Machined parts for V6
The last few years I have been machining sections from Aluminium to suit my V6. Thought I would post some of the photos. Rocker covers first side.  The second operation I machined a jig to the shape of the inner profile to locate the previously machined inside and also drilled and tapped the holes. Initially used hex bolts to hold the cover down and then in turn with the program machined each of the holes with a counter bore hole and install cap heads. I then machined the outer profile. Used a 12 mm long solid carbide cutter to get the depth. The carbide cutter has far less flex compared to the HSS cutter.

Number plate frames to suit MK3, the front mount backing plate is different to the rear plate. Bezel bolts on with 4 mm S/S cap screws and holds 2 mm clear poly-carbonate sheet and the number plate in place. To be black anodized as well.

Nice work...
Looks like it would have been a big chunk of Alu to start with!

I can really appreciate the hours you've put in for such beautiful machining, as I did 4 years in the machine shop when I did my apprenticeship in Toolmaking/Marine Engineering back in the 70's............wish I had the machines and the time to emulate your efforts for my own GTV6.
Well done !

Jamman,
A professionally machined rocker cover. More of your metal working skills that never fail to amaze. What next? How about a 4 litre, 4 bolt main alloy V6 block.
Regards
John

For install of the alternator on the right side I made a remote oil filter with -10 lines.

BMW E38 radiator. A lot of work to machine the mounts to suit the top and bottom rubber feet. Radiator was mounted forward of the front cross connection. Laser cut trims, folded and welded for the twin fans. Some of the wiring is temporary until it is completely changed over to EFI. The collection point tank for the water outlets have sensors for the dash gauge, injection control and the electric water pump.

Electric water pump with the combined control unit for the pumps and fans. No thermostat is required as the pump pulsing and speed controls the temperature. The water pump is mounted from the side bolts for the front suspension corner mount.

looks ace. Lovely work. (An aluminium block that takes later chambered heads of some type would be good)
