I fancy building me'sen a bike lift. I know I could go to Machine Mart and boost the Chinese economy but for a start their lifts are rated for less than my bike weighs 
Besides, what's the point of having all this gear and not using it for something worthwhile. I have a basic frame already made up, from 50 x 50 box. I guesstimate the lifting deck will be 2m x 750mm, probably 18mm ply on a steel frame but haven't worked out the scissor action yet.
I already have an old Edmo lift table that's rated for 300Kg IIRC and I know the principle of the scissor action means I don't need a stupidly long ram to lift a lot further than the ram stroke, but how does one decide how much poke the ram actually needs? I could estimate the weight of the lift and add the weight of the bike, but something tells me I'll need 20 tonnes to shift a tenth of that - and anyway I'm firmly in the 'over-specifying' camp so if it needs 20 tonnes I'll fit a 50 tonne ram
Next question is: anyone got something suitable lying around?
I have 3-phase power as well as 240V so that could be an option for the pump.
Given the height of the bike and the height of the rafters I think 1m of lift will be more than enough so probably a ram stroke of 500mm-ish...?
I'm open to suggestions
