Default 1/3 Case 65hp Steam Traction Model

Hi I am a 14 year old boy who is converting a Myers water pump into a stationary steam engine. The machinist who is helping me build the Steam chest, and D-valve. Has just gifted me a 1/3 Case 65hp Steam traction engine. This is a scratch built engine, started decades ago. The original builder passed away before it was finished. Looking for any advice on it. The boiler appears to be completed and it was pressure tested, crankshaft and eccentric are in place. No gearing, but running gear and steering is in place. No steam chest or cylinder on it. Any or all advice is appreciated. Thanks Johann

What's a score, congratulations on your acquisition.
Reduction engineering was selling the castings for the third scale.
There's a few build threads here on the stack to research through.

Can you give more detail? how thick is the boiler and fire box sheets ect and the dia of the main boiler tube ? can you give the dia's of the wheels? what sort of drive gearing does it look like was intended did you get any of it? I live in mpls and built my 1/3 scale.

Hi I have some additional details on the model Case, Boiler and firebox thickness is 1/4 inch, the diameter of the boiler itself is 8 5/8 inches, the Id of the flues is 0.80 inches, the diameter of the front wheel is 12 5/16 inches and the width is 3 1/2 inches, the diameter of the rear wheels is 19 5/16 inches and its width is 6 inches, and for the gearing their is no gearing what so ever and no clue as to what was intended. Thanks Johann

Default Re: 1/3 Case 65hp Steam traction model.

sounds like from the dimensions its a bit smaller than the standard 1/3 scale 65 There is a book out there some where its out of print but shows up on amazon and stuff by Ralph Andres that has sorta become the bible for this stuff you should get one the next routine might be to drag it to a steam show with a lot of models and people that know what they are talking about! they can look it over and make some guesses as to whether this is do-able I would suggest heritage park in Iowa in early june another would be some of the guys from rollag like Ray Wangler sometimes if you ask the full size guys about the scale its not well received Usually remarks about blowing up and killing every one ect.. The second and most important thing to do is go to steam school!! forest city has one in the spring and rollag has one around fathers day the schools fill out fast really fast so sign up NOW

Congratulations. Looks like a good starter project. I assume you have access to some equipment. I would suggest you get ahold of the book by Ralph Andre's on how to build a 3d scale Case steam engine. There is a wealth on information in there. Also Dave Hoover has a lot of old manuals on operating steam engines. Maybe take some classes in machinning if they are available to you. Get on YouTube and watch some of the machine shop videos. Kieth fenner has a ton of them on almost anything you could run into. Kieth Rucker is another. There are others. Most stalkers are more than happy to share their knowledge. Ask a lot of questions and post your progress on here. Good luck.

Great start to a lifetime of engineering ! If you drop down a few lines on this forum you'll see a picture of me with the boiler I built when I was your age. If don't have an academic goal now , start with a degree in engineering . I wish I had completed one.

Congratulations on your gift

With the dimensions given I would say it is around a 1/4 scale model in size
You will have lots of fun finishing the build and operating the engine when complete

Hello thanks to all who have responded to my thread. I have just received an early birthday gift from my parents, a copy of "How to Build a 4" Case Traction Engine and Water Wagon by Ralph W. Andres". After reading through this book it is obvious my engine was intended to be slightly larger then a 1/4 scale Case Engine. The book will be a big help with recalculation for the measurements of the engine. The Myers homemade steam engine project is also coming along nice. We have just finished the slide vale and steam chest, and now we are currently working on the linkage. Will post pictures soon.

Thanks to all-Johann

Hello to all who have responded so far to my thread. I would like to update on my other project of converting the Myers Water Pump into a steam engine. I have just finished the Slide Valve for the engine and I am now working on the linkage and Eccentric. If all goes well I should have a running engine by summer. Also I would like to use a similarly designed slide valve for the model Case Traction Engine. Here are some photos of the Slide Valve, and me machining it.

Thanks Johann

Hello to all yet again, and also thanks to all have responded to my thread so far. I am sorry but I was not able to respond for a while due to finals in school. Though I will now be able to start responding and working on the steam engines again.

I have been able to obtain a crankshaft from the machinist who has been helping me. It was a extremely awkward size though 13/16 inch, the nice thing is though that it is stainless steel. I have gotten the shaft drilled and countersinked, which means that I can put both eccentrics on, and start figuring out linkage for it. So then hopefully you will all be able to see updates on how the timing and linkage is. Which in turn will mean that you will be able to see a running steam engine.

Thanks Johann

Hello everybody to has responded to my form. I am happy to say that the Myers steam engine is running and, soon It will be getting refined and, being painted up. So that project will be getting wrapped up very soon.

So then I decided to take the Model Case out a couple of days ago and, pressure test it on the air compressor. Sadly to say though the flues are leaking on the fire box side and a couple are leaking on the smoke box side. But I have also noticed that some of the welds in the boiler arnt very good and will need to be redone in spots. But that's where my problem that I need all of you to help me with is. The actual inside of the fire box is only 9 by 8 inches so it gives me very little room to work with. So I would need to figure out a way to weld inside the fire box without damaging the boiler.

Thanks Johann

Are the flues welded in or expanded and beaded? How bad are the leaks

Your pictures aren't very clear but it almost looks like the flues are just sitting in there or weren't cut to be the same size. Also if they aren't welded in I suggest getting a flue roller and role them in don't weld them in.

Yes I agree with you that my pictures arnt very clear, but after disassembling the traction engine and tipping the boiler on its side I have discovered that the flues are rolled and not welded at all.
Also I have discovered my leaks in the boiler, the one in the smoke box was a drain that was not sealed correctly and, the ones in the firebox are 3-4 flues that have not been rolled.
So this leaves me at a questionable spot where would I get a flue-pipe roller?

Thanks Johann

Ebay. Care needs to be taken not to over roll the tubes. Just eniugh to stop the leaking. Boiler tubes are measures at the outside diameter. Be sure to get the right sized tube roller. A local steam club might be a good source for a loaner. Shouldn't be a problem using them inside the firebox. When you fire the boiler take care that the draft isn't hitting the flues with cold air. That can cause them to leak which may be what has happened.
