Yes actually I used JB on the gasifier fan to patch a hole and some on the VW muffler to get it just right.

Take pride in the tools you were given.
Take joy in the tools you earned.
Stay curious KID.

I got a 2.5kw generator head from ebay for $100 (including shipping)
Then I got a 6hp engine from Harbor Freight (also $100 on sale)

I clamped down the engine to a big trailer so it couldn't vibrate much while it ran.
I marked 3/4" from the end of the shaft with a sharpie. Then I marked 1/8" circle
from the 5/16" tapped hole in the end of the shaft.
I started the engine at low idle then I used an angle grinder with sandpaper
flap disk to shave the shaft conical at the end grinding down to the lines.
I bolted the genhead on to the motor and started it up. It ran perfectly. It has now been running daily for 3 months.
