While my CNC router has been very handy the only space I have for it is my bedroom. This comes with a number of disadvantages, primarily coating all my belongings in a layer of tiny sharp glitter like aluminium chips. These chips are a real pain to clean up especially in my notoriously messy room. They find their way into everything.
I decided to go with a fully enclosed setup with waterproofing for a flood coolant system. I chose to go with flood because air compressors for a mist system are loud and bulky and I wanted to have the option to cut Carbon Fibre without putting toxic dust in the air.
Material wise I went with wood in effort to expand my limited skills with the material. Other things I considered was a welded sheet metal enclosure like commercial CNCs and a 80/20 frame with clear coroplast panels.
I primed the outside with Cover Stain Primer/Sealer which worked great. For waterproofing the inside I used Rustoleum Appliance Paint which also covered well. A more durable option probably would've been Rustoleum Tub&Tile Refinishing Paint but for some reason paint is twice the price in Canada (arrghh). The outside was painted with spray paint.
Things I learned (mistakes):
- I should of spent a bit more to buy sanded furniture grade plywood. Sanding and filling was a real pain and the inside surface is rougher than I'd like.
- Waterproofing the knots in the wood was a pain. I should of pre-sealed them with thin epoxy beforehand. Even after 8+ coats they still have small little pinholes that could allow water through.
- Measure your plywood. The 3/4 plywood was quite a bit thicker than 3/4 leaving a seam on top.
