RE: Home Shop Made Tools - TomG - 02-14-2016 Thanks Mike. You may want to practice on some scrap parts until you get the hang of it. No sense risking real parts while learning the process. Tom RE: Home Shop Made Tools - wawoodman - 02-14-2016 How can I mess it up? I'm sure I can find a way; I'd just like to know what to watch out for! RE: Home Shop Made Tools - Roadracer_Al - 02-15-2016 Knurling? Ugh.... let me count the ways I've done it wrong: - the knurling tool isn't square to the work - the OD of the work isn't a multiple of the pitch of the knurling wheels and never settles down into a pattern. - on those cheap-ass 6-wheel/3 pair bump knurl, the axles are undersize, the wheels wobble, and your knurls look like poop. - on a pinch knurl, you install one wheel of one pitch on the top, get interrupted by a phone call, and install a different pitch on the bottom. You get an interesting rectangular pattern with that. - you squeeze the knurl too hard and you get flakes of material coming off the work and the knurls look shaggy. Here's a neat video on making your own knurl wheels from ClickSpring. https://youtu.be/i9pD5vIHJ8M (BTW, are youtube embed codes disabled on MWF?) a RE: Home Shop Made Tools - EdK - 02-15-2016 (02-15-2016, 01:55 PM)Roadracer_Al Wrote: (BTW, are youtube embed codes disabled on MWF?) No. RE: Home Shop Made Tools - wawoodman - 02-15-2016 I was talking about screwing up the heat treating. I already know how to screw up knurling!

RE: Home Shop Made Tools - dallen - 02-15-2016 parts for that knurler really don't need to be heat treated RE: Home Shop Made Tools - wawoodman - 02-15-2016 (02-15-2016, 06:06 PM)dallen Wrote: parts for that knurler really don't need to be heat treated The only parts that would get it would be the knurl carriers. RE: Home Shop Made Tools - dallen - 02-16-2016 I used 1/2" brazed on carbide tool bits to make my carriers out of and didn't harden them, used hardened dowel pins for axles and have never had a problem. RE: Home Shop Made Tools - Mayhem - 03-05-2016 Finally made an arbour for the 2-3/4 HSS slitting saws that I bought. This is the first time I have turned between centres.
