Re: Simple Condensor Design?

The vacuum in a condenser is created by the reduction in volume of the condensing steam. A pump will be required to extract the condensate and maintain the vacuum. If your goal, as in Mikes case, is to reuse the water in order to extend his range, then a simple tube of the right length will work fin...

Re: Removing boiler tubes

Years ago there was a boat shop down the road from us that had the boiler from an old Case portable engine to supply the steam box. When it came time to replace some of the tubes, the owner showed me some copper sleeves that just slipped over the tube ends rolled in on one end so as not to slide on ...

Re: Theory question: Pressure/temperature limits

Okay I couldn't resist,
3Fe + 4H2O --> Fe3O4(Magnetite) + 4H2
The Iron must be red hot and the water in the form of steam.

Re: Theory question: Pressure/temperature limits

The Mechanic's Magazine, Museum, Register, Journal and Gazette Volume 29 1838 Page 360 " The Victoria Explosion Inquest" talks of the reaction of red hot iron absorbing oxygen and liberating hydrogen as part of the reaction. In my youth I read of early steamboat boiler explosions often being accompa...

Re: 1893 Marine Steam Engineers Manual and Directory

Ron September 2019 we drove along the Mississippi from Minneapolis to New Madrid. I bought a paper back of the same book you are talking about before leaving Minneapolis. Though it doesn't quit read as a travel guide it really helped to picture what the river and its' navigation was like before the ...

I found it much quicker than I thought it would be. A little work with an angle grinder and a standard chisel could be modified. May not be worth the effort if only a couple of tubes are involved.

Good luck

Re: Removing boiler tubes

https://www.youtube.com/watch?v=vqnMJmjtvGw This might be a little over the top, but on a smaller scale the operation is much the same. Instead of a plane round nosed gouge a " safety ripping chisel " was used by the boilermakers when they removed a tube for inspection on the ship I was on. The tool...

Re: Con-rods and length

Mike, I recall seeing an engine, at the Port Orchard Meet, that was built by Don Mentzer? The crosshead guide consisted of a sealed ball bearings on each end of the crosshead pin that were captured in a slot formed by spacers between two pieces of heavy square stock. The engine for a time was listed...
