Winding 2 cranks, same direction simultane

The most expensive component would probbably the reverse polarity switch to reverse direction. Found these extremely expensive for what they are.

Ok, but the window motor has all the gears in place ready to hook up... two long cables on two separate hand held buttons so you can control the rate at which the sides go up and at the end of the night turn the battery around and bring it down again. It's the most simplified thing I can think of.

is a good suggestion aWindscreen wiper motor would stand more of a chance at lifting any kind of weight. a window motor is part of a slider mechanism that generates alot of the torque that lifts the window.

Hi guys.

I have sorted it out, I was watching an old cowboy film and was inspired by the old levers on the locamotive train wheels.

With the stands about 2 meters apart with the original crank handles facing forward, i put some clamps on the breaks on the stands, then I drilled two holes in a 2m plank the size of the handles and managed to raise both sides up without too much difficulty, using a sort of rotary bench press technique.

I will investigate the electrification process further though. Thanks for all the advice.

Yes good points guys.

It’s early days right now, obviously in an empty gig you can walk 2 or 3 meters and wind up six inches and then go back and repeat, unfortunately in real life you set your gear up against the back wall during the day but can’t raise it up because the fixtures are blocking the telly etc, so you go back later and ten lads who have been on the ale all day have put a couple of tables in front of your stands and are not moving for anyone, and so yes your right about me making a mountain of a mole hill, but it’s all molehills at the dog and duck sometimes, if I had a pound for the amount of time the drunks block the doors when you are trying to hump your gear in and then ask is that heavy mate etc, so I just try to make stuff as idiot proof and stress proof as possible.

Cheers.
