Re: Using a steam indicator

Tubing that completely full of liquid right up into the transducer will transmit pressure changes very accurately and quickly. Trouble comes when there are bubbles in the tubing. Then all the fluid up to the location of the bubble has to move as the bubble expands and compresses with pressure chang...

Re: Final Bore is under spec

...One hits size by chance if the exact measurement isn't known. That's why I asked how the dial bore was set. It may provide repeatable readings, but they may or may not be the actual size if not set by a ring. I've been embarrassed by that issue more than once in my life. H Harold, What about set...

Re: Using a steam indicator

FWIW Aside from the hardware aspects to the digital steam indicator (pressure transducer, crank position encoder, Digital Analog Converter, assorted data acquisition & signal processing gear) -- I forget now some of the hardware stuff I had worked out -- I would think that you can solve for the area...

Re: Precision machinist

I'm not as old as some of you guys, but in the late 60's we had classes available like welding and small engine repair beginning in the 7th & 8th grade . I know, because I took them starting in the eighth grade. Admittedly it was a rural Middle school where such things were deemed necessary by the f...

Re: Enco/Gamet Boring Head

I just bought one of these Enco Made in France automatic boring & facing heads on ebay for about $125. Looks like it hasn't suffered any damage just has little bits of surface rust. I have downloaded the manual but it is rather sparse in it's attempt to explain how it is used, and the pictures look ...

Re: ALCO Type E Power Reverse

here's a picture of the power reverse on my prototype, an ALCO 2-8-2 Mikado. I'm guessing it is an ALCO power reverse but it may not be. My guess it was added some time after the loco was built and initially sold. From what I've been able to determine, appears they moved the air tank to make room fo...

Re: ALCO Type E Power Reverse

I forgot to ask:
Tim, you say you are printing wax. Do you use Moldlay or what wax filament do you use, out of curiosity? I don't have a 3D printer yet maybe next year.

Re: ALCO Type E Power Reverse

Tim,
I might be interested in the Power Reverse castings, depending on the cost.
