I haveĀ  the cheaper version of that saw for cutting the wife's glasswork and anything else I want to do.
It's the 7", with the repurposed angle grinder for the motor. The sliding table was plastic and had a warp so I just kept the linear bearings and made a new table from 1/4" Al plate.
A very useful tool to have!

Neighbor (a hoarder) died from a stroke a few years back and my other neighbor bought the place.
i helped him clear out the junk and got ahold of a few goodies, (2x4 of ebony, etc). Among the treasures wad some lapidary equipment. Haven't set it up yet (I'm a rock hound) but there is potential. One item is an old rock saw, blade spin in a bath of oil (mineral oil typically) and has the counterweight drive for feeding. Someday I'll get it set up and slab off some agates for a project.
