Dec 20th - Update to "AoK announcement on a new Dual Carb intake for the USA flathead 6"
**** Development Update **** Behind the Scenes ***
Well as promised a little sneak peak behind the scenes on the development of the new Dual Carb AoK intake.
And just to give people an idea of where this process is going, I have also attached the finished AoK triple intake
that followed this exact same development process.
So since our last update, which to recap was the completion of the core. Unfortunately I dont have a picture of the dual intake core, so I will attached the core from the triple in a picture beside an original Eddy Edmunds Triple carb intake. The core, made of a special foam is put inside a finished mold and after the alunimum is poured in the mold, the casting is reheated and the core suddenly turns to powder and after it is blown out, you have the inside of your intake.
In any case, this is the pattern for the outter mold. Believe it or not, this is where the major work is. It is all created in wood and its something the "masters of the trade" never let people actually see. Those who do this stage are absolute artists and this is where the true magic happens in my mind.
You will notice the tab that will eventually act as a spot for truck and older cars that use linkeage attached to the outside of the intake, as well as the spot for a serial number. You may also notice the top of the carb base has tabs on both the inside and outside of the intake. Those can be used for linkage on either the inside or outside of the intake. With none of the current in production intakes offer this, it was a feature that Edmunds had, although they had 1 generation which had the tabs only on the outside and another only on the inside. For the AoK it can have either or left undrilled and not use this option.
Still to be finished at this stage, is the core and pattern for the water tube. It too will be an optional item where you can use it or leave it unused. Were having a bit of a discussion today as to its exact location as when Edmunds did include a water jacket and he didnt do it for all intakes, he never offered the otter tabs for truck or older car linkage. This is not a complex stage and should be done with another 30 hours of work which Tom says he is on track to finish before Christmas.
So images p1000073, 75, 76 are all the patterns from which the outter mold will be made from.
In the end, we will have a pattern to make the core for the inside of the intake, a pattern to make the core for the water tube and
finally a pattern for the outside of the intake.
Once you have those you use the core patterns to make foam cores. You need 1 intake foam core and 1 water tube foam core for every single intake we make. Then you set those cores inside the outter intake mold and pour it with alunimum. You let it cool, then reheat the intake to turn your cores to dust, as well as heat treat the actual alunimum. With those steps done, you have the raw intakes
ready to send for the machine shop.
