Well as I am recovering from my run in with the deer I am looking over my latest acquisition and am not really that happy about it. First question is could this be a correct front rim for my 66 Spitfire????
Second question is. Can rims be straightened ??? This rim is not as nice as I had hoped for. It has a few dings on the bead edges which I had expected but the worse one has actually been hit hard enough that the rim has flatten out to the point that it is obvious even on the spoke side of the rim. OK - so if it can be straightened then who does this and will it be too expensive to be worthwhile?
Wade; 42-5905 WM 2-19 is shown in Bacons BSA Twin book for 62-63 and 66-67. I have a 190mm wheel with 42/5905 stamped on the inside of the rim. On the outside is "BORRANI-WM 2-19 RECORD", nothing else. Do you have a part number in the inside?
Without frequent roadside repairs there is no fun in riding!
Thanks everyone. I cant find the serial # where yours is Gordo but I will look again when I give it a cleaning this weekend. I will also call Buchanans Sam. The only thing I have found on the web so far is a shop in Iowa who specialize in this so at least I have someone to compare prices http://alloywheelrepair-ia.com/?src=tp0&src=tc1a1262242602&dk=t The other thing I have found is someone selling a rim with similar markings saying it is for a Ducati 750 GT or sport. So it may not be right for my Spitfire but maybe I can sell or trade someone for the right one?? At least I have a bargaining chip possibly . I will keep searching and looking here for answers. Thanks Wade
Hope you are feeling better Wade, My 66 has Dunlops on it, but I have heard they could have Borrani rims also. Is it an illusion or are the spoke nipples cocked a bit in your photo? The one I noticed is under the RR in Borrani. If the rim has been replaced at some point, the drilling might be off a bit depending on the hub it was originally drilled for. I think it is probably the shadows on second glance.....
I didn't see this thread until late last night. I'll check out my front wheel for you. I know it's a Borrani but I don't know what's stamped on it for sure. It seems that a lot of the Spitfires had Borrani fronts and Dunlop rears. When I got my bike as a basket case someone else had started a restoration on it. By starting a restoration, I mean they had totally disassembled the bike, but they had gotten some powder coating done and the wheels had been rebuilt with SS spokes and polished by Buchanon's. They look very nice.
Never, never, never, never ever straighten out an alloy rim or even worse a cast alloy wheel. Bending them dose internal damage to the crystal microstructure that you can neither see nor measure ( without cutting the wheel and making microscope samples ). The result may be a sudden catastrophic failure of the rim. No one who has had this happen can tell you about it because no one has survived one. Wheels are heat treated to a T6 temper designation so should be full annealed prior to repair then annealed and rehardened after. Just because you can force it back into the correct shape dose not mean that it is either fixed nor fit for service. A lot of clowns tell me that they "fix" alloys but none of them can even tell me what a T6 temper in aluminium is
Hello lads, The different bikes have different wheel layout (spoke set offs). Due to the kind of wheel hub - drum brakes vs disc brakes and so on.
I got a classic Borrani WM2 19" disc braked wheel for my Commando basket case. Wanted to shape it up so bought new spokes, unmounted (unscrewed) the old ones, plugged in the new ones and had to be tidy with the set off (the '73 Commando has the hub way out to one side to make the wheel go centered in the fork). Knowing the set off data is enough to make a good wheel. To center it you need a jig to place the wheel in and it's best read a little about mounting the spokes (this forum has very good guidance on the theme).
So you have some options: 1. Do the job roughly by yourself and get a more skilled person truing it. 2. Do it all by yourself (a little bit at a time). 3. Let some other do it. 4. Get a new one alike (f.ex from Spanish Acront).
BUT some of it you can do yourself. Polishing f.ex. - After the spokes are removed there is plenty of room. At last you finish with a good wax (some work, but you have to polish these Boranis every once in a while - as with all other aluminium rims).
