Hi. Just in the final phases of the 3d-printathon and checking what supplies I need for the table/base.
I am planning to have a 18mm ply base and then a 9 or 18mm MDF spoilboard on top (because those are what I already having lying around… probably going to use the 9mm unless there is a good reason to be much thicker?).
I will add the spoilboard thickness to the leg lengths, so he spoilboard just screws down on top of the base. Now, I planning to put a grid of threaded inserts in the plywood base, and then slightly oversized holes above each insert in the spoilboard. Then bolts for any clamps or whatever will pass through the clamp, through the spoilboard and screw into the inserts. Hopefully that makes sense.
My question is about how I manufacture this. Clearly I could manually measure out and drill all those holes, in the base and spoilboard, but it seems foolish when I will have a CNC machine that can do it much more accurately! However, this would require the router to plunge beyond the spoil depth and 12mm into the base, which is presumably outside the designed range of motion.
How’s best to do this? I could build the machine with shorter legs and then replace them with the longer ones once the drilling is done, but this feels inefficient and will mean essentially building and squaring the machine twice. Or will I simply be able to get a longer bit, or perhaps mount it lower in the collet, to temporarily get the increased depth of cut? Or is it possible to shimmy the router down lower in the mounts (I’ll be using a Makita and the V1engineering 65mm mounts)?
