Norton Big End Assembly and Parts
I have recently expanded the range of Norton Big End parts I can supply. I can now offer both 500cc and 350cc Norton International BigEnds, as well as Racing International (30M), SOHC, early DOHC and Late DOHC Manx BigEnd assemblies.

Finally, I have just had commisioned a batch of the correct 30M and Manx large Hexagonal nuts, as fitted to all racing crankshaft assemblies (SOHC and DOHC), before Norton swapped to using castellated nuts with their shortstroke engines. These Manx nuts have the same profile as International hexagonal nuts, but are wider, so they spread load over a wider area. Contact me if you need more detail or are not sure what Bigend your engine requires

Inter engine plates

Unfinished Version
This is where I am up to at the moment - castings machined but not chromed. Lever pressed, but final bend not put it in yet

Latest Version
This is the revised shape I am now modelling. Although there were a variety of shapes used for comp levers, this delicate pattern seems common on racing Norton's

Racing Clutch and Brake Levers
Long racing levers (as fitted to SOHC Nortons, Velo KTT's etc) have not been available for many years. As you can see from the photographs above, I am in the process of manufacturing a batch of these levers.
Latest Update October 2010: Apologies these are not complete yet, but they are getting closer. I have decded to change the blade from stainless (shown in the photograph) to chromed steel, as stainless was proving too difficlut to bend accurately and was difficult to polish. I have also taken the opportunity to revise the shape to more delicate looking pattern (see lower left photo), which I have seen more commonly fitted to racing Norton motorcycles in the 1930's-40's..
Price TBC. Expected Winter 2009

New Castings in Progress
As you can see from the photographs above, I am in the process of manufacturing more of the main SOHC Norton engine castings. All of the above have had trial castings in magnesium, and are now in the process of initial machining. As you will appreciate, ensuring the finished product is correct in detail and of the required high quality is a lengthy (and costly!) process. With this in mind I would not expect to have anything ready for sale until Winter 2009, but watch this space, and let me know if you are interested and require more details.

Work So Far
As you can see from the photos above, work is now progressing well. The inner timing cover in the lower right corner is an original SOHC magnesium Manx version. The item on the lower left is a 'part machined' new one. As you can see they are effectively identical in construction (although obviously my replica item has not yet been completed). Both outer timing covers in the photographs are my replica versions and are again - identical to originals. the ribbed version on the top right is the extremely rare 'Works' version fitted in 1936/37, allowing for a rev clock to be fitted. I have made these for those people who prefer the earlier 'ribbed' type cover.
Latest Update October 2010: I have now had a second casting of the timing case and cover made, to incorporate minor amendments and this has now been finsh machined and fitted. From this I am now in progress of having a production bast cast. I am hoping that these should be finish machined and available for Winter 2009
