Mine arrived today - Much appreciated SimoB thanks for what you've done - As with others don't worry about the screws I would probably rivet anyway.Now I have to learn to drive it .
Seemed like 1 is driven and the other is "passive" it just rolls from the pressure of the grain being pushed past on the active roller.
Looked like there are the 2 adjusters on each end with numbers marked on them that need to be rotated, not sure if the 2 eye bolts are to lock the cam arrangement off, haven't had a play with that yet..
