bike building jig

[naughtyboy]

heres a bike frame building jig i put together today.
its a combination push/motor bike jig as i can see m/bikes in youngest boys future.

its made so i can fit crank and head tube then build frame from there.

it all packs away flat.

stuck ready made frame in it just check it out.

aready thought of one mod i need to make.

any other mods/ideas welcome.

good looking jig I think I would be tempted to add a brace of some sort to the head stock mount as with that amount of leverage it could get moved about with an accidental knock or the heating/cooling distortion pull it off where you want it to be.
