Shooting in the dark here, but

The tubing benders for EMT (electrical metal tubing) are sized so the diameter in the bending tool matches the diameter of the tubing. Bends show almost no deformation. A similar techinque might work for larger diameters?

I have been practicing my tube coping techniques that I have learned from you guys and things are proceeding along nicely.

Here is the big question - what techniques do you guys use to get nice right angle curves in your tubing projects. I have seen the pipe bender at HF and realize that it will squish the radius of the curve some - that is not a problem for my application - but I just wanted to see if you moss-backs (or would it be spatter-backs) have some wisdom to impart.

Thanks for all your help - I find myself cyber-slacking and checking the forum several times a day!

Hey Doc, I have used the bender from HB, I usaually make 2 bends to keep from kinking the tube(for tree stands) or you can get benders from Lowes, Home Depot etc. in the electrical section. You have to get the bender size specific. I have enclosed the one I have for 1/2 inch.

Congrats on finishing the class...now you BEGIN to learn...

Tubing and pipe are measured differently...tubes OD...Pipe ID. That said, it is possible to bend tubing in a pipe bender, but it is much better to use a tubing bender for tubing and a pipe bender for (you guessed it...) pipe.

Much was said on the old forum, complete with web links to see them. ( or was it here...senior moment...)

I forget who said what, but I think they'll chime in.
