I'm getting my ducks in a row to start building a 4'x8' gantry router table. Will you evaluate my design so far? I could use suggestions/help on motion, too.
Steel 1.5" x 3" x .125" frame with corner bracing and center supports.
Skate bearing glides on Sched 40, .840" OD pipe.
Gantry is 3/4" Baltic Birch construction.
Y axis, pipe is bolted to metal 1.5"x 3" frame along sides
X axis, wood torsion box w/top and bottom .840 OD pipe rails. skate bearings.
Z axis, 2 .840" OD pipe rails with skate bearing glides.
I'd like Y axis to be driven under the table by acme or belt. Acme for the other 2 axis's.
How fast should I attempt to go? What will I need to get me there?
I was inspired by the simplicity of www.buildyourcnc.com.
Woodworking and basic metal working.
10" Table saw
12" Miter/chop saw
taps and dies
lots of steel and wood
I've attached several versions of the same drawing. Give it to me straight
