Re: [CAD_CAM_EDM_DRO] Re: Flat as a (very precise) pancake...

Tom,

I am going to use the Bishop Wisecarver Corp. Dua-L-Vee System on my new
cnc router project (Y axis). I have the track mounted on a 3/8 by 4" piece
of aluminum. That in turn is mounted to a 3" by 3" 80/20 type of aluminum
extrusion. Before I attached the 3/8 by 4" with the track to the 3 by 3 it
did have some curve.

I will keep you posted after I get the new system running soon.

BTY, the length of the track is 60.5".
