KNURLING TOOL MY WAY

[ieezitin]

Hello  guys.

 I find myself lately just making tooling that I don’t have and refuse to buy. I have an ultimate goal of having a fully stocked machine shop  for gunsmithing by the time I am sixty.

I own a Knurl tool it’s a plunge sideward force type, I hate the way it abuses the headstock and carriage. The squeeze type of knurling tool has intrigued me for quite some time now, I see the point of less work the machine has to do to achieve the knurl,  so finally I got off my ass and made one.

I got plans off the net from another forum, for the life of me I forget where they come from so credit to the initial design is another, if my memory clears up Ill post his name to acknowledge the credit, I do have the full plans in PDF format which I have no problem sending to anyone if they wish, I did not stick too the original plans as I adapted his main design to fit my QCTP Tool holder, there is also some little features I added myself.




I know the nuts look ugly, i have some acorn nuts on order that will tidy up that end of it.






I was running out of Tool holders for my change post so while i was at it i made 3 more tool holders.






I modified it so i can expand the opening or gape, I had the locating pins(they are the ones  fixed on the tool holder) 1.104 on centers and when you want to open the gape it only got to just under an inch, I needed to knurl pieces up to 1.750 dia so all I did was make a riser plate and add another pin .780 further up so this enables me to open the gape bigger.




Here are the results. The top is steel and the bottom is aluminium.













So…. I needed to know how to use the tool, I suspected there was a way to do it so I did my research and found a guy in Australia who has a You-Tube Vid on how he does it, what you do is with nothing running you position the wheels over the work, you gently squeeze the jaws down just so both wheels rub and rotate a hair, then pull the tool away from the piece, then turn your clamping bolt down ( I found mine needed about 1-1/4 turns) then fire up the lathe ( back geared lowest speed and feed) plunge the tool in and make sure the wheels are at TDC, spray lube on and start carriage feed. If you need more depth (as I did) just while its rotating apply some more pressure.

I am happy with it, I now need to buy more types of patterns for it.

All the best…….  Anthony.

  Nice work Anthony 

That'll certainly make your head stock bearingS breathe a sigh of relief, and  it produces nice knurls - well done.

Nice job!

Hi Anthony

That looks good.

I now need to buy more types of patterns for it.

You might not need as many as you think.  With a clamp type knurler you can do diamond patterns with straight knurling wheels just by turning the tool 45 degrees.  Of course there is a downside as it might mean you can't do such large diameters.

nice job, nice tool. I was taught that once you establish a pattern you never diseengage. Your nethod looks good however.

[jmhoying]

That's a nice looking tool!  Thanks for sharing.

[clevinski]

Geeze, you do nice work!

great work, what did you make the pins that carry the knurling wheels out of?
I bought a push against two wheel knurling tool from "the ebay" on a whim a while back, as it came with eight sets of wheels spare....
 but I later found out the wheels on the tool were riveted, so there was no way of fitting the others?

Then when I was "researching" / more like endless web trawling out of boredom I found a interesting snippet of info on push type knurlers , if I remember it read like this
  "were many headstocks of southbend heavy tens in a local  training collage had been ruined/resigned to the scrap bin, because they were used mainly for knurling work"
well after reading that, mine are going back on the bay,! I didn't know they were so bad!
I love your tooling, im making one ,regards chris

[ieezitin]

Chris... and all...

Thanks for the compliments...

the pins i made from a piece of 1/4 Drill rod / silver steel. They really don't need to be anything less or more as the knurling arm takes all the load.

This style of knurling is way better for the machine than the type you purchased.

show us what you make when you have made it.....

All the best......................  Anthony.

I am new to this board and I just saw this...beautiful workmanship...finish has to be near perfect to look good in photographs like those...good design also...

[krv3000]

well dun must of mist this on

[ddoyle]

I got the QCTP set for my HF 7x10 lathe and it came with a knurling tool, haven't had the opportunity to mess with it yet, as I am learning to crawl before I walk. only been machining for about 3 weeks now

[raynerd]

Missed this one despite it being months old, nice job!

[Skyrocket]

well  thanks to this thread I got off my ass and made one  the build vids will be in the "home made contraptions" thread lol

Oh, some porn pictures of a very nice and well done tool - top quality class ! 

I don't know if you belongs to the group that DO care about the "right" diameter before knurling !

IF you do - you can download a program from my website helping you finding that "right" diameter.

There is NO bugs, virus or adds in the program - but you have to know how to install ;-))

ksor,

have a look at inno set here

www.jrsoftware.org/isinfo.php

it's a free and very versatile installer for windows programs like your (i use it myself).

That is very fine work - something that I've aspired toward for years and have yet to achieve.   Ralph

[Ginger Nut]

  That is 1st class work

[steampunkpete]

Truly a work of art.
