Hello everybody, I am building a Pennsy A3 using Kozo's book but I am scaling it up to 1-1/2, 7-1/4" gauge. I have set up a website to track my progress, check it out at the link below. I have been talking with Jim O'Connor for a while about trying to get this Kozo support group going. Thanks Jim for starting this forum. If anyone is building or has built an A3 in a larger scale please post here. I want to try to collect as much information and pictures as possible to help others who are working on similar projects. Hopefully this will evolve into a website dedicated to scaling up Kozo's engines. Thanks and please let me know if you are working on an A3.

Hi Jamie,
I'll be doing a "scale up job" on the A3 as well, but 7.5 gauge. (west coast)
I'll be headed to my local steel supply store on friday, and as this is my first locomotive I suspect I make more than a few trips.

Hey Brook, that is really cool. I am just getting started as you may have seen on my progress website. I'd like to work together alittle and share ideas if you want to. That is the whole purpose of this forum.
Currently I am wondering how to install bearings in my tender trucks. I know basically how to do it but I need to figure some things out first. Any help here is appreciated.

Hello Jamie,
Like what you've started and await the first installment on the actual locomotive itself.I say this because I have been building a tender for an 0-6-0 for some time that I think would work well and fit right in behind the locy.It's not a slope back style but is characteristic of switch engine tenders from that era.I used arch bar trucks and made a bending jig found in an old live steam magazine, by Maynard the fellow who came out with the Clishay.I've used commercial wheel castings and transverse leave springs from railway supply co.My main frame is welded together and uses small channel iron and flatbar as per standard prototype practise.I will put rivet detail only where it shows etc.I'm going with bushings in the trucks ,as I had them and if they don't work out they can be changed at a later date.My tank is being made out of metal salvaged from an old welder gastank and reinforced with copper angle iron ,that I make up out of salvaged copper sheet.I am solderig and doing the rivet rows as I go and will have this very time consuming part mostly finished in componant style eg. rear two sides ,left and right front and rear of coal space etc plus top and bottom.Ive toyed with the idea of building the A-3 instead of the 0-6-0 that I had started since it would save time ,and allow me to get up and running sooner.Ive always marvelled at Kozo's practical approach to building, often complicated assemblies as in his geared locies.I also always wondered why he never did any in 1.5 scale as it would have been well received here in N.A.Scaling up is not all that difficult but seeing Kozos approach to solving the larger problems would have made interesting reading.
My thoughts and thanks,
Dan W.Gledhill

Dan;
> I also always wondered why he never did any in 1.5 scale as it would have been well received here in N.A.
Maybe because: (in no particular order)
1) His appartment workshop, as described in one of his books, 8feet x 8 feet, would be too small to build one?
2) Bigger is not always better?
3) it's a lot easier to travel with smaller locomotives. (eg, you are Vancouver Island, right? I took my little TICH as carry on luggage to the VIME IBLS2000 meet, and had a ball pulling myself and another passenger with it)
4) 3-1/2" is a world-wide standard; I have seen Kozo locomotives when I was living in New Zealand, and The Netherlands.
5) After the "warm" welcome he recieved after publishing (gosh!) metric plans in an american publication, I'm surprised he even published anything there again!
6) It's easier to fabricate parts in a smaller scale?
7) It is about 1/8th the cost of materials for 3-1/2" as compared to 7-1/4", which makes it open to almost everyone?
I hate to say it, but after starting over 30 years ago with this hobby, Kozo has the scale thing exactly right, IMHO.
I do have castings for a Stourbridge Lion for 7-1/4" gauge, but believe me, if there was nothing smaller than 7-1/4" gauge, I'd be out of this hobby.

Hello John,
Thanks for your thoughts,and yes it's the Vancouver island guy.I have to agree with most of your arguments about Kozo.I too was quite dismayed when I first saw his Shay all in metric,even before we Canadians went that way.He finally came around when he designed the Heisler.I don't look at 1.5 scale as big when compared to trends toward todays 3inch and larger scaled engine,but where will it end?
Another thought that you didn't mention is that in Japan there may not be any 7.5 inch gauge tracks around due to Japan's limited space for such things.
I have Livesteam from it's first issue until the early nineties when I drifted away from the hobby.Today when i need a method or idea to fabricate a part I usually go to an earlier issue to see how Kozo would have done it.Maynard and especially Don Young also had simple and practical ways to do things .Kozo's ability to illustrate his ideas was some of the best stuff in LS to come along.

Hi Jamie I am also building a A3 Switcher using Kozo's book which was published in Japan and in Japanese ten years ago. (quitely same contents with English version) I visited your project web and I was much impressed. My building process(sorry in Japanese) can be seen at: members.jcom.home.ne.jp/tminagawa1/Tsuneo Minagawa Tokyo, Japan |

Hello Tsuneo, thank you for posting a link to your progress website. I plan to spend some time going through your photos, they are very impressive. I would like other people to see your site as well, it is a very good example of what we're trying to do here. Let's keep in touch.

Hi Tsuneo,
Your work on the tender looks great, I can't wait to see how your engine shapes up!

I agree, I finally got to look through all of your pictures. They are very good and they show what I have to look forward to. So what are you working on right now?

Hello friends
Thank you very much for your visiting my web site. From now I plan to insert English expression to my web partially.
As shown, tender and main frame have been completed. Next step is driving wheel. but supply of driving wheel casting will take a few months later. So I decided to skip some process i.e. engine and to start boiler making as suggested by Kozo. Readers of Kozo's book (only Japanese Edition) are given a benefit to be arranged to supply driving wheel casting from Kozo directly.
I am collecting materials and some tools for boiler making.

Hello Tsuneo,
Totally enjoyed your website and only wished i could read your complete captioning.The photos are though enough to see how you are doing it.I especially like those copper formed sides ,a method I will try in the future if i can find enough copper sheeting.What scale are you working to ,is it metric or 1.5 inch to the foot?What make is your lathe?
Many Thanks
Dan Gledhill

Hello dan
My loco's scale is 3-1'2" gauge. I'm using 7"x12" mini bench lathe, which is maybe an equivalent to catalogue No.G8688 of Grizzly.

You can "translate" Tsuneo's page by going to babelfish.altavista.com/ and entering members.jcom.home.ne.jp/tminagawa1/ in the "Translate a Web page" edit box. Then select "Japanese to English" in the drop down box and click on "Translate". It's not going to give you perfect english, but will at least give you a broken translation. By the way, Tsuneo's page and others linked from this forum, as well as the forum itself, are great. I have all of Kozo's books (at least the english ones) and have always been amazed at how little information there is on the web regarding his projects. This forum has already started to address that issue... -Sean |
