Re: Steam Age Boilers

No I don't, I thought you needed the drawing. What you are looking for would have supplied to the buyer with the boiler.

Re: Steam Age Boilers

I just dug through all of the Steam Age boiler drawings that I have and did not find a drawing for a RRSC 4-4-0 steel boiler. Sorry if I got your hopes up.

Re: Steam Age Boilers

Most Steam Age boilers were built to the original manufacturers prints, although sometimes if the owner wanted something custom new prints were drawn, I have some of the revised drawings. Send me the name of the person who ordered the boiler, type of engine, and some idea of the date and I will chec...

Re: Lubricator

I use two clicks on my Mikado, still uses oil a little quick, I just added on to the reservior, made it about triple the original size and made the top lift off to fill. I didn't like the screw cap, it was difficult to operate with gloves on.

Re: LE Rotary Throttle Build

I built one a couple of months ago for my Mikado, I didn’t use castings, just used stock. It works great and is able to handle much higher heat than any commercial valve the I have found. I followed the prints with one exception, I made the ports larger because I wanted the throttle lever to have a ...

Re: Re-light an oil burner

The link above to model engine plans, they sell a kit for a buzz coil, works great on my Oil fired Mikado. Works on 6 or 12 volts, I used a champion heater igniter has about a 2" reach so it is closer to the fuel spray. Works great.

Re: Throttle valve -again

No clue as to how much if any superheat, but I am getting dry steam. No doubt about the smoke box temp being high, but I see guys firing as hard or harder and they don’t seam to have any trouble with valves. I think i am just going to build a new throttle, it should handle the heat better.

Throttle valve -again

OK here we go again, after burning out the last throttle valve ( ball valve with graphite seats ), on my oil fired 1.6 Mikado, I rebuilt my super heater to reduce the amount of superheat, and replaced the ball valve with a fast opening gate valve. I just fired it for the first time after the change ...

Re: Super heated Steam Throttle Lag

I have enjoyed following this thread, I just got my Heavy Mikado fired up a few months ago, it has a superheater. I am in the process of decreasing the amount of superheat because I am destroying throttle valves. Originally my superheater elements ran all the way to the back of the firebox, I am goi...

Re: Mikado first run

As for the location of the valve I had a very difficult time deciding if it should be up or downstream of the superheater, I chose downstream for simplicity of piping and I also thought it would be more efficient (steam would have more time in the superheater) and also not be susceptible to runaway ...

Re: Mikado first run

The valve I am using came from McMaster Carr, it actually is rated for 550 degrees, I looked at so many that I got all the specs mixed up. It was $188, the 750 degree valve was over $600 from a valve supplier, McMasters price was actually pretty good. I am happy with the new valve, hope it lasts a l...

Re: Mikado first run

My original throttle valve was a steam rated 90 degree ball valve, it said not to use it for throttling, and they were right. The problem is that there is only one end of the ball that has a seal on the 90degree valves, and the seal was Teflon so it began to flow and not let the throttle close. I fi...
