    So far, my CAD efforts have been 100% perfect, every single part drawn has fitted just where it should be Torsionally, the gantry is very stiff - pushing on one side brings an immediate response from the other which is good, the Z axis looks like it will be just as tight.

    Now i need to fabricate an idea for a method of joining the Y axis nuts to the gantry cross-beam.

    Certainly is Jazz, this thing is probably more rigid then 'Mr Flexy' the Bridgeport ;)

    Yes it is, 4" belt vert/horiz, it's one of the most used tools and one of the most gutless i'm afraid, I really need to build or buy a decent unit with a Hp or two behind it. You have to take your time on it - press on a bit and it just stalls out.

    Cheap though and has done a lot of work.

    Slight boo-boo uncovered tonight, the belts arrived and the teeth were bigger than i allowed for in my serpentine arrangement, this caused the opposing sides of the belt to rub against each other at the idlers...

    First option for fixing it was to order up some smaller diameter bearings, should work ok.
