Doing my first big glue up using the Domino XL [scared]. The door has 7 rails and uses 28 Dominos!(14mm x 140mm). I did a test run on one of the rails but it was a real pain trying to remove the dominos again so I am a little reluctant to do a dry run on the whole lot. I can't be on an Island here. The only thing I can think of is sanding 28 dominos and using them as a test for this and future projects. Any other suggestions are most welcome.
