Re: nuts and bolts in scale

With most of the model hex nuts and bolts being scaled down from the standard sizes of hex nuts and bolts, the appearance is OK for most but not all models. What many do not realize is the major locomotive builders for years used only heavy or extra heavy hex nuts and bolts from one end of a steamer...

Re: Kudos to Eccentric Engineer

It seems that injectors were custom builds at the factory long ago. Some guy had a rack full of parts and hand picked the parts that best fit together when building up a new injector. I thought the custom fit situation was just with Nathan Monitor style injectors. Now I find that Anthony has reveale...

Re: Spindle bearing replacement

Bearings can always be interesting as they slowly wear out. Long ago a friend had a well used lathe that had developed a slight chatter in the turned finish of parts. He tried all possible methods to resolve the chatter and decided that the spindle bearings were suspect. He purchased new spindle bea...

Re: odd threads

A century ago, threads were still not standardized real well. Many companies developed and used proprietary threads just insure you bought their parts if you needed spares for repairs. The singer sewing machine company was notorious for such activity. The Nathan Manufacturing Co often included some ...

Re: Wooden boxcar door track?

The sliding doors of many box cars and even passenger baggage cars were hung from above with what was called a door trolley on a railing. The bottom of the door was usually riding in a guide bar with perhaps what was called a slide to help stabilize the door during movement. Most of the baggage car ...

Re: Darkening / "bluing" brass?

I work with brass and bronze all of the time at the local railroad museum. Sure, the new fresh turned metal looks nice but the curator likes to see the patina of age on new parts. I now use sulfurized cutting oil during the final turning and finish work of the parts in bronze and brass. It is like m...

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. ...
