I guess I’ve just “splurged” on MPR&P… without really intending to. Took delivery of a portable workbench that I bought just for the heck of it… it seemed a good deal at $79.99 during Father’s Day weekend. Actually it’s $99.99 right now… but could still be a pretty good deal if you’re just needing a handy and dedicated workstand for your ultra-cheap MPR&P, built almost entirely from your MPCNC junkbox. 
Once I opened the box, I realized that I had done myself (and MPR&P) a great favor. This thing is the perfect stand for MPR&P and provides ample workholding possibilities… something I’ve struggled with quite a bit during testing on its current work table.
Just larger than the footprint of MPR&P (22" x 30") this handy work bench comes with 4 plastic dogs and 2 Irwin-style clamps. The worksurface is MDF and it appears plenty sturdy for anything I’m likely to clamp to it…
ASIDE: Seemingly, 79 is “my number” now. First, there was the ever-popular $79 Cenoz laser engraver, now this handy $79 MPR&P workstand… and quite irreversibly, now hurtling head-long toward my 79th birthday in just a few months. Oh, well… 
Back on topic… I found a piece of reflective tape and have confirmed that the 775 spindle I’m using tops out at ~20000 rpm.
Later.
