Yes Richard
I use the aluminum stock to line up the stab and it works every time as long as they are lined up perfectly straight. I really can't do it any other way because my building board is to small. So it really works like an extension of my board.
Of course it would be much better to have a bigger building board but my room doesn't allow it. So for now it will have to do, but I always dream about a decent 2x2m board. Oh well, someday.... someday
