There, I fixed it

When I bought my motorcycle, it came with awesome aluminium side boxes. The one on the left had a small hole that the previous owner had patched with jbweld, and it looked OK. But, I've had the bike for 7 years, and dropped it a few times, and it stopped keeping water out.
So, I bought a bottle of pure Argon for my mig welder, and a spool of aluminium wire and "there, I fixed it."
As it was

After grinding all of the jbweld and paint away from the damaged area.

After filling in the holes and re-shaping it with a flap disc sander.

Add a light to a weehoo

I made a bracket to mount a cygolight rear light onto a weehoo.
It was fairly easy. It's just a 5/8" by ~ 4 inch piece of aluminium with 4 holes drilled, two for the reflector and two for the light mount.

A new handwheel pulley for a pfaff 145 sewing machine

We bought a used industrial sewing machine:

and it was going way faster than either my wife or I could control.
The cheapest solution seemed to be to increase the pulley size on the sewing machine side, since the motor pulley was just 1.5". But, the machine pulley wasn't a standard buy it from Grainger thing:
It's a bit hard to see, but it's recessed to fit tight up to the handwheel and held on with a nut, not with a key and keyway.
My solution was to turn a new one out of maple.
It seems to have worked really well. I've sewn with it 3 or 4 times now.
