I have a new 750x1000mm CNC Router that is ready for fitting a Spoilboard. My initial plans are to use multiple single T-slot channels with alternating strips of wood that are mounted to the sub-plywood base.
The Spoilboard (T-slot channels and the wood strips) would be fastened to the sub-plywood (¾"-1" 13 ply Birch plywood). The sub-plywood would be cut to the frame size, not to the working area. The spoilboard would be cut to the working area size. My thinking is ... I would rather replace the thinner wood strips than the thick sub-board. Is this a good idea or not?
How many wood strips and T-slot channels should I use? I will be mainly cutting materials ranging from 2" thick hard wood to ⅜" T6061 Aluminum plate to PCB to smaller guitar parts, etc. So my clamping needs will be varied. For example, how would I hold a blank piece of rough Cow bone in order to machine a guitar nut? I would consider using a low profile vise to hold the smaller materials.
Which type or style of T-slot channels should I use, i.e., T-slot dimensions? I am planning to mount the T-slot channels directly to the sub-plywood as as well as the wood strips.
How does this play? Suggestions?
Later,
Billy
