Thanks Neil. I just enjoy having a go - I have no academic flair what so ever, but learning practical skills in my own time has been very enjoyable.

Phill.

Slide valve would be great, but I think a bit beyond me! It would have to be hot tube too..

Trying to keep it simple, I stand a better chance of it working.

Nah - carrier flame ignition and a whole new world of problems to solve!

Nice work as ever.

Hand wheel of a union drill might be a cheap option they are heavy enough!

Hot tube shouldn't be a problem as you would make it so that it could be screwed in the place of the plug, and f conditions don't allow hot tube running then simply remove it and refit the plug and carry on on with ht ignition.

I'd go for hot tube too, doing away with the need for a mag and setting up timing etc. Also a rotary sideshaft with a "face-cam" to operate the exhaust valve, and throttle governing to do away with a hit and miss latching system, which would be very fiddly on such a small engine. Believe me, I know!!!
With Your skills I bet You could make a super little flyball governor!!

The plan is to keep the engine as simple as possible, it's been pointed out to me by several people that the small size of the engine will probably make it more than slightly erratic if built as a hit and miss and I think that's very valid. To begin with, it will be built as an ungoverned four stroke. Once satisfied with the running, some form of governor can be designed and added. The idea of a belt driven flyball governor appeals to me.

The compressor has finally been completely dismantled, the crank looked a bit of a mess but pleasingly the bore and piston are unworn.

The crank has cleaned up for a bit of a polish - for what this is, I'm not worried. If the thing turns out to be a rip roaring success then I'll look at making some proper bronze or white metal bearings - the crankcase is small enough to bore oversize on the lathe and the crank could be undersized a little. The pulley had obviously slipped at some time, wearing that part of the crank - a light skim has made it round again!

A stub has been turned on the back end of the crank, this is to drive the cam.

The shaft will have a keyway milled for the gear.

The piston is remarkably well made compared to the rest of the compressor.

The bolt in the foreground is the first of the new head bolts, 5/16" ANC. The thread was machine cut but I found it necessary to finish with a die, two more to make now.

Very sturdy looking crank for the size of machine.
