In that case, go for it. I would be interested to know how you get on
with such transpants, and which presets you ultimately find most
suitable. Also, how quiet they are in actual practical usage.

I'm interested to know how the OP plans to reliably connect a standard
shaft to a preset, I`m presuming his idea of a preset and mine concur.

One other point, presents don`t normally come in log tapers, do they?

Hi Ron. That is a very good point, and one that I hadn't even considered
when thinking about his original plan to use these. If you look in the
post
that started the thread, he says that he is intending using the presets
that
you can get a 6mm shaft for that turns them into a ( semi ?? ) user
control - I'm sure you've seen the idea on stuff where there is an
adjustment that would be a good idea to have available to the user, but
not
in a way that encourages him to *use* it. The shafts that I've seen
usually
have a lightly splined finish so that they can be gripped, and a
screwdriver
slot in the end. I think he intends to pass one of these through a panel
mount shaft bush, and then persuade the knob to fit.

Ah ok, Piher do a range of shafts for their min presets. I`ve used them
on radio mike receivers etc. to replace the output level and squelch
controls, invariably because the user has been heavy handed with them.
The combined cost of preset and shaft is quite high compared with a
normal pot.

Personally I like the Omeg ECO plastic pots for replacements on gear
that takes standard quarter inch bore knobs, Rapid Electronics stock
the pots with the monkey metal slotted and splined short shaft that fits
a lot of the Chinese product

If you mean the Vishay 12/13mm footprint pots then they are the right size
but the manufacturer's pdfs don't give the wiper dimensions , if of
thickness of a coarse human hair , 150 microns, then little point in using,
as will be back to square 1 in a few years.
