Re: Copper Tender

0.050" is much thicker than the material that I have. I've been kicking around the idea of making a replacement tender for my 1" scale 0-4-0 but I think the 0.020 copper flashing that I have will be too thin even if I add stiffeners. Thanks for the quick reply. John

Re: Copper Tender

Just curious, do you have a thickness on the copper sheet that was used?

Re: Phosphor copper welding rods

BDD,I'm making the frame for Kozo's Hiesler in 1" scale. Rather than use brass bars for the frame, as he did, I used cold rolled steel but still intended to silver solder the joints, however, the fit was not tight enough so I MIG welded them and ground the welds flat before applying the gusset ...

Phosphor copper welding rods

Can phosphor copper stick welding rods be used to join mild steel, in other words, can it be a substitute for torch brazing?

Re: Casting sand

Lazz, I've been complaining about the very poor finish on my castings for years, due to the worn out casting sand that I kept using. From over 20 years of use and mulling the sand grains were rounded and full of clay and dust balls that wouldn't compact. The finish on my last two pours were so bad t...

Re: How would you core this?

Ronald, this incredibly horrible casting was actually a success! I'm going to try to develop the lost foam technique that you've obviously mastered. I spent all of 5 minutes hand carving a piece of white styrofoam packing with a Dremel and burr ball, then dipped it in paraffin wax to smooth the surf...

Dan I didn't see your post, you answered my question regarding inside and outside valves being 90 degrees out. Thank you.

Re: walschaerts valve gear issues

Thanks Russ, my project is inside admission. Why would the crank need to be positioned 90 degrees from an outside admission valve as Bill posted. It was that way to start, I repositioned the crank as per the outside timing instructions I posted previously and it wouldn't make a complete turn of the ...

Re: walschaerts valve gear issues

This was the criterion that I re-set the valve gear to, and it didn't work at all on my Pacific project. Oddly, this is the same method I used on my two LE Atlantics and they run beautifully, nice and square. So what's the answer? I had to turn the crank about 90 degrees on the Pacific to get it to ...

Re: walschaerts valve gear issues

Check out the locomotive animation at trumpetb.net, it helped me with a 1" pacific project that I am rebuilding. I had it running on air but started to adjust things and got it got it so screwed up that it wouldn't run at all. What I think I learned (please correct me if I'm wrong) is there is ...
