One thing I've learned living on the prairie, what your using as a landmark today may not be there tomorrow.
Often I bring stuff home thinking I'll use parts of it for a project however when i tire of moving stuff around I'll often gift to neighbors and what has no takers I'll take a load of trash to our local landfill.
Canada discontinued the use of the penny several years ago, most banks will not accept them. I did however find one in Brandon that had a coin counting machine.
It was on a trash day, the two pails of penny's were just sitting as shown on an old dishwasher. The shinny copper caught my eye.
When the weather is good often Pat and I will take a lunch and make a day of visiting the various landfill sites, Sandy Lake, Erickson, Onanole, McCreary then Kellwood.
The custodian at the Strathclare has a tricky personality, very difficult to read so I mostly go after hours to avoid confrontation.
When ever I'm in Neepawa I'll stop in at the scrap yard where the owner gives me picking rights. Small bits and pieces like an old magneto or perhaps on old Briggs or Clinton engine.
From my last scrap yard visit there were several large roof top air conditioners. Sawzall cuts the soldered joints off in minutes.
The copper elbows at the end of the condenser and evaporator coils are silver soldered, not pure silver but an alloy - might have something to do with my forum Nic.
The elbows placed into an old flower pot with a positive lead from a DC power supply, negative to the stainless steel cathode sheet , could use a copper sheet.
As the copper is plated onto the cathode a thick layer forms which is easily peeled off as a sheet, if to much power applied makes for a spongy cooper.
The copper plates over leaving the silver behind as cell slime's which will be further refined into pure silver.
