Re: Things to do in Florida in January?

Stephen, I didn't realize things were that bad down there. Prior to your post I only thought the only thing they try stealing in that area of Florida was elections with the help of magic boxes of ballots that pop up out of nowhere! :D Technically I will be working in Miramar but free on the weekends...

Things to do in Florida in January?

I am going to be down in the Miami area Florida the weekends of Jan 12, 13 and Jan 19, 20th for work and free on the weekends. I have some relatives up in West Palm beach to visit but should have some time to go touring around. Especially with the company paying for hotels it never hurts to go somew...

Re: Using a steam indicator

On the subject of CAD, the drawing you are looking for is a 2minute sketch that can be done by hand, and is probably takes no more than 15mins to make start to finish on both the lathe and mill. No need for CNC here, in fact CNC most likely would slow you down trying to use it for one part. Since th...

Re: Using a steam indicator

Dick, Yes you are right about pressure transducers, we do a ton of hydraulic measurement and use this rubber hose that maybe has about 0.025"dia and it works great. I always marvel at how well 30ft of this hose still gives me good measurements. I have seen over 4ft delays maybe on the order of 2-4mi...

Re: Using a steam indicator

I took a look at those pictures and my recommendation stands, take the 4 screws out and make a dummy cylinder head that the pressure transducer screws into. Sure it will look goofy but who cares, using some very tiny tubing is going to introduce a host of new variables and problems that you don't wa...

Re: Cleaning a smoke box?

Who needs solvent or cleaner? The way a smoke box is normally cleaned is with the locomotive on the steaming bay you just take the smokebox cover off the locomotive, you get a blowgun with a long tube on the end and stick it in the firebox. Usually it is best to wait until that time of day when a la...

Re: Using a steam indicator

Here is an article published by the PLS Gazette that covers the topic of steam engine indicators: http://www.palivesteamers.org/pubs/gazette/2013_3-4.pdf The article mentions two British model engineers who made serious, well documented tests of miniature steam engines using electronics-based indic...

Re: Using a steam indicator

Steve your response had me a bit confused but upon digging a little deeper I think we must be talking different ends of the stroke. I think you are talking about the last bit of compression on the return stroke that occurs when your exhaust valve closes before your inlet port opens. This is where yo...

Re: Using a steam indicator

So I would have to drill holes for cylinder drains in order to use an indicator on this engine? Or could I still get an indicator reading by just putting a tee in the steam inlet just before the steam chest? The reason I ask is because it's a very small cylinder and as far as I'm aware, nobody even...

Re: 15” ga live steam club feasibility

I don't think this is too far from feasible. Roll models locomotives are pretty popular at lots of clubs especially in the west. I just measured mine and frame spacing is 13" for 7.25" gauge. I don't think it would be too hard to put the wheels on the outside of the frame and have a small easy to mo...

Re: Making a boiler without a lathe

Thank you all very much for the advice! Regarding my location, I am in Auburn, AL. The university has machine tools enough to construct a small country, but as far as I know I'm not allowed to use any of them until I take the mechanical engineering elective that teaches me how not to make myself in...

Centerville and Southwestern Railroad

Anyone here remember the Centerville and Southwestern Railroad? I was at the train show a few weeks ago in Springfield and a used 1955 pamphlet of the railroad caught my eye and came home with me. I found the info on it has later been reposted here http://ibls.org/mediawiki/index.php?title=Centervil...
