Elaborate and outstanding device. I made a simple version of this a few years ago. Often sits on the mother work bench. Brings things closer to these old eyes. Dog holes can and do often hold a magnifying lighted viewer. 2 layers of MDF with an oak edging and legs. No built in vise but do have a clamp on one. Usually just use clamps across the width.
LBD, like yours a lot. Nicely done. More elaborate than mine.
That is handy 987 and seems like a hybrid between this and my mini workbench.
This mimi is designed for a worktop in my office while the other is designed for the workshop to bring work into the focal distance of my glasses without stooping. If I made another of "the others" (like yours), I'd still use the MFT style doghole layout and mount a Stanley vise (as above) instead of the expensive H & T Gordon.
If your first cut is too short... Take the second cut from the longer end... LBD
Biggest problem with my mini bench top bench is where to store it between uses. The legs do come off with two bolts each and then laid flat against he underside and rebolted using the holes in the bottom cross pieces of the legs. Never used that feature.
I am past big sized projects so mIne has a permanent role on my bench. In fact I have a MFT style bench on top of my main workbench, If I need to do larger work, I now do it on my centipede or tablesaw with the fence removed. just gotta watch the spilled vino on the TS, as vino is a great source of rust.
