Re: My µBITX in its new home

Jim Sheldon

Mainly 1/2" or 9/16" OD knobs. Would like to find matching 3/4" and maybe 1" OD knobs but with 1/4" shaft. Those will work for 6mm shaft too but they will be a tiny bit wobbly. I can live with that.

Sorry, I should've been more clear. I know the shaft size, what size knob (outside diameter) were you looking for?

The µBITX volume control knob is 3mm rather than the standard 6mm (or
1/4"). However, even the 3mm knob I have seems may not
actually be metic, but a 1/8" knob.

What diameter knob are you guys looking for?

Nope. I couldn't find one either. I've taken a knob for a 1/4" shaft,
some 1/4" diameter Nylon rod, drilled the center out of the rod, drilled
a hole in the side of the rod big enough to pass the set screw and cut
the rod to length so it remains flush with the bottom of the hole in the
knob. Run the set screw down far enough to hold it in place until you
get ready to mount it on the pot shaft. Usually you will have to cut
the shaft of the supplied pot to the right length as well. Caveat, make
sure you don't cut the shaft too short - LOL Fortunately that happened
on something else long ago and I haven't forgotten the lesson.

. BTW, am I the only person finding it difficult to find a knob for
the small volume control?
