Numbers assigned to different wall thicknesses of pipe (e.g. sch 40). I don't know how they were derived.
Nor do I know what the thickness for a given schedule is or if it can be calculated with some formula or anything. But that info may be available in plumbing books somewhere.
Bigger number means thicker wall I believe (been a while since I've handled much plumbing materails).

Working on Kozo's Pennsy A3 in 3/4". I have about 600 hours of work in it and have the tender done and the valve gear is just about complete on the loco. You can see some pics of it on Dan Kautz's page at thms.tedatum.com/BBoard/Sigler01.html

Siggy why are you building A3? I thought it was just for the begginers like me. You are a magician. Really nice work. Take care. Vic Smaggovic

Jamie, I am getting ready to build the A3 at 3/4" scale. So far I am getting material (wheel castins) and so on. Take care. Vic

Vic,
If only it were as easy and quick as the video makes it appear. Actually, that would take all the fun out of it...

Siggy: Very nice. The running gear, cylinders and drivers look beautiful. The time lapse video really helps show how the tender pieces come together and in what order. It must be exciting to have some of the motion working. I started on some A3 wheels in a friend's machine shop and will be getting more space for my own shop starting this Saturday. A small lathe will be coming first sometime in July, and milling machine to follow. In the mean time, here is some more inspiration for everyone, impromteau videos I took at the Joshua Tree & Southern fall meet last year. Lots of great engines running and puffing up their grades! (no A3 however, but there is a beautiful 7 1/2" gauge Shay in the second video, not sure of what origins) www.mojaveserver.info/vids/www.mojaveserver.info/vids/joshua-tree-&-southern_part-1-480x360.wmvwww.mojaveserver.info/vids/joshua-tree-&-southern_part-2-480x360.wmvwww.mojaveserver.info/vids/joshua-tree-&-southern_part-3-480x360.wmv (broadband highly reccomended, Windows Media Player required) First video is general running, second video features a Shay and the third video is a look at their fine gauge 1 garden railroad and progress on their 15" gauge setup. --Mike

Thanks for the vids, Mike. The first video will only play about 1:43 then causes Media Player to shut down due to corrup video format with error C00D11C5. Other two videos work fine. Not sure if I just have an outdated codec or what. I noticed that the file is coded with Windows Media 9, which shouldn't be a problem since I'm running WMP10. Oh well, very nice videos anyway.

Fixed it. The file was corrupted from an FTP RESUME operation. I re-uploaded it wholesale and now it appears to be fine. Enjoy!

I just completed the running gear on my A3 today and Dan Kautz has already posted some updated pictures on my visitors page on his site. You can check them out at thms.tedatum.com/BBoard/Sigler01.html . It took me 201 hours of labor to get the valve and reverse gear done. The loco now has a total of 475 hours labor to get to this point. I'm at 731 hours for the whole project (tender and loco). It purrs like a kitten on compressed air. Robert

Holy wow. Your photos make me not want to paint anything until it's all done. Just to see all that brass and steel put together and shining.
Where did you get the track it is resting on? Did you make it? I'm looking for a little display/test track that's preferrably not just some bar stock wedged into some ties.

I purchased the brass rail at my local hobby shop. It's standard LGB rail that comes in 1.5 meter lengths (LGB part number 10005). The brass was relatively expensive but they have it in aluminum too. I cut the ties out of cedar and stained them then spiked the rail to the ties using Micro Engineering large track spikes.

Ah - interesting that the smaller scale rail has enough clearance for our flanges. I'm still on the lookout for ready made 3 1/2" gauge track. In the mean time, I'll try out the LGB stuff for my display track.
