: Looking at the picture the first thing I noticed was the blade
: wasn't square. It looked like the blade wasn't tight when you
: made the cut. Then I noticed there were no blade guide rollers.
: If you want to make one-shot scarfing cuts with a bandsaw the
: blade has to be under control.

It is as tight as the tensioner will allow and there are two rollers behind the guard dewhickie thing. Not sure, just know my scarfs have been near perfect so far. It's an old Craftsman saw I bought for a hundred bucks so I am honestly not sure it has all the parts.
