right angle micro screwdriver for trim pots?

[coppercone2]

Does a right angle screw driver exist in the form that it is a rod with a knob on top that when you turn it it will rotate the bit? Normally this mechanism would not be useful for anything but inserting screws prior to tightning, but it would be useful for potentiometers in bad positions, so you don't need to take the board out.

I thought it might exist as some watch maker/weird mechanical discipline tool

You mean a wrench with bits? Yes, it exists.

Unfortunately too large:

I would very much like to have that for 4mm bits or Bernstein interchangeable alignment tips.
But have not encountered anything even close.

Probably not small enough

Maybe have to make your own.

well like the last one, not a ratcheting one, its just a trim pot, so I can see a knurled knob at the end that you use to turn the pot folward or backward on the other end

do you know where you can find tiny brass? gears that can be put on the edge of long pins to make this?

I figure a good one would have 4x bearing, two shafts, and two gears that interface at a right angle

then you make a T shape with tubes, that one shaft in in handle, the other shaft is in the top of the T. Or maybe just plastic bushings would work since its low energy.

are there suitable watch gears? or something from model engine kits/precision scientific gearbox kits/etc?remote control cars? hot wheels?

I think it needs those cone shaped bearings that provide right angle interface power

I would buy a gear, but I am not trying to make a tiny gear like that.

I need this


but really really small

A Scalextric rear axle is probably a good place to start.

[coppercone2]

is this not a part used to wind a watch? It must be, when you rotate the thingy to wind the mechanical watch.

Maybe that part is strong enough? its small enough.

Can spare parts for some big ass WW1 captains pocket watch have this?

I feel like a hole measuring tool that machinists use is a good starting point for the mechanical structure also

And I might be over thinking it, I wonder if you can just use a damn flex shaft. If someone knows a  suitable spring thing to use a flex shaft for something with a fairly tight bend radius to make a tool like that... I think it could work.
