Mike, can you give us any info on what needs to be done if it isn't a proprietary secret type thing?
Back halves have to be cut off in bandsaw first off. Case have to be fixtured in the CNC to allow 360 degrees of rotation for the CAD. After that it is figuring out cuts and the best way to mount a backing plate. Original plates are 1/8" sheet aluminum with extremely random pattern sheet metal screws to secure the plates....really hit or miss. Russ Jr said it leaked pretty good ( or should it be bad) despite the 5 lbs of clear RTV used to seal them.

There are a lot of small details too.
The nice thing is all the cases will be exactly alike and future cases can be machined if needed. Case backs should seal well with just some 1194.
Building the engines themselves isn't difficult as it is just a crank. APE rebuilt the heads and did the cylinder work. Other logistical items are welding mounting brackets etc which we will discuss with Russ.
The original engines were a good start....these next generation will maintain the original look/form but be modern ( if that term can be applied

) and worthy of the precision rolling frame Russ has put together.
I struggled for months trying to figure out what to do (in regard to maintaining originaility, reliability etc etc etc) and I honestly think this is the best solution.
