DIY Solder Pot Answered

Just today, my brother offered to give me his old coffee maker that he had replaced with a newer one. He is well aware of my electronics hobby, which is why he offered to give it to me in the first place. Nothing is wrong with the coffee maker electronically - he just didn't use it for a long time in which it became moldy on the inside. He cleaned the inside properly, and as a precaution I did it a second time.

Now that it is cleaned, I'm curious as to if I could turn it into a solder pot. Seeing plenty of DIY solder pots, I'm thinking I could use an empty soup can, cut to a reasonable size, and have it rest on the heating element of which the coffee pot would normally rest on. Would I be able to do just that or no? Any suggestions as to what to use for the "bath" or "pot" of which will hold the molten solder?

Thanks in advance!

P.S. This is a basic electric drip coffeemaker I'm wanting to salvage - just to clarify.

I've been interested im doing this as well for a while now.

But since I want to use it for bulk harvesting, I want to use the warming plate itself as the pot. It's wide and shallow, but just deep enough to hold enough solder for what I want to do.

I tried converting one a while back, but if course ran into the built in temp limit. Opening it up, it has a thermostat that automatically shuts it off once it gets to the max temperature.

I tried putting some space between the thermostat and the plate to see if I could get it to allow the plate to get hotter but had no luck.

I want to keep the auto-shutoff working, just want it to shut off once it's reached the melting point for solder instead. Maybe sone insulation?

Any ideas out there? I can't think of a better way to recycle an old coffee maker :)

377F. Melt temp solder. 212F boiling temp water.

Although I prefer Celsius :)
The heating element itself might be capable of getting to the temps you require but:
1. There is a temperature switch that cuts out at around 98°C.
2. There should be another temp switch in the form of a temperature fuse - they usually fail around 125°C.
3. The entire design is based on the max temp of boiling water, unless you mount the heating element onto something heat proof anf preferable with insulation for your pot it will all melt.

A solder pot for normal tinning of wires and such is better done small and as a replacement tip of a big soldering iron.
I have even seen clip on ones for wood burning tools...
And although we all like to think poisons are a thing of the past, using normal lead based solder for prolonged time in such a solder pot would be thing for outside use (or with an exhaust system).

However, with some little modifications the hotplate for the pot would make a good warming plate for the big family dinners or bbq's ;)
