Cutting roof sheet with wire - GIF

[Frank S]

I ended up buying a guillotine type sheer with the dies/blades of the profile of metal that I used....but that had its own issues.

Did yours have a good clamp down for the sheet? I bought one that didn't have a good clamp. After I made a full profile clamp for it and converted it to hydraulic instead of manual it became a pleasure to cut dozens of sheets per day. We had it mounted on the rear of a trailer.
