Re: Handle for a Resistive Soldering Iron

I'm a junior studying to be an electrical engineer, so maybe by electrical skills are getting in the way of my practical thinking here, but here's my understanding of how a resistive solderer works. I thought the idea was to deliver as much current as possible to the workpiece, and make the workpiec...

Handle for a Resistive Soldering Iron

So I started to build a resistive soldering unit last summer, and got a 1000W transformer nice and rewound it to produce 3V (in theory it can output about 300A, but I doubt it can actually handle anywhere near that). Now the problem I am having is making a pencil tip handle. I have a piece of 1/4" b...

Re: Tools for a newbie

Thanks for the replies. When I said magnetic table, I was thinking something more along the lines of this. http://www.micromark.com/Magnetic-Gluing-Jig-10-1and4-Inch-Square,7038.html I have a cousin in sheet metal, so getting a piece of metal for use on the table isn't hard to come by. I was just wo...

Tools for a newbie

So I decided that even starting on a live steam engine now is not going to happen as I had to go another year without a job (and the shop I was working in had a management change). I got caught working on other projects ever time I was in there anyway. Anyway, I thought maybe I could try my hand at ...

Re: Southern Pacific P-8

Right after i posted last, the week went from enough time to work on trains to no time. Thanks for the diagram. I think the drivers should be close. My big problem is I have no feel for strengths of metals yet so I can not just decide on a good number like I can with wood. That picture is high enoug...

Re: Southern Pacific P-8

So I was going to make my drive wheel pattern today to see about getting them cast when foundry day rolls around at school soon. I realized something, though. I have no idea how thick to make the spokes and I haven't had any classes yet that taught me how to calculate such quantities. How thick are ...

Re: Southern Pacific P-8

Thanks. I knew the P-8s and P-10s were cosmetically almost identical. I wasn't sure about under the boiler. I plan to try to cast my own drivers. I was talking to the foundry guys at my school about it at the end of last year (yes they can do small steel casts). I can do wood working so I will proba...

Southern Pacific P-8

I finally found time to return to live steam after a few months of school ruling my life. I finally decided I would like to build a P-8 like 2467 or 2472. Does anyone know where I might be able to get the drawings for the P-8 class engines? I checked the SMU archives and didn't see it listed there. ...

Re: Cross slide casting

I don't think I could live with myself as a techie if I didn't ask about the Redhat box in the background. I don't come across to many other people in this hobby who are also computer geeks.

I only know of one industrial recycler close by. I went there once to get rid of some horrible sheet metal. Only the drive is allowed past the gate. No one gets in unless they are dropping off. I will look for more in the phone book.

Unfortunately, I don't know of any good junk yards near me. I have looked through the phone book and on line, and nothing. Every junk yard I have found is pretty much just cars. Does anyone know of a good junk yard near St. Louis I might have missed?

My anvil right now is a tie plate spiked to a tree stump. Very crude, but it does the job. I am in need of a better forge. I know I am going to get a lot of ash no matter what. My problem is I kept clogging the intake to my furnace with ash so I had to turn up the air to keep it clear. As soon as I ...
