Some pictures of the frame welded up over Christmas and the aluminium cut parts have arrived.
The movable bed is heavy 5mm thickness 50 x 50mm box section and modifications had to be made around the brackets and the angle bracing as they got in the way of bolts.
I don’t expect I will be using the movable bed which will become a fixed bed, but if I did and built a Mk2 machine I would change the design and have a wind-up bed with threaded
bar each end connected with a toothed belt low down and a crank handle to move the bed up and down with clamps to lock in position. (I expect some one has already done this
and connected a motor to it as well)
I've added some small angle to the bottom rail, this will be to support two pieces of MDF for a base to the machine for storage and vacuum pump, water & pump and probably general junk
