Parts for hand ergometer (exercise bike)

That works for me!

Those renderings are great, really helps to visualise things. What are you using? Sadly there's nothing that runs on Android that does that.

I'll post other drawings tomorrow, need to review them to see if I can simplify them.

Yes 3D models are great for showing visually unfortunately software to do this quickly and easy is not cheap. These are done with Solid works and it's bloody expensive fortunately I have it thru business so effectively tax mans bought it or should say not getting it. . .Lol

Hi Irving,

Let me have the drawings for the gears if you have them (and still want them printed) - got a bit of spare time at the moment (but don't tell my boss that :-) ).

Sorry I missed the update, those look amazing! Can't wait to see them in the flesh...and I am very grateful...

Not been great last few days so haven't updated rest of drawings but will do so later today I hope.

Hi,

Thanks - I still want to go with an epicyclic gear in the long run but the ratio I need to be safe on the design is nearer 4:1 rather than 3:1. So I've decided to go for a pulley/belt approach for v1 of this as was struggling to make it all fit plus the axle was getting increasingly complex - I need to prove the rest of the mechanism first.

I will revisit the epicyclic version in Mk2 as its neater overall, once I'm happy 3:1 will work.

Thanks for your efforts so far....

No problem, it's been interesting.

Let me know if you need anything printing for Mk1 (pulley covers etc).
