bastardised the English language into a muddle.
Brits dont pronounce Vowels..  cour=Car (crusty snooty British accent Im picturing)
Auzzies Over emphasise vowels.   cAh= Car (Cocky Auzzie Accent)
Americans.. well we wouldnt call it a car. It would be a ride, dub, hooptie, sled, jalopie, "name of the car", "brand of the car". and just about anything BUT calling it a car.
BUT... when we do say it.. it would be more like KaR=car

Watch some older Top gear.. I get a kick out of the trip to America.. when they went to Miami to buy used cars. I wouldnt have gone into more than HALF the neighborhoods they went into.
Jeremy makes fun of us Americans wanting cheese on everything.

Just thought I would point out Spin.

One of your holes will require to be a slot, otherwise you will get a mechanical lock. That is because the bottom pin hole in the lever is in fact swinging thru an arc, if the top pin in the operating handle is fixed.

Have a look at the genuine C-o-C sketch below, nothing like your pirated Crap-o-Line piccy.

Update time!

Ok sooo I worked on the handle tonight.. Only had a couple hours to play.

I tapped the top of the handle in 1/2-20... why? just because.. no real reason on that thread, other than it was a finer thread than the others in the generic tap set I had.


So here we go..

Turned the .625 hex bar down some so I could tap it.
But as its a bit larger diameter.. and the tap was taking some.. torque on it.. the cheap cast holder... well..... you can see the result.
Guess I need to get my ass in gear on the Die Holder project.... BUt I will need the peck drill for the die holder.. LOL.



Judicious use of a 1" wrench.. and all was better.


Not so bad... I think.


Rounding the hex bar.


Ball turner with the cutter reversed.. and kicked way out.. I didnt measure it.. but its way out there. I am thinking its a good 2.25 inches from center, if not 2.5 inches.
The end result is a very smooth curved cut that is very gentle.
BTW.. the cutter holder I made.. REALLY came in handy with the extended legs on it.. as I was able to move it way out and still have all 4 screws lock it in place securely.
I have video of it in use.. but need to compile a clip from the activities. (its late just posting for now)


End result of the 4 Cuts...



Complete handle cuts.. minus the ball (need to buy some brass) and minus the cuts for the slot




A interesting problem.. I had to tackle.. and didnt know how to.. so I guessed.. and it didnt work as good as I would like.. so I will need to learn a better method for this.
The round bar.. has a slot cut.
I had to cut it deeper.. and needed to re-mount it in the vice.
SO I put it on the parallels.. got it to the right height.
Then I put a round bar in the mill.. and lowered it into the slot.. and then ran the cross slide till the part was touching the rod. Then rotated it till it was flush.. and snugged the vice.. then re-checked.. and locked it down.
As it turns out it was off in the bottom by 1/16 or so of an inch. AKA the bar stock was rotated slightly.
Suggestions on how to do that would be greatly appreciated.... it exceeds my machining experience.







Tomorrow after getting the brass for the knob, a block of metal to make tool holders for the QCTP, and a bar to queue up for some die holders.  and the new tool.. and hopefully a dovetail mill...  :proj:
I will try to get in there and get more done.

See generic American COC to follow...

Ok here is the idea for the re-located pivot.

Adds some work.. but allows some more strength in the assembly. And also will allow some additional stroke to make sure I utilise the entire range of the slot.. (yes I already calculated the pivot points and the stroke for the thing.. and it will go max length... Anyhow... Input always welcome.

If its overkill.. lemme know! LOL

Now that's what ball turning the tool is real good at..... very pleasing curves...... in your handle Scott   :thumbup: 

Just from the scale of that in your hand I can see this is going to be a monster of a peck drill!!!! (either that or you have tiny hands!!??  :lol:)

Interesting place to store your chuck key too!!  :bugeye:   (I know, it was a handle for the job at hand  :thumbup:)


So where's this chunk of brass??  :)

Well it's a long and drawn out process Ron.... Are you sure you want to go ahead with it?? 

Firstly you have to ask me nicely.

Secondly you have to supply me with your e-mail address.

Thirdly you have to open your mail!!   :)



The only two thigs I ever ask are :

1/  Please show me the pic's of what you make.

2/ If anyone wants the drawings from you that you ask them to ask me directly. (I don't often bite.... and rarely refuse to help  :) )


Not too much to ask is it??

Woo long day.

Didnt have a chance to work on things.. BUt I did go to the Holy Grail.

FIRST!!!!

A LoC  :worthless:


Thats what Im thinking of.. Im actually re-doing the real auto cad to do the math on the throw.. to make sure it will go far enough etc.

Picked up the chunk of Brass for the handle. Thing is.. they didnt have 1.5" diameter. Soo I had to get brand new brass. 6.15 a pound.
I also went to the tool place.. got a 0-1/2" drill chuck for the peck drill.
AND...HSS Dovetail cutter 60 degree, 1-3/8 diameter. SO that will go with the bar of 1"x3" by 24" long steel I bought.. so I can make more tool holders for the lathe  :proj:

ANNNNND
THe Unobtainium 5/8-16 Taps arrived!!!!  wooohooo


SO now I THINK I have all the parts to make this thing work. Now I just need to assemble it.

Pics to follow!!!!  (And yes.. will update on the whole.. concept of the mount thing.. if I think I need it. Space wise.

OK I gae it some time in Autocad..

Looks like I dont need to make the pivot out the top of it.

Here is a drawing I made.
It shows the handle with its slot cut in it. From the centerline of the shaft, downward.
With a .25 drop from the top of the larger body, and a .25 shaft, it will rotate and give me 1.4 inches of drill travel. SInce its a pecker.. it should be more than fine.

Anyhow here is the cad clip. (the rings are the travel arcs btw.. this is a side view.)

TIME for an update!!

I have a slew of pics I put up on Imageshack.. so I will put them in. THings that happened over the busy weekend, and I just now have a chance to make a post with the detail LOL.. Or some of it.


OKEY Here we go!

(Yes Lots of Pictures)  :worthless:

Chunk O Brass, freshly purchased from the Holy Grail... and since it wasnt a Drop it was $6.15 a pound for 1.5 Inch diameter. 1 POUND per 1.5 Inches. So yeah.. 12+ dollars for this 3" piece.. (OUCH)
But the guy didnt charge me for the cut, and gave me a deal on the other metal I bought so it all worked out.

Drilled a hole prior to Tapping it



Tap Tap anyone there???


That right there looks to be 1.5 or so.....


UGG.. me make ball that is square.



Chunk of threaded rod previously turned down for different things.. with smaller new shiny threads!


Hokay.. here we are ready to spin it up and make a mess from the brass! (Man that stuff is messy compared to steel and stainless!)


Zipping off the corner


Like cutting balsawood with a 1/4 inch die grinder!!


Getting there... need to slow down the speed of swings, and depth of cuts.


Coolant (WD40) not just for cooling... but to keep the samn Brass Sand from landing on my arms when Hot...  I should tell myself to put the damn shield down.


Pretty Round I think...


Scotch Brite anyone? (about 1 minute or scotch brite)


Ohhhhhh Shiny!!!!  about 3 minutes with the polisher.






OK now..

Need to make the hole in back larger so I can tap the thing with my new shiny 5/8-16 Tap :)
But there is no chart I could easily (im sure its out there) find to tell me the size to drill it to, so it would tap properly.

Sooo I bored it slowly larger until I had the tap in it, and the cut threads in the taper of the tap were just entering the hole. (This was like 15 tiny boring passes later... pun Intended)




Live Center.. Plus tap.. plus tiny wrench plus hand turning the chuck=Tapping away.




You can almost see the threads in that hole..
I forgot to take a pic with the arbor in it...
cause... well... I was very irritated.
The arbor is threaded crooked...... YES I was warned of that. It was crappily made. SO once it was screwed in it wobbles at the tang a good QUARTER OF AN INCH.
Its sooo mal-cut you can roll the arbor on the table and the threaded shaft wobbles around.



More to come once I have time to breathe!!

SPiN,

Nice job on that ball truning. :thumbup:

My first ball didn't turn out that round, it was more of an ogive(sp?).

I like turning brass better, it doesn't have the curly swarf like steel does.

Hey, again nice job on that ball. By the way get yourself a Mchinery Handbook. In it are formulas for figuring out the size of drill you need for taps, plus lots of other machining info.

THANKS! Guys!

Sorry its taking so long. It seems I have a project for SWMBO tomorrow when I get up... so I may not be able to get into the garage till late, or even Friday :(

BUT.. Next step..

Drill the pivot, and slot the shaft, and umm cut down the end of the handle to fit inside the slot in the shaft.
And of course make some screws of some sort to keep things in place...
brass bushes for the nose and pivots.

If I could figure how to do it, I would put a bushing on both ends of the drill shaft. But I think I may just go with one longer bushing... Im thinking 1.5 inches or 2.
I think I wil lap the parts before doing the bushing so the shaft is "ground" to fit LOL.
<jots not to buy lapping compound next time past the automotive store>

WELL Sorry for the delay.. I went ahead, and got some shavings created tonight.  :dremel:

FIRST..... THank you for the suggestions on getting the tool body mounted properly.

I used the Bogs method, and as suggested it was a snap. (Doddle?  or Dottle?)

First mounting it was a little bit off.. so then I adjusted it sightly.. and VOila it was dead nuts on. 4 pics to show LOL..  :worthless:







Next step for me was to make sure I drill it in the proper spot. The slot is 2 inches wide. The end of the body portion was .8 inches. Sooo I needed the hole 1.8 inches inward to get to the right spot.
Wobbly Edge finder

Wobbly in use



Next up needed to move inward after finding the edge of the vice jaw .314 so that I was in the proper position for drilling the pivot. ANNNNND I measured it twice....... and went .414  :doh:

Here I am making a flat spot with a end mill before drilling it.



Drilling the pivot


Drilling the access hole so I can get into the center to put the bolt in.


Widening the non-tapped side to .25.


Tapping the hole for the pivot. 1/4-28.


Drilling AND Tapping the shaft the chuck will mount to. BEFORE I CUT A SLOT IN IT!!!!!!  (I can be taught)



Here we go... stuck a very tight fitting Allen wrench into the hole (I check to make sure it wasnt bent first with a machinists ruler and light) and then used my dial indicator in the mill to make sure the hole was at a right angle to the incoming slot.
Then Used a .25 mill to mill the slot in the shaft. I plunged in about .1 or so.. while cutting sideways.. so it wasnt a complete plunge cut. I find it cuts a slot a lot easier if you are moving sideways while slowly deepening the cut. Then I make a pass back across the slot making sure its the right length. Then repeat getting deeper with each pass.





And here are both shafts... I need to now cut down the lever so it fits into the slot, and is ready to do its work.
Going to have to make myself some jaws I think, so I can hold the hex in the vice properly. That or I may just chuck it in the mill and take the points off the hex. and then lock it in like that. Need to ponder it first.


If you notice.. the shaft that is slotted.. is now all galled.. and has some scratches in it.
I decided to be slick and LAP the shaft with lapping compound.
It was a good idea......... BUT.. I was a tad.. DUMB.  Turns out there was a tiny piece of swarf.. .and it fell onto the shaft as I was lapping it. Of course.. I was hand lapping for 5 or so minutes.. and things were getting good.
Then I decided to POWER lap it... by turning the lathe on.... worked good... nice... BIND.   Uh Oh.
Soooo then I commenced the next 30 minutes carefully tapping the shaft out with a punch.
The shaft had a nice scratch down it as did the hole.

SO then I had to commence with about 45 minutes of careful filing to take off the scratch and some work getting the hole smooth in the spot it bound up.

Now things are back wehre they were.. but it was a bear.

Next......on my list...
finish the handle.
make the bolts to hold things together..
Bore things out to have brass bushings in the handle and shaft.
Cut a JT-33 end for the shaft

Make a MT-2 Arbor with a 5/8-16 thread... as the arbor I bought for 3 dollars is not true.  :doh:

That is looking like a really nicely executed project, nice clear pic's too  :thumbup:

Bet it's gonna be a great tool to use when it's finished... :dremel:

Hoookay,

Sorry for the delay in posting this item.. but honestly.. I have been deep in   :proj:

The peck drill is DONE.. and what follows is a posting of the little gem now that its done.
I have been using it a TON, and actually.. I use it for almost all holes I need to drill while On the lathe.
Granted.. I discovered using it for a big 5/8 Hole is NOT a good idea.. only because the bit caught, and it spun the thing smack against the carriage. I hold it lightly, and am off to the side of things, as well as holding the handle lightly. I don’t like forcing things.. When the drill bit caught it was out of my hand before I could blink.

SO.
Be careful!!!!  I had to drill more holes, and used my 1/2” MT2 Chuck after that for the remaining hole.

BUT… enough of the health and safety speeches.. ON TO THE PICTURES!!!

First thing I needed.. was a way to hold the hex handle in the mill vice so that I could drill the hole properly on the flat. But it’s a hex… sooo how the heck do I mount it in the vice???
And as I am still new.. I thought long and hard.. and decided to make a fixture to accommodate that. Of course.. after I finished it, it dawned on me that people have those already…  :doh:

Fixture to make handle pivot:

Starting with a decently thick chunk of aluminum I put my dovetail cutter in the mill and decided to see how it liked aluminum!


As you can see No sweat.


Little cleanup with my tiny End Mill

Make it square


Voila… nice and square with a groove. What you don’t see is the pic of me cutting that in half to make two of them.


Tada!! New Tool in Use! Drilling that pivot hole.



Pivot Bolts, and Bushings

Next up to make were all the pivot and slide bolts.

Turning  a 316 Stainless rod after tapping it..


Pre-finished bolt, longer than required.


Here we have the bolt through the shaft with extra sticking out. (the additional clearancing I did in a in-between step fitting the handle and the shaft to get maximum throw. Doing this again I would have put the pivot further in and made the slot wider, as well as the bevel in the handle)




Quick spin in the lathe and the ends are trimmed down to be flush with the shaft.


Trip to the hobby shop down the road and some brass tubing was purchased that was ¼” ID. Sooo a little spin in the lathe and a little persuasion with a sharp edge file.. voila Bushing.




Handle Trimming:

Next up.. the handle needed to be trimmed in the mill so that it would fit into the slot in the shaft.
The handle was then chucked into my new V-Block thing.. and I got the edges with the edge finder, got the middle with a little math, and then I figured how far to mill into each side of it. (of course accounting for slop in things since I was cutting from two different sides, and measurements were a little fun)



Final pic of the handle with the bushing and bolt made for it.



Main body bushing:

The next thing I figured I would need, Was a bushing for the main housing. This is what I was thinking after reading about Bogs repairing his tailstock etc. I figure any vibration etc will result in wear at the end of the housing.. sooo Making a bushing long enough to support the shaft would be critical as a wear part, and also to prevent galling between the shaft of mild steel and the body that is stainless.

I started with a .99 Cent double ended gas fitting I chucked up and turned on the lathe.


After measuring the outside diameter of it I bored the main body out to slightly smaller than the diameter of the brass bushing… and to be 1/8 inch or so too shallow depth wise.



I made 5 or 6 passes without changing the lathe settings to make sure any deflection in the boring head and or lathe carriage was not leaving the hole tapered. The second pass brought our a small pile of stainless on the boring bar, and subsequent passes resulted in less with each time, until the last two were clean.

A firm press by hand got it in about half way. From there I used a 28oz persuader to help it seat properly.


Little clean up of the face and she is ready to bore.


Boring.. boring.. boring…  Man I have the cross feed at its SLOWEST.. it does cut real smooth.. but it takes forever.


Result??
Ohhh SHINY!




Taper Time!!

Sooo I needed to bite the bullet and figure how to cut a taper.
SO I listened to the posts and advice.. and did what was suggested.. Mount a dial indicator on the cross slide and adjust till you have 0 deflection.


Result??  JT-33 Taper on the shaft!


I also did the same for the tailstock MT2 taper. As the original was/IS crooked.


BLINGIFICATION!!!!

Ok could I leave it a cylinder of stainless? Of course!!  But I have some neat tools.. and here is a perfectly good excuse to use them!!!

SOo a quick change of tooling.. and the ball turner goes to work!
How about a little radius?




And lets round out the snout!




Not bad…



A little work with the polisher and here we are:


Retracted:


Extended:




NOW.. what you don’t see is my utter frustration when I tried the damn thing in the lathe… and the threaded store bought MT-2 to 5/8-16 arbor was so badly off.. that the drill chuck was off by a HALF INCH at the chuck end when retracted!!!
I then took the next day to make my own arbor, and Point thread it myself. Yep.. the first time I ever point threaded anything. And it worked.

Here it is in the lathe…



Think its Accurate enough??  That’s a ¼” chamfer with a sharp point.. and a small spotting drill. I let them touch with the cross slide not locked down and moved the lever and they stayed point to point.





End result sitting on the lathe:


I will try to compile a video clip of it working. THe shots on the mill are DARK as I didnt have a light for the mill. (Im working on that one too)

Spin,

I am amazed how far you have come on with your machining over the last few months.

At first it was pure metal murdering, now you have it jumping thru hoops.

Wonderful end product, and many congrats to yourself for mastering the fine arts.

Thanks SO Much guys!

Working hard to get myself up to speed and be able to make things with some sort of accuracy, and finish.
I think Im on the right road with all your help.. and for that I will always be thankful.

And with my overly large pictures (re-sized a ton smaller to where they are now) and the documentation I try to pull together.. hopefully I can give some back to others!  :D

Ok now to get a clip of the drill in use!!

Try uncoated drills, the shiny ones, if the swarf sticks. Might help.

Thanks guys!

The tune was from the middle of "La Villa Strangiato" from the album "Hemispheres".. by the three man band Rush. Actually one of my fav tunes from them.  Im a fan of the era of Farewell to Kings, Hemispheres, Permanent Waves, Moving Pictures.

SO I have been thinking of a problem with the peck drill.... 
Bigger High Torque drilling.. I get a bit of chatter before the bit bites, and starts to drill.

Watching the clips you will notice that the chuck rotates slightly when it engages. This is because of a slight amount of slop in the joint between the handle and the shaft.
I think I am going to have to take her apart, and add a bush between the sides of the handle, and take that slack out of her. That might prevent any sort of chatter when starting a bigger hole.

Scott,

I have also noticed the slight rotation, never really issued me because I only use it on very small drills, but I think I have the same picture in my head about the bush of which you speak  :med:

I'll have to do such one day.... But, Model shows come first ehh!!?   :D

But of course!!!

I was out there tonight making shavings.. and the bushing never entered my mind.. LOL

I was cutting up the 32" long tool steel bar I cut a nice long dovetail in....  :D

Then milled one side true.. and now I need to make a Bogs Mill/Vice stop.....

Oh and had my youngest get out the engine stand, and clear off the junk on the side of his 13B engine, and mount the stand head to it... Gonna let him disassemble it tomorrow.
