Sailing Canoe Chapter 6: Morton's Oar

Step 10Workbench

Workbench
I moved my "workbench" out into the yard to make the dust storm.
I padded the clamp with some excelsior (http://www.thefreedictionary.com/excelsior that's really what it's called) put on my dust mask and safety goggles, and went to town. It worked pretty well.

It was pretty intense trying not to gouge the work or myself. The grinder had a good motor and did okay, but the gearbox got hot when I loaded it down. Bevel gears in a right-angle gearbox aren't very efficient for power transmission. I've hear that as much as 5% of your car's power is lost in the differential, which is also a right-angle gearbox. That lost power turns to heat.
This one probably needs re-packing with grease.

The blank wasn't thick enough for any errors. It ended up pretty straight and smooth.
I made a big dust storm and a thing that had the right sort of thickness taper to be a steering oar.
