Spulenturm with mehanical friction

[MarinBNM]

I want to built spulenturm with mehanical friction, because this way is simpler and if something gone wrong is easyl so fix, and DC motor are quite expensive.

 

I want to make whole friction new and conected it to motor via belt drive with cca 200rpm on friction.

 

Other motor gonna be for rewinding conected directly to other rell.

 

I want to ask if someone has experiance with friction which can drive film up to 5000 meters??? Or maybee some drawnings...also on every rell I want to ad dancing arm so that can compesate bad film or bad rells.

 

Can someone share opinions with me?

Use the Dancing arms to regulate your motors like on the Kinoton or IDEF Towers.

I'll check if I can find electrical Drawings

Try to get one of the E12 mechanichal Friktion for 1800 meters. these are with steering arm, going on a clutch, constant motor rpm driven. when the steering arm is falling down, the clutch closes a little bit more an so the reel gets more speed. ist simple to use but a little different to built.
