Re: Which pressure gauge to use?

Actually, I very much enjoyed your post -particularity opening the post and seeing the bellows - perfect humor, considering I was just reading about using one. On to the serious stuff... front end researchers in the 20’s and 30’s were able to improve boiler performance routinely up to 42% by replaci...

Re: Which pressure gauge to use?

Ryan, I am rarely at a loss for words, but here, I think I am definitely on pause! :shock: :shock: :shock: Plus, After getting NO vacuum reading out of my smokebox today with my home made manometer I may just go right out and buy one of these! BTW, just reading Koopmans’s great historical accounting...

Re: Which pressure gauge to use?

Thanks all. I made up a plastic U tube such as you all have recommended, to check my smoke box vacuum. Hope to see what it shows tomorrow. This will be the ”before” measurement. Carl, main reason to do this, is I need to replace my existing blast pipes with a Lempor ejector system and want to find o...

Which pressure gauge to use?

Hello All,

Looking to buy a pressure gauge to monitor vacuum in my smoke box (12” coal fired boiler).

I see two types of gauges on Amazon: 0-10 and -10 to +10, with zero inbetween the high and low numbers.

I assume 0-10 would be fine??

Thanks
Glenn

Very sad to hear. We’ve lost a true, old world craftsman.

Re: Fire in the smokebox?

Greg, My guess is they were cleaning up some carbon build up in the front end. And he sprayed a flammable solvent of some kind on the screening surrounding the evacuator (blast nozzle and stack extension inside the smoke box) to flush the fines off the screen, then burn them out through the stack. T...

Re: Verifying Blast nozzle height

Pontiac guy, yes, our house water temps are also colder in winter, although around Seattle it’s more temperate than the real winter states east of the Coastal range... I’ve found sewn mica fiber thermal blanket on line that looks reasonable. Need to go measure max size I can fit under the lagging. E...

Re: Verifying Blast nozzle height

Thanks, I think that’s direction Iam heading. One of our local master machinists makes a petticoat taper on the bottom of each of his nozzle orifaces. - also drills the holes with tapered bits! Says it improves flow in the orriface by 20% or more. Pretty amazing.

Re: Verifying Blast nozzle height

Ryan, yes, agreed. I’ve decided to move the blast nozzle down to calculated height above the extension, when I rebuild the front end. Oriface diameter is critical, as many have said. Iam still learning about multiple oriface nozzles. Several people have mentioned they tried multiple ports with no ga...

Re: Des Peres Valley #4 - Baldwin 0-6-0 using Allen Models parts.

Great choice. I love your family connection to the particular loco. It’ll have great historical connection when your done and operating it! I wonder if Kozo’s book might be of some help? Maybe you’ve already seen it. I’ve read it several times and use it as a procedural guide for fabricating various...
