Default Knobs!

First of all, hello from me - this being my first post and all.

I was wondering if some kind soul could suggest a source for decent quality knobs. I am looking to install an Alps RK50 pot in a simple home made passive pre-amp. However, beautiful bit of kit though the RK50 is, it has a rather non-standard 8mm shaft and all the knobs I can find are 6mm.

Any suggestions?

Cheers and thanks

Thanks, but they aren't really what I am looking for.

The RK50 is a fabulous pot (should be at $500+!) but the 8mm shaft is a real problem. I can only find one or two knobs that fit and those are cheap and horrible - hardly appropriate for the pot. Why on earth Alps couldn't have put a 6mm shaft on it is beyond me.

Maybe check out people who do custom knobs for guitars/guitar amps?

I was looking through a couple, but all I could see were 6mm knobs, too. The 8's don't seem to be used very much unless they're the bottom section of a concentric pot.

I make my own wooden knobs by using a hole saw and go about half way and stop. Then I counter bore it to accept a smaller metal knob with set screws. Then remove the piolet from the hole saw and complete boring it. Then I drill holes from the side to be able to reach the set screws. Then I epoxy the metal knob in the center, put a shaft in it and mount it in the drill press to sand.

Nothing say happiness like wood!

I went to a hobby/craft store that specialized in beads. There were all kinds of different styles from which to choose. I picked up some wooden knobs with the intention of drilling the hole to the appropriate size.
Just a thought...

This guy can do about anything Thingamaknobs

He goes by the handle "Some Young Guy" on AudioCircle and Audio Asylum. They are beautiful and worthy of your pot for sure.
