I’ve been making things for a while now and one thing I’ve learned is you can spend a lot of time running around for parts and materials. It’s best to get most things by mail order. There are a few things you buy locally like wood, acrylic, screws and fasteners. Here are some notes on procurement and making.
This is the material you find in the bottom of a drawer or is the backing of an inexpensive shelving unit. One of it’s trade names is Masonite. It is great for laser cutting and CNC cutting. It’s easy to find in 1/8″ and 1/4″ thickness. The trick is to go to Home Depot and buy the 24×24″ sheets, or get the 4×8′ sheets. If you get the 4×8′ larger sheets have them cut to the format of your cutting machine. For the 24×24″, I score with a blade to snap in half to fit the 24×12″ lasers.

This is another amazing material that works well for laser and CNC cutting. Some say the cast type (vs. the extruded type) works well with CNC. I’ve found this to be the case occasionally. But do experiments. Have your supplier cut this on their table saw to fit your machines as it is hellish to cut without a table saw. Cast has paper backing which can be left on so the gassing that may occur during cutting will not stain the surface. The difficulty is you have to take the backing of all the little parts you make.
This is another one you get locally as it’s hard to find a deal online. Check the list below for Ottawa suppliers.
