Sending an update to 1) get feedback on my mistakes, 2) share ideas that might help others, 3) help motivate me to get this done,
This is relatively simple build. No fancy collapsing/rotating mechanisms. Assembling using easy to modify in the future screws, except for the box which also has glue. My goal is to build enough so LR3 is always setup to use. But build in a way that enables some probable upgrades to be easily added.
Tried modeling in OpenSCAD, but ended up abandoning/pausing that design. Instead, have created a somewhat parametric design using Fusion 360. My LR3 will sit perpendicular to most folksā builds (see earlier post), front will be clear, and shelves will be recessed/contoured to allow usage as a regular assembly workbench. Still figuring out vice type and location.

Managed to squeeze some Sterilite containers into the almost a torsion box top, can alternatively insert 12x1 plank and use as a desk extension. Did this by ripping the 2x4 blocking to double up as drawer/shelf runnersā¦

Baby got back! Decided to extend rear to ensure LR3 doesnāt overhang, controller box and vac hose stick out a bit. Thisāll reduce risk of damage, and make future enclosing of the LR3 easier (dust/noise control):
Beyond this sketch, will be adding additional ply sheets on the sides, maybe the back too, to hang/mount stock/stuff, and add shear strength/rigidity. Adding diagonal bracing as needed (steel cables maybe like Stuff Made Hereās sweet puzzle solving CNC).
Legs will insert into openings within underside of the torsion box, will add brackets and bolts to allow tuning corners to be on the same plane. Simple 3"-4" braking-casters for now, can get fancy if/when needed later on.
Dimensioned lower section to fit in 28" opening, so can move/transport in/out house through 30"+ door entry. Outdoor weatherās crap right now. Top will be removable for transport and/or āportableā to jobsite/friends.
Will be running vac, with dust stop collector, similar to bench in LR3 docs. I didnāt bother to sketch, power/controller cords and E-Stop, theyāll be strapped on at the end. Am copying JeffeB (and others) by having a 1-1/2" thick table top (with spoilboard) with plenty of overhang, and plenty strong to enable mounting power/controller enclosures.
