    I built Sid's 1.5x1.5 engine. It is a perfect project for those of of us that have hands that size wise look like a bunch of Bananas. The smallest fastener is a #4-40 but most are larger.

    I agree that getting a "cover" is a bit of an "Ego Pump". Sid is a couple ahead of Brian and myself.

    Only wish I had more time to write and publish.

    I inquired about having a book of my engine plans published, similar to stuff that Philip Duclos has done. I was told that books like that have such a small readership that it wouldn't be economically feasible. I believe that. I was told that if I wanted I could "self publish" but that I might never get my money back unless I lived to be 175 years old. I don't really need that. It gives me a great buzz to see one of my engines on the cover of a magazine, the same way it gives me a buzz to see my short stories published. I don't think that at 70 I'm about to start a new career as a writer of short stories or engine plans, but it makes me feel good.---Brian

    Brian- To be clear, the book shown was published by Village Press. My engines just happen to be on the cover, and the large engine detailed inside.

    First thank you for the plans, looks like a great little engine. I plan to build one in the fall as I will be unable to do so before then. In the meantime I have purchased the commercial parts before I start making chips to make sure I don't run in to any snags down the road. I don't have a lot of engine experience but Ihave built three steam engines and one hit and miss engine. I Feel I can hold my own mechanically and with with machining. I am however deficient in electrical smarts. I did not see an electrical diagram and I suppose that it's a no brainier to those more experienced than I but not to me.
    If anyone could offer help in this area it would be greatly appreciated.Would it be similar to my Red Wing hit and miss?
    I do have a few other questions. Am I right in assuming that the gears are not commercially available?
    I did not see a drawing for a piston ring. does the engine require one or is an O ring used?
    Thanks
    Ron

    Ronzo--You're kind of late to the party, this engine was actually built a couple of years ago. I cut my own gears with a set of 24 DP gearcutters, and I honestly don't know if the gears are commercially available or not. The piston ring is a Viton o-ring with a 1/16" cross section and an o.d. to match the cylinder bore. The electrics--well, wire from positive side of battery to on/off switch. Wire from other side of on/off switch to + side of 12 volt coil. Wire from - side of coil to terminal on ignition points. Ground wire from engine to negative side of 12 volt battery. Every time the points open, it breaks the circuit and this generates a high tension spark at the coil. Coil wire goes to sparkplug.---Brian Rupnow

    I guess I am late to the party but I waited for the final drawings in The Home Shop Machinist. As I said I can't start the project until this fall but I'm very eager.
    Your very timely reply helps a lot
    Thanks again
    Ron
