Re: 12VCompressor for a Brake Car

Our club uses the Tom Bee compressor unit on our club cars with great results. It powers breaks for four cars.

Re: McMaster carr part number

My local Ace Hardware sells the coils of heavy wall tube. A long time ago I bought one coil each of 1/4 and 5/16 and still have a lot remaining after piping two locomotives.

it appears that mating isn't the greatest challenge, It is keeping the things coupled, especially upgrade, on a curve.
That sounds more like a track issue than a coupler issue.

Re: Atta Boy for Eccentric Engineering Injector

Had to come and give a huge thumbs-up to EE's injectors. My wife bought me one as a Christmas present this year (how about that?!). Installed it last week and ran yesterday and it worked the first and every time without any issues at all. So glad we have a source of reliable, well built injectors ag...

Re: Coal dust bricks again

I built my coal hopper car with 1/4" opening wire mesh over the chutes out the bottom to let all fines work their way out as I pull it around. Having a readily available supply of really good blacksmith coal available in the area there's no reason to recover the fines and process them into useful bu...

Re: Steam Dome Throttle

Hmmm, that has possibilities. I'll look into similar ball valve installation into my steam dome. Regarding the ball valve itself: How do you find the operating characteristics? Can you get a smooth launch without a jump forward or instant speed or easy wheel slip? How about low speed regulation? Ca...

Re: Steam Dome Throttle

Check out how I handled the ball valve and linkage here:

I've built two this way and they work great. Used an off the shelf 3/8 ball valve from Ace Hardware and all stainless materials for the rod and lever.

Re: OMG, Kamikaze bugs!

If you use Tom Bee's brakes on your rolling stock, cover the Schrader valve connections when in storage between runs. Prime targets to get filled with mud daubber muck!

Re: Best way to pin Stephenson eccentrics

I learned from Fred_V a long time ago a really, really good way to do it. Once you have them set, use a drill through the eccentric to put a V dimple into the axle and then put a pointed set screw in backed up by a flat set screw. I did this on my Allen mogul and they have not moved whatsoever in 6+...

Re: Candice Bergen remembers Disney's railroad

I was just at Disney World last week and on the way out of the Magic Kingdom I noticed that the lower part of the station at the park entrance is filled with photos of Walt's live steam railroad. This was at the end of a very long 14 hour day at the park and we were on our way out so I didn't get a ...

Re: Broken Drill Removal

I've used alum to dissolve a broken tap in a brass part for a pump I was building. I put the part in a small crock pot with water and alum and left it on low for a couple days. The tap turned to mush and washed right out of the hole.

I found alum at WalMart (but not at Publix or Kroger).

But Im not anticipating a lot of force on the stack itself since it will eventually be a Radley-Hunter.
Just be sure that when someone jumps in to "help" you move your loco to remind them not to use the stack!
