HELP 10 inch sbp rear drums or modifications to front drums

I was going to cut the single "snow lip" off some front 10" SBP drums I have (easy to get) to use on the rear, as others have. Note: some have two lips so 2x the work. My plan was to bolt the drum outward on my rear axle, run the car in "R" so it spins slow and cut using a hacksaw. The spinning helps make a square cut. "Should Work" - they'll put that on my headstone. No need now since I lucked across some good 10" SBP rear drums at a local show and they guy didn't rape me ($40/pr I recall).

You can fix these cars cheap like me. Just be patient and not too quick to write a big check to companies with yellow or red products.
