Re: Steam Turbine Question

Hi Phil, This is what I'm talking about. Turbine Wheela.jpg The jet hits the center of the wheel tangentially under the little "roof" that you see over each bucket pair. The roof guides the flow so it can't escape radially away from the wheel and the flow is split in two directions towards each side...

Re: Steam Turbine Question

Hi, One thing in my post isn't clear. When I used the word "balanced," I was referring to the flow of the jet against the turbine buckets, not the balancing of the wheel itself although that is also quite necessary. The bucket design should be symmetrical and the bucket should split the jet flow int...

Re: Steam Turbine Question

Hi Phil, You might get it to work, but the design is all wrong to have it work well at all on either air or steam. First, the impeller (turbine wheel) should never fit the housing tightly anywhere (this is true for both air and steam). Second, The inlet (steam or air) jet must be tangential to the t...

Re: From the ground up

Hi, It is possible to build a Big Boy from the ground up in quite a bit less than a decade, all you have to do is what Gerhardt did. It also means that you basically don't do anything else . When he was building the Big Boy, Gerhardt was retired from Chrysler and living by himself across the back ya...

Re: From the ground up

Hi, Just a small point. What you are referring to as a "train" is actually a locomotive. A train is a locomotive and (if steam) a tender plus one or more cars. One thing that no one has mentioned so far is the possibility of buying a locomotive from a club member so you have something to run and pla...

Re: From the ground up

Hi, One thing I forgot to mention. If you are thinking of buying a vertical mill from Acra, I would suggest you get one of their CNC units. You can use it as a manual machine to start out with and down the road, you also have the CNC capability. Check and see if the CNC control can be used as a read...

Re: From the ground up

Hi, The drawings on the CD's are the full scale drawings that have been scanned. If you want to, they can be printed full size and used just like the originals. As I said, those disks are probably the biggest bargain that you will ever run across! Union Pacific has invested a lot of time and money i...

Re: From the ground up

Hi, If you are considering a Big Boy or Challenger, go to the Union Pacific Historical Society website. There you can buy on a CD all the full size drawings to build either a Challenger or a Big Boy. Those CDs are one of the best bargains you will ever see anywhere. Also use Google to look up Tom Mi...

Re: From the ground up

Hi comebackshane, For the full size mill, do you mean Acra instead pf Arca? I looked at the Acra website and their machines are quite impressive, especially when you see they are 2 axis CNC. Even the smallest of them would be more than big enough for your purpose. I have been doing this since the 19...

Re: FRUSTRATED with threading tubing

Hi Richard, All the replies are well worth listening to and each one helps. Using them all together will make a big difference. Threading, especially with dies places a lot of force on the work. When you combine that with trying to hold tubing in a three or even a four jaw chuck, it's a recipe for f...

Re: Jesse Livingston

Hi, I'm sorry to hear that. Although he hasn't been active on chaski for quite some time, I'm sure many will miss his comments. I know I for one always appreciated his ideas and replies. They were always informative and well worth considering. He was always polite, humorous and kind. Richard Trounce.

Re: Trains in Ireland? Priorities in London?

Hi, Try and hit the Science Museum in South Kensington on a day when they are running the corliss mill engine. It is easy to see that it is running on steam because you can feel the heat from the engine. Very impressive. For any mechanically minded person, that whole museum is well worth a visit. I'...
