Ron's Jowitt Popett Valve Engine

A bit of video of the Jowitt running on the new compressor, no sound I,m afraid as the compressor is so noisy it drowns the engine sound. I need to get an airline extension to get the compressor outside the workshop. I had another problem in that the in line regulator developed a leak so had to remove it from the line which left me trying to control the engine on the compressor regulator. Also had to hold down the engine to stop it walking across the bench, it hasnt got its base fitted yet. Anyway enough of my excuses at least the video does show the engine has a good turn of speed with the better delivery of air.

Well done Ron. Coat of paint and a base and it's on to the next one.

I'm surprised we dont see more of these Jowitts, as you found they're a little bit out of the ordinary run of steam engine and with care produce a good looking result.

Would be better with a Chuff, Chuff, Chuff.

What you can do is set the compressor reg to about 5psi and fill the tank then switch off, depending on size of engine and speed you run at you can get a quiet run that's what all my videos are done like. That Muncaster No1 I did recently goes for 38mins off my 20lts tank.

Thanks Jim, I am on to the next one actually, I,m half way through Jasons Entablature and thats a nice build also.

Good idea Jason I will give that a try.

I didnt make too good a job of the flywheels did I, they are annoying me. I should have set them up to the inside of the rim or as close as you can before machining the outside but I didnt. The outside of the rims run true enough but its amazing how the out of true inner grabs your eye.

Oh well you live and learn, at least the entablature wheel wont have that problem.
