      Do you lubricate the cylinders? How?

      What other procedures should be done?

      And now back to your regularly scheduled program.

      Joe, we just pressure the boiler with air, leaving the water out.  Most engines can have an air line attached through the filler hole, though you may have to make an adapter to make the line fit the hole.

      I use a portable tire pump that I keep in my car anyway.  The air line doen't have to be a great fit - a rubber grommet or plug will give you enough time to open the throttle and see what happens. My pump has a variety of small adaptors for footballs, air matresses, etc, and I can usually persuade one to work in the hole. (Another pair of hands can be useful.) My last test was in the back of my small SUV which has a 12V outlet and a flat surface for the rollers.  Ah yes - you may need rollers so the loco can spin its wheels without going anywhere.  But a Ruby can be set on blocks under each end; probably no need for rollers.

      Alternatively, if the loco has a Goodall filler valve, then air can be pumped in through that, just as water would go in to fill the boiler. Or the check valve on the backhead (probably not present on a Ruby) willl usually have a pipe nozzle that you can attach a pipe onto.  Auto windshield washer pipe is the preferred tubing, as it is pressure resistant.

      If you plan to do it often, then make a proper adaptor to connect the air pump to a quick connect.  Jason can advise.

       

      With a new engine that has teflon o-rings or graphite tape you don't need lubrication as long as you only do a short test. It won't hurt to put some regular oil (not steam oil) in the cylinders when you bolt everything together, and that will help the testing.  You can try to drop some oil into the steam pipe so it finds its way into the valves and cylinders.

      Have fun!

    • John,

      I built, ran and tested aircraft for 37 years for Northrop/Grumman, but live steam is new to me. The only aeroplane I know of is John Hartford's song.

      John,

      I bought the built up Ruby#1. I figured I do not have enough live steam skills to put the kit together properly after reading several things on line about difficulties in assembly, parts that didn't quite fit correctly and parts missing in the kit. I will take it apart eventually, but for now I know it will run, everything is there and it's properly assembled by Accucraft! BTW RLD Hobbies and Reindeer Pass both have the best price.

       

      I got mine from Jason at The Train Department.

      It was a whim buy and as a retired Silversmith, I think I can get it running before the drop kick into the desert!

    • Very nice, look forward to seeing it run in Palm Coast, Ran my Mason Bogie Monday on Earl Saults layout for the first time and as soon as I can figure out how to post the video I will do so, all and all it ran great just needs a little more weight but it was great to see it run, have been working on it since June of last year, Bill

    • Did you get a built up model or the kit? I have a kit waiting for me to build her for summer runs.

      I'll be watching this thread for tips.

      Thanks

    • I purchased a Ruby #1 from RLD Hobbies. It will arrive in a few days. Thanks for your help.

    • What make is your live steamer ? If Roundhouse drop them a line, they are a very helpful company. they test all their products on air prior to shipping.

       

      Normally when you see videos of live steam locos running on compressed air the line is attached direct to the boiler filler. In normal operation, with a gas poker fired loco as opposed to a coal fired one (which has a separate firebox), when you fill with water you draw off a proportion to leave a space where the steam forms within the boiler barrel and then passes through the superheater pipe (if fitted) to the cylinders. Assuming you have a gas "poker" fired loco steam is generated and boiler pressure is maintained until the boiler runs out of water or the gas runs out. With a coal fired loco the water it is constantly refilled to avoid the firebox crown being exposed. As you are going to power with a flow of already compressed air you will feed that at the normal pressure the loco is designed/needs to raise in steam to function and at the right flow rate to maintain that pressure depending on the amount the regulator is opened.

       

      I am not sure about the need to lubricate the pistons - as you are running with cold air the only heat you will be generating in the cylinder will be from the friction of the cylinder seals against the cylinders bore, you are not going through a compression cycle in the cylinder and generating heat as you would with a compressor or putting hot superheated steam through them.

      Please help, I'm totally new to this part of model railroading.

    • mid $2000's with RC control.  I think direct from RH at current exchange rate mine would be $2200ish plus shipping, so around $2300ish.   RH has a 2020 price PDF file on their website you can look at, you want the pre VAT prices if your in the USA.

       I can see your string bikini. 

      I did the vid last week before the snow.  

      I can see the pull string !

    • Man I like that! I really like the silver smokebox with red roof version!! what is the street price on these?

    • Awsome video Shawn, just goes to show that Roundhouse's quality and and running is second to nobody. Says something for keeping chosen models around their proven gas firing system, standardized cylinders with one of their 3 valve gears, inside, outside or slip eccentric on the basic series.  Mike

    • I had the opportunity to test out the new Davenport with Jay Kovac from the Train Dept. All I can say is wow.  Ran great even in the cold weather.

    • If any of you have an Aster Reno I need the measurement of it from tip to tip including tender.  If you could do that and let me know please.  I have one in kit form and haven't built it yet but need to order a David Leech carrier.

      Yours in the Hobby
