I put blue tape over the end of the t-nut I plan to use because it needs to be free of glue, made sure it was in the correct spot, and then glued the scraps together.
Here they are clamped together.
And this is the drawing I am trying to copy. See how that t-nut is in teh exact spot it should be?
Here, I've cut the block up to match the needed shape.
