there are a few thing (trucks and engine) you can use from Kozo's book, the loco your building is quite different boiler, mainframe and cab then the one in the book. Kozo's dos a good job get you up 1 1/2 " scale getting to 2 1/2 your on your own. Any pitfalls I can think of wound not apply to the 18 ton loco

I am about to pull the trigger on building the A3 in 1.5 scale. I've been building some small-scale model engines for a couple of years, and am planning to join a local live-steam club.
My shop equipment:
Bridgeport manual mill Monarch 10EE 12.4x20 lathe (1942 round dial) Novakon NM200 CNC mill Johnson horizontal bandsaw 10" pedestal grinder
I also have access to equipment at a nearby votech school where I'm taking courses at night. I can use both the Haas CNC lathe ad mill, there as well as mastercam for CADCAM.
My first parts will be the frame.
I am wondering if anyone has finished the tender in 1.5. Assuming that one would ride on it, it seems that it would need to be beefed up to support more weight. Also the shape seems ill-suited for riding. I'm thinking that a more "standard" tender makes more sense.
If anyone has 2D CAD drawings to share in DXF or DWG format I'd love to get them.

Hey guys, I joined this forum four years ago now. Didn't even think it'd still be around. Well, I dusted off the Pennsylvania A3 switcher book, and that'll hopefully be my school project for the next few years. I'll send pictures and such, which all depends on certain parameters of my university.
It's good to be back in the shop!

I am new to this group and also live steam. I think for me it is more the building than the running.
I have the books for the Climax and the Heisler and I am curious why there are hardly any threads on either of these engines. Is there something in building them that is unpopular?
Cheers,
Tom

Hello Tom,
Welcome to the group. One thing to consider is the age of the Climax and Heisler plans which predate digital cameras and widespread internet use. Anyone coming along nowadays is likely to start with the A3 since those plans include a lot more teaching. That was my own history. So you see a lot more activity with the A3. There are also a few minor issues with the older plans such as the use of packing instead of o-rings. A person with experience from the A3 is more confident in making design changes for o-rings. For US builders, the metric scale of the Climax and the gear fabrication may be discouraging.
Best Regards, Ed

Thanks for the reply and explanation Ed. That is sort of what I thought was happening. It is hard to get my head around the fact that these plans have been around for a long time.
Can you tell me if the A3 is in imperial measure or is it metric as well?
I did find the pics of your Heisler as well as your others. Very Well Done!!
Cheers,
Tom

Hi Tom. The A3 book is all imperial measurements.

Thanks Todd,
I will think about getting that one as well.
For the moment my favorite is the Heisler ... mainly for the v style motor... maybe I will just do a 1"scale motor mounted on some stub frames.
Cheers,
Tom

I'm building a 3/4 scale Pennsy and have come to the conclusion if you build to print you better have lots of money!!! A Sievert torch for $220, brass like it was laying on the roadside and enough different sizes to confound US Steel. Enough different screws to make any fastener co. jump for joy. Taps like you could buy them in a 5cent candy store. I like the book , but no list of materials ( for obvious reasons) , part #'s used over and over. I finally used the page # to save a little time. Change the 3-48's to 4-40 cause it's a lot more common. Make a pattern for the drive wheels and send them to a foundry? More money than I got. Guess I'm just an old grouch but that book was not written with thrift in mind. This oughta wake somebody up!!! dickr. My Heisler in 1 1/2 scale used a lot of scrap metal and only a map gas torch for $30.00. There are ways around spending a lot of money. Also spread out over 7 year build makes it easier on the wallet
