CNC Benchwork

I've been working on some ideas for CNC benchwork for a future project. This is an exploded view of the design that would be used for a shadow box style layout.  However, the parts are somewhat modular and could be used to in various ways. The next step is to get some parts cut and see how they work out

Since I don't have a CNC router, I have to outsource the work. I am currently investigating vendors that provide that service. Stay tuned.

    I have been thinking about 1/4" or 3/16" plywood CNC benchwork as well--seems like it could simultaneously be light, strong, drillable, and accepting of fasteners. Also opens the door for benchwork materials other than plywood, maybe gatorboard, styrene, or some other kind of heavy resin coated board material. Instead of outsourcing, I am contemplating a county adult learning course or makerspace membership that comes with access to CNC routers and laser cutting. Looking forward to hearing about your adventures with this technology.

    I might be a little late with this but given the flat 2D nature of the parts they would be good for being cut with a waterjet also.

      what type of tolerances can water jets achieve?

      Our local waterjet shop can hold +/-.005 on materials up to about .5" thick. Can cut almost anything. Metals, rubber, wood, plastic, stone, etc. Here is a link to the shop we use no affiliation and too far away to be much use to you but has some good info. http://www.streamtekllc.com/

    And what kinds of materials can water jets cut?
