Re: silver soldering steel to steel

The obvious question is; why not take a couple of pieces of the steel you are going to use and try to silver solder them together? This should give you all the answers you need before you put any significant work in what you want to make. Good advice! I have just done this with the N&W tender bogie...

Re: N&W S1a Project - Tender Build

Dan and Harold Thanks once again for sharing your experience. It looks like I am now back on track (pun fully intended) to machining these wheels up in a reasonable amount of time. I dropped the spindle speed just one more pulley and things improved significantly. Cutting through the scale was done ...

Re: N&W S1a Project - Tender Build

Harold and Dan Thanks so much for your detailed replies. Here are some factors that I see contributing to the problem. A. machining experience B. tool grinding capabilities C. lathe size - power and rigidity (it is a relatively small lathe) D. material selection. Before I started on the real wheel, ...

Re: N&W S1a Project - Tender Build

As above, I need to make a small adjustment to the bending jig to finish it all off, then onto mass production. So that has been set aside for a bit while the wheels are attacked. I picked up some discs from a (not so) local supplier and have managed to finish off one wheel - see photos below. Turns...

Re: N&W S1a Project - Tender Build

Thanks, Bob. Very kind of you to say. Almost done with the jig. The very last bend ended up being a little short so will need to rectify that before getting into mass (4) production. Frames will be brazed together - not sure if I will go silver or bronze at this stage. I am thinking silver as it sho...

Re: N&W S1a Project - Tender Build

Not too bad - just a little slow. I did have a false start as I did not account for the 0.4mm channel in the second bend, which added a few unnecessary holes.

Re: N&W S1a Project - Tender Build

All After bending one of the upper parts of the bogie frame by hand, I thought it might be better to make up a jig to get them all to end up the same size. Here is the first bend 40. BendingJig1.JPG The bottom bend 41. BendingJig2.jpg The last bend 42. BendingJig3.JPG Here is the end result matched ...

Re: N&W S1a Project - Tender Build

I'm nothing if not old fashioned!

I guess the originals would have been cast which makes me feel better about small imperfections. Well beyond me to even think about making patterns for these!

Re: N&W S1a Project - Tender Build

All The bulk operations for the bogie frames are all done now. Here they are set up, bolted together with two 3/8" dowells to keep them all in line. 28. Bogie Frame Bulk C.JPG After fly cutting both sides of the block, the middle section was removed by drilling and milling to finish. 30. Bogies 1st ...

Re: N&W S1a Project - Tender Build

All So the first of the eight frames required for the bogies has been finished off. The top and bottom of the bogie frame had been slightly channelled to accept the frame to make the set up a little easier. 17. Bogie Parts.jpg Top and bottom (mostly) bent to shape here and mocked up with a prototype...

Re: N&W S1a Project - Tender Build

All Thanks for the replies. Asteamhead, those nippers are not used often but are certainly very handy when needed. Nothing too exciting at this stage, but some progress nonetheless. I expect that this loco will be capable of hauling a significant train so I was a little concerned about transferring ...

N&W S1a Project - Tender Build

All It has taken some significant time for me to get started on this so I thought it might be good motivation to record the progress of this build here to help me moving in the right direction. This is a first time build so please feel free to offer any suggestions you feel might be helpful. The (qu...
