Re: Silver Soldering Leaf Springs

Given the content of this thread, I just reflected upon my memory of the construction method for the LE springs (at least, in 1" Scale for the pacific/0-6-0 variants)... There is a single leaf spring that gets this sort of block/pivot point silver soldered to it. But when assembled in the stack, the...

Last step will be to install in the fire box, hook up the new throttle intake plumbing and run tests to confirm optimum oriface diameter.
You're putting this in the firebox? Odd.... :shock: :D

Re: Laying out rectangular cores on foundry pattern

Gating and Risering should be left to the foundry's discretion. I have experienced core prints with a more severe draft angle. Say 10 degrees. This allows for more play when setting cores. The tighter the draft angle, the more accurate you must be in setting the cores. But if you go with a more gene...

Re: Laying out rectangular cores on foundry pattern

Hi Mike, I should be in good shape on the core prints. They are 2" in height with a 1.5 deg taper down to the valve face and ample on the cylinder bore side Sure, but your cores will expand and contract. So if you are targeting a dimension with your 2" height, I would expect that dimension to be of...

Re: Laying out rectangular cores on foundry pattern

Also something to take into consideration - the cores will expand and contract when they come in contact by the molten metal. You will need a core print, and that is another factor to take into consideration. You will experience the expansion/contraction and need some "give" for the core so it can m...

Re: Never seize in lieu of pipe dope

I did a very unscientific test with Teflon tape when I first started to tear down my front end. As a test, waved a lighted cutting torch across a strip of Teflon, I had placed on my welding table - it flashed off and disappeared in an instant. Zap and it was gone. So decided, oops, better not use t...

Re: Worthington Duplex pump & Brass Hex head screws

Unfortunately, I think you are in way over your head. Don't take the above too closely to heart. While you are new to this, this is nothing you can't learn. The first step is to ASK for help, which you have done. Hopefully you can find a mentor. I do agree that you should try and find your local li...

Re: Compressors on Ebay

No, just remember there was a very large auction a few months ago. There were probably a total of five or so of these compressors being auctioned off. Went rather cheap, too... $300 a pop, I think? I was advised that they might be non-functioning salesperson's samples, so... Hopefully the buyer appr...

Re: Compressors on Ebay

These were at auction a few months ago. I was shocked at how low some of these pieces were going for. This seller is flipping the compressor(s).

Re: Front End Rebuild

Can’t imagine why the boiler maker welded the throttle pipe to the front sheet of the boiler. Cause folks don't think about the next person owning/working on the engine. "Well, I can weld a nipple in place, just gotta drill it and lay a bead..." vs "I could weld in a female pipe coupling so i don't...
