Ok got to use one of these for the first time today....
It has a few problems , nothing I think a Zombie can't overcome , I wanted 4 pieces same length with 45' angled cuts each end.
A lot of work with a hand held grinder.
Problems were due to clamps mainly , the orange lump on the left cannot hold the mitre square firmly enough to allow the piece to be clamped against it using the clamp on the right ?
Although the angle itself is reasonable accurate [ compared with hand held grinding ]
The clamp on the right rides up the work as it pivots around the tightening bolt.
The base with the cross in is not flat , I had to pack the work piece and use a G clamp to hold it , luckly it was long enough to do that.
So looking for some improvements.....
