The Parker Hanifin I have will not do schedule 40 stainless steel pipe so I got the JD32, I have a Greenlee powerpack that I will use to power the system so all and all it is a pretty cheap investment. It is a rugged bender though from the parts I have received so far. They are slightly behind on certain components due to their suppliers being behind on shipping to them. Only thing I can see is that you save $30 or $35 per die getting the 90, so if you're absolutely sure you'd never need it, I guess it would save a couple bucks.? For that little price difference, the 180 degree die seems like a no brainer.I just ordered the JD2 hydraulic bender. Given the location of the follow block, you can't get a second bend close enough to the first one to even come close to hitting the back of the die. I have a JD2 model 3, so pretty much the same geometry as your model 32, and I cannot envision a profile that you can bend on a 90 but not a 180.
More actual time planning, than actual machining. Not expensive, but requiring a lot of midstream redesigns as it progressed. Smoother, and less tendency to crush/mar the tubing.Īnyways.the build was a long drawn out process. I was surprised that they fit looser than I thought they would.Ī draw bender is better than the old style crush benders.
If you look at various websites, you can get the clearance sizes for different size/diameter plugs. The key is adjusting the plug so that it's in the right place as the tube bends. Really just an adjustable rod with a mandrel plug on the end of it. Parker offers a mandrel setup for use with its benchtop bender, you might want to look at it. I need to make a mandrel thingy for it, so that it will do thin wall tubing. It works well with thick wall tubing up to 1" diameter stainless or carbon. No slopping lube on the tubing to make it "flow" through the fixed die. I like the use of rollers instead of a solid follower die that clamps against the bending die. Not a direct copy, but the same principle.
