OK! The monster IG-88 is coming along. I got the table top all tig welded together this afternoon. This thing is really getting heavy, but that is what a good CNC machine needs: MASS!
There is only .25" clearance between the top of the slide and the bottom of the table top, but that will increase when I get the adjusting feet welded onto the table top legs.
This thing is so rigid. I'm going to get up and stand on the table top when I get the slot-wall installed and see how much flex is in the system. I don't think there will be much.
A cool shot of the carriage with Y axis uprights and table top showing the rigid construction.
