Knobs That Don't Spin Evenly Fix

Post by MentalPatient » 28 Jan 2018, 22:24

Surely I can't be the only one here that's thought of this. When you put a knob made for solid shafts on split splines even using the metal thingy over the shaft to make up the difference, the knob still orbits on a tilt. Even lining the set screw to bite between the shaft's halves does not get it right. Yep you have to jam something between the halves.

Cut some plectrum to slide into the gap. Give both sides a coat of super glue applied minimally. Slide it in, let set overnight and trim with a knife. You don't have to use glue. Lutherie, or electronics ? I can't decide.

You can get brass sleeves that slide over the splines as well, but this will work too. It also prevents the splines from bending in if you over tighten.

This is a solid idea - always been a bugbear of mine, not having completely even knob turning.

Did you try other materials for the infill to see if it effects the tone? Is a plastic pick still ok for playing metal or would a piece of steel be better?


Sorry I thought this was Talkbass....

I'm sure there are people who could hear the difference between an insert made from ebony and rosewood ;) .

OK, let's not really go there ... .

I have used cut up bits of an old loyalty card (credit card plastic basically). Worked pretty well. I guess I wasn't that loyal to that company after all :-)

Adding a brass sleeve cancels out the plastic making it the "sound of your bass".
Works nicely with a brass nut.
