« Part 1: The Drum Part 2 of My Home Made Thickness Sander series Part 3: The Table Adjustment Mechanism »

After building the drum, a test was in order. After all, if this part didn’t run true there was no sense in moving forward.
Using a piece of Corian, the motor and drum were clamped down in position. The motor is a 120v 1/3 HP motor salvaged out of our old furnace. The belt is the one from my table saw- a link belt replaced it.

With some anxiousness, power was applied. Holy Cow, It Worked!!

The pulley ratio is about 1:1.5- the drum being larger- so the speed of the drum is slightly more than 1000 RPMs.
I hear everyone talking about the “Nickel Test” so what the heck-

There is belt vibration but some of that should be eliminated when the motor is mounted properly. But the nickel stood on edge!!

Next, the table lifting mechanism. Talk about overkill!!

Does the 1/3 HP motor have enough power or does it get bogged down on hard wide stock?

BTW: Love shop built machines. Great job.

Karson, CJ- Thanks!

Randy- Haven’t really tested it on anything wide yet but the 2 rolling pin strips don’t affect it at all.
