    Can I sqeeze a black theratube, id is 0.200inch (5mm), on to a 11,5mm diameter fork?

    Thing is I got this ferfect shaped fork for my big shot project, but I don't know which tube to use...

    Hi,
    I just tested it with a 4,0 / 6,4mm tube.
    I sliped it over a 10mm tip of a drumstick, works good so far.

    Great! Thank you!
    If you can sqeeze 4mm arround 10mm, I should be able to sqeeze 5 mm arround 11mm.
    Offcourse ringarea is much bigger on the theratube.

    Thanks again, added the site to favorites :)
    Any idea how these relate to theratube in terms of strength?
    Still thinking on how to launch my 300gramm bags 40 meters up in the air... 2 tubes, 50cm each, pull to 2,5meters, LAUNCH

    Maybe you already know this, but you must use alcohol on the tube to make it goes easy.

    You are welcome. Squeeze the tube and let the alcohol in and out. It will dry and let the rubber stuck.

    Hi,
    I have mounted the tube on the drumstick without any lubricant and I got my problems to remove it.
    In the tube-size-chart you find the ring area of the tubes, which is outer circle surface - the center circle surface of the hole.
    So you can make comparisons between different tubes and bandsets.
    I added the Thera band to the chart (just the Thickness) so thickness x width x layers = area of rubber.

    Material is more or less the same.

    I am not sure 1015 was the strongest I found.
    Think the bigger ones are made of silicone.

    the "startertube MR-scale" would give lots of rubber mass.
    I will have to make shure I don't need a pulleysystem to cock my slingshot!

    thanks for the charts man, that will save me a lot of try-and-error!
