Wow, I want one too

Looks like something Lotus built, "Maybe" ?

Thanks Crankincraig, The tiny4 took about a 10 months to build and was easy to make run. It was a fun build. I've seen Steves Little Demon and it is a beautiful engine, On my list for sure. Good luck with your tiny4 and keep us up to date. Gary

Great idea Scott, I'll remember that one. Thanks Gary

Thanks Baron, I can build an engine with less aggravation than posting a picture. I need to go back to school.

Thanks Crankshafter, I'll try again,

Here's my tiny 4, this is my first time trying to up load pics, I hope it works. Gary

Nice job Rich, She looks & runs great. Congratulations, Gary

Weez, The cylinder was sleeved with CI lapped to glass smooth finish, piston aluminum with 1 Oring made of silicone. I found quite a difference in Oring materials. From my experience the Oring works best if it barely touches the cylinder, Always remember to reduce friction anywhere you can when...

Hi Weez, My first IC engine was the Kerzel and still one of my favorite engines. The prints are great. I also learned to cut my first gears, spoke flywheel and sparkplug. The motor runs cool without coolant for hours, starts first flick of the flywheel. Gary

Beautiful job on that Stirling 60. Did you get your Kerzel straighten out?

Hi Graham, Years ago I had a collection of 30s & 40s tether cars that I regretfully sold. The only one I kept was a Dooling F with a McCoy red head. Somewhere in my stuff there are assembly prints for a Syncro Rocket. These were about full sized & very complete with chassis, body & engine but no...

Hi Mike, I have not used the glass cutter from McMaster Carr, but all of my attempts to cut pyrex tubes had failed until I used the following method. Spiral wrap entire tube with one layer of masking tape, scribe to the desired length through the tape only, very gently clamp the tube in...

Hi Rich, I just remembered the problem I had was battery voltage when I first started my engine, it would fire once or twice then quit. added a charger and life became much better. I hope this helps. You will have it running soon. Good luck, Gary

I cut the oring groove till the oring barely touched the cylinder, The cylinder was lapped to a glass smooth finish the auto buffing compound.Gary

I don't use oil in the fuel, I used a silicone oring for the piston ring. Silicone is much softer rubber than viton and still holds up to the combustion temperatures. When first starting my engine I used generous amounts of oil in the rear of the cylinder & on the valve guides. I believe that...

Hi Rich, Your exhaust valve should start to open just after bdc & close approx. at tdc, If the exhaust valve is opening a little early or closing a little late you can increase the valve lash to correct that. Ignition about tdc. You should hear the intake valve make a burping or sucking sound on...

Hi Brian, Your special crankshaft cutting tools could easily be modified to cut this recess, Just watch your clearances. Regards Gary

Great idea, I'm anxious to see this one progress. Good luck with the egg. Gary

Hi Brian, sorry to hear about your crash, we've all had that happen more than once. My solution for a day like that comes in a clear bottle labeled Dewars, all you have to do is add ice, works like magic. The normal disclaimers, I'm in no way affiliated with this company. just good...
