Happy 4th of July everyone!

Here are photos that I have collected since my last report.

We have completed and delivered the driving wheels for B&M #3713 to Steamtown, after weld repairing cracks in the wheel centers, replacing the main axle, turning the other journals, facing the hub plates, and quartering the crankpins.

Here, one of the hub plates is being faced in the wheel lathe.

We are also building a new fire box for #3713. She is equipped with an O'Conner firebox door hole, which has a curve built into the fire door hole before reversing direction to meet the backhead. The design claimed to result in less staybolt breakage and cracking in the door sheet.

To duplicate the needed shape, we had to make male and female dies, CNC milled from steel plate, and set up in our 600 ton press to press it into the door sheet.

Last winter, we reBabbitted some journal brasses for a customer. Here, one is being bored to size.

Old news, but here is the freshly Babbitted crosshead slipper for RGS #20.

We are also building a new firebox for a small locomotive.

We are making new eccentric cranks for a large locomotive. Here Paul is milling the split into the eccentric crank that allows it to be clamped onto the main crankpin.

Three new driving wheel sets for a customer are under construction at this time. Here are the wheel centers.

On our own equipment, our PRR bobber caboose is in the shop for a paint job. Anyone have the "correct" shade of PRR caboose red?

#475 is undergoing her 1,472 service day inspection. The UT survey found that the #1 boiler course had corroded to below minimum thickness around the sand dome, requiring a patch to be installed.

Here, the patch for the #1 course is welded out, and ready for x-ray.

Some sheet replacement is underway in the firebox as well. Two new side sheet patches and a patch at the top of the flue sheet are being replaced due to wear and tear (cracking).

This shot shows the water side of one of the side sheet sections that was removed. You can see the cracking that starts on the water side of the sheet, and works its way through to the fireside, appearing as a pinholes and leaking staybolts.

#475 is also getting one new wheel center, her original one suffering from a number of cracked spokes.

Here, the new wheel center is having the recess for the steel hub plate milled into the inside face.

Here, the new wheel has been pressed onto its axle, quartered, crankpin and tire applied, and Steve is attaching some additional counterweight to the wheel center.

Some switching required #475 to show her face outside the shop the other day. Sort of reminds me of a big sister to Little River #110.

Thanks to the forum for removing the limits on how many photos I can post. It streamlines the process.

Thanks Kelly! Love those N&W Mastadons. Too bad nobody has an SP 4-10-0 running.

Kelly, just great to watch a competent locomotive shop do things requiring great precision, correctly, the first time. Please keep up the fantastic work and share it here with the rest of us. Thank you!

I thoroughly enjoy your updates. There's some damned good looking machine work and welding there.

Well, actually acording to Whyte, 4-8-0's are "twelve wheelers". 4-10-0's are "Mastadons", and about as rare as well. Never the less, I agree that the N&W 4-8-0's are eye candy for steam fans, even though #475 can be a back breaking bitch to run in hot weather.

Kelly,

Caboose color..... I haven't had a chance to chase this all the way down yet. We have two cars that will eventually need paint.

If the cabin cars were painted the same color as the freight cars, I have the Munsell numbers from the PRRHTS on my list under Freight and MOW (see the sticky above) for PRR "freight car red". 1930s thru 1960s. The coatings manufacturer's color lab should be able to use those.

If you remember to, please let me know what you come up with and I'll add it to the list.

The story I was told was that PRR mixed their own paint, and of course had standard formulas for how much dry pigment to add to the base. In practice, the measured amounts were interpreted as however many handfuls of pigment per batch. If the painter had big hands the batch had more color or vise versa, i.e. there actually was no "standard". For what it's worth.

One more thing.... The chrome yellow for safety appliances usually matches closely to National School Bus Yellow. There's a Fed Standard fo that. I have not yet verified that for PRR but it gives you a point of reference as to what approximate shade of yellow they should be.

You are correct that PRR bought premixed pigment in bulk. Hence, batches could change slightly in color and sheen depending on who mixed the paint that day so in reality, there's no such thing as a perfect match. I have PRR mixing instructions that I copped online somewhere. Not useful today but interesting.

Great photo of an engineer in the cab of the N&W Twelve-Wheeler! Posed or not, it's a wonderful shot. Kudos to the photographer! Who's the engineer by the way?
