Craig,

The cam holder I can't lay claim to building. It is the Porsche factory tool.

I thought I had a photo of this pair of tools in use taking off a stubborn cam nut, but I can't find it. For that pupose, these tools are supplemented by another set of home-made tools, a couple of pieces of 3/4" galvanized pipe. One piece fits over the end of the cam holder and reaches from there to the floor at about a 45 deg angle, off to the left. That is the cam holder. The other piece of pipe (about 3' long) fits over a 1/2" ratchet handle attached to the crow-foot. This makes pretty easy work of over-tight cam nuts.

I have never had consistent good luck with using an impact wrench in this application. There's not much mass in the cam itself, so you need to counterhold the cam with some sort of tool. Of course you could use the breaker-bar-on-the-cam-holder like I use for this purpose, but then you don't really need the impact wrench if you have another piece of 3/4" pipe. ;^]
