Hi Colin. I just seen your video on the left handed tapes. I've been using one of those in the shop for close to 10 years now & really do like them.
I also picked up a General Tools Pro AngleII digital angle finder this morning. I think I'm gonna really like this as well. I used to set the bevel gauge & line it up with the laser on the miter saw & get within a 1* or so which isn't too bad & I hope this gauge gets me there a little quicker.
