I’m planning to start building a Maslow CNC and I like the idea of a Unistrut frame connected to a wall by hinges. I’ve been lurking here for a while, I think I’ve read all of the Unistrut frame design threads. Based on those threads, I’ve come up with a frame design that I think will work, but I wanted to post it here to see if anyone has comments or suggestions.
I have a roughly 13’ wide 10’ tall section of wall to work with. Here are a couple of Sketchup drawings of my proposed frame:
The beam for the motor mounts will be 12’ wide, I’m making it out of scrap steel that I have, the rest of the construction will be Unistrut. The 3 vertical pieces will be attached to the wall with hinges at the top. My plan was for those 3 verticals and the bottom horizontal beam to be 1 5/8"x1 5/8" 12 ga strut, and the 3 horizontal pieces that support the spoilboard to be 1 5/8" x 13/16" 14 ga strut, but I’m having a hard time finding the larger 12 ga strut, so I may have to use the smaller 14 ga for all of it. The way I’ve drawn it puts the top of the workpiece 32" from the bottom of the motor mounts, but I’ve got plenty of space to adjust that if I need to.
I’m hoping to pick up the unistrut this week, as soon as I have some confidence that the frame will work in the space I have I’ll order a kit and start the build.
Let me know if anyone has any thoughts on the frame design.
