Stickers and Thanks!
Added 2021-08-03 00:07:49 +0000 UTCHey Patrons! It's that time again. Stickers are in the mail for all new Rockstar Patrons who joined in July and credits have been updated on the videos and blog. I'm so grateful for all of you who stick with me month after month and make it possible to produce this content. As always, never hesitate to reach out with questions or comments!
This month's book feature is Kozo Hiraoka's The New Shay. If his Pennsylvania A3 Switcher project was too easy for you, then step up to The New Shay. It's a revised version of his earlier Shay model and continues his tradition of amazing drawings and build instructions. What's great about the Shay is that zero castings are required. The Pennsy does use castings for the drivers (which can be bought from some foundries online) but the Shay is entirely fabricated from bar stock. Quite a remarkable achievement. Personally I love geared logging locomotives. They are the off-roaders of the railroad, handling steep grades, tight corners, uneven roadbeds, and unforgiving conditions. The Shay is the king of logging locomotives in my opinion, so I do hope to build this some day. The side-mounted pistons drive a complex crankshaft which powers the wheels through articulated drive shafts and the iconic bevel gears. This layout means the turning radius and suspension travel are not limited by the slop in the piston rods and flange tolerance on drivers, as is the case on traditional locomotive geometries. Furthermore, side-mounting the cylinders makes room for a third, and the cylinders are in contact with the boiler (which keeps them hot). A brilliant and hardworking design that pulled logs out of the woods for 100 years!

Hi Quinn I used to run boilers of different sizes and makes so what you are doing in your build interests me very much

2021-08-15 19:42:22 +0000 UTCTinning is not something you can do with silver solder. It's different than soft solder in that it doesn't really stick to itself. You only get one shot to make the joint, and it doesn't re-melt well after the first time the way plumbing and electrical solder do. It's more analogous to brazing cast iron than electrical soldering.

2021-08-10 17:20:38 +0000 UTCThat's pretty much what I did by accident on my latter attempts to repair. You'll see in the video, but the whole top plate ends up covered in solder. All that solder is doing nothing if it's not down in the joint, though. Drowning the area doesn't get the solder to flow down into the joints. You have to pull it down from below with heat, which is nearly impossible to do from above.

2021-08-10 17:14:23 +0000 UTCThis is actually what I attempted on initial assembly. This is the method recommended by Alex Weiss' book. However I think I will try a different approach next time because that method is difficult to execute.

2021-08-10 17:13:10 +0000 UTCHi Quinn, just a thought when you start again. Maybe use a beading tool on each end of the pipes then tin the bead(olive) and then put the tube holders on after tinning their holes beading tool demonstrated at 25 minuets into edd china’s video https://youtu.be/XHi9iQNNII0 Am sure you could figure a way to clamp the tube holders together holding the holders tight to the olives. So the olives would be on the inside of the boiler. Hope I have explained that clearly enough. Uf not pm me. And good luck

2021-08-10 14:17:54 +0000 UTCI know nothing about boilermaking but was wondering similar things to James Strickland. Could you win by sheer volume? eg just drown the area in solder.

2021-08-10 02:23:43 +0000 UTCIs it possible to heat the whole boiler hot enough to melt all the silver solder at once? Would that help, or make things worse? Seems like it would, at least, make disassembly easier.

2021-08-06 00:52:07 +0000 UTCHi Paul! There are no plans for that project, because the only part I made was the draw bar, which was specific to the collet holder I happened to have, and the exact dimensions of my lathe. It's just a bar with threads on both ends, in any case.
