I like to do picture frames but doing the miters was a real bear in most cases. I did some reading and found about this basic sled idea. if the triangle piece is accurately 90 deg then even if it isn’t squared at the blade perfectly the two cuts will still add up to 90 thus preventing gaps. All you have to do is keep track of cuts, name them side 1 and 2. as long as every joint has a 1 and 2 you are good to go! if i can get an accurate repeatable way to measure inside the rabbit so i can get repeatable lengths I am set.
Materials are a piece of 16”x36” melamine shelving, 3/4” hardwood square stock, a small scrap of 2”x4” and a few assorted screws. Use countersinks to keep a flush surface, a little paste wax to help smooth out the movement, and finally a coat of varnish on exposed wood to keep the water out. All pretty primitive and cheap, but should be effective. Depending on how well it works out a crosscut sled is in my near future with a similar construction technique.
update now with clamps!
update #2 I took aluminum angles and attached them to the sled where the piece to be cut would go. In the last two pictures a stop block is clamped in place to ensure the length of frame is set. Once you cut the first one and like it just put in piece number two and it will be exactly the same length. This jig should hopefully solve the two problems with mitered frames: 90deg corners, and having repeatable side lengths.
