BIG BOY PEPPERELL 23 T/R DIESEL

This project was brought into being as an addon to our pepperell 23 team race diesel replica engine project, and is the concept prototype for a limited production run of a 24cc version of those production replica's.

As with all our machined from solid concept engines it will start from here.........

A block of 4" square x 6" long 6061 T6 ally

End of the first machining operation carried out on the lathe looks like this....

Second machining operation completed, also on the lathe, leaves us here....

Custom built engines require a vast amount of additional purpose made tooling to be manufactured, which consumes a huge amount of time, which contributes to the often high final price.

Photo below shows us ready to go to the milling machine for the first milling operation.
