200lbs of CONCRETE! CNC Mill Build Part 1

Video Description

I'm building a new metal cutting CNC - a CNC mill - and a solid base is always the best way to start. Made from 200lbs of high strength concrete, in this video I build the forms to cast the concrete, then mix and pour the concrete in. As I said in the video, the concrete is just the sand / cement mix you can get at the home center, but I augmented the strength by adding extra portland cement. The base is a fairly complex shape with high sides and back, but open on the front for access. The bed steps down at the back to form a sump for the coolant pump, keeping the cutting fluid inside the base. No reinforcing steel: reinforcing is not needed for this kind of casting that will be fully supported on a table. I did use a piece of high strength polyester cloth to "reinforce" the bed, but that was in the "it can't hurt" category and better than throwing the scrap of cloth in the garbage. In the next video I'll strip the forms and we will see how it turned out. ▶️ Project plans for sale: https://ibuildit.ca/plans/ ▶️Support the work I do on Locals: https://ibuildit.locals.com/ ▶️ Patreon: https://www.patreon.com/user?u=865843&ty=h ▶️ Join my Makers Mob for detailed build tutorials: https://go.themakersmob.com/john-heisz-i-build-it/?via=ibuildit My "Scrap bin" channel: https://www.youtube.com/c/IBuildItScrapBin #ibuildit #woodworking Website: https://ibuildit.ca/ Facebook: https://www.facebook.com/I-Build-It-258048014240900/ Instagram: https://www.instagram.com/i_build_it.ca/
