Yeah - I bought a couple of things like this - real cheap mine were and it is reflected in their performance- yours looks like a real bit of kit.
Mine kept winding over themselves somehow so that when I want to hook on at the ned of the night say, I cant pull the cable out to attach to the roof. I actuallyu tore one out of its mounting in frustration at 3 oclock in the morning. . I am thinking about setting the cables at at fixed length attached to each end of the roof (one on each side) to pull in both directions - and running 3 loops around each drum so that it is just a matter of reversing the drum direction and there is no pulling out cable at the end of the night - does this make sense?
I would really like to attch the drums to be on some sort of axle so that I only have one motor driving it - would make it easy. I suppose a length of water pipe would do the job run through some sort of pillow blocks and a couple of belt pulleys from the drive motor to the axle.
Just another gunna job but I'll have to do it eventually - as I get older climbing a small step ladder to get the roof moving then walking along some bench tops as I open it is going to become harder and harder.
