Joey, care to share your setup?
There is nowhere for a refrence point to start your bend, there is nowhere to measure (outside of the work piece its self), The dies are spaces so far apart, you need 4' of pipe/ tube to make anything, smaller and your SOL. You cant start a second bend from a different direction within the space of the dies on the rig, How do you measure the consumption of material when you make bends to account for your next bend? Oh, Whats your max bend angle? 75, 80*?... Mandrill FTW.
Perhaps I'm spoiled by good tools at work, Maybe I want a little more from the tool, but why mess around and try to make something work LIKE THIS when you can buy one that works right? Yes, I understand Spring compressor tools, pulling tools and basic home made tools. The difference, this tool matters. Unless all you need/ want is one angle in 5' of tube/ pipe.
Win me over (please), Show me how to copy a Featherbed frame with one.
