The original.








Home made "replica". I think he lost the only photo of the original and did it frem memory after a few too many beers.

Also not fun when members antagonize others here. My $.02.


Random billet 5.0L 911 case:

Just a matter of the stepover vs. diameter of the ball end mill being used for machining. Cutting down the stepover would smooth it out considerably, albeit at the cost of increased machine time. In the areas left kind of "rough" that I'm seeing, it really doesn't matter anyway. Finish the mating surfaces and bearing cradles, and it's all good.

Tommy Olsen of ITG Racing has been mesmerizing us over on the S Registry with his machined from billet 2.0 liter cases for historic racing. Here is an example of the same cases, essentially, with much closer stepover:

dayum, it's not the prettiest block I've ever seen , but amazing and very cool to have that kind of machining abilities available .


Imagine if he would apply himself to making a Type 912 block and i'm not talking the car model but the engine model eg 917 block.

So this

in billet

Jeff is correct and nothing functionally wrong with it,

I'm just used to seeing a much finer stepover or no visible step over between cutting paths

F1 machined parts are designed to the lowest possible safety factor so every detail is critical

Final machined quality of the below parts is what I'm used and expect so that picture hurt my eyes

Hydraulic steering rack


Gearbox casing cover plate, probably not top team F1 or even F1 as it's just not got the right attention to detail level, at a guess if could be a Formula E part


Used this company, some pictures of their machining quality

Sectors - Blackmore Precision Engineering

Pushed the design so far on wall thicknesses that the internal surfaces required supporting when the outer surfaces were final machined to stop the part deflecting away from the cutter

Impressive.
