| BMW V8 dry sump from billet |

Well Ade, As I said it was just a thought. Yes, your right, add the word "billet" and the price automatically goes up. Same over here in the states. I usally take a piece of 1/4" square aluminum and tell them this is also a billet, although a small one. :lol: Perhaps looking into CNCing the mill would help increase production time. Just things to consider. You never know. Good luck when you get to the real thing. Bernd |

Bernd - it was a good thought too, and I'm always up for new ideas even if I don't pursue them straight away (or, indeed, at all! I'm notorious for having many more projects on the go than I could possibly have the time, money or inclination to complete... Apparently, "billet" just means "metal bar": Since bars can be square, rectancular or round, then there's no problem with describing a squared up offcut as billet :) Interesting explanation here: http://www.motorcyclecruiser.com/tech/term_billet_explained/index.html Agreed about CNC... if I sell a couple, I'd probably earn enough to buy a CNC machine. Ironically, I could then charge even more money, because now it would be "CNC cut from billet"! It's a crazy old world.... 1/2hr to shop time.... |

Dave, I do hope so... I may have to persuade the old man to turn the keys over to me, if he doesn't drive fast enough this year! :lol: Anyway... no machining done tonight, I spent ages scratching my head wondering how I was going to mill the channels from the head drains down into the collection pipes. I'd have liked to give them nice curves and a smooth descent into the pipes, but that's not going to be possible on a manual machine. So instead, I figured I'd mill them level, and maybe 20mm deep,to the edge of the current slope into the sump; then slope them at a constant angle so they intersect with the side of the collection pipe. Hopefully, the following semi-crap-o-cad will make this clearer: SO, each line with an angle beside it will be milled with the sump set flat; I'll then re-set at the required angles to mill first the top 5 drains down to the collection tubes (B and C), then rotate 180 & mill the 4 channels into tubes A and C. I've chosen to pick the holes up in the order they're in, so I don't have to mill a channel across the top of any tube. This means I can keep the overall depth of the sump to around 50mm. It also means I don't have to cut any of the ribs, although the support at either end of the 3rd rib will be fairly minimal. The final operations will be to put a bit of a slope on the bottom of each gallery to angle towards the pickup. So.... tomorrow will involve the rotary table. I'd better re-assemble it, I guess! |

Ade, you might as well go all the way when you sell these and say "Aircraft Grade Aluminum". It's possible that this could actually be aircraft grade. I know, "Billet" is the hot term for marketing, just like other terms that don't make sense, like "turbo". (There is no turbo in my desktop computer, but it says turbo on the disc drive door.) Billet is foundry metal put into a basic unfinished or semi finished shape. It's what extruder plants and finishing foundries buy to form finished shapes, like tubing, shafts, finished square or rectangles, like what you buy at the metal yard. Also, forging foundries use it, since there is no sense in buying finished metal just to run it through a stamp forge and turn it into a completely different finished metal shape. I know! Call it CNC Billet Aricraft Aluminum. Just kidding. You won't have any trouble selling a good product that someone wants, what ever you call it. I'm still watching and enjoying your project. Thanks for all the pics you've put up for us! Dean |
