While looking through the all the dealers sites for a cool looking inexpensive gas tank I became some what frustrated with what was available, and wouldn't tip off the local constabulary to the bikes true nature the second they saw a top tube gas tank.
Spun aluminum keg style style tanks look nice but cost $200.00 or more.
Saddle tanks from Whizzer or the regular pressed tanks just don't cut it for me looks wise.
While on the other forum I caught a thread about a guy that made a beautiful in frame tank out of tin for a Schwinn. It fit perfectly between the top tube and the two thinner cantilever tubes, a true work of the metal smiths art.
I'm the first to admit, I don't have ANYWHERE near this guys skills or equipment... but I can be pretty clever when it comes to improvising something cool looking, strong and that gets the job done.
A keg tank, rack mounted... Hmmmm
I'm sure we've all seen the V8 juice can gas tanks, they look OK, and are functional an the ones I've seen are very well made, but to me they still look like i'm bringing home a juice can from the store strapped to my rack.
I pondered what materials to make my tank from that were easily worked with (no welding involved) functional and yet still look cool...
While talking to a plumber friend of mine, he suggested a piece of copper water pipe and 2 end caps, we got stoked... we go out to his truck and he pulls out an 8" length of scrap 4" copper water pipe and 2, 4" end caps and Viola!
We had the main body of the tank, a quick trip to Home Depot for a double male brass garden hose connector, a brass cap with gasket for said connector, a 90 deg. 1/4" street elbow and one female 1/4" adapter to screw the street elbow into.
I took the gas valve from a regular kit tank and laid all the parts on the bench to dope out how we would put them all together to mount them.
A bottle of flux, a roll of silver solder, a can of map gas and 3 grades of emery cloth for polishing down the copper was purchased was at the same time.
Total cost for the hardware and consumables? $32.79
(the copper was free, donated by my good buddy and fellow M/Ber George the plumber, DUDE!!! thanks, good looking out!)
If you were to buy the copper it would have cost about $75 to $80 bucks more.
(it seems copper pipe and fittings that size are ridiculously expensive)
80.00 + 32.79=112.79... a bit stiff because of the high price of copper, but for something unique to your bike? and still half the price of a store bought tank...not bad at all.
Due to the thickness of the copper it was a little difficult to get it hot enough to accept the solder, we solved that problem by using two torches at the same time
It could easily be made from steel or aluminum if you don't mind a little welding for the cap and petcock bungs. since I don't have access to a welder...WE SWEAT IT!
A simple cradle mount would hold the tank to the rack by its 4 mounting strap holes.
We cut up a 4" copper straight fitting and flattened it out with a mallet and a 2 steel plates to create the mount, then i used my bench vise as a break and careful measuring to bend up the cradle mount.
(quite a bit of banging and cussing as well)
Ill use two copper perforated straps to hold it to the mount, and rubber washers underneath the mount to isolate it a bit from vibration.
First I sanded all the copper pieces to remove most of the manufacturing marks and make it easier to polish later after all the soldering is done and fit all the main parts together.
Then I started measuring the mocked up tank on the rack to discern the best placement for the mount, gas cap and fuel valve and marked them.
I decided on a center mount for the gas cap, and I chose to place the fuel valve through the open slot in the rack to protect it from strike or crash damage.
A quick few coats of clear gloss to protect it from tarnishing and the leather band to hide the mounting straps.
First I washed it out with soap and hot water, then a solution of baking soda and hot water to neutralize any flux left inside the tank, then blasted it dry with compressed air, then just to make sure the copper wont react with the fuel I coated the inside of the tank with sealer before final assembly, hey, if it works for nasty rusted old Harley gas tanks, why not mine?
I think it came out great, exactly what i was thinking of.
Please check the pics... maybe this will work for you. I hope you like it.
