This is the third installment of an ongoing series detailing Margie Siegal’s restoration of a 1973 Harley-Davidson 350 Sprint. You can read the Part 1 here.

I looked at the nuts holding the Aermacchi head down. They looked back at me. The two on the right side were recessed into little caves in the fins. There was no way a normal wrench was going to fit here, let alone a socket wrench.

I re-read the service manual. It said to take the four nuts off, and then the head was supposed to slide right off the head bolts, unimpeded by a head gasket. It also said that you needed a “thin bladed wrench” to get the right side nuts off. Off to find the right wrench. It doesn’t exist. Next step: MAKE the right wrench by grinding down an existing wrench to fit. This will be A Learning Experience. I do have a grinder, but have never used it.
