That a great start Dale...more than just a start really.  With your permission, I would like to move this to the Vehicles category which is where most of the loco threads are shown.

Dale, what scale is this engine. From the pictures it looks bigger than most of Kozo's engines but can't be sure. Just thought you were scaling it up perhaps. Nice looking parts BTW !

Hi Dale

Very nice Project!!!   :cheers:

I really like the K-27, and have been looking for plans in the net. But, I didn't find any.  :ShakeHead:

Where did you get yours?

Dale, (and others) I have a build thread over on the Chaski board, showing my and two other builders progress on the K-27... There are a lot of ideas being tossed around over there, and I just thought it might be helpful for anyone here who's interested in building one...

Title: Re: Dale's k 27 By Kozo
Post by: johnhudak on February 03, 2014, 06:56:43 PM

Dale, Are you aware that Kozo extended the front end of the loco...? He did this to allow a carrying bar to affix to the front end, so as to allow for easier transporting of the engine.. It's also why those two holes are in the rear frame, for a bar to fit through. Anyway, Myself and others are going to be shortening up the front end back to the prototypical dimension. As far as we can tell, it needs to be shortened by about 13/16"
I don't know if this matters to you or not, but it looks a little odd when looking at the side elevation drawing that was in the July/August issue...
John

Post by: TerryWerm on February 08, 2014, 08:07:48 PM
Are you planning to install steel tires on those cast brass wheels??  I would think that brass would be a bit too soft to last for any length of time when used as a driver.

Hi Dale,

In the early days thus it was. However since then we have broadened the forums scope and we welcome your loco build.

Best of all you have posted it in the correct board within our forum.

I hope that clears it up for you.

Why not make them proper
Spring steel is the way to go you can buy it in the soft sate drill and form it as you like assemble with the clip harden out fully and let down to blue .

Just do not drop em when fully hard they are like glass

D. H sell it in coils the correct width and soft. ,usual disclaimer

For my A3, which is approximately the same weight as your K27 will be (depending on boiler construction), there are 4 spring packs of 1/2" wide spring steel, 6 leafs each.  The steel is pretty hard, but I had no trouble machining it with carbide tooling.  Since the K27 has many more packs, I wonder that they are more for looks than for actual suspension.

Title: Re: Dale's k 27 By Kozo
Post by: paul gough on December 01, 2015, 08:51:58 AM
Greetings Dale, I have a question regarding the piston valves which I hope you (or anyone) can shed some light on. I note Kozo's article in Live Steam (July/August) specifies 0.04 mm.,( 1 thou), for the clearance and advises thermal expansion will enable an adequate seal with minimal leakage. My question is, do you consider this close tolerance combined with expansion of the valve set up a 'molecular seal'? By this I mean the seal is brought about by the very thin film of water/oil on the surface of the valve head and wall of the valve chamber. I remember reading about molecular sealing somewhere but have forgotten where. I thought this design might be taking advantage of it and would be very interested in how effective it is. I do not have any of Kozo's books on other engines to help clarify his ideas further. There might be value for me here in overcoming the sealing issues relating to the disk engine I have some interest in. Regards Paul Gough.
Title: Re: Dale's k 27 By Kozo
Post by: dalem9 on December 01, 2015, 01:19:01 PM
Hi Paul, Kozo says that there is going to be a small leakage of steam. I tried to check to see how much leakage there was and did not notice any . I was only using about 10 # of air pressure . Now that may change when run on steam . I took a lot of care to get the clearance close in the valve . It may change when things get hot . I am not sure that under higher pressures if the seal will be as good . If you think about it there is very little time that the steam has to leak on each cycle . We will see . Hope this helps . Dale

Thank you for your comments Dale. It will be interesting indeed to see what results are obtained with steam and the use of this close tolerance. Please let us know how things go when you get to that point. Regards Paul Gough.

Oh - those must have been a drag to solder on the chimney.

I can only imagine making a jig from stainless to hold them in place while soldering and using a "dam" to keep the older in place.
Why stainless - well it got a low heat transfer characteristic for a metal.

Hi Dale,
 Found it!
Its not my desgin...it was in the ME about the time of the series on the loco build. The idea being that it helps clear the gases from the top of the smoke box...cant say one way or the other but the guy who came up with the idea said it improved locos that it was fitted too. My sure is a free steamer

I recently converted my mill to run under PathPilot, and I like it more than Mach3.  However it requires TTS tool holders to run as intended.  Since I didn't care to spend the $ to acquire these, I need to stop the program at every tool change so that I can zero Z.  At that point I restart the program manually at the tool change line.  Other than that, I'm happy with the changeover, and can get faster rapids (now running 120ipm vs 75 previously).

Title: Re: Dale's k 27 By Kozo
Post by: Kim on October 27, 2018, 05:24:40 PM
Isn't the K-27 a narrow gauge? So, even though its designed for a 3.5" gauge track, I believe the scale is bigger than his other engines.  I think its 1.17" or something like that.

Or maybe you're modifying Kozo's plans and making it a little smaller?

Regardless, that is some mighty fine looking brass domes, Dale!
Kim
Title: Re: Dale's k 27 By Kozo
Post by: dalem9 on October 28, 2018, 01:56:50 AM
Kim no modifying It is built to Kozo plans .The loco. is about 12 iniches wide by about 40 inches long . Yes the K27 is a narrow gauge . It is larger then the other as you say . Kozo has done a great job at disigning it I thanks anyway . I have all his books and have learn so much from him .
Title: Re: Dale's k 27 By Kozo
Post by: kvom on October 28, 2018, 10:30:22 AM
Being a narrow gauge, scaling to a given track gauge means a larger engine than standard gauge.  One of the fellows at my club has a 7.5" gauge D27, and it's over 1000 pounds.

Beautiful work. I can believe it was a job getting the door to door fit as good as it looks. Well done!

For the most part, fire doors have openings to allow the engineer to see how the fire is doing.  Most air flow is up through the grate.

On the original cast iron fire doors the holes may have been used as part of the core sand. The door would have been hollow, cored with a flat plate shaped sand core, and several round posts and possibly some cast in chaplets on the top of the core would be needed to hold it in place while the iron flowed around it. The round posts would leave the holes after casting. After casting the sand core would be poked out through the holes.  In use, the holes would vent cab air to the hollow in each door to help insulate it a bit by making an air gap between inner and back walls of the door. If the door were solid, the inner face would radiate a LOT of heat into the cab. You would not want to brush up against a red hot fire door while running the engine!

Well, I fired my loco... Good and bad, everything worked good. The cyl. leaked a lot though, through the solder joints, I think I will put a sleave in the passages from the valves to the cyl. All in all not to bad.More work for this winter!
