a paste from my build thread on another site ...

the basic layout of the bed and X axis....






I've made the bed in the form of a torsion box out of 1/2" MDF.
Finished bed size is 36" x 27" x 4" - max working area will be about 26" x 26"

I've laid the screw and rails on top roughly in the position they will be in, except it will be the bottom when finished.

The gantry will be torsion box sections too , and fixed to the rails under the bed for a clean look.

The bed will be raised on legs when I figure out how high they need to be !

anyhoo,, today I spent a couple of hours on my build.

the rails I lined up on a bit of 3/4 ply, using a new ground level as a straight edge.



I drilled through and counter bored underneath, before grinding off the bolts before tightening









I must say, the mixed sets of machine screws / washers / nuts etc . are one of the most usefull buys I ever bought !



I mounted the motor / screw assy on a bit of ply and shimmed it to be parallel



and this is them all layed out .



I now have to fix one to the bed and set the others in place of the 1st fixed bit.

I'm deciding whether to use the screw as the ref , or a rail .. but I don't suppose it matters much.
