I just happened upon this:
Tommy Hatch came 3rd in the senior TT on a Scott on this year. The last time a Scott took such a high position in that event.
Tommy wasn’t riding the only Scott in this event and a couple of Scotts can be seen waiting for their turn to start.
I already posted a picture of an iron barrel my father, Roger, has been machining up from one of his castings but he’s sent me some more pictures as he’s almost finished.
Pics depict a newly manufactured iron block showing inlet tract arrangement where it must be noted that as the “Spectacles” portion of the crankcase will be removed, then this forms the upper ceiling of an enhanced inlet tract.
Note the two 10mm counter bores which are used to enable accurate poisoning on holding fixtures during the metal cutting processes and by using ring dowels (Sleeves) to accurately position the cylinder head which also has such features.
Ports timings are more advanced than standard DPY blocks, but less than the aluminium competition blocks I make to special order which still give much improved torque at low to medium revs.
Dies and piston blanks to make 500cc pistons are currently in manufacture as are another batch of cranks comprising 15 sets of standard long stroke cranks. 5 sets of standard long stroke cranks to be fitted with Tungsten weighting slugs, and finally 5 sets of a special heavy duty crank variant for use with ball bearing main bearings and incorporating heavy metal weighting slugs. These can be used in standard cases after appropriate modification or in the Moss high duty large inlet competition crankcases.
If you are interested then contact him at Moss Engineering.
This is great. I was sent this picture of Barry Scully and his 500cc Scott racer.
You can see the amount of work that went on this bike… Is it still around?
My dad, Roger, has been working to make sure that as many new engine components are available as possible; pistons, heads, crankcases, cranks, transfer port covers are all available as new components. One of the items that he makes for the racing and sports engines that he produces for people is the cylinder block, normally in aluminium with hard chromed bores.
He’s got iron block castings but he’s not machined one up for years, but he was today and sent me a picture.
FNT
In the last days I’ve been contacted by the new owners of both the Silk Scott prototype and ‘FNT’.
FNT went through a period of development which resulted in the fitment of one of the early Silk engines, Georges own, Scott based design. In the intervening years it was forced into boxes for a little while, but is now in deepest Wales and being rebuilt for use on the road. The owner confided that he had some sense of guilt about that, but the various racing focused parts will be retained for possible future use.
The Silk Scott prototype
It appears that the Silk Scott prototype machine is in Spain now and seems to have remained largely unchanged. The owners have a collection of all manner of period literature and photographs which document its previous life and the Manx GP race in the hands of Stuart Hicken, who is now part of the management of Mallory park.
The machine is for sale on ‘Car and Classic’ for £25,000. I’m not running a classified section, but I thought it was very interesting to see all the photos and documentation that they sent me and I thought that others may enjoy it too.
As well as the images, the owner also sent a number of scans of period reports of the Silk Scott’s TT adventure, as well as other relevant information.
