Anvil tube bender

Hi. I understand that Anvil is permanently closed. Have been looking on videos on the Anvil tube bender and it is just what i need for mye Reynolds 631 tubes. Does anyone have one for sale? Or if not, is it possible to make some measurements of the parts so that i can produce one myself? That is if the production of that bender is also discontinued.

Yes. I know and that looks nice for sure but i think the Anvil is more suitable for my need. Seems to me that it is easier to make a smooth radius/curve along the length of the TT because the die is much longer. I might be wrong though.

I'm not sure I believe you can make a long bend in a butted top tube with a bender like that. My impression is that people are mostly using that style of bender for short bends in seat tubes for tire clearance. And obviously bends in smaller diameter tubes.

You may want to contact Adam Sklar and ask what he does. My sense is that a straight gauge tube running through 3 rollers would be more suitable to large radius curves for a top tube.

You may be right. A traditional radius bender would probably be better.

Anyone that is making curved top tube frames with a constant curve is using a tubing roller. The most common one one is this Harbor Freight roller https://www.harborfreight.com/tubing...psugg_q=roller with dies from Swag Offroad https://www.swagoffroad.com/SWAG-Tub...ries_c_54.html

Rolling a tube requires the tube to have sacrificial material on each end, because you cannot roll the tube all of the way through the full length of the tube. You will have a flat section on each end of the tube that has to be cut off, so a long straight gauge tube is what is generally used.
