Hi All,
Went from “it’d sure be handy to be able to machine 4x8’ plywood into furniture” to ordering the parts kit from V1 and printing the parts for the Lowrider v2. Getting close to finished, figured I’d log my build for the benefit of future lowrider enthusiasts!
Plan is to be able to cut 4’ x 4’ (half sheet) of plywood at a time, flipping it if necessary to do the whole sheet. The build table is therefore going to be 56" x 63" if I remember what the calculator said. I ordered the kit with the mini-Rambo.
I ordered stainless tubing from Metal Supermarkets in Kent, WA (which I was able to pick up in person the next day. There’s a forum topic on the subject, which evades me at the moment.) These things had some NASTY burrs, which took a while to remove with a file and a Husky brand pipe deburring tool I picked up. I probably could have used a dremel with an abrasive bit to do this faster.
I printed the plywood part DXF’s on my printer (a 13"x19" printer that I haven’t used in years, so it was happy to be appreciated!) I imported them into Fusion 360, via the create Drawing functionality, which wasn’t super obvious but I got it to work:

Next I attached those to plywood: oak 1/4" for the 611 plate, and 1/2" baltic birch for the Y sides. I cut them out with a bandsaw, jigsaw, drill press, and finished on a spindle sander:

Printed all the parts, some in black (amazon generic brand PLA) and the blue (Hatchbox brand PLA.) 3 shells, 30% infill, .28 layer height, no surprises. Actually, I was surprised that there were no surprises; each part was correctly aligned when I imported them into my slicer. Truly an excellent design.

Assembly at this point was basically a snap. Be sure to measure the screws etc, as there is a mixture of metric and SAE hardware, which confused me at first.

For the wheel assemblies, I didn’t have to use a rubber mallet or anything, the bearings press-fit into the wheels by just putting them flat on my table and using hand pressure.
Making the plywood parts accurately is vital (holes drilled in correct locations.) I used a center punch and a brad point drill to make sure there were no surprises there. There are a few edges I needed to trim to get the parts to fit exactly right.
Can’t think of any “gotchas” other than the V-rail attachment (cable holder) was confusing until I realized the long-ish 6x32 screws go downwards into the steel pipe.
Next up, build table. I’ve milled the lumber (jointer, planer, and table saw) to be straight and true, shall update the post as I make it.
Then, electronics, movement, and eventually, celebration! Thanks for the awesome design.
