knobs for 1/8" shaft dia.

[Dave Boland]

I need some decent pointer knobs for pots with 1/8" (inch)
shafts. Have found some, but too large and tooooo expensive
(>$1.80 each). Anyone got a good source for these or other
good idea? Heck, even the 1/4" to 1/8" converters are
expensive. Ain't miniaturization grand??


Thanks,
Dave

We had the same problem with 5mm shafts and 1/4" knobs. We would up
drilling out 1/4" #8 spacers to 5mm. You might consider drilling out
1/4" rod and supergluing it to the small shaft.

I make my own by filling an empty toothpaste cap with epoxy.
I drill it out, drill and tap a side hole for a small set screw.
I've been doing this for 30+ years.
Makes a nice, narrow profile knob.

Mine all have tooth-marks in them from opening the tube with my
teeth...

It shouldn't have to have those ;-)

I like the laboratory workers' way of opening this kind of container
with only one hand: hold the tube with the "lower" 3 fingers, then use
thumb and index finger to unscrew the top. Trains your dexterity
quite a bit --- which may come in handy next time you have to solder a
wire in the field, with no "third hand" tool at hand, so you have to
manipulate 3 or 4 objects with only two hands ;-)

Thank you all for the help. I'm especially amused at the
idea of using a tooth paste cap. My problem is that my cap
is a pop open
(http://www.colgatetotal.com/app/ColgateTotal/US/Products.cvsp )

So I was wondering if I could make a cap from a wine cork
(have a few of those)??

I can't think of any reason why not, other than how well it can grab
the shaft - I wonder if there's some kind of plasticizer - or maybe
drill a 3/16" hole, fill it with epoxy, then drill out the epoxy to
1/8". And leave the outside just cork - over the years, the knobs
will "acquire character." ;-)

Cheers!
