I’ve practiced on my Shapeoko Pro XXL now since the first of this year when it arrived. I feel a need to do something worthwhile now and not just practices and tests. I have a 2’ x 4’ piece of birch playwood. I’d like to make something out of the entire piece or maybe multiples of a useful tool made from this piece of plywood.
I’ve tried walnut and have some of that and some 1" rough stock - not sure what it is but it’s very stringy.
I’ve used resin/epoxy with some success. I thought about gluing together two 18" x 8" pieces of this 3/4" plywood and trying to make make-up holder for my wife with various sized holes for her brushes, lipstick, tweezers and other things like that. Even 1 1/4" thickness is probably not enough and needs about 2 1/2". These brushes and things are top heavy and need to fit about 70% into the thickness to stay upright.
I made a few organiser when starting a year ago with birch plywood, There are simple and useful. Here are two of them. First one is finished with shellac and the second is waiting for a black paint. The second one requires a 3d software to round the edges, it was a good practice.
