SCOUT CYLINDER DECK CUTTING- BLUEPRINTING
Ironwigwam is now able to offer blue printing services for your sport scout engine. We have constructed a tooling plate that for establishing the correct timing of the 21 degree decks based on the location of the crank and the rear cam location. Our fixture was inspired by my father’s recollection of how Paul Giambinnio came to Daytona in 1946 and used a similar plate to inspect the timing of the William Kelly’s factory sponsored scout racer. Back then they had to file the cases to fit the template. We have come full circle here. We do the same on a Bridgeport milling machine to true the cylinder decks up to be square and in correct location to the rear cam which is very important when trying to be fast.
Remember most of these cycles were machined using WW2 machining capabilities on WW1 machines. Plus they have more than likely been abused or mismatched thru the years.
We fly cut the cylinder decks to remove minimal material to square them up and then take a skim bore in the cylinder spigots to true them up and put them in the correct location based on our fixture we have used trigonometry to locate the cylinder center line at the 4.875 deck height with a key way that we can find and locate from.
Labor for this feature is $100 and can only be performed on engines with the War path pinion race. We are looking into the possibility of creating a special crank pin to accept standard pinion races on our fixture and are awaiting to see if there is enough demand.
