Steam Engine Design Help Needed

<< < (2/4) > >>

Sackett:
Yeah, I guess a bit more info would help. I've looked at elmers n tiny power n coles n stuarts n I dont know how many more.The engine I'm looking for is usualy called mill type or box bed . They were designed to power shops and mills. Horizontal 3in bore x 5inch stroke is idealy what I'm looking, but close would work,
I need something for real work at off grid site for battery charging, water pumping , grain grinding ect, general main power source. I can find lots of pics n old engravings, but no plans that I could use to make patterns, n sadly I lack the drafting skills to do it myself.Found a foundry on west coast willing to help with patterns and casting ,,but no plans yet

sbwhart:
This is the engine you want.



The engine is at the Northern Mill Engine Society at Bolton http://www.nmes.org/ they have maintenance days every Wednesday if you go along I know they will make you welcome and let you photograph and measure the engine to death.

Sackett:
Thanks sbwharts,, sadly I'm in states,,although I guess one could email n see if any plans / drawings available. But yes that engine looks about right

Jasonb:
You could base it on something like the Clarkson 2x2 which could easily be scaled up to 3" bore and stretched out a bit more but I would tend to keep it a shorter stroke and have it reving a bit faster, most of the steam driven gen sets use enclosed crankcase high speed steam engines.

This is a picture of the clarkson that I found on the net, castings would be quite simple or would not be hard to do it all by fabrication or cutting from solid. Flywheel on the 2x2 is 6" so 9-10" on a 3inch bore version, as its to work and not look at a soldi disc flywheel would be fine.



Blackgates here in the UK now own teh rights so should be able to supply plans

Sackett:
Working on some drawings,although progress is slow. Another member has contacted me offering some assistance, which is greatly appreciated.Maybe we can get this project moving along soon.
I kinda backed into a deal this past week,,,3200+ lbs of Millwauke horizontal milling machine ,,, for peanuts. Yeah, I know its obsolete , n no havent seen it run ,, but one's gotta start somewhere :beer:
