Building the inner molds will be the hard part, especially when taking into account the shrinkage of the casting- other than that, the casting itself will probably be very inexpensive. The final machining on the other hand, will be quite expensive and that's something you would probably want done in an English-speaking country. Brendan
well, I think this is far beyond my skillset or timeframe, but... I planned on putting a small machine shop in the barn, might as well add a smelter to the list of things to buy/build/have.
My noggin tells me that a beast of a diesel would be a 24 valve V6 tdi alluminum top & bottom all cast as a single piece - with water jackets...you would have to install the valves with a grippy arm tool from the bottom of each of the cylinder sleeves.

I hope if you want precision output you climate control to 72 degrees winter / summer. That is the one biggest mistake new shops make. Otherwise you'll only machine things to China's standards ;-)

Speaking of which, what kind of figures do you think we are looking at. 1K, 1500, 2K each?If all goes well maybe 500 USD per, possibly less if plain jane cast is used.

holy crap, then put me down for 6!
enough boost is when you have 3 dimple marks in the hood from the valve cover nuts..

Otherwise you'll only machine things to China's standards ;-)if it has to be 72, we could have trouble, it'll be easier to insulate the loft, and control temperature, but getting my machineshop up there will be difficult, and i'm pretty sure the load rating isn't capable of heavy equipment. I'll probably have to settle for finishing a room on the corner of the barn, and insulating/heating/cooling that. I'm not too worried, thats gonna be a couple years down the road yet. for now, tolerances will be "does the bolt/hose/bracket/etc fit?"
If you are going to make precision parts, yeah, 72... if your market is going to be less so, go for it with what you have - I had a business parter who got a contract with Cadillac making bumper brackets in a corner of his warehouse - no a/c but heated in summer. Worked great and he had one machinist punching them out with a small press.

I don't plan on marketing anything, unless things are much easier, and cheaper than I expect. I can do temp/humidity control, but until my wvo genny is built it's not gonna be cheap enough to justify. geothermal heat/cooling, with additional as needed. it doesn't get stupid hot here all that often, and I don't plan on working in a machineshop when it's sunny and 90.stupid question. am i gonna ruin any of those tight tolerance machining tools with temp fluctuations? it seems like it'd only be important to keep climate controlled while working. Am I wrong?
