I like it. Its a good idea. I enjoy seeing engines run at idle. Treat it like a gas turbine, don't stand in plane with the rotation of the prop and you'll be fine. You could also turn a spinner (which can be quite large on some aircraft) out of brass and gain a lot of rotating weight if you wanted.

Sweet! Congratulations! I loved seeing it run slower in reverse! You can see all the rods and links doing their job! Well done!

Awesome! Looking good! I'm still working on my 3/4" A3 but I'm way behind you. I hope you get lots of video of your loco because there is a serious shortage for how popular the Kozo A3 is. Youtube has maybe 3 videos that I know of where you can see it running. 2 on test stands and 1 on track...

I know. I'm seriously considering using steel. After shinning up the whistle and bell I thought no way will I want to paint this. It's not to late for me to use steel. I didn't buy the larger diameters yet for the smoke stack and steam dome etc.

Well, I started the Kozo A3. So far so good. I started this project after I got discouraged with a design of another locomotive I had been working on for months that over half the data was lost and the backup copy didn't function. Anyway I was dying to start machining some parts. I started 2...

I'm having trouble locating any ground stainless steel in smaller sizes less than .25". Drill rod has lots of ground sizes obviously but its not stainless.

Hello, I'm building a KOZO A3. I'm ordering metals from speedy metals and online metals. (Neither carry all I need to place one order). The plans call for phosphor bronze, only online metals have phosphor bronze, but they carry C510 and C544. Which one? Also I wanted to pick ground stock for...

Does anyone know where AND what cutting tools I could get for my 7x12 lathe. I need a good turning tool, parting, and cutoff tooling. I don't have a QC tool post, I don't really need one at the moment. I've had ok success with HSS that I've ground, but a while back I tried to turn some free...

I did get to the bottom of the green sand problem. I put some wet sand on a metal plate and let it dry. Then I wiped away the sand hoping I'd see the clay still stuck to the metal. It had a very faint haze on it. I figured that it did contain clay but very little. I separated about 5 lbs of sand...

Hello, I have a question regarding green sand. I ordered 30lbs of premixed sand off ebay. I wanted to do it myself but I couldn't source a fine enough sand or bentonite clay. Plus it was convenient and saved me time. I got the sand and they also included extra bentonite to "refresh" the sand...

You had the pleasure of riding in a Baldwin 2-8-2 Mikado! Dollywood operates two Baldwin Mikes (this season will be the first time they will have 3 Baldwin Mikes running!!!!) and its highly possible it was the 190 Class number 192 "Klondike Katie." All Dollywood's engines are from the White Pass...

Lol! I started a post in the "Work In Progress" section of the forum. My locomotive progress. http://www.homemodelenginemachinist.com/index.php?topic=8109.0

This is my scratch design and build. I'm sure progress won't be very fast, but I'll update as often as I can. Side View - Working out Walchaerts valve gear. Top Down View - Getting the running gear and cylinder alignments setup. Pattern for wheels - Probably a practice pattern...

Walschaerts had many advantages over the Stephenson. One of the big reasons was weight. Walschaerts moving and rotating mass was almost half of the Stephenson. This in turn improved performance and wear. Also adjusting and accessibility was much easier as the gear was accessible from outside the...

I've had difficulty looking for an exact answer for respiratory protection for what we do. It appears that typically a N95 Filter is sufficient for most metal fumes. 3M also suggest this. But it really depends on the concentration of what your trying to protect yourself from is the determining...

Hello, everyone one! My name is Justin or Fuelrush. I live in East Tennessee at the foot of the Great Smoky Mountains (which I love dearly). I work as a machinist and tool and die maintenance. I love working with metal and making things. As far as engines, I've started a build of a Jet Turbine...

Hello, I wanted to know what (if any) safety precautions everyone takes when casting brass. My main concern was to avoid inhalation of zinc oxide fumes from brass. I've read many safety post and sites regarding home metal casting and haven't seen any mention of anyone wearing a respirator for...
