    Previous to this thread, whilst I was searching through other threads - I came across a table; I believe this was like a material comparison table. But I cannot seem to find it now

    any particular reason as to why those materials?

    Hello Guys, Was wondering if anybody had any information concerning material selection for the wobbler components? Gary - nice wobbler mate.

    Perhaps its the CAD Platform I am using potrays this differently? Solidworks. I have ensured the countrebore is on the opposite side to cylinder.

    CAD so far - I was thinking of having a vertical osilliator - I have found some designs for this on the net. Or perhaps I could scale Elmer's units up to the nearest whole figure. Next step (re-egineering) During my CAD, I noticed the Shaft Bush was slightly over, I had to reduce the...

    So - by the time the cyclinder port has reached the exhaust port the cyclinder should be fully compressed with air - ready to dispense the air, and by the time the cyclinder port has reached the intake port the piston should have no compressed air - ready to get air compressed back in...

    At this exact moment I am writing about Elmer's Wobbler, currently explaing the oscilliating movement. I was wondering is this all that needs to be mentioned in relation to operation. As I believe bore stroke and performance, belong to 'calculations' rather than 'operation' - perhaps the...

    Tin they look amazing! In relation to 're-engineering', I would like to keep to Elmer's design style. However I will be changing dimensions and adding tolerances (this i beleive to be thr tricky part - as if wrong, then the operation of the wobbler would fail). But - yes. I will be taking...
