WOOD magazine review

Solid cast-iron table, good dust collection

Review Summary

High points: Cast-iron table with a 3/4" miter slot and cast-iron platen. Table stops at 90°and 45°. Has holes for bench mounting. Manual disc brake stops disc quickly. Dust collection is good with a shop vacuum attached. Low points: Its 1/2-hp motor created the least power among the test group of six sanders, letting us stop the disc more easily that we'd expect. The miter gauge is unremarkable with no positive angle stops. Unreliable table-tilt scale.
It takes some time to remove worn abrasive discs from the cast-iron platen. More points: The table tilts on a rack and pinion gear, but the detents for common angles are so slight that we had a hard time telling when they engaged.

A blend of beefy performance and one cheezy part

Review Summary

This is a great sander. The platen is nice and flat and it has plenty of power to not bog down when sanding even very aggressively with big stock up against the wheel. But I do have a couple of niggles.... My first niggle is the plastic tab at the top of/behind the spinning wheel. What it's supposed to do is let you apply the breaks to the wheel when it's spinning down after the power's been turned off.
It levers a friction pad up against the back surface of the wheel and eliminates what would be a 1+ minute long spindown when shut off. In reality it's a flimsy plastic paddle that's going to break after you owned the thing a week. Or maybe that's just me. Breaking operations are still possible, but you'll have to reach behind and hold the break button manually. Same net effect, a little less elegant. Even so, they should have made the paddle out of metal. My second niggle is that you have to remove the table and remove the lower dust shroud in order to change paper. It's just not possible to do with either piece attached. It'll add a couple of minutes to the operation. Dust control is actually pretty good. When I spin the sander up it partially inflates my DC system that's... oh, about ten feet's worth of 4" PVC tubing away and when the DC system isn't even turned on yet. So yes, it exhales pretty efficiently. Do watch out for ungrounded outlet sources and don't add three-prong to two-prong adapters. It genuinely needs the grounding plug attached, as I found when was forced to use it on a remote install at the client's house, where a two prong outlet was the only thing available. I got a mild tingle when touching this tool and another that was on a grounded source. The electrically minded among you will say 'no fooling', I'm sure. But it is worth noting. Overall it's a very stalwart tool in my sanding arsenal.
