    once you have done the first the sec is alot easyer. the main thing is to get the fork head strate up and down. when you think your so close to finshing it, it drags on for ever with so meany little things

    fully agree there it seems so close yet is so far away, and I have limited time to use the resources I need so it might be a month between buildings on it as the workshop I use I cant use all the time,

    Yeah Im really hoping I did get the fork head straight up and down I bolted the front end down at the angle I wanted with the steering head attached to forks,

    Its quite a mission when I have never built a frame before I keep thinking have I done this right or is this part strong enough and the main one always running through my mind is I hope it dont snap on me

    Ivan - if you're worried about the integrity of your frame, bolt it down to a heavy bench or similar and start levering...

    If it bends before breaking, straighten it and congratulate yourself on having learnt what ductility means...

    If it breaks before bending, blame poor design/faulty materials/poor welding/someone else.....and start again.

    It's often eye opening to strap a frame down and see where and how much it moves.
    There's a scrutineer for a club here in ChCh who delights in showing how much things move...and the bugger's strong too.
    I've seen him break spokes...

    I could be wrong here, but good luck racing buckets with a TZ250 motor in it!


    Had a crack at building a frame many moons ago.

    the frame has been made in a way to take other motors not like my other ones (-:
    what did your home build bucket handle like?

    More to the point - how the hell did you bend the side spars ? And why such an acute bend ?
