Hehe, scorching temperatures. I lived in New Zealand for a year in 1979, and I can remember on Christmas day we reached 25 degrees Celcius (roughly 75^F) They thought they were having a heat wave. Now Australia, that was a different matter...

Welcome to the world of the Hagerstown media! LOL
Yes, the loco is 202 and no more rolling stock has been added, just "repositioned".

I have a question regaring removing boiler studs. In the past I have just heated the shell of the boiler and wrenched them out. Usually they come out and no damage to the threads and the hole is reusable. Knowing a little bit about heat treating and a fair amount about welding (code and non code welding}I feel there is no danger in this method. After all the heat from welding is much more intense then heating up with a torch. So the question is, "is this way of removing studs acceptable or not". I do not quench the shell with water or anything. I would appreciate and knowledgable comments from experienced boiler people. Thanks, John

I don't claim to be knowledgable or experienced but what you are doing works for me. I heat the area around the stud then stick a ice cube on the stud. This seems to make the job a lot easier and doesn't take as much heat on the shell.

You can drill through a busted off stud and heat it up, then squirt water down the hole to shrink it out of its attatchment. Once it cools enough not to distemper a tool, use an easy out to remove the stub.

I have done it alot. However if its near a riveted seem or staybolt I heat yhe stud red hot and let it cool off, no quench. You can also put some kroal on it when worm and wait for it to work . Say 10 min. or so. Most of the time that will work. bb

If you want to remove a rusted nut from a rusted stud, historically the process is to heat the nut, it expands, breaks loose the interlocking rust in the threads and the nut backs off easily.
Now, examine the geometry of a stud in a boiler shell. What is the purpose of heating the shell around the stud? Does the stud hole in the shell expand? Nay verily! The heated metal has to expand but it is surrounded by cold non moving shell metal. The metal around the stud will collapse on the stud, crushing the interlocking rust, allowing the stud to be removed. Is the boiler damaged. Probably not.
However, if the stud is to be removed, it usually is to be replaced. If you want to save a ton of BTU's, just heat the stud up as hot as you want.
This expands the stud in the hole, crushes the rust and after cooling, allows for easy removal. Quenching or not quenching the stud makes no difference, as the stud is expendable.
Heating the stud method is especially useful in removing studs from cast iron cylinder castings, unless you enjoy the "drill the broken stud and use an easy-out method."

The Ohio Central Steam Department will open its doors next weekend for a “Volunteer Blitz Weekend.” The exciting weekend begins on April 8, 2004 at 8:00 a.m. and will run three days ending on the 10th. During the event, volunteers will work on steam locomotive No. 33 currently under restoration as well as Northern No. 6325. A variety of other projects will also be completed during the event.

Becoming a volunteer on the Ohio Central is simple. You can begin by attending the “Blitz Week" activity or you can respond to this note via e-mail. You may also learn more about our program by visiting our web page at ocsteam.com. As our program is growing and changing, we are finding ourselves in need of additional hands. If you have ever wanted to work on large steam engines, here is your chance!

The Ohio Central has a very packed summer schedule. Our largest event, Train Festival 2004 (trainfestival2004.com) is shaping up to be the steam event of the year.

If you would like more information about the “Blitz Week” event, please call me at
740-622-8118, Monday-Friday 7-3:30 Eastern Time or by e-mail at jerimmasch@ohiocentral.com .

If you are planning on attending, please advise us as soon as possible as we are planning on feeding all volunteers during the event. We would hate to not have enough food. Not only will we have plenty to eat, we will also have a number of fun activities such as slide shows and video shows.

See you next week,

John E. Rimmasch
