Mr. Prongy in that picture over there over there is what one does when one needs to solder four brass bearing surfaces to the inside of a square tube.
(As soon as you heat the tube to install the next one, one or more of the others melt and fall off or move.)
Using a shop-made tool†, the procedure is merely slightly fiddly:
- generously tin 4 inside surfaces
- generously tin the bottoms of 4 brass bearings
- using your preternatural manual dexterity, place all four bearings in place, using the tool to hold them.
(note: the author lies, he soldered two of them in place first before he realized he was stuck and would need a tool, so now it will be much easier than the above. -- sincerely, the author's other hemisphere) - apply heat until everything settles into place under spring* pressure
* "springy", LOL, yeah right! This is A36 structural steel, it has forgotten what carbon ever felt like, so good luck actually making it springy, temper-oid, hard-ish, etc. The fingers were springy enough to do the job once I cut them 2X as long as I thought they needed to be...
† making the tool took me, oh, 30min of actual labor I suppose - not including a break or three. Not a lot of time for a project which overall was taking many man-days of labor
When it was all said and done, this is what it was for:
It still hasn't been painted yet...
