I've been meaning to post an update; sorry for the delay. It took me until this last weekend to get the first operation machining done on the intakes. Everything that could go wrong did, including broken tools, machine errors on both CNC machines, etc. (I was just comiserating with Barry R tonight about all this...)
In fact a couple weeks ago I was so frustrated with how things were going with my smaller CNC machine, the one that is doing the center cover plates and road draft tube covers, that I started hunting around for another CNC machine to replace that one
As luck would have it, a machine showed up on ebay that fit the bill perfectly, and the motivated seller gave me a pretty good deal on it. So now, I have more work to do; I have to move my smaller CNC machine to a different location in my shop, and get the shop ready for the new machine. Hopefully the new machine will run better.
Back to the manifolds, I am machining the first one on the second operation tonight. Hopefully it will be finished by tomorrow, then it has to be leak checked, have the thermostat housing holes and water bypass holes drilled and tapped, etc. I'm not counting on ANYTHING at this point, because the problems I've had over the last month have far exceeded what I expected. But hopefully, the finished manifolds will start to come out now. We will see. Thanks to you David, and everyone else on the list, for your patience on this - Jay
