need replacement idea for hand knurl
as it says i need an idea to replace the knurling on handlebars. I was thinking taking an auto punch to the OD of the stock many many times would work. Any ideas or comments?

Re: need replacement idea for hand knurl
I've taken a chisel at a steep angle(<45*) with several light taps to gouge several lines in line with the piece. I've never used it for handle bars, but, if a punch will work, this works better.

Re: need replacement idea for hand knurl
i know its not the best idea but i have gotten the bars where i want them and put a light tack weld with the tig no stick on the bottom risers it does hold em well and ya can break em loose if ya want to change bars later
ever notice when you hit somethin or someone with a hammer you feel instantly better

If you want the knurls, there are hand knurling tools (big bukc tho) or you can make one from a pipe cutting tool with knurling wheels...

Re: need replacement idea for hand knurl
I just use a small sharp punch I made from a broken pin punch.... I tape off the area and make lines of punch marks about 3/16th apart....raises the material enough to bite....

Re: need replacement idea for hand knurl
guys i have a lathe and a hand knurler but i am doing an article for the mag and want to show guys how to do this with hand tools that they may already have. I think the punch on the bars and on the risers will be the answer.

Re: need replacement idea for hand knurl
Well as your up for Ideas, being that chewing up a set of bars goes against my grain, what about drill & tap a wee hole under the riser and insert one of these...

" being that chewing up a set of bars goes against my grain " ............ You shouldn't be so heavy handed...LOL ..... I use the small ballpeen I have... Seriously the time and gas I would burn finding those , I just use what I have... those that have access to little wonders like that , Sweet ! It's about using what you have...like I save the little worn down scotch-brite pads and use them for engineturning the backs of SS seat pans...no one really sees it , but it is a nice finish...them work good on curved surfaces !

Re: need replacement idea for hand knurl
Low down dirty way to do it is........
Clamp two smooth cut files in a vise on each side of the bar where you want the knurl using soft jaws, then tap one of the files with a hammer, the bars will need to rotate 180 degrees and you will have a knurl.
