That'll be an impressive beast when complete at that size - especially if you get some good speed with those 5-starts. Maybe I should switch to them as well, speed is one of my big concerns right now.
What are you going to be doing with the machine? That'll be the biggest decision maker for your Z axis. Seems like most of the setups around here have around 1-2" Z travel, but I built mine with 10". Biggest limitation there is actually the drill bit - I don't trust super-long bits, so I can't carve 10" straight down into a block of material. |
