Boston & Albany K6b Pacific

Post by BobbyT » Mon Jun 09, 2014 6:16 pm

I am finally ready to start building a 1.5" scale, 7.5" gauge locomotive. I have been hesitant to take that first step but after reading many of the build logs here I have worked up the courage. Special thanks to Hudson Honey for being an inspiration. I am very fortunate to know some very accomplished live steam builders who are also very gracious teachers. Mr. Bob Dean and Mr Peter Bialecki are my mentors. Both of these fine gentlemen are avid live steam builders and master machinists. Now about my locomotive choice, I was fortunate to acquire various components and castings over the years which left me with:

* Bob Dean water jet Pacific frames.
* Little Engines rear cradle and Delta trailing truck castings
* Spokes driver castings
* Roger Goldman Baker valve gear
* Roger Goldman cylinder castings with Alligator style cross heads

Now this presented a bit of a dilemma. There really weren't that many Pacifics with the Delta-Spoked-Baker-Alligator combination. But then I stumbled on this beauty: Boston & Albany K6b pacific. These finally ended up on the P&LE at the end of their career.

The NYCSHS had the drawings for this which really makes life easier.

The cylinder casting I have came on a LE style built up frame. But since I already had the water jet cut frames I decided to make the switch. The primary reasoning is that each driver set can be removed individually if the need ever arises whereas the built-up frame is a lot more complicated.

First step was to true up the journal openings locate the cross head bracket mounts.

Fair Warning: I have been a train nut for over 40 years yet I still can't remember all the proper names of the parts so if terms like "thing-a-ma-bog" and "doohicky" offend you, then this is not the build log for you. :wink:

The next project was to work on the rear cradle. Clean up, square up and mill the end to fit the rear of the frame rails.

Here is Bob Dean doing the milling.

Bob and I were discussing the cradle angle. The LE cradle casting I have is fairly flat yet the prototype is at an angle. As we held in over the the drawing (which plot out to approx 1.55 scale) we noticed the prototype was designed differently altogether. So Bob Dean with great enthusiasm cut my cradle up and re-welded the aluminum.

another view:

It comes out of the main frame straight then angles up part way before leveling out again.

Sir,
I wish you the best of luck and I look forward to observing your progress on this build. Nice choice in Hudson's to model by the way, very beefy indeed.

Best Wishes,

Cradle mounted to frame.

I appreciate all the encouragement.
