Title: Tubing bender
Post by: Joe d on March 27, 2010, 01:01:06 AM

Hi

I need a tubing bender for the exhaust, fuel, and coolant pipes on the Snow tandem that I'm building, so I got busy and made one according to the plans drawn up by George Britnell.

Started by turning some drill rod to the diameter of the tube, (four times, as I've got four different sizes of tubing to deal with) then used a ball turning device to form the radius on the end of the pieces, then to the mill to remove half of the material

hardened, and a lick on the grinder, and then into a purpose-built tool holder, and here's one cutting a forming die

Here's all the bits assembled and ready to go

And here's the set of dies, the bender, and a test piece

This thing works a treat, thanks George! Great design work. :thumbup:

No more excuses, will be getting back to the Snow now....

Cheers, Joe

That is a great looking set of dies and tube bender setup. I'm sure that George will be impressed how you followed his design. I am sure that you now have most of the sizes covered but if another size is needed it will not take you long to make a new size. :ddb: :ddb:

Cheers  :beer:

Don:  Only made the 4 sizes that I need immediately, but certainly can whip up any others pretty quickly as required.

David:  I've got nothing against quick bodges....  sure enough make scads of them myself (usually some really questionable work-holding thingymabob for the mill or the rotary table... mostly they work out, once in a while I get to make another piece as well as another bodged up work holder!)

Bernd:  Thanks.  Off topic: aren't you supposed to be building a kitchen?  (If you toss some of that cherry in the St Lawrence, I could fish it out when it floats by Montreal...... I'd happily send you some more newspaper in return :) )

Thanks Dean,

Joe

Thank you for teaching me a useful technique ... especially making one's own forming tool.
Inspiring.

Best wishes.

You're welcome, most of what I know about this game I've learned from various internet fora, I've found lots of people are willing to share their knowledge. (And a damned good thing that is! :beer: :beer: :beer:)

Cheers, Joe
