Parts for hand ergometer (exercise bike)

[irving2008]

hi,
just noticed this thread, what material and quantities and timescale are you looking at?
might be able to make some of the bits in the evenings after work if that helps you out

For all the drawings posted, unless stated, the material is aluminium, some machineable grade such as 6061 but depends on what can be picked up on eBay/etc. As to quantity, 2 off each drawing (i.e 2 cranks, and 2 handle assemblies comprising 5 parts, handle/boss/axle/2xspacer). Timescale, well I need to get exercising, so ideally as soon as possible, maybe within 4 weeks?
