Bender problems

[Dave500]

Hi all! I've been given an old rothenberger pipe bender from my supervisor at work and it has started rippling the pipe and I was just wondering if there was a way of fixing this?
I've tried tightening the rollers and the formers and I have made sure that the guides are smooth.
If anyone has got any ideas on how to fix this it would be very appreciated.
Cheers, Dave

Dave , it could be the tube itself

Try putting a piece of hacksaw blade between the roller and the guide if it pulls cleanly get a new set of Benders.....regards Turnpin

 

[Dave500]

Cheers lads! Ill try that tomorrow thanks turnpin

Give them back to your supervisor and ask him to pull a bend without rippling the pipe. If he can't do it, tell him he owes you a set of new benders.

You may need a new guide.

 

[Jay The Plumber]

its often the bolt that joins the whole lot together needs tightening

 

[REDSAW]

throw it away and use an elbow

 

[Howsie]

Or a knee.

Make sure the rollers are tight but not too tight along with any other bolts, clean the rollers, formers and the bender part with wire wool, if it still ripples most likely cheap pipe or benders had it, if you've got some old copper that you've ripped out try bending that and see if it ripples

try lightly sanding the fixed guides,crap builds up on them over time and can cause issues,other than that bin it and get a manufactured old school hilmor from here Hand Pipe Bender 15/22mm BRITISH, compatible with Hilmor glm GREAT RESULTS | eBay

Thanks everyone for your replies. Ill try some of the things suggested this weekend but I think they may of had it.

If you're messing around with it, take the roller bolts right off and put some grease on them so the rollers... roll... instead of dragging. It makes it more pleasant to use (but I don't think it will solve your problem).

The Benditnow bender as suggested above is pretty good, I'd say better than modern Hilmor. I found my Benditnow hook was a bit rough and marked the pipe (I had to file it a bit) , but other than that, I've been pleased with it.

Yep

As a short term measure a bit of light oil or WD40 on the former and slide contact surfaces can help. It seems to happen when rather than the pipe "flowing" smoothly as it stretches one side and compresses the other, it repeatedly sticks and frees causing some ripples to form.
