Knurl looseness okay?
#1
I picked up some knurl dies a few years ago and am finally getting around to building a knurler for them.  They don't all have the same thickness, though.  They vary from 0.370" to 0.375".

I've never knurled before so I don't know if the wobble will be a problem.  Was thinking about grinding/lapping them all to the same thickness.

Any thoughts?

That variation could cause tracking problems when making diamond knurls. It wouldn't be a problem with straight knurls though.

I probably wouldn't make a holder to the width of the smallest, but instead just make it the standard .375" wide and try it. If you feed a knurl only in one direction, there should be no problems and your tool is good for when you do buy new, high quality knurl wheels from the likes of Form Rol Die or Accutrak.

If you slip in a thin washer to make the thin wheel fit like the other one, you might be able to run it in both directions, if needed. Some 5 thou shim stock should do the trick.

If you can't get one, make one.

I cant see  5 thou will make that much difference changing feed direction , as there will be allot more than 5 thou take up of the backlash in the feed train changing directions .

There will only be wobble if the knurl is loose on the axil pin . End float is what you will have . 


Knurling is easy enough to do,child's play   , just go for it ,mined you there is an old maths teacher out there that wrote  a computer program to carry out a simple knurling operation Slaphead  ,its akin to needing a program to put your socks on in the morning . lol

My feet are becoming too far away from my hands for easy sock application, maybe I could use that "program"  17428 .

Oddly, I'm no taller than I used to be, my arms must be getting shorter. Chin

In my case there is simply much more stuff in the way.

Use to be a straight shot between the arms and the feet. Now there is this bulge I have to work around.

I would be concerned about the quality of the made knurl if one knurl wheel was moving .005" and the other wasn't. As long as they are both the same thickness and have the same amount of clearance in the holder, it shouldn't make any difference in the workpiece.
