Silver solder suggestions

Correct but I'm currently soldering steel tubing and have silver soldered copper, both very different from conventional copper soldering.
 
I'm soldering steel tubing with 56% silver solder and it must be red hot. Extremely strong joints.

We could pay $50 each and just pass it around to look at it. He might make $1000's that way. I'm interested as well.
 
Looks like you are making landing gear for a large-scale model. Very nice. I fly RC also - mostly 40 and 60 size glow engine stuff.

Yes! 1/3 scale Nelitz Cub build. I decided to eliminate any wooden dowels between the engine/ landing gear and wing area.

I fly 60 size classic pattern planes (wheels up and on the pipe). WFO for non rc'ers. Also 120cc and 170cc planes.

Wow! Very nice work. I have not seen a model fuselage built up from steel tubes like that before. The construction looks like a full-scale Cub.

I toured the Piper museum in Lockhaven PA last year. The factory is closed of course, but the buildings are still there. That is where they built the Cubs - from the J3 to the PA18.
 
The Bob Nelitz 1/3 scale plans are exact scale. His design just used brass tubing in the area of the landing gear connection points and some steel tubing in the wing support area. I just decided to be sure and went nuts on steel tubing in critical areas.
 
WOW.....this discussion took a weird turn,from silver solder to model planes :laughing: .Tipical H-M. I would love to see the finished plane. I want to bond HSS toolbits to metal with a strong bond. Back when I used to work for a boss,we used flux coated silver solder with a acetylene torch set not too high,but that stuff is too exciting for me. I need something cheaper,but with strong bonding capabilities.
