Adding knurl to steel
Hi all,
If I had a length of steel roundbar, how would I go about adding a knurl to the ends of it? Is there a tool that you can buy to do this that doesn't cost an arm and a leg?

When you use this tool you need to make sure that once you start knurling you stay in contact with the metal until you reckon you are completely done. If you disengage to check things out then you don't always re-engage in the same spot and you'll just mash the old knurl. So, if you want to check out how the knurl is going, leave the tool on the metal and stop the lathe.
To knurl a wider area you can move the tool along the steel with the fine feed, provided you stay in contact with the metal it will maintain registration OK. I move it up and back the full distance I want the knurl and then apply a bit more cross feed pressure and repeat until I'm done.
Depending on what sort of steel you have you might have to apply quite a lot of cross feed pressure to get a decent effect but that is OK - that is how they work.
Cheers

Bob,
If you use a scissor or clamp style knurling tool (see photo) the load on the cross slide and headstock bearings is reduced.Cheers,
Rod

- Hold it between centers ensuring it is firm and won't slip in the chuck jaws and firmly supported at the t /stock center end.
- Take a skim cut if possible to start with a good surface ,if you do not have a good surface already.
- Use the slowest speed onyour lathe.
- Ensure that the teeth of the knurl are clear of any build up of any material before knurling.This will wreck your knurled appearance.
- Make sure the knurl is operating at center height.
- Wind in the cross slide and engage the surface firmly.You generally get the one opportunity.Watch for the depth of pattern you are satisfied with, then DO NOT TOUCH IT
- Use auto travel if your lathe is equipped with it,or otherwise move it with a consistent and smooth motion.
That help ?

Of course, if you don't have a lathe, you can get a hand knurling tool - I bought a Knurlmaster last year. It works quite well enough for me.
