pics or it never happened! that is a cute tea pot... funny funny.
Is anybody interested in the style of tank that is on my bike?
I believe they hold about 3/4 of a gallon.
even better if they come with a cap
$$$ ?
Here's a pic of my tank I had fab'd for my 41 Schwinn straight bar frame. I really don't care for the stock tanks that come with the engine kits. A local, custom motorcycle builder made it for me. It wasn't cheap, but everyone digs the lines.
where can you get them?Yes, they come with a gas cap. They also come with plastic line out but no petcock. The price I paid for one is $75.

Here's a trick for making a fiberglass tank...
If you make a plug or model of a tank out of styrofoam
(the packing kind in computers or furniture)
Using a hacksaw, "cheesegrater" wood file or even 36/60 grit sandpaper.
make it like 3/16" smaller all around, the fiberglass will bulk it up.
Using epoxy resin and a light fiberglass, 2 layers should do it.
it will be a little rough but it should sand smooth,
later on a little body filler can fill in any bad spots.
Basically you just made a miniature surfboard.
Anyway,
figure out the placement for the inlets and outlets.
This might sound like the tough part but its not too difficult just time consuming.
Use a hole saw/drill bit/file whatever and make the holes.
You can use plastic from a soda bottle and tape a cylinder for the cap,
than fiberglass around it and remove the plastic.
*you can fg inside or outside of the plastic "mold"
The cool thing about epoxy is it will bond to aluminum as well,
so if you have an aluminum cap/inlet/outlet than just fiberglass it on there.
(I guess if you were thinking ahead, it could have been fg'd during the first coating process.)
Anyway a fg outlet is easy too.
Find a bolt that is the same thread as the stock valve,
wax it with some candle wax or car wax,
making sure not to plug threads though, just to slick it up,
and screw it into the hole that you put in your tank.
Mix up a little epoxy and add some chopped fiberglass powder, or flour even,
and make a thicker paste, coat it around the threads.
Than fiberglass a little bit around that to give it some strength.
After it cures,
unscrew the bolt and you will be able to screw in the fuel valve.
Now that you have a tank with an inlet and outlet,
pour acetone into the filler and it will immediately dissolve the styrofoam.
Just repeat that process until its totally empty,
plug up the ends and shake it up to make sure its all out,
if you throw in some marbles, ballbearings or clean rocks it will scour the inside really good.
(make sure to not breathe in the fumes it must be toxic)
After paint,
i'd throw some gas in there and shake it up too,
and inspect the gas for any contaminants.
Anyway that's a kinda easy way to make a one-off fiberglass tank.

Silverbear-
First off, EPOXY ONLY, vinylester or polyester resin will disintegrate styrofoam...
The first steps in the fiberglassing is called a "hot-coat",
where the styrofoam is coated in epoxy resin, sealing it up, using no actual fiberglass.
Just continually sand and coat it until it is smoother and smoother. (with no fg cloth)
At this point it would be a good step to add your nuts WITH BOLTS for your frame clamps.
(dig into the styrofoam before so there's a little sealed divot)
than they can be flush during the actual fiberglass cloth layup.
As to the styrofoam,
white styrofoam I know works and dissolves cleanly.
Practice on other types of styrofoam with the acetone to how it reacts.
Surfboards use the "bigballed" styrofoam not really anything too special.
On something small, 5-min epoxy used in little dabs should be fine.
Hot glue gun or contact cement might work,
but the least amount possible as it mightr melt into the tank and be hard to clean out.
I've actually never made a gas tank but have made a number of oil tanks and other random hollow bulbs,
and never thought of pictures.
but i know it works, just is kind of a dirty job, lotsa sanding ya know.
I'm in the process of making a fg tank right now, but its not the same method,
it might work out easier for some.
It'll be posted soon.

here's a sneak peak, silverbear.
It's for that shelby project.

actually check out this website. Website go to the parts page and seach until you get to gas tanks. They go from about 40.00 to over a bill. They ship. The less expensive ones obviously need some work.
