Sometimes I'm dumbstruck, how a creator feels his baby is SO exclusive, censorship is called for. Also unsure what a x-length video would reveal the lead picture doesn't. Diamond laps were revolutionary; post-advent of carbide tooling.
Not since.
Fractional hp motor, right angle reduction gear, inclinable table, chintzy frame, original appliance style wiring; yet no rubber feet, miter gauge, or wet well, splash guard over wheel periphery, fluid drip, possibly not reversible (all BIG considerations regarding diamond discs versus RH & LH cutters), accessible On-Off switch.
I really doubt the intent restricted to hone hand flaking scrapers.
