Default Bender Build...

Not started yet, but over the next weeks weeks or so, I'll be building a hydraulic tube bender.

The good-old pipe bender has worked ok up until now, but I'd like something better, and fully automatic.

So, I'l be building a version of this one here, which people seem to have good luck with:

My goal is to get a air powered hydraulic ram and use that for the cylinder, as many have done on that thread.

Anyway, I'll post up when I've made some progress. Once its build, I'm thinking of making some dies myself, for some specialty applications.

At first, though, I'll buy at least one die, probably a 1.75" 6" CLR 240*

very cool

looking at the one you posted, (and its always hard to tell in photos) but having that single point to push from could spell trouble (green circle) the further it goes out in stroke. if there was a second location to push from it would help cylinder life (red arrow)

mine has about 7 or so notches to work from which i think is too many really. i only use 2 or three for 180's and most bends dont require that i move it at all.

also, a set of locking casters is a great thing since some pieces might hit your ceiling as your working (indoor outdoor option). it seems like im always moving mine and its way heavier than it looks.

I'm planning on making a wheeled base for it of some sort.

I believe people are getting about 95* of bend with one stroke of the ram, then you have to repin the die to go beyond that. Given that 95% of my bends will probably be 90* or less, I'm ok with that.

thats perfect for most applications.

i dont go much past 90 very often either, (at least on wheeln stuff) - plus its nice to get that much bend in one stroke, should be a nice set up.
