Delrin

This tool cuts perfectly for me for both CFs and delrin. I use the 16 piece model and the metric version gets me the closest to what I use in my Newell's with minimum sanding of CFs. When I punch my Delrin out a 22mm OD and 10mm ID in one rap of the hammer I need to hit the ID just a few strokes with a round file to slip over the gear sleeve easily.

Those are some very sold hollow punches! Thanks for the link! I have been wondering what everyone was using! I will look into and definitely learn from Sal's experience and pay more now to spend less later

I found these,  the pilot looks cool. Punch the outside first then use pilot hole to punch inside hole.

I have the same set (so does Daron I think?).  They work, but do need to be sharpened reguarily.  I'd get a better quality set (like Lee has), if I was going to buy new ones.

SOOOOoooooo , you guys are using delrin washers instead of the Cf ones ?? Forgive the ignorance please ??

Both.

CoolDad,
I have that same set. They are cheap, but work well. You have to sharpen them every few punches, but they get the job done.
Nowhere near the caliber that Dwight uses, but they already paid for themselves.
I punched out probably 10 sets for 12/0's CF in .120 thickness, but I had to hit them with a diamond bit every three or four hits to keep them cutting.

Still.using cf in the stack. Just trying delrin under the main gear and on top of the stack. Just to really smooth out the drag

GENIAL  !! Sounds like a simple mod that actually works . Thanks for your time gentlemen ..

Daron what were you hammering on?  Dominick

A Log. I found I could do the ID faster with the lower punch instead of switching the cutter.

I have cut a couple hundred CFs and Delrin without sharpening anything. One thing that helps me I think is that I use a piece of 2"x8"x8" softer delrin block that a construction friend gave me a while back. I rap the cutter with a short handled 4lb hammer one time for every cut and it works great. The pounding block is holding up great too and does not dull my cutter at all. You may be able to find a piece of it online somewhere.

The .020" delrin arrived so I got the tools to cut a few. I am putting the .020 on the gear sleeve sprocket and a .5mm CF between that and the gear. Got it all put together on a 533-5 and really feels smooth and strong. I also put a .020 under the Belleville.

I ordered up those punches Newell Nut! Awesome to know how well they are holding up! Now if i can just find a delrin block

I used to use a end grain of a 4X4 about a ft. long. I never dulled a punch this way.

UHMW works well too.

I stole a cutting board from the kitchen a year ago, it isn't Delrin, but its doing a great job.
