I guess I need to explane more. Even with an hour to work (OK play), I find myself at the bottom of the site glass and still have not finished the work I wanted to do such as switching. It is a real pain to blow down the boiler, let things cool off, fill the boiler, get both burners burning, build steam, and then finish the job (takes 30 minutes to turn the engine around).
I want to keep things very simple and want to stay away from tender type pumps. With a boiler this size, no real need to keep a constant boiler level. The pump bottle with a Goodall valve is exactly what I need and works fine except it takes a very long time to pump 500cc with the squirt bottle I have and my finger gets worn out. I just want to find an electric version of the hand pump. Every hour, I just need to be able to inject 500cc at pressure and keep on going (OK, I still have to shut down to refuel and add oil). If I refill the boiler every 1/2 hour, I probably will have minimum heating time to rebuild pressure. I came up with 250cc/minute as a couple of minutes to fill the boiler sounded reasonable. I just have yet to think of an application or sorce of a suitably sized commercially available electric pump. I could build one but I am sure there is probably a cheep one available that does what I want. My alternative plan is to use a presurized water bottle connected to an air compressor in the garage. Don't tell me this is something new? Regards, Tom Burns
