After the opinionated exchanges regarding the operation of lubricators, everybody's afraid of giving their opinions on this matter. : ) How about 3/32" tubing to buy a little more cross-section area? 3/32 scales out to 1.8" OD at 16mm/ft and 1.9" at 15mm/ft. Thanks for addressing my question, Steve. I'm going to try the 1/16" od in brass and see if it works. If not, I'll go to 3/32" od. I think that I'm going to experiment with placement too. Above, below, and even with steam line to see if affects delivery rate. I'm also going to try running steam thru the line without the pulsation of oscillating cylinders to see if that has anything to do with the feed rate. Maybe generate some facts about the operation of lubricators. Since the lubricator/chassis is not connected to the boiler, it would be fairly easy to try different configurations at this time. royce in SB

U.S. Army 0-6-0 tender engines, and the Westinghouse Cross Compound air compressor was located on the smokebox door! The access door to the interior, was off center, and the compressor was mounted right to the smoke box ring, off center in the other direction. This was done to keep the locomotive somewhat more balanced, weight wise. When the compressor is mounted on one side, you have a pretty noticable extra amount of weight on one side!

Re: dead leg piping
Actually, mounting air pumps on the front of locos was surprisingly standard practice for a number of railroads. Many standard gauge locos had them mounted on the front pilot, right in front of the smokebox. Some hid them with sheilds, some left them right out in the open. On the narrow gauge side of things, the D&RG K-28 locos had the airpumps mounted on the front of the smokebox. It was one of the characteristic features of those locos. I wouldn't say it was very common, but it did happen in more instances to make it a normal practice, rather than an anomoly. Later, K

Keith Taylor wrote: - Royce, Bending is easy! Keith Again, quick, elegant answers. Thanks for sharing these good ideas. I've heard them before, but they just didn't come to mind when I thought of .060 tubing with .015 walls. But you're right. I'm sure any of your approaches will work wonderfully. Thanks. royce in SB PS I was able to steam my Philly boiler last weekend and connected the throttle outlet to some tubing which I connected to the chassis. It ran on steam for the first time ! But this was without a lubricator, hence my current efforts to resolve these issues.

If the middle of the tube is filled with a low temp melting point substance, it won't collapse or kink. On big tubes, I've even had luck filling the pipe with sand! (weeny little tubing, however would require some awfully fine sand!) Also, making a "bending" tool is easier than it sounds. If you make a "form" by turning a button of the same radius as the bend, with a groove that the tubing will fit down in, and a movable piece, or "arm" that pivots on the axle in the center of the button, with a half round hole that lines up with the groove in the perifery of the button, secure the tubing and button, and sweep the arm with the tubing trapped between it and the button, and you will get a lovely bend with a repeatable radius. With a shop made tool, like that, you don't even need to fill the tube with solder. The tubing benders used by refrigeration folks are great, but I don't think you have much luck finding one as small as you'll need. Or of the exact radius you want. So, a shop made one is best, and can be made from hardwood if that's what you have laying around! Keith

Not to change the subject, but I have a question. I'm designing a dead leg lubricator for my Philly. Can I make the pipe that goes to the steam tee out of 1/16" OD copper ? The ID is probably about .034 or so. I'm going to try and disquise the lubricator tank as an air compressor on the side of the boiler. So I'd prefer NOT to have 1/8" pipe coming out of it (would look way out of scale). Any thoughts ? royce in SB

As these are usually on the side of the smokebox (at least on this side of the pond) could you not go straight through from inside the smokebox as per a similar idea and disguise on Regner locomotives Royce? -- Yours Aye Tag Gorton Longlands & Western Railway Trematon Office Saltash Cornwall Directors: T.
