    Might be a good idea. I'll watch the videos and see.

    Once you start the first video you might as well sit down with a bag of popcorn because you will watch all of them before you move I let them run a 1.5 speed because you can still understand what he is saying.
    A great universal bending machine
    Never try to tell me it can't be done

    Well no popcorn. But I did watch them all. The only shortcomings that I can see is the roller spacing of the ring rollers. The rest makes sense.

    Personally I'd fasten it down. I've worked with benders similar to this and it gets hard to counter your own force. Plus it seriously limits what you can do. If all your strength is devoted to bending it's a different story.

    You have to give him one thing though, to combine as many different aspects of bending metals into a single machine does take some thought.
    I agree on the distance for the rollers for the plate and ring roller however given that he utilized his existing frame as the basis for these limits where he would be able to locate hiss rollers. One way to counter this to a certain extent would be to make larger diameter dies for rolling rings and other things.
    Yes not having the machine mounted does pose issues but as we all know many of us can not dedicate an area solely for the purpose of any singular job function, meaning there has to be a trade off somewhere.
    I used to have a shop that had oilfield drill pipe collars embedded flush in the floor at various places allowing me to use the floor more or less in much the same way as you would a platen table for clamping pushing or pulling against. These had been placed there by a previous owner who had a body shop he used them for straightening vehicle frames. I used them for fabrication of large assemblies.
    Looking as his machine yes for my purposes I can spot a few things right off the bat which I would do differently should I be so inclined to construct such a machine, but I have the advantage of seeing an already completed machine with several singular purpose machines already incorporated into the design.
    And one thing is for certain finished does not mean completed there will be numerous dies and attachments he will need to make for it over time.

    I agree with you. Great machine. And easy to be the arm chair quarterback. Larger diameter dies would fix the only thing that I can find fault with. If I have the need for some serious bending I will consult those videos again for sure.
