Well the cold weather has dried up all the outside honey-do's so onto my long awaited project but i need some help. a while ago in the neet stuff there was a sporty frame with plans...cant find it. :think: anyone happen to retain this that could pass it along to me? anndddddd i have come across a scad of stainless 1.5" tubing but its only .065 wall.....any one have specs on whether or not this particular wall thickness would be suitable for my build? stainless for one is a concern....but wall thickness is the real question i guess. will send pics as the come.

Gary has a section on "tubing" on this site.

065 is a bit too thin. some stainless grades welds better than others and some are not even recommended for welding applications. Other than that I won't even pretend to know the ins/outs about that material (there's just too much to it), other than to say be careful and 065 is too thin, in general.

Free is good, but trade it or use it for something else.
My 2 cents worth...

Below are the two most commonly used tubings for frame fabrication. With a minimum of 0.120" wall thickness. Although bike frames have been built with all types of materials, including stainless, aluminum and chrome moly,(and I'm sure hrew and pipe!) you should stick with the norm, especially if this is your first build.
ASTM A-513 (CERW-DOM) Carbon and alloy steel mechanical tube manufactured by cold forming and electric resistance welding of cold rolled strip.

A-513, Type 2 CREW.Type 2, as-welded CREW (Cold Rolled Electric Weld) tube. CREW is usually supplied in 1010 grade.

A-513, Type 5, DOM.Type 5, welded and drawn-over- mandrel (DOM) tube. DOM is usually supplied in 1020 or 1026 grade.

By the way the .065 stainless is not suitable. Buy tubing from a reputable supplier. Don't use something a bud has laying around unless you are sure what it is.
I am sure this is covered on the main site and Gary's CD's.
Hope this helps, Jim

I would imagine the frame dimentions haven't changed a whole lot over the years themselves probably just the motor mounts due to the different engines build the frame to the evo spec leaving the motormounts off put it in a rolling chassis prop up the motor with the chain or belt to the rear wheel and build the mounts to fit the motor as long as the belt is strait to the rear wheel and the rear is strait to the front everything else is pretty much up to your eye shouldn't make a difference if its to evo spec or pan unless your trying to be true to oem just a thought :think:

I have seen buells and sporties in big twin frames.
