    The general feeling is that is you can twist the belt through about 45 degrees, that's about right. 90deg is too slack.



    It's not an exact science though as adjusting the tension with any level of precision can be tricky. In practice the twist it method is good enough.





    Cheers.

    You're not the first to point that out and I doubt you'll be the last but I think you're the first to have the proof.







    Cheers.

    Jip, 45 is about what I get too and the belt runns fine, for your own good maybe only have a flang on one pulley, I have on both and its a mission impossible getting the damb belt on to start with.



    Just a little tip.

    That's a good point about flanges that I hadn't considered.



    Over here (UK) it's very unusual to see a craft with flanged pulley on the top, fan, end. I can't remember the last one I saw. We just run with flanges on the bottom one.



    Cheers.

    I usually tune it to the E 2 octaves below middle C, so it sounds like the bass at the start of Black Dog by Led Zepplin- not takin the P- it's true!

    Ignore him, he's just trying to be a member.



    Seriously, though, all these methods need adjusting for the length of the belt - longer belts will want a lower note. On a toothed belt of the sort of lenght to width ratios we use it is not that critical.
