Finally an impressive produced bend after watching many videos great job.......I set and operate a few different mandrel benders stainless and aluminized 1 3/4 to 3'' and have noticed most have way too much pressure set on all tooling and use too much y boost or not enough free movement of the pressure die slide or follower or lead lag the program depending on the machine brand so they are forcing the pipe to bend instead of forming you can see the clamp slip and inner wrinkles in so many videos showing their apparent quality bends but the over pressured tooling is easy to see in their results
