Hello Again.
The electrical pressure switches work on the same principal as the gasoline compressor head un-loader switches, good to think of them they totally slipped my mind. He He He

Hello Friends, Yes of course the switches have an electrical application. They work by a mechanical diaphragm and that diaphragm mechanically releases the pressure on the compressor head by actuating a small valve on the side of the switch. I have had them apart many times. I do realize electronics ...

Hello Glenn, Some air compressors have a exhaust valve pressure switch. Perhaps you could use one of these to serve as your relief of the air pressure when you reach a set pressure point. the air relief mechanism of one of these switches is mechanical in its function. The relief valve is rather smal...

Hello friends I think Johnny O is referring to a water glass water column. These are basically a pipe connected to the back head of the boiler above and below the the waterline. the water glass and try cocks were then attached to this. The water inside the column would stay relatively calm compared ...

Hi Harold,
So happy to hear you are out and about.

Hello Harold,
Lets hope this is only a minor stumble in your life. I am still looking forward to our meeting when I can visit the states again.
Get well soon
Karel

Hello Pat,
I think to say steep learning curve would be an understatement. Congratulations nice model.
Karel

Hello Friends,
Tools and Manufacturing Engineers Handbook is available on the Internet Archive.

A wonderful resource for titles of many books pertaining to many of the things that interest all of us.
Cheers
Karel

Hello Squandit,
Have look here:

This book contains a wealth of information on locomotive mechanical design page 15 talks about steam consumption and pump sizing.
Happy building

Hi Marty, That makes it more complicated, could you turn the fly crank thinner with a boss that would press into the wheel and press the axle into a smaller hole in the fly crank. that would also give you the counterweight with a little re profiling. Grabbing at straws perhaps castings would be easi...

Hi Marty Would it be possible to attach a counterweight with a boss for the crank pin to the wheel you have ? I am willing to make a pattern and have some cast for you but I think it might be a while before you might have them due to the current health emergency. :cry: . Ocean shipping cost should b...

Hi Scotty, Until the cylinders are warmed up you will have condensation in the cylinder. If there will be enough enough to cause a problem I can not say for sure. A slide valve engine will force condensation past the valve where as a piston valve engine might be damaged. Since you are making your ow...
