    Santa came early, the kind of Santa you have to pay. A big fat drum of ethanol arrived yesterday. Yay.

    Not too sure if you noticed Wobbly talking about doing some EngMod2T design work for a 35 cc RC engine, but turns out the guy is in Oz. He rang me about making pistons. Came down to the fact that he has a mate with a 5 axis CNC lathe who could machine them from solid blanks.

    So, as we were doing another casting batch of our pistons, I made up some simple CO2 moulds (ุ42 to suit a finished piston size of ุ38) , set these on a thick steel blank and poured it in. The idea being that the first/lower part would solidify first and be fed with the subsequent molten stuff above. Certainly some shrinkage in the upper section, but the lower section appeared to be ok with a single trial unit. Heat treated to T6.

    Loving the CO2 process, it’s just so quick. Makes me wonder why that Aussie guy in Husa’s post #4787 went to the trouble of using resin to harden the sand and wait a day for it to set. I reckon he just stuffed up making his sodium silicate in the first place.

    You wouldn't be designing an engine for Tony Grinter, would you? I met him years ago on a trip to Australia. We were playing with the electronic ignition system on Quickdraws at the time. He was asking me recently about inertial dyno design and construction. I would love to see what you can come up with to shake up the model boat racing world.

    Started making patterns for an exhaust stub/manifold for my Lambretta Imola cylinder. The core can be changed to support a 75% - 90% of port area.

Im just jolly lucky no one has been training CNC staff for years so people like me still have some worth, after all. I was starting to think I might be unenployable at my age.
    That went well, two and a half days, went home and never went back. This working with others, not for me.

    That's the problem with other people .

    . . Well, actually there's a list.

    And it keeps growing.
    I've been told. Dreaming`s free.
    Think I'll go, back to sleep.

    I know the feeling. Working for others is not for me. I enjoy doing work that makes sense to me, not useless work assigned by thoughtless managers. But working with other people who have the same goal can be quite satisfying.
    Working with me can be demanding, though. I may keep looking for the optimal solution while others would already have finished the same job in their sub-optimal way. But in defense of my market value I must say that I am quite good at finding simple solutions to both theoretical and practical problems.

    Amen brother. I kept being frustrated in all the various organizations I worked. I'm now on my second business where I have a great crew. I'm the boss but they handle the frustrating details. Besides, we need to hear about your opposed piston engine.

    I was quite shocked at the state of the business I worked for. Had me first up using a CNC that had a broken tool changer, had to line the tools up on the bench and load in order otherwise a mess. I was under the impression the toll changer had failed just reciently. The boss talked to me about getting a new machine. On talking to the boys in the shop I find its been out of order for ten years and the boss is always promising a new machine every year. Every bloody machine has a different control, none hooked to a central computer. I am so lucky to have full 3D Gibs Cam with off line progaming, I did not realise how advanced my little workshop is.
    Then they wanted me to manually machine up a pair of B section pulleys, four belts ie matched sets, on a manual lathe with no digital read out. Possible but fraught with danger of mistake and slow.
    So I loaded everything on my truck, went home and machined them out on my CNC. Delivered them back and said thats it, this workshop is not for me.
    They had two CNC lathes, one busy all the time, the other, you guessed it, broken. Not what this company once was back when I used to do business with them.
