~S~ all

I've finally taken the plunge and manufactured a control box for handling trim out of an old MS SIdewinder Precision Pro and a (hastily assembled) wooden box...

I have yet to tackle gears, but from what I understand, that is about the only way to do a trim wheel. Glad to hear that you were successfull. Do you have any pictures? I would like to see them.

With an extra pully and wrapping a chain round it instead of the thread rods you could also do it this way I think.

I might try something like this.

The pulley idea is a nice one -  a pulley system using rubber bands would allow for slippage when you get to the end of the potentiometer's travel - less likely to break something in the heat of the moment...

I'll take some pics and post - but this is very much a prototype tryout kind of thing... It does work, but pretty it ain't

Cheers,

Silcone fuel tubing as used in model planes, boats and cars can be used.

Many model boaters use it in place of  auniversal joint to connect motors to running gear. For best results drill a hole in each of the connecting metal parts and pin the tubing in place so it doesn't rotate.
