My First I/C Engine

Hello,

I would like to take a moment to introduce you to my first attempt at building my first I/C Petrol Engine.

After building several stationary steam engines from castings (Stuart 10V and Victoria Single) and from bar stock I decided to take the plunge with Hamilton Upshur’s Farm Engine build which he drew up in 1977. Tinker John (YouTube) also built this particular engine.

I bought in the camshaft/crankshaft 2:1 ratio gears, the spark plug and used electronic ignition instead of contact breaker points.

I have thoroughly enjoyed this build and the challenges that went with it. To say that I was chuffed when it burst into life for the first time is an understatement… https://m.youtube.com/watch?v=RyIQ-ncQF7o

My next build will be the horizontal version of the same engine with a unique difference. I intend running this version on propane gas. I have sourced the diaphragm and plans for the demand valve from a company in the USA and will start the build shortly.

I chose this engine after researching Hamilton Upshur who I found an interesting chap and I did not want a messy 2 Stroke.

I have taken lots and lots of photos of the build so if there’s anyone interested in undertaking this as a project and needs advice… just send me an email tom@clangullan.plus.com

Looks and sounds good Tom.

Nice, I like the sound too!

I like that, Tom

The Propane fuelled horizontal should be interesting ... any idea what its power output might be ?

Gentlemen,

Thank you for your kind comments.

Michael... sorry, I have absolutely no idea what the outputs is. I have limited skills on my lathe and milling machine but I do like a challenge!

If you are interested in a little research into the performance of your engine, it would be worth making a Prony Brake, and getting a non contact tachometer, this way you can calculate the BHP of the motor.

Thank you Ian.
