Re: Two Silver Soldering Questions

Matt,

Silver brazing/soldering small parts can be done quite easily with mapp gas and it's a good way to gain experience. My boiler is for a 1" scale loco. The copper boiler is 5" in diameter and 19" in length. Fire insulating bricks are a must, not stove bricks for the large heat ups.

Re: Two Silver Soldering Questions

Matt, Since you are building Kozo's A3, stick to his methods described in his book. The process is simple, the equipment is simple and it works well. I built a slightly larger boiler, 1st time build, using his techniques, because it works! Here's a link to my copper boiler build using Kozo's methods...

Re: Two Silver Soldering Questions

Kozo is quite explicit about not using oxy-acetylene or oxy-propane. Check out page 238 of his book and Kozo explains why this is not recommended for a beginner. Propane, with the proper burner, will work just fine. Smaller, cartridge type torches work well for the smaller parts and for the boiler, ...

Re: Two Silver Soldering Questions

Fire bricks will work okay, but, "insulating" fire bricks will reflect the heat back into the work, like these on Ebay: https://www.ebay.com/itm/K-20-Insulating-Firebrick-9x-4-5x-2-5-IFB-Straight-Fire-Brick-INDIVIDUAL-BRICKS/200894655270?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649 I t...

Re: Two Silver Soldering Questions

Hi Matt, Black flux works fine, even for very small parts. Since I have discovered it, I use nothing else. As for building up your milling error, it might be difficult to build it up with silver solder. Silver solder flows are pretty flat, but, you could silver a small piece of brass to the spot in ...

Re: RANT THREAD?

Reminds me of another one! Tiny hex-head nuts/bolts on models with no known wrench size! Not Imperial, not Metric ... British, maybe, they have some WEIRD sizes! B.A. (British Association) threads have their own special hex sizes, not to mention the bolt diameters and special pitches. To use them, ...

Re: Super Simplex 0-6-0

Hi Benjamin,
You caught me again! I hope you found my website useful. There is lots of information for first time builders. I just recently added a page for making cone unions.

Enjoy!

Re: Union copper tube to 1/4-40 MTP ?

Hi Dianne, I'm glad you found the information useful. To be sure, what I have shown is not precision machine work. It's pretty quick and dirty, but, it works well. There are only two dimensions that require a micrometer or caliper, those are the two diameters of the cone. Even those diameters will w...

Re: Union copper tube to 1/4-40 MTP ?

Hi Dianne, I pretty much do as Richard has described including the Cerrobend method for tight bends. Also, I have just finished a page on my web site that shows pictorially what is involved in making cone unions. The parts you see in the photos I just made tonight for the new page. it took much long...

Re: Union copper tube to 1/4-40 MTP ?

It's actually not too hard to make cone unions. I made all of the fittings for my loco. There are only a few diameters that need to be turned, and they are not very critical. A "how to" for this sounds like something I should add to my website. Off to the shop with my camera!
