Re: Boiler Water Gauge Replumbing

...or any time one is suspicious of a plugged water gauge! Have at it. RussN That's a nice clean looking cap. I blow the glass down every time I steam up. Rolling along one day I had a sense where the water should be but it wasn't. Watching the glass for a moment the level was rock steady and it sh...

Re: Tubes...leaking

A leak at the tube sheet in itself isn't a disaster. When I did club boiler inspections it wasn't uncommon with rolled tubes. It might be as easy as touching it with a roller again. It doesn't take much. If corrosion has taken hold that's another situation.

Re: Tubes...leaking

It is unfortunate but quit the live steam hobby...certainly not. We brushed 3/4" K type copper flues with a stainless shotgun brush at the end of each day. One pass down and back by hand. After 12 years corrosion lead to a crack in one of the firebox side sheets but the tubes were fine. The second b...

Re: Piston Ring Question

In the Manual of Model Steam Locomotive Construction, Martin Evans briefly discussed the fit for iron piston rings and mentions using "one or more grooves" packed with graphite yarn. There are enough references to graphited yarns for it to be viable but I would say iron piston rings and polymer seal...

Re: USPS is a mess...

While politicians clamor for the postal service to cut losses and be more efficient, the postal service provides locations and services its competitors do not. UPS and FedEx cover my area from service centers 40+ miles away that cover at least two counties. You ship by printing your own forms and dr...

Re: Show us your milling machine!

This was my dad's machine. I did a little work with it this week and thought I'd share it. It's a Browne & Sharpe No.1 Universal Milling Machine. I'm told the Yerkes Observatory was the original owner. It's a line shaft machine fitted with an electric drive. Along the way it picked up a Bridgeport h...

Re: This is my workbench now, what can I do to improve it?

My dad started his first locomotive when I was in my teens. With children still at home his budget for locomotive building was limited. He did everything in a four jaw chuck. It was slower than a three jaw at times but this was a hobby not his profession. His wheels were turned on mandrels. His axle...

Re: This is my workbench now, what can I do to improve it?

Can you tell me more about this? I probably want to finish all the wheels before I make any axles incase I accidentally bore the axle hole a little too big on some, I can compensate leaving more meat on an axle? Which side of the wheels do you think should be machined first? When I turned my driver...

Re: This is my workbench now, what can I do to improve it?

I agree. Before I begin a locomotive I should probably look at every part and plan out how I'm going to do every piece first? To a degree. Assuming you build a successful design with the capability of your equipment, it would be a good idea to give some thought to the overall sequence. But I would ...

Re: This is my workbench now, what can I do to improve it?

What else can I do to be a faster machinist? Make something. Text books and Youtube will get you the basics of machining. With experience you will begin to visualize the most efficient/accurate way to handle the part through the machine. How to hold it. How to measure it accurately. How to locate h...
