I'm at the decision point whether to update and expand the book, or develop plans for larger machines.
I vote both, lol. Personally I'd prefer the book update but whatever brings in the cash is ... |

Hurray! I finally got my pump working. New capacitor, seals, gaskets, cylinder cups and liners. The biggest pain was that the piston heads were held on with brass bolts that were cemented in place s ... |

You can get a pretty nice rebuilt pump on eBay for about $50. I bought a dud and rebuilt it myself but it ended up costing me about as much as a professionally rebuilt one would. The guy that sold m ... |

Also, isn't that the CFM at the source? If you constrict it to connect to the vacuum former I don't think it will be pulling anywhere near 1000 CFM. |

Has anyone used like a teflon coated hotplate for the underside oven or does the plastic stick?

When I looked at it, I saw a space across the front of the sink that I took to be the drain. The inside far corner, top, isn't in the right place for that to be a wall.
That would be a cool drain b ... |

Nice sink. I have considered making a few small basins myself but never tried. Do you spray those forms or just do a standard pour? Also what do you seal them with?
Why no drain? |
