MechMate Gantry & Y-Car Assembly

With the availability of CNC laser cut machine, fabricator's life gets a lot easier then it use to be. BUT that doesn't say one gets a free ride when fitting them accurately.`

Here are the laser cut profiled components. Most of them will be "Lego-ed" & weld into usable Monocoque Y-Car chassis & Box Beam Gantry

Level & alignment is of paramount important in this excercise. 

Hence, I build 2 adjustable trestle from C-Channel off cuts.drill & tap M12 holes for attaching adjustable leveler legs.

Setting up the box section beam on  the trestle.

• Using Spirit level to line them on horizontal plane. 

• Align the box section beam by measuring the parallel distance. Comparing diagonal distance to ensure they are square to each other.

• Clamp down to hold the position.

Rubber mallet for fine movement by tapping them lightly on the correct places without damaging the paint work.

When you are ready, spot weld to hold the assembly together & check for distortion.before doing the final welding.

Here are the Gantry & Y-car after welding & a coat of red oxide primer on the weld.

Closser view of the Y-car, The original paint was severy damaged by welding spatters....Shouldn't have painted...

.....Nothing I can't sort out with a coat of paint.
