I did a search and did not find much information on where to buy the blue machining foam. I believe I read that you can get it a Home Depot but I have not seen it. Is there a manufactures name or a trade name for the foam? How easy does it machine? I have a rockcliffe router that I am still experimenting with and I want to use the foam before trying out my code on wood.
What about machining wax, why is it so expensive, is there a cheaper alternative?
