I'm planning on building my own version of the JGRO router. I love the design and have found a few improvements through this board and talking with some guys I work with. Anyway, I can't figure out the purpose of the base support structure. I think it's used to tighten the frame of the machine and to add weight to keep the machine steady. I searched on this and didn't find anything explaining the purpose, just some that didn't build it.
Can anyone provide what it's used for?
Thanks,
