Purchased from a fellow OWWMer across the Mississippi in Iowa, this Master disc sander was one crusty critter, but was mostly complete.

The Model B of this machine "is for shops where a house dust collection system is available. The house suction system is attached directly to the four-inch exhaust tube which is standard equipment in the Model B series," according to 1944 Kindt-Collins Catalog M. These sanders were available in three different sizes, with 18-, 20-, or 24-inch disks, and with three different dust collection options each.

When received, the machine had two separate flexible conduits attached for supplying power. While odd, I thought little of it until I had opportunity to rebuild the motor and test its function after. Upon applying power, the motor started and ran so smoooooth--too smooth, in fact. It turns out that that the motor was wired for three phase, 440 volt operation, and I had supplied three phase, 230 volt. The motor would run, but would have no real power once loaded.

After diagramming the wiring, I cannot help but think that a previous owner had run two separate 220 volt feeds to the machine in order to power it. It only took a few minutes to re-wire the motor for 220 volt operation, and it functions as expected.

The paint color was matched to the circle of undamaged paint under the badge on the front door by my local Sherwin-Williams store, and is their Industrial Enamel HS paint. The paint was applied using a 3M Accuspray One gun, which uses a disposable spray head/tip/nozzle, as well as their PPS system. This is my first real foray with this spray gun, and I can say that I am quite pleased with it. The Sata RP guns are still my go-to guns, but this has the advantage of very easy clean-up.

The badge was hand-painted with One-Shot pin-striping enamel, using a magnifying lamp and my finest liner brush. It's not perfect, but the image in photo is just about life-size, so I think that it will do.

The mobile base was welded up by my son, John, also a member here and OWWM.

A transformer has been added to the machine so that common 120 volt light bulbs can be used, instead of sourcing 220 volt bulbs. This added to the wiring challenges, as did moving the reversing switch to the inside of the machine--the difficulty being a relatively confined space, and a lot going on.

All-in-all, this machine has turned out really well. I will continue to be on the lookout for the disc guard/dust deflector that mounts to the left and top of the machine, as well as an OEM Master core print/circle sanding gauge.
