Re: Need Air brake line Gauge with two needles

For those interested- more recently the Live Steam May/June 2019 has Kozo's DIY pressure gauge for the K-27 project. Or it would be included in volume 2 of the K-27 books to be coming out next year. It is a 1-1/4" diameter bourdon tube type and he details making a dead weight tester for calibra...

Re: There are railroads and then there is this....

What a gorgeous ride! I thought this was interesting looking for what the original steam locos looked like for the many years prior to electrification. They used a transverse mounted boiler to cope with the grade- different from the Mount Washington. There are a couple photos that give a hint of the...

Re: Wide Wheel Treads

From Wikipedia - Ecuadoran Railways northern line from Quito to San Lorenzo on the coast ran through Alto Tambo. 3'-6" gauge which looks possible from the video. Quite a creative way to use the abandoned right of way!

Re: X3 Mill tramming thoughts

Hi Jimmy, I have the same mill, and just reading this thread today- was going to suggest lapping the gib, so I'm glad you found that! I had the same issue with movement of the head when I got it new, and improving the fit of the parts resolved enough of the issues that the machine continues to do a ...

Re: Kozo A3 3/4 scale up and running sort of

Hi Jack,
The St. Croix track is 800 and some feet around. I can go a full lap on one firing if the load is light or holding the camera ;)
Better is to give it three shovels at the halfway past the curved bridge before the long 1% upgrade, and again back at the station before the downgrade.

Re: Firetube Boiler Project - Leak Troubles

Hi Quinn, Sorry to hear of your struggles- I've also been following your boiler build videos- nice work! I completed my Kozo designed boiler for the K-27 locomotive last spring, and I built the A3 locomotive boiler a number of years ago. One trick he discusses that I DIDN'T do on the small boiler, b...

Re: Kozo A3 3/4 scale up and running sort of

Yes! We would love to have the 2.5" get used. There was a loco in the club- maybe a northern - but it is down with boiler woes and hasn't been seen for 10 years. We have 5" too for the European adjacent! ;)

Re: Kozo A3 3/4 scale up and running sort of

Thanks folks! I think the A3 is about a perfectly proportioned locomotive for its era, and I like the tank engine A3a even better. Al, I did the design changes myself - 'kit bashed Kozo' as a friend says- working from photos and drawings in a locomotive cyclopedia. Credit to Dave Sclavi for recommen...

Re: Kozo A3 3/4 scale up and running sort of

Looking at my A3 I'm seeing I did something different from the drawings. Per others recommendation I piped the hand pump to feed through the axle pump to enable pushing air through when starting up. Because the lower feed line is now under pressure, I made the hex portion with the ball seat larger t...

Re: Kozo A3 3/4 scale up and running sort of

Congrats on your A3! I have occasionally had water level bubbles in my A3, but in normal running the standard design works fine. I concur with others advice about it being a new boiler with small amounts of contaminants- steaming it a few times will help too. I blow down about a quarter of the glass...

Re: Future project: Pennsylvania A3 Switcher

I've been quite happy with my A3, though I did redesign it to be one of the saddle tank versions the PRR built. That adds a few pounds of tank and water for traction. It will pull two adults around the St.Croix track with a 1% ruling grade. To Bill's point on the throttle, I modified mine with the a...
