Billet Adjustable Cam Pulleys

After lots of delays and other bullshit ive finally programmed and made the protype inners.

Now I can work out some anodising. Hopefully it wont be too much longer till our 4th axis arrives so I can actually use the 1200$ worth of custom carbide tooling to cut the teeth.

Its getting closer to completion..

Fixture and program for the PCD threads in the belt ring done. The stock cam position trigger fits like a glove.

I just need to optimise the lathe programs to better suit production. As i just did it quick and dirty to rattle off the prototypes.

Hopefully the global supply chain being fucked at the moment doesnt hurt me too much in wait time for the equipment to cut the teeth onto the outer.

Finally becoming relality though

I actually quite like the raw metal look so far

The outers will be black regardless as they need to be hard anodized for wear resistance or the belt will just eat into the aluminum.
You can anodized the centers a natural/clear finish if so desired.

Looking good Adam.

Well after the first set is done and on a running engine to test ill be hopefully doing batches of 10 sets

First set is at the Anodisers getting some colour. Hopefully their processes are as consistent as they say they are so I dont have to adjust my tolerances for the fit too much

The Anodising sample is back. Looks pretty slick I think.

Thoughts? Keeping in mind the belt ring will be black as thats the only colour they do the hard anodising in.
