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.

It's really a moot point though. One can still buy very high quality
pots from a reputable manufacture. That's the route to take rather than
trying to hack in something different. A good pot will last the life of
most equipment. I use Bournes pots in arcade game controllers, they seem
to hold up well to the abuse.


The thread concerns 12/13 mm footprint pots (sub miniature), no problem with
17mm miniature or 21mm standard size ones. I doubt game controllers use
subminiature ones.
