Re: Tips for a newbie

Hi, But you can do that with 3 1/2" gauge! A Big Boy no, but a 4-4-0 or even larger is quite doable. Anything you can pick up by yourself is a good candidate for trunk transportation. Even a small 7 1/4 / 7 1/2" is going to weigh several hundred pounds, a big one can be several thousand pounds. Tom ...

Re: Union Pacific Big Boy in 3/4 Inch Scale

Hi, After I posted the last four pictures, I noticed there was a horizontal yellowish band along the side of the boiler. There really is nothing there, its just a reflection on the paint of the yellow lift table the engine and stand sit on. Its a long, slow road and there is still a lot left to do, ...

Re: Union Pacific Big Boy in 3/4 Inch Scale

Hi, Here are two more pictures showing the cladding as far back as the cab. The first shows the second sand dome, the dome in front of the cab, and the front of the cab. still further along(a).jpg The second shows the dome in front of the cab and the cab itself. Gerhardt made the cab and the domes, ...

Re: Union Pacific Big Boy in 3/4 Inch Scale

Hi, Here are some more pictures showing the boiler cladding in place. The front wrapping is permanently installed together with the dome cover. The front sand dome is in position but the #0-80 bolts that hold it aren't in place yet. At the start of the cladding, you can see the 1/8" tubing for the b...

Re: Union Pacific Big Boy in 3/4 Inch Scale

Hi, Some more progress on Big Boy. From something I saw on line, apparently 4005 was the only Big Boy that was wrecked. By mistake, someone threw a switch into a siding causing 4005 to derail and roll over. Just a bit of trivia that hasn't got lost yet. Since the last pictures, as you can see, I hav...

Re: Anyone else like to juggle between machines?

Hi shld, Two things. First, you say that the little mill you have is the biggest that you can lift the individual parts for so that is your size criterion. Don't let that limit your thinking. The Bridgeport I have ($2,800.00 at auction) came in the side door of the house in pieces and I assembled it...

Re: Anyone else like to juggle between machines?

Hi shld, To me, "good measuring equipment" is equipment that will give you an accurate measurement, but it isn't quite as simple as you might think. For some measurements, a scale is good enough, for other closer measurements a vernier might suffice, but if you are going to make a press fit, or a pr...

Re: Anyone else like to juggle between machines?

Hi shld, If I were you, I would stay away from control pedals on the floor. They are potentially dangerous. All you would have to do is step on one by mistake when you have your hands in the machine and "zip." This is one thing you have to keep uppermost in your mind; power equipment is inherently d...

Re: Anyone else like to juggle between machines?

Hi shld, Everything that's been said above is good advice and should be taken seriously. From the pictures, what you have is good enough to start with, but if you are serious about building, as Fred says, you need bigger, more accurate equipment and more space. For instance, my shop is in a room tha...

Re: Sherline CNC control problem

Hi Dan, I bought a turnkey Sherline CNC mill more than 10 years ago. The only thing I had to supply was a monitor. It was a very good value for the money, but it was a little small and light for what I wanted to do. I used it up until a few years ago, and then I built a bigger, heavier version using...

Re: Equalizing process and "faking-it-out"

Hi, An equalized system by itself with dummy springs is OK, but if you combine it with working springs, especially on our model tracks, a fully sprung suspension system works much better. While you can make dummy leaf springs with coil springs inside, there are two ways I know of making real working...

Re: Equalizing process and "faking-it-out"

Hi, The equalizing system shown in Mike Walsh's picture is fairly typical of equalizing systems (it is used in Big Boy) with minor variations. Equalizing is mainly a North American development. In Britain, springs were mounted under the individual axleboxes and that was generally good enough because...
