Re: Rectangular cotter holes

Forgot to mention that in working on a 1922 Baldwin steamer recently, I found use of hairpin cotters. We removed the pilot truck grease cellars for cleaning and inspection. Two long 1/2 inch diameter pins secured the grease cellars. Security was provided by hairpin cotters in perfect formed rectangu...

Re: Rectangular cotter holes

Nice work on recreation of the rectangular holes for the hairpin cotters. Never an easy task in full size. Long ago I saw an unfinished model live steamer in 1.5 scale that had some incredible craftsmanship up until the original builder passed on. One of the most stunning achievements was scale hair...

Re: Quieting noisy gears

Can you make a nice looking cover for the gears and submerge them in a light grease?

Re: Book about precision

I recently was loaned a copy of the Moore book and wish I had seen such information long ago when I was starting into precision machine work. It was very enlightening and has made me look at my machine tools with a whole new respect for what they were designed to do. Upon returning the book to the o...

Re: Franklin C-1 booster

Would be interesting to see some 1.6 scale booster drawings with dimensions to see just what size of materials or castings would be needed. Have considered making one before the boiler is attached to the frame. Far easier to deal with the booster at this time that working around a firebox. Wonder if...

Re: Are dynamos too noisy?

If your exhaust is not that loud, the added noise of a working turbo can cancel out the stack noise real well. Worse is the saturated steam from the turbo will be right there in your face worse than the exhaust from the stack. If wearing glasses, you will soon be in a miniature traveling fog cloud. ...

Re: Sourcing pig iron

Engine blocks and heads are heavy and tough to break up. Even with a big hammer they resist your efforts but will save a trip to the gym. Better to look for smaller items of cast iron to begin with. Internal combustion engine crankshafts, cam shafts are much more easy to work with. A friend discover...

Re: East Coast Locomotive Works

I was considering a purchase of some tender trucks from the owner when the business was Klamath Locomotive Works in CA. Suddenly the father passed on and castings/materials were suddenly hard to get from the foundry for some unknown reason. The son acted like he was going to keep the business going ...

Re: How to fixture a stack casting?

Stack castings are one of the more difficult castings to deal with as there are no flat surfaces to take advantage of during the holding of the stack. Seems like I have done more than a few stack castings in the past and each one presented different problems. One time the stack was wrapped in some s...

Coles Models Holt 75 engine model

Long ago Cole's Power Models offered prints and a casting set for the Holt 75 motor. I considered building the model more than once but never did. A friend bought the casting set but was not a machinist. He had a machinist begin working on the castings, but the parts were never completed and returne...

Re: What Engine Is This

Placement of the pumps on the front of the smoke box not only gave a more massive appearance to the front end, but also served other real engineering purposes. One was to get more weight on the front end of an articulated locomotive which often suffered from less than perfect weight distribution cau...

Re: 1.6” Scale “LEACH” Sander Fittings

That is a U S Metallic Packing Co. sander valve which Baldwin used extensively on shortline and logging locomotives. They were also known as King Sanders from what I have seen.
