Plug lead guides for Rover V8

I have made replacement guides for the spark plug leads that attach to the rocker covers on Rover V8 engines.







The screw was seized and the original guides did not come off intact! 



A few measurements and design changes to suit 3D printing and the results work well.


The guides do need supports to print, mainly because of the large overhang for the counterbore.

I bought new machine screws. That was an exercise in working out historic imperial abstract naming conventions! The screws are 3/16"-24tpi x 5/8" long. That's not what you look for to try to buy them. They are called #10 UNC or #10-24. I will never understand the thinking process of naming something with another number to represent the size, instead of using the size!

Starter suitcase

Dean's life long dream is to built a hot rod from scratch. He's bought a 1970 Rover 3500 V8 engine, probably from a P6, along with a Borg-Warner model 35 auto gearbox. He needs this to be able to layout the chassis mounts and spacing.



I'll be helping out, mainly with the electrics. Today, I made up the wiring for the starter motor and we tried it out.


The good news is that the engine is not seized and by the feel of the airflow out of the spark plug holes, it appears to have some compression in all of the cylinders.



I'll add more electrics to the suitcase to enable testing as the build progresses.
