I have a set of machined knobs on the HVAC in the GTO. They are quite nice but are smooth and sometimes can be a PITA to control because they are slippery.





I was thinking that knurling the outside edge would both look nice and be functional. Does anyone have a lead on where to get this done? These are Solid Aluminum Billet and the inside has a taper so that might present a challenge...

Thanks,

John

There's hand knurlers out there but not cheap.

Yeah I looked into it but for a one time use, I don't need to own, and I'd like to not have to buy another set of knobs....

Find a place that specializes in round work. May be hard to get them to do it though. They likely won’t want to fuck with it for the hour shop rate they’ll charge.

Thats a worry, its a small job, not much money to be made.

What about a coating? Some sort of adhesive strips?

What about masking a ring off on the knobs and hitting them with some clear rubberized spray a-la plastidip?

I'm not opposed to it, but I'd prefer the knurl...

Back in another lifetime when I worked at a machine shop I used to knurl big rollers like this on a lathe



God if one skipped or it started knurling over a section that was already done it was such a pain in the ass to fix :rofl:

shrink tube...you can even get fabric shrink tube.

This is what I used on my fishing rod handles after I balanced them:

Only issue would be the edge, used a smooth bad of HS tubing with adhesive to finish the edges

Hmmm what about electro etching the outside. Mask off anything you dont want etched and throw it in a salt water bath with a cheap battery charger
