First my block is 1 1/2" x 1 1/2" my first cut is 30 degrees then there is 2 ways to make the next cut I on contrasting piece of wood make your 30 degree cut then I measure 1/2" make a mark then cut 45 degrees then the lower piece of the block is cut at 45 degrees.I glued and clamped it in my glue up jig
On this block all the thin pieces of wood are cut at 30 degrees after the glue has dried but imagen you could make them at 45 degree?? Have to try that to see what they look like. Here are 2 photos showing my cuts and glue up if you have any question feel free to ask
