I had planned on using draw bored pegs to provide the tension necessary to hold the long stretchers in place when building the trestle. However my capability to precisely locate an offset hole in a tenon is not up to the job
So I decided to just tack a couple cleats to the inside of the stretchers for a board that could act as a clamping bridge to hold my glue job together. I'd then just drill and peg the joints as I had done previously
The trestle ended up pretty square so I wasn't too disappointed, but I'd have to come up with a different strategy if I wanted to use drawboring for the top.
