I finally decided to pull out the big tools and make a new bed for my Shapeoko. This build is inspired by this project:

I glued two scrap pieces of 1/2″ MDF board together and then routered clamping channels.
The clamp material is solid 3/8″ aluminum rod cut to about 1 1/2″, drilled and tapped for 1/4″ bolts.
To see how well it worked with the DW660, I decided to try milling a scrap piece of 8mm Lexan I pulled from some equipment to make two stepper mounts for my next modification: the outside belts.
This time I’m getting proper “snow”. When I tried this with the slower Dremel I was getting hot flakes permanently adhering to everything on the machine. This time, no adhesion!
I was using a two-flute bit. Probably should have used my 4 flute instead as the final result wasn’t as good as I had hoped. Still not bad. Job run time was about 30 minutes. Could have be 20 minutes if I hadn’t decided to do the full mill on the two big circles and instead chosen a simple cutout approach.
