Roadrunner SWB

[Paul Milner]

Does anyone know what the wall thickness of the main tube and rear stays is? I've got some 3"x.160"
aluminum tubing/pipe at work that I want to use for a homebuilt but I think that is a little
overkill. Paul Milner

Paul, A 3"x.160 aluminum tube is more than a "little" overkill. My Bacchetta Corsa clone uses a
2-1/4" aluminum tube with a .065 wall. A three foot section of the tube I`m using weighs 1.57 lbs.
A three foot section of 3"x.160 aluminum tube would weigh 5.03 lbs. What is your weight, or the
weight of the person who will be riding your homebuilt? Are you heat treating the frame if
aluminum is used?

Hey don't discourage him, I am dying to see this 160 inch long SWB, especially want to see it
do turns LOL

Hi Josh, Perhaps I didn't give th tubing dimensions correctly. The diameter is 3" and the wall
thickness is .160". I hope I can find a heat treatment oven here in Albuquerque. If not, I'll build
a simple one and stay close by to adjust the heat as necessary. Paul

Hi Don, The guy who will be riding the bike is 6'-5" and around 300 lbs. We call him 'Tiny'. Paul

Just clean the monitor - so you won't expect the random dots everywhere. ;-)

Pardon me if I'm not treating the language with proper respect, but how do you learn to write
english if not by writing english? Jeg kunne jo også bare slå over i dansk, så jeg var lidt mere på
hjemmebane.

Med højagtelse, Torben

Torben First time the dimensions were given it read 3" x. 160"=3 inches by 160 inches (the decimel
point was present, but not located where it should have been) re: 3" x. 160" should have been 3" x
.160"= X (space) dot, not Xdot (space)

Paul, Forget about trying to heat treat aluminum in an oven....it has to be solution heat treated,
where the metal is brought almost to the point of melting. I think you would be better off building
with chromoly...
