Hi All
Well i have started on a new project over the weekend ,more tooling :dremel:, an indexing attachment for the Myford lathe. The indexing atachment was designed by J.A.Radford and i am working from his artical in Model Engineer 5 Jan 1968 (great year) ::).
I thought i would get the worst job out the way first ,the Index plates ,all those holes . I started with some 10mm plate .

(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010472.JPG)
Then i turned up a mandrel ,to mount all four the plates to turn the O/D

(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010475.JPG)
Then each plate was mounted and the edges chamferd

(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010479.JPG)
The original design call's for a set of 4 plates 7 set of holes on each, just short of 1500 holes , FAR FAR TO MANY HOLES, so after some thought ,i decided to cut the number of plates to 2 with 9 sets of holes and only 525 holes , i wil not be able to index 73,119 173 and other daft numbers , i can live with that.
On the other end of the mandral i turned up an expanding mandral to hold the plates for drilling.

The other side ,lots of deburing to do
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010483.JPG)
Still some numbers to stamp on the plates

Rob,
Very ingenious using a hex cut to make it easier to hold the plates while doing work on one side. Excellent set of how to photo's also. This looks like it's going to be another exciting work of art.

CHEERS LADS , :mmr:
I had to use this method of work holding as you see in the photo's i had to drill and counter bore three holes for mounting the plates on the index attachment close to the bore ,and the plates are to large to hold on the O/D, also there would have been problems drilling all the holes and not hitting the chuck jaws .
close up showing under cut
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010493.JPG)
60 deg tapper i used a large centre
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010495.JPG)
M8 counter sunk socket cap , head turned to 60 deg , the origanal 90 deg dose not work as good
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010496.JPG)
And next my quick exspanding mandral,, chuck lump of what ever you have to hand ,as long as it has large O/D than the bore of the job.
turn to size ,and give it some under cut , the one in the photos is one i had lying about .drill and USE A TAPPER TAP ,DO NOT TAP ALL THE WAY, just about the depth show in the photo.The reson for this is so you have tapperd threads
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1010497.JPG)
next using a saw cut 2 slots , leave in chuck. cleen of rag from sawing

just to show what happens as the screw is screwed in

Excellent project, and a very nice photo essay.
Thanks!

Thanks for that Rob, great start on the plates, wow that is a lot of holes! Did you face the plates on the myford and turn them on something else? Was the somethign else a boxford? Can't quite make it out.
Nick
-
Cheers Lads
Bob , thanks,, its best that i use lots of photos as i am no wordsmith :(
Hi Nick , you were spot on , I did face and bore the plates on the Myford, Then i turned up the mandral on the Boxford ,as i had an M16 nut to hand so i needed to screw cut an M16 thread .The Boxford is a metric lathe .
Thanks Rob
-
I like those arbors. I'll have to remember that little trick:o) Thanks.
-
Ah, makes perfect sense now! Good work. :thumbup:
-
Nice setup with the arbors, Rob. Thanks for sharing that.
Tell us, for those who have gone through the bumpity bump of cutting the corners off odd shapes to make round shapes, what are the diameter of your plates, and how fast did you turn the lathe spindle? This is one of my least favorite things, and am happy to hear how others do it.
Thanks for the photo essay. Nice to be able to see what you're doing there!
Dean
-
Thanks Dean
Yep i hate doing the bumpity bump turnning too , the plates are 6" diameter , i turned them at 1000 rpm with a heavy feed ,to ruff them to size,i was in a hurry , chips flying every were ,LOL
I wor a full face shield ,sweat shirt and still managed to get a few hot bits stuck to my neck :(

...
for those who have gone through the bumpity bump of cutting the corners off odd shapes to make round shapes, what are the diameter of your plates, and how fast did you turn the lathe spindle? This is one of my least favorite things, and am happy to hear how others do it.
If you have a rotary table and some way of end milling, this is a much more relaxing way to proceed, and easier on the machinery - you don't need to spend time cutting air; just concentrate on the corners. Can stack up several if you have enough grunt. If you're pushed for clamping real estate, remember your clamps don't need to stay clear of the cutting envelope, unlike say on a lathe faceplate.
If really pushed for space, you can come up with a clamping scheme which only presents one corner clear for cutting; move the workpiece between corners.
If you cut the pieces out to a consistent blank size and shape, it's handy to have a three-point reference, either just felt pen lines on the table or buttons in T slots or some such, to present the workpiece in a consistent position.
The other trick which goes hand in hand with this is to use roughing (corrugated sided) endmills

Why didn't you say you were doing this when you were down last week.
I'd have given you a set of plates.......

Hi Chaps
I decided this year to try and get all of my unfinished project out off the way before i start any more :med: ,, so i thought i would start with this one ,, as i started it just over a year ago :coffee: ,,, Well my plan did not last long ,, all off five minutes :doh: ,, i decided to make the spindle ,,so i centred a length of 7/8 S/S bar ,cut a start and run out groove for the threading tool ,,, then went to set up the lathe for 16DP ,,,,,,,,,,, :doh: no can do ,,,,,,,,,,,,,,, need a different gear quadrant ::) , so i made one :dremel:
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1020973.jpg)
Gets that all sorted :ddb: :ddb: :ddb: ,,,,,,,,,,,,,,,, then spent two hours looking for my swan neck tool holder ,,,,,,, :doh: no idea whats happened to it :scratch:
So made another :dremel:
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1020976.jpg)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1020975.jpg)
Great now i can get going :ddb: :ddb: :ddb: soi made a start on cutting the worm
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1020981.jpg)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1020985.jpg)
Then just as i am nearly finished ,, just as the tool is leaving the end of the worm ,,,,,,,,,,,, crunch :scratch:
oooooooops ,,,, stripped two teeth on the tumbler gears :doh:
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1020982.jpg)
Luck no damage to the worm ,,,,,,,,, so tomorrow night i will have to make a couple more gears ::)
Rob

Rob,
Can you wait until the post gets there Tuesday ? got a stack of those tumbler gears here.
John S.

Isn't that sequence called, "Consequences", Rob? :bang:
Very nice work, on the successful sections mate! :D
David D

Hi Rob
Bad luck :( :( often wondered how those Tufnol gears survive .. must take a hammering when doing intermittent cuts .. I rounded some 1.67" AF hex last year. Abandoned the leadscrew, fed by apron handwheel instead ... terrifying.
What's the t'worm for anyway .. ??
Dave BC
EDIT Ah Lathe indexing attachment ... READ THE DAMN INSTRUCTIONS ....

Rob,
Can you wait until the post gets there Tuesday ? got a stack of those tumbler gears here.

:D sure can John :thumbup: ,i am sure there are other things around the shop i can break in the mean time , pm sent
Cheers David ,,,,,,,,,,,,,,,, heed busting ,, a am going backwards :doh: :lol: :lol: :lol:
Hi Dave BC ,,,,,,,,,, they are the originals,,, 16 DP (5TPI ) was a tad to much for them :whip: :whip: :lol: :lol:
Rob
-
Hi Rob
5 TPI ?? Thought it was not possible to do a thread coarser than the leadscrew ?? Yours is 8 TPI I suppose ??
Surely the L/S is going faster than the mandrel. Or have I got it all wrong ... AGAIN ..
IIRC the coarsest thread I have ever screwcut was 11 tpi .. might have been something like 3/4" BSW long, long ago ..
Dave BC
-
Hi Dave
It is possible to cut a courser thread than the lead screw :dremel: ,but it dose put allot of strain on the gear train :doh: 5 tpi is about max for a Myford
Rob
-
Always happens, just when you are half way thru a job.
I did the same sort of thing with my old Atlas, but actually sheared the heads off the gear central bolts. I couldn't believe how lucky I was, seeing the gears are only made from Mazak.
Maybe you have should have done it using your leadscrew handle, it takes all the pressure off the gears when cutting coarse threads.
John
-
Rob,
Even the gear quadrant and tool are works of art! Lovely work.
It's funny stuff that those gears are made of, I wrecked one of my change wheels trying to get the 3 jaw chuck off my lathe when I first got it, could only find a steel replacement so will have to bear that in mind in future, guess they're made of that for a reason.
Nick
-
Double edged sword.
Myfords claim they are there to quieten the gear train down but the ML7 has steel gears.
The earlier ML7's, non gearbox model, have a two piece leadscrew with a brass shear pin so it acts as the 'fuse', later ones had a one piece leadscrew and steel gears so no fail safe.
If I owned a super 7 I'd replace the 20T and 30T tumbler gear with cast ones as they wear better and go to a two piece leadscrew with brass shear pin.
In the event of a crash like Rob has had it would only be a case of fitting a new pin and carry on with the job, no expense, no waiting and typical lack of Myford foresight to lose something they had.
John S.

HI brill worck can not wate till is all dun regards bob
-
Rob nice work Sorry about crash gears
Why did you make the threading tool holder like that????? And is it steel or ali (would that matter)????
Gerhard

Rob I am also interested in your threading tool holder
I've not seen one like that please tell us more :bow:

I'll leave Rob 'smash it' Wilson to explain it but they were used years ago for finish work on shapers.

Gerhard and Jason ,,,,, The swan neck (some bird anyway ) tool is a very old idea ,, i first laid eyes on one in an old tool catalogue , along with a few other lathe tool ideas that have been long forgotten ,some i will have to try out , :D, What it dose is eliminate tool chatter , as you can see in the photos ,, thats 1/8 deep in stainless and just the ruffing cut . no sign of any chatter :dremel: ,, the tool dose this by raising the centre of the bend radius , so when its under load the tool is deflected away from the work and not into the work as with a normal tool ,, with a normal tool under cutting load it will be deflected into the work , taking more off the work and setting up vibration ,, CHATTER :med: ,, The tool holder needs to be made from a tool steel , mild steel will not do as it will have no spring to it .
Another good thing it the tool uses old worn out milling cutters as the cutter bit :med: ,, well worth an hour or so to make one .
Also a good tool for the shaper . as John (i hate shapers) has just said :thumbup: :lol: :lol:
A few ideas :D ,, old catalogue dose not scan to well :doh:

Hi Peter
Yes there is nothing new there ,, tangential tool bit holders are as old as tea :med: ,not the same as a swan necked tool holder , very top of the scanned page is one shown ,, comes in a range of sizes , and takes square or round tool steel , The date on the George Adams tool catalogue is 1928 ,,, i have earlier references to both tools . As with most things ,with engineering processes/tooling get forgotten about ,,, then brought back as the latest thing as if has just been invented ::)

Hi Lads
Well this project has been sitting in the draw for a wile :Doh:
So today a finished up the division plates .
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1040714.jpg)
And machined up the bearing blocks .
set up for machining the bearing on the lathe faceplate .

Rob,
As per your usual standards, Another great project. :beer: I've got the Radford book so I pretty well know where this is going.
Not to throw your thread off topic, But here's a question I've been meaning to ask. Your standard tool finish is far above anything I've been able to obtain consistently. So what's the secret? Coolant, Metal grade and type, Carbide selection when not using HSS, Voodoo, Praying to the machinist gods? A Myford is a good lathe, But there not close to the rigidity you would get from a larger heavy duty commercial type lathe. Yet it seems your normal finish is comparable to what those heavy duty lathes can produce.

Hi Pete ,,,,,,,,, can i say VOODOO :lol: :lol: :lol: :lol: ,,,,,,,,Coolant ,, yes i use coolant ,,, what ever kind i have just bummed ,, never bought any for years and years .
Metal grade ,,,,,,,,,,,,,, mmmmmmmmmm well your guess is as good as mine :lol: :lol: just one of three draws of mystery bar ends (retirement stock)
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1040716.jpg)
As to carbide tips ,,,,,, what ever are the cheapest ,,,,,,,,, i am not big on having loads of different grades of tips , no point when you have no idea what exactly your machining ,,,,,, threw out the FEEDS/SPEEDS chart for the same reason .
As to the Myford its a surprisingly rigid machine .
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1040723.jpg)
I get just as good a finish with the Lorch Which is a very light watch makers lathe .
(http://www.nam-engineering.com/cm/albums/userpics/10002/normal_P1040725.jpg)
So i would say , a well set up machine , rigid work holding and very sharp tooling , adjust feeds and feeds for best results
Probably not the most helpful answer :Doh: ,,,,,,,,,,,, should have stuck with voodoo :lol: :lol:

yes but this is what He uses for cutting Fluid.. :lol: :lol: :lol:

Well I guess we'll just go with the Voodoo and that the physics of machining metal are somehow just slightly different in your shop. :bang: You do need to give each one of your machine tools a pat on the bearings for me. Their doing a hell of a job.
I've got a somewhat interesting link and further story I'll email you.

Pete ,,,,,,,,,,,,,, :lol: :lol: :lol: not different physics ,,,,,,,, its just by the time you go through looking up all the different tool geometery , feeds speeds and all the rest of the bumf for a one off ,you could have had 3 other jobs done , so i just grinned the tool by eye and set the machine to suit,,, hard to explain really as no two jobs are the same .
Yes in production ,, with 5000 parts in Material X ,, you would want optimal tooling to match X , feeds speeds , correct cutting fluids for X ect

I think you'll find that's for lubricating the machinist. This is my lubricant:

It worksh mosht effifififsh efisiisi eggsegglge well. Hic. The best thing is, the more I lubricate, the straighter the cuts seem to be...

Now this really impressed me no end

We even get that "special" lubricant here in the States, Rob. It didn't look right on the
lathe, so I did something else with it. Worked well enough for that purpose, though...
It's the only shop lube I keep in the fridge.

Same thought occurred to me John. :)
I wondered where Tiny Clanger had got to .. :lol: :lol:

They look first cabin, Rob. Beautifully made. If someone asked what a machinist does, I could just point them to these pictures.
Excellent work!

well dun rob

Cheers Lads :beer:
:lol: :lol: :lol:" tiny clanger" :lol: :lol: :lol: :Doh:
Well made a few more parts ,the index pin .

come on Rob I know you have been asked so many times but WHAT TYPE OF CAMERA HAVE YOU GOT ? no body does work THAT neat all the time :bow:
very very nice work , but I have just sold all my equipment now after seeing you last two and a half projects (mill still not finished unfortunately) as I now realise that I am just a bodger and will never make a metalworker as long as I have a Hole in My (you all know the rest). :bang: :bang: :bang:
seriously nice work.

That's all well and good Rob.... But will it fit my lathe?
I don't think so! Useless it is! :poke: :lol:
Nice shiny stuff there chief :thumbup:
shame you're not hitting Harrogate this year.... Totally screwed up the last time and only got about 3 words in! :Doh:
Hope it all works as well as it looks!? There'd best be a users manual and an instructional video to accompany the end product! :coffee:

Fabulous Job Rob :bow: :bow: :bow:
Shiny as ever :clap: :clap: :clap:

Lovely job Rob :)
Can the spring loaded locating pin be locked back (for use like a rotary table/ 3 axis etc.), on your version?
(I'd like to modify the Victoria on I have so if you have pictures...)
Bill

you is geting too good rob

'
Rob, you can't make those things... You have to buy them. ; )
Wonderful job!

Thanks for the comments lads :beer: :beer: :beer:
(mill still not finished unfortunately)
Cheers Peter ,,,,,,,,,,, :bang: :bang: :bang: :bang: stop reminding me about the mill :Doh: :lol: :lol: :lol: :lol: :lol: as soon as i get the indexing attachment out of the way , i am back on with the mill (i hope) :palm:
Hi Ralph ,,,,,,, I slightly miss planned things this year :palm: and ended up in London for the weekend , I will be there next year :thumbup: what T shirt did you were this year :lol: :lol: :lol:

Hi Bill ,,,,,,, the original design dose have a lock back function ,,,,,,, i have not added it to mine as yet ,i may added it in the future .
Would you like the build artical ?
Thanks again lads ,,, Rob :beer: :beer:

We all have things that get in the way Rob, I very nearly wasn't there, just got a lift in time... Just a plain Tshirt this year. basic description seemed to work quite well! :thumbup:

Sir, that stuff does not look like bought.
It looks way better!
Its just a nice job, every chamfer, knurl and surface comes out perfect.
