Norm - no offence at all!
Adding some length to the "loose angle thing" is on the list as is a tensioning bolt for when its trying to clamp on somehting that doesnt go past the point of rotation.
I've managed to get by without having to tension/untension stuff too much. But you are right having to reach for a spanner is wearing thin.
There are other mods by a fellow kiwi that I like the look of which are shown here: http://www.modelenginemaker.com/inde...ic,6363.0.html
I also have some ideas re leveraging this big ass frame to create some flat support/mounting space to the right of the blade (look at the saw from clamp handle end). If do that then I get the ability to mount some big rounds of steel or caste iron to be sliced off in a single cut for such things as fly wheels in a single cut. Where as at the moment I need to muck about with a fussy multi cut process as the boom hits the top of the round.
All good fun.
