I know what it is, but I'll stay quiet to keep the fun going. Looking good, by the way!

Correct.

They are "extra heavy" exp wedges. Hopefully they provide enough force to lock up the clutch on my Cr500 at the relatively low RPM where it starts making Tq.

Interesting... I wonder if I'll have slippage when I go from the G2Ergo 400 cam to the 200 cam (which I'll probably do on my next dryish ride). I know you say the 250s will slip a lot with the exp but it hasn't been an issue for me yet...

Are you just using plain brass? There are denser materials out there if you need them. Let me know. I have some stuff laying around.

Yeah Its just 836.

I was going to go with one of the machinable tungsten's, but the cost was the deciding factor. It shouldn't matter as I was able to offset the density issue by just making them bigger in a few areas (I also have TC balls to use as the bearings)

Out of curiosity what do you have available?

The cam shouldn't make a difference.

I've come to realize that some people can make anything slip. I've talked to a few people that insist a core EXP slips on a YZ 250 to the point of burning plates in a few hours...

If yours works well

Cool, I haven't tended to have clutch issues so I suppose I'm ok.

Because you most likely could not. You would need a diamond to cut it. Or grind it. Still a bitch.

EDM would be your best bet for cutting tungsten into those shapes.
