In Tool making I learned the value of using angle plates for accurate grinding of steel parts, so I made these two angle plates for my wood shop to maintain the accuracy when drilling or sawing on the band saw. They are both dead square with the base. The first one is used on the drill press for all kinds of parts- like even long legs- where I want a hole perpendicular to the surface. I have done 30" long parts on it and I could find no better way to hold them.
The second plate is for the band saw and it holds parts square with the table so the cut is the same on both end of a long piece. I use this for all my curved cuts on my utility boxes. Some times I clamp the piece to the angle plate and sometimes I just hold it there by hand to insure a straight cut..
These two angle plates get used all the time. They are made from high quality 3/4" Baltic birch plywood and are unfinished
