Hey CNC woodworkers!
This is my CNC spoilboard design. In this video I talk about the inspiration for my design, why I designed things the way I did, cost comparisons for other options, layout considerations, and then I go over the build process using my machine to make it! I have an Avid CNC, but the concepts are applicable to any wood CNC router. When I was building my spoilboard I had a lot of questions, and I hope this will help answer things, such as "how much spacing should you use for ttracks?". Should you use Ttracks or Tnuts? A vacuum table or regular hold downs?
Download my CAD file and modify it to make your own ultimate CNC spoil board / waste board! My CAD file is done in Fusion 360, which is parametric and can easily be customized for any particular needs.

The things I used:
* Cheap ttracks: https://amzn.to/40DxRCp
* Affordable 20mm dogs: https://precisiondogs.us/products/pre...
* 3/8" downcut bit: https://amzn.to/3LOuLWq
* 1/4" downcut bit: https://amzn.to/48KHPWS
* Also try bits from 2L: https://www.2linc.com

***Update***: Jay Bates made a good point about gluing: once you wear through one layer you just glue on another top! So, you don't have to replace all three layers. Another good tip is to use a quality plywood for the bottom layer to get better grip with screws (compared to MDF). Thanks everyone for the comments and ideas!
Alternative products you can use that I mention in my video (but are expensive):
* Armor Tool Double Quick Track: https://armortool.com/product/48dou...
* TSO Bench Dogs: https://tsoproducts.com/benchdogs/
