Re: Sil-Phos Identification

I performed a little electro plating experiment overnight using copper sheet with silver solder and Phoson-0 samples applied. This wasn't the most rigorous application of the scientific method, but it appears that the silver solder sample didn't plate, the Phoson-0 may have, but it's difficult to te...

Re: Sil-Phos Identification

That is a very interesting idea, and it has the makings of a great experiment to see if the plating will cover the solder.

Re: Sil-Phos Identification

In the November 1977 issue of Live Steam Magazine there was an article ' Boilermakers consider the case for Phos-copper', by Tom Rankin. It's interesting how recommendations for a product change based on service experience, sometimes you just don't know until you try. Jimmy, do you want me to cook y...

Re: Dome Patterns

Paul, a few years ago I made aluminum dome castings for my 1" scale Atlantic, they're very different in configuration from those on a challenger, but I think you could use the same technique to cast what you want. I made solid wood patterns for the sand and steam domes and sand cores to hollow them ...

Re: Cute Mystery Indexer

I have seven indexing plates that may fit that head. The plates are 4-7/8" diameter, the center hole is 1-23/64" diameter, there are no holes for the counter sunk flathead screws.

Re: 1" Inch Scale Riding Car/Tender Trucks

Jim, look up the properties of ZA-27, if the trucks are made from from it you may feel more comfortable using them.

Re: Gorton pantograph help

This thing has potential Harold! That's the beginning of a pattern for a fixed coupling, a total of 1-1/2 hours work. It took me longer to make the template than to trace out the pattern.

Re: Suspension problems

Further update, today was the first time I ran my Atlantic since last fall. Over the winter I continued to play around with the suspension by removing everyother leaf from the leading truck springs and compensating for the changed dimension with a taller block under the springs. The softer springs u...

Re: Gorton pantograph help

Harold, I anticipate a lot of trial and error before producing anything of value. I down loaded an instruction book and have been trying to make sense of it. As long as I have the book in front of me I can setup the reduction ratios on the pantograph arms, but the stylus cutter relationship is a lit...

Gorton pantograph help

I just acquired a nice (and heavy) Gorton P2-2 pantograph. I planned to use it more like a router/milling machine than an engraver to make casting patterns and small parts. That being said, it has the potential, if I can master it, to do a lot of neat things. From reading, watching you tube and play...

Re: Help identifying photos

Got it Keith, check your PM. Thanks

Steve, in 2017 I was contacted by a gentleman (CWBuck) who may have Bill's Pacific. The paint scheme was exactly the same.
