Italianiron/BritIron Classics Additional Aluminum Tank Offerings

Posted by Scot Wilson on

At Italianiron/BritIron Classics, it has always been our approach to offer higher quality products rather than what is cheapest. As a result of this business philosophy, we are very proud to source products where we are assured of their quality. Such is the case with regard to our aluminum fuel tanks for the "deep sump" TT 2, TT 1 racers and the "shallow-sump" TT 900 racers where we use modern Ducati engines. In addition to our Ducati and TT Racer fuel tanks, we are now offering a nice selection of high quality aluminum Norton Commando fuel tanks. The purpose of this blog post is to discuss the quality of our fuel tanks and to discuss how they are made. We are also very committed to the sport of Vintage Motorcycle Racing that also drives our need to offer better built and higher quality items that can best handle the stresses of the racetrack. Shown below is the new aluminum "shallow sump" TT 900 tank that I am using on my "blue on red" TT 1 with 750 cc race-prepped engine on the left and the previous fuel tank version of the TT 2 styled tank that is mounted on my "silver on red" TT 1000 with Monster S2R engine. Both of these hand-made aluminum fuel tanks maintain very smooth, rounded shapes that seem also to "flow" consistently and evenly along the frame rails of both racers.

At Italianiron/BritIron Classics, we enjoy working with craftsmen who manufacture our aluminum fuel tanks by Hand using a mallet, sandbag and an English Wheel. Apart from the raised "eyebrow" on the top of this "shallow sump" TT 900 fuel tank that is pressed, the rest of the fuel tank is made with human skill. To quote Andy Molnar, "all that is used to turn them from a flat sheet of aluminum is skill, experience & the rack of the eye!" All of these aluminum fuel tanks after being formed, are Gas-Welded which is arguably an art form in itself. This is a qualitative advantage to the production of our fuel tanks that we have determined over time. On the internet there are many articles on the topic of the numerous advantages of Gas Welding. I am currently quoting a section of an article written by Kent from TM Technology, "TIG vs Torch". Obviously what is best, TIG or Torch is based upon the project undertaken. However, "if you find yourself working on metal that needs to be bent, rolled, hammered or shaped in any way, then you will really appreciate the strength you get from gas welding as you can work the heck out of the metal, something that you cannot do with your TIG welds which can crack, break or leak". Cracking, breaking or leaking are obviously unsuccessful results when using an aluminum fuel tank on a street or a racing motorcycle!! 

As anyone who has worked with aluminum knows, as soon as you touch a thin piece of aluminum with a torch, it instantly distorts like a crinkle potato chip or crisp! TIG welding aluminum often leads to a Heat Affected Zone (HAZ) next to the weld which often leads to premature failures. I discussed in a previous blog post about the "real world" experience that I had as a result of a premature aluminum failure of a TIG welded "Imola" fuel tank in the 14 June 20 blog post (link listed below). It was so surprising to me that this failure happened to this newly purchased aluminum fuel tank for my 1974 Ducati 750 ss and on the first race!! However, this aluminum Imola fuel tank cracked at the front frame mount as I was pulling into the pit garage after the race. What a mess was created when all of the residual fuel out of this large capacity fuel tank flowed down from the front of the tank and all over the floor. I was lucky that the break had not taken place during that BOTT race at the Mid-Ohio race track as there could have been some real fireworks!! Shown below is a special photo of Malcolme Tunstall, professional racer, mentor, and friend with me and my 750 ss racer with aluminum Imola fuel tank at the AHRMA (American Historical Racing Motorcycle Association) races at the Mid-Ohio racetrack when Vintage Days was simultaneously taking place. This photo was taken on Friday during practice sessions and before the cracks occurred. To this day, the Mid-Ohio racetrack remains one of my favorite US tracks as it is very reminiscent of UK & European racetracks that "flow" versus our many "point and shoot" US racetracks.

There are many shops that continue to manufacture and to offer aluminum fuel tanks using TIG welding. However, we do not. As such, it is my intention to state our position that we believe that due to the properties of aluminum, that Gas Welding is a superior welding technique for that medium and to assure the quality manufacture of our aluminum Ducati and Norton fuel tanks. Kent continues in his article that "On aluminum from .032"(.081 cm) to 3/16" (.476 cm) the torch wins on penetration, and the TIG has to weld both sides, or it needs a constant back-purge of inert gas during the welding operation. Distortion is equal or slightly better with the torch. The torch wins 'flat-out' on speed and leak resistance on tanks. The TIG has inherently weld-density issues because it boils the aluminum inside the weld bead, leaving more leaks on aluminum tanks." This is our experience as well and why we believe that Gas Welding combined with the process of Annealing, produces a superior product. We offer, in our opinion, a more reliable, safer, and a more qualitative product in our portfolio of aluminum Ducati, Norton & Seeley fuel tanks. The first of our new Norton Commando portfolio is shown below:
