Thanks for your help. Dennis

Being a 9 in lathe there is only about 2.4" to spindle center above the T slots Dennis

Hi I have been thinking about how to do the air cooled Red Wing engine on my 9 x 20 lathe. I was thinking about doing the bore as a line bore operation, moving the cylinder mounted on the carriage. So I am looking for a set of print / instructions. I would buy a used set of prints from...

THe kit is sold by PM Reasearch. THe Red Wing air cooled engine Dennis

Hi I am interested in the 1/3 scale air cooled engine dimensions. I need to acess if I can do the kit on my 9 x 20 lathe and little else machinery. Dennis

Hi Does this look normal for these coils?

The coil I just built measured 7 ohms I will try to see what kind of sparks it generates. Dennis

Hi My start on a coil for an igniter. I had some brass and a length of cast iron rod. After silver solder to hold the brass to the cast rod and truing up the brass I coated the cast rod and brass with some epoxy to insulate the enameled wire. The epoxy is hardening on the wire while I took this...

Hi Hank you . I think I have enough info to start a coil. Dennis

Hi Back emf. which is why a capacitor is needed in a points high tension ignition system. I remember the old days when a car would need new points when they got eroded from arcing when a cap went bad. Probably the points in a igniter could benefit from a cover bead of silver solder since...

I have some cast iron rod 5 1/2 x .840 diameter. What wire size do you think for the coil. I know too thin is hard to handle I have previously wound some coils on my mini lathe. It will spin slow and steady. THanks Dennis

Hi I am thinking about starting an engine with an igniter. The mechanical switch in the cylinder is fairly simple. Does any one have guidance or plans for the inductor coil. THe coils I read about call for soft iron. Will some of the leaded steels be soft enough or do I have to hunt up some...

Hi I finally got a full run on the engine, tank full to empty. I am running the original Champion VR 2 plug. This plug has a central point. The spark jumps to the thread edge. The corian plug, the central pin went almost to the thread edge. A "J" shape. .a very short spark gap. They called this...
