So I have been using double sided tape to hold my items down and it has worked relatively well except when I cut through the material and tape gets stuck on the bit I have been reading posts and the Wiki on wasteboards with threaded inserts and T nuts. Seems theres are a lot of different designs. I think I want to go with 1/2 inch mdf with T nuts. I have plenty of MDF (Home Depot had 4’x4’ 1/2" sheets for $5.) Then attach that 1/2 on top of the Shapeoko 3 wasteboard.
So good so far? Recommended grid for T nuts? Do I have to sink the t nuts in from the bottom or just mill a hole?
