Back in the day I inherited what must have been THE worst gigged Hammond C in existance. It was held up with 2x4s and some of the biggest nails I'd ever seen. Once I got it up and running, which was a labor of love, and since there was no internet I had to find the schematics at the Library of Congress, I proceeded with a chop that utilized a few 2x2s that braced a set of carry all's onto the bare chassis. It was a beast to haul around but sounded fantastic. She still lives in my basement but will never be gigged again.
