how to use domino to make 3 way miter cuts in 1.5  inch stock
The manual shows setup for 2 in stock. I need to use 1.5 inch stock. What size tendon and where to make plunge?

The stock I used was 26mm (just over 1"). PM me and I will send you some info. which may or may not be helpful to what you're planning to do.

Remember that the critical success factor in a three-way mitre joint lies not in the dominoes but in the mitre cuts. Both Tage Frid and Ian Kirby have written about this topic.
