Re: digital steam engine indicator

That's wonderful Ramón. I'd be willing to buy a set and coded package if you were to market it. (I have no coding experience, nor desire to use my limited availability of cranium space to learn it...)

Re: SL Walkin' Belle is For Sale

Pete,

She looks like a wonderful time on the water,. And a real attention-getter. I'm sure many would love to see more detailed photos of the machinery, along with bore+stroke and sqft/hs dimensions, etc...

Re: Re-using oil

Haha I like your W.I.N. assessment. Usually winter for us means experimenting or finding solutions to problems that don't exist. Like making something inherently ineffecient into something incrementally less ineffecient (or sometimes orders of magnitude MORE inefficient if it didn't work out). Hard ...

Re-using oil

Curious if anyone has risked re-using their oil from their engines? I know oil is cheap compared to bearings, and most don't use very much in a run, or even a season. Now that we're using nearly a quart a run or more (we run 4-8hrs at a time regularly) several times a month, I'm wondering about havi...

Re: Semple engines

Thank you very much for that! It's interesting they don't give dimensions for the overall thickness of the valve chest, valve chest face to valve stem centerline, nor the valve face to cylinder bore center. Seems a lot of "fitting" was needed in our toys because a lot of dimensions were never given...

Re: My new boiler - a watertube-type

Your design looks very nice. I think you will be quite pleased with a larger Ofeldt. Natural circulation is wonderful in them... Surely you've experienced how quickly they build steam and with such abundance.

Semple engines

Longshot request... Wondering if someone might have drawing or would be able to get me the full dimensions of the cylinder for the 3x4" 5hp Fred Semple single (and/or the HP cylinder on the 3+5x4 v-compound, which is the same) including the valve stem to piston rod distance (or piston rod centerline...

Re: Compound engine cylinder proportion

Here are the dimensions of some compounds I'm intimately familiar with: Grosejean compound 2" & 4" x 3.25" William Charles Grosejean was a mechanical engineer and designed his engine with maximum efficiency in mind, keeping within the constraints of Stephenson link valve gear, and 150psi steam (500°...

Re: Steam Thistle Clauran

I've never been to train mountain. It's definitely on my list. First I need to invest in a locomotive... A friend of ours sells kits for 2 and 3-truck Shays. I've always loved Shays. Klamath is on my list for sure. Hopefully I can swing it this year. Don Mentzer always tried to get us to go when he ...
