Set up the router bit while the cut is 90, then hog off with the table saw, then return the piece to the router table? The Infinity jig is really accurate, but this is a tricky bit, so you want to test it out on scrap, whether or not you use a saw.

OK Harry, What IS your method. Don't Bogart that information, my friend.

My first lock mitre joints were on this box many years ago and only the lock mitre bit was used and went through the very hard Jarrah with ease. A few other projects were made the same way then I thought that because I hogged out most of the wood with a straight bit when making sliding dovetails I would try a similar method with lock mitres using a 45° bit in the table. This was successful, then I tried the quicker way on the table saw but the joint wasn't perfect so the next project went back to the 45° bit after which I remembered the first joints done only with the lock mitre bit and so every other time I used lock mitre joints that is how I did/do them, it really is far easier with the one bit, I promise you.
Whilst not easy to see, I guarantee that I made it with lock mitre joints, further, the wood was salvaged my my work bench when I first set up business and operated from home in about 1967.
I still have the box.

Now that's a fine looking box Harry. I'll certainly try several methods but my first box was done with only the bit and it was a box with trays to hold my table saw blades. I made it with 3/4" plywood and the joint indeed hid the bare plywood edges. Made a nice looking shop box. I did order the Infinity setup jigs mainly to save a ton of time and get either dead on or very close on initial setup. I'll report back after I get them and my PT releases me to get back in the shop. I still have very restrictive movements with that new shoulder although it's far better then day one was....seems the first range of motion to return was hand to mouth and then the ability to blow my nose, go figure......itching to do more than walk through the shop.
