Re: Mystery bronze

Based on the color I was a lot hotter. I wonder why it burned to all dross and not just concentrated copper?
Thanks. John

Re: Mystery bronze

I think we know...it turns to dry ashy dross. Crap, I may be remaking a bunch of bushings! Explains why it machined so well. Thanks David, it's not the answer I wanted but at least I know what it is now.

Re: Mystery bronze

David, why do you think it's red brass, in the first response to my question Frank also thought it may be brass? I'm curious, I've been using the items that I cast on an engine project where bronze, not brass, is the appropriate material,I always thought all water meter bodies were bronze. Also, wha...

Re: Cylinder honing

Thank you all! Hones are out...Cycle Pro here I come. Thanks for enlightening me, when I started this restoration I found the the distances from the center of axle to center of crank pin to be different on each wheel, and significantly different from side to side (it would only turn with a few bushi...

Re: Cylinder honing

I believe it, the cylinder with the packing yarn had better compression than the one with rings! And that's with a cylinder that looked like it had a screw thread in it! Hi Marty, good to hear from you, I'll call around, but I don't think any engine shop is going to want to fool around with anything...

Cylinder honing

I'm rebuilding an old 1" scale locomotive, I noticed that the maximum stroke was different in the right and left cylinders. When I got into the cylinders I found two different length pistons, hence the different strokes. But what was really interesting was someone had used packing yarn instead of ri...

Re: Class Lamps and Smokebox Heat

Attached is a photo of my 1" Atlantic's working classification lights and headlight. I made 20 ga. steel mounting brackets to stand the lights off from the smoke box and used 18 ga. high temp (insulation) wire with shrink wrap for the conductors. I packed the resistors for the classification light's...

Re: Mystery bronze

H. You hit the nail on the head with your edit, last week I was cutting angle iron on the saw and was zipping right through it, that's why I didn't think it was dull. I did a small experiment today melting about 1lb of bronze under a borax cover. It melted with no dross formation. I poured it into a...

Re: Mystery bronze

Harold, I've never been told that I have a dull saw in a nicer way:)
So far I'm not having much luck finding out what this is.

Re: Mystery bronze

Once I got through the outer scale the material machined very nicely. It's very difficult to saw, but machines like butter...I wouldn't have thought that. I'm going to call one of the larger scrap yards and ask, they will probably know.

Re: Mystery bronze

Frank, I believe this is bronze, but what type of bronze? Silicon bronze, aluminum bronze or something else; not too long ago the EPA mandated unleaded bronze for the water industry, this meter body predates that. I have been trying to research what it could be, but there was no name on the piece I ...

Mystery bronze

I wanted to make some bronze bushings but was out of suitable sized rods, so I figured I would cast a few cylinders in the diameter that I needed. I had part of an old water meter casting laying out in the back yard for about 20 years. It was there because it was next to impossible to break up with ...
