Here is how I do it,
Grind the ends at a pretty good angle(together for me),lay a small piece of plastic on the edge of your bench(strait edge) or a 6' pc of plywood,board,etc. With good superglue,wet both skives(angles) it'll take a few seconds to bond.
Put the angles together,line up on the edge of bench,flip the plastic over it, lay a small block on the joint,and clamp for 20 minutes. Sand off any excess glue and its ready to go.
Or use a dab of smoothon if you need a little more time to work.
