More progress on the y-axis assembly.

It's really coming together. It looks great, I can't wait to see it run.
My redesigned gantry will be very similar to your design.

That looks really sturdyI am a bit envious of the linear bearings.
Are you planning to connect the top and bottom gantry tubes with a diagonal brace (or a thin sheet metal front plate)? Not sure if necessary but then you would not solely rely on the bolts of the shear plates.
Right now, I'm not going to add a plate but later if I encounter an issue I might. The cross pieces are 2"x3"x1/4" steel tubes and are pretty sturdy. Each end is attached with 6 bolts (4 back side, and 2 front side). The triangle support has 2 bolt attaching it to the x-axis plate and the back plate also have 2 bolts each.
I'm using 1/4"x3/4" 28 bolts and torquing them down pretty good.
I've spent most of the day so far on the y-axis and have the right side all done and have started in on the left. I have a few more hand drill holes to drill after aligning everything.

After 11hrs of work on the y-axis it's pretty much done except for the rack and pinion stuff.
