Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

More catch-up from the holidays - I made these back in October.

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

There was interest expressed earlier with John's method for machining a radius end. Here is a video of John to further illustrate.

In addition, I put the boiler on the frame to get a look at what we have so far.

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

Wow- time flies! It has been several months since the last update. Progress definitely slowed down: SVLS pumpkin train, Fall Meet, International Railfair, trip to Bitter Creek & Western Railroad, SVLS Santa Train - you get the idea. The first picture is when took our frames out to the club during th...

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

I have heard it said that reaming Oilite bushing closes off the pores that make them work so well??? Recommended was pushing through a ball the correct size... I've never heard that - maybe it does. However, I don't have a ball that is .505" This is the same method I used to replace the bearings on...

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

As things go, there was a slight bind in the motion. John is studying the rotation to discover the source of the bind. ... As it turned out, the rear axle quartering was off .009" Would you please share more information? What was the setup to measure the error? I've heard of making an offset key. E...

Re: 15” ga live steam club feasibility

I've read in the past of a particular group that is in the northwest (Oregon? Washington? Not sure...) that built on their own privately owned land.... But if my memory serves me any good, I believe that some locals raised alarm and then the state came and punished them. What happened? They built b...

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

As promised, here are some pictures from the start of this project. John suggested I start with the boiler, because that is a part of a locomotive build that people sometimes get hung up on. I purchased the boiler tube on October 5th, 2002 for $30. All together I spend about $100 on materials for th...

Where did you get those wheel castings? They look nice, and different.
The wheels were cast at the Knight Foundry from patterns made by the late Don Juergenson for another build project about 25-30 years ago.

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

With the frames and rods done, it was time to put some parts together for a test fit. I had brought the wheel and axle sets that John and I made back in 2003-4. The bearing boxes were machined, but did require a little bit of file work to clean up. John is using the vise to hold a wheel set for fili...

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

Thanks for all the comments & encouragement. Yes, everyone can still count to 10! Moving on... With my homework completed, I was back to John's shop for another day of fun. The boys had cut open the pedestals using our bandsaw at home, so now we needed to machine them to spec. We started with machin...

Re: Father & Sons build project: Fitchburg Northern (2.5" scale, 7.5" gauge)

Climb milling the finish cut makes for a beautiful finish, but you've got to keep the locks tensioned up and feed carefully, or do it on a CNC:) When you were milling the radius on the rod end, was that sitting on a pin or bolted from the other side? Clamped down(can't see the whole part)? I'd be a...
