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!

Re: How do you guys feel about the "Just get it done" attitude?

Remember that there are times to build a watch and times to build a locomotive and get it out on the track. My similar approach was, "I'm not sending this to the international space station" when it came to precision on some parts. Yes, there are certain very critical dimensions and tolerances on s...

Re: Piston mounting

On my mogul, the SS rod is threaded into the bronze piston and then silver soldered. You should never have to disassemble the rod from the piston after assembly.

Re: Restoring a modified Allen 2-4-0 barn find

Pieces of .010 stainless shim did the trick. Then it was on to the valve gear. I had a massive amount of valve rod slop when running the locomotive last year, so I knew I'd need to replace a lot of stuff. I started by ordering the Allen EDM cut expansion links and die blocks. New link pins for the ...

Re: RANT THREAD?

cbrew, I built the rack for the exact same reason: So I can pull the camper and have the loco, tender, and boxcar. My boxcar houses the air compressor and resevoire for my train brakes as well as the 12v battery for lights, plus tools and parts that I may need if things go Tango Uniform out on the t...

Re: RANT THREAD?

6) figure out a way to quickly load or unload your equipment when visiting other tracks. This is a sure way to kill an experience when you're stuck behind someone taking his time to get on/off a railroad. If nothing else, load the equipment, secure it so you can move out of the way to finish tying ...

Re: Stainless steel boiler/exchanger?

My two cents: Save your money, build your boiler from a good piece of pipe and 516-70 carbon. It will outlast any savings you'd gain by spending 5x as much on stainless.

Re: Mid-South LS Spring Meet

So glad to see the roof over the steaming bays! Wish I could have made it up there for the meet; perhaps in the fall this go-round.

Re: RANT THREAD?

On snagging hoses: If you are working with any kind of hose, line, or rope, it will snag when you pull it such that you'll have to climb down off the roof to unsnag it. But if you want to loop it around something, you won't be able to do it, and you'll have to climb down off the roof to loop it. Di...

Re: Steel Prices

Aluminum has had the most significant increase in cost over the last two months. Carbon bar products (HR bar, 1018, 1045, etc.) have been minimal but rising. Carbon sheet and plate is up over 10cent/lb since February and supply is becoming limited. If you're looking for 516-70 for boilers, you'd bet...

Re: Allen Mogul Timing

Are your outside rocker arms silver soldered onto the shaft, or still only held in by the roll pins (as called for on the drawings)? This was a design flaw that is known and almost everyone goes back and silver solders the arms to the shaft. The pins would wear the bronze arm casting and introduce a...
