Finally the shed is clean or it was this morning anyway.
Well this is becoming a fun project. I played around today and made a trial fit of the column and base. The column is 100mm square RHS sandwiched between two 100 by 75 RHS for the base. A 300mm steel plate sits on the base RHS and has a square hole milled out of it to let the column through. The column has additional support of two 250mm wide plates at right angles. I will cut some shape into the plates once I know where everything is mounted.
See first photo
I will also fill the column with an epoxy and sand mixture.
With everything just clamped together there is no ringing in the steel if you thump it so the signs are good.
The next three photos are of the Hybrid X2 bits clamped in place on the column. I have gained heaps of Z travel as you can see from the photos. That is a 100mm vice on the table and seeing how much room I have I will be looking at a 125mm vice very soon.
Apart from the extra travel of the hybrid table by spacing things as I have the table can travel under the column so there is an additional gain there. I will bolt the X2 column to the steel.
This exercise has been good because I am thinking about the Nema motor mounts and position of the ballscrews and in particular Z axis while I am tinkering.
