Building a model railway baseboard for no.1 son.
Board will be 8x4 or slightly larger 50mm celotex suspended from ceiling by some sort of winch system to lower and raise out of way.
Looked at bike hoists - cheapies say Max 20kgs so if I have 2 sets (4 cords 1 per corner) that gives 40kgs. Mechanical advantage of bike hoists should halve that so lifting pull should be doable by no.1 son but fears of uncon trolled descents are troubling me!!
Any better ideas? Thoughts? Experiences?!
TIA
