ISO an old fuel sender

[adam metzger]

Hey all-

I'm in search of an old used fuel sender from this group. I'm going to try my hand at rebuilding/refurbing them. If it goes well, I may offer my
services to the GMC community. I already owe this group more than I can repay, and I thought it would be nice to possibly keep this in the community.

thank you Dolph! PM sent. If anyone else has a sender they'd be willing to part with, I'd love to have it. I have a lot of experience using very
small materials successfully, as I have a side gig tying flies for fly fishing. I think wrapping 40 gauge wire might be right up my alley.

A question for the brain trust.

I know that nichrome wire heats up when voltage is added. It's commonly used in hot knives to cut foam. my question is, would heat affect it?

The reason I'm asking is this-

I soldered the tab that I broke on the potentiometer case. now the sender wont show a reading.

I can't imagine that wire that could withstand hundreds of degrees through voltage could be affected by indirect heating of the case surrounding it,
but I'm not real smart.

thoughts?

Adam,

Nichrome is very much like a stainless in that it protects itself by forming a hard oxide surface. I do not believe it can be soft soldered. I have
managed to both cold crimp it with lots of cleaning and a really hard crimp. I have also successfully connected it again with a lot of cleaning and a
silver brazing alloy. It is just terrible stuff to work with. You have to clean it with silicon carbide paper or a file.

Good Luck

Matt

II used to work at a company that made heaters. Everything from waffle makers to laser ring gyro temperature control.

Nichrome is a very good material for a heater, it has a decent resistance to oxidation good resistance vs temperature ( not too high ) and workabilty.

We used it in ovens that regularly ran red, or even white hot for hours and hours.

Not very solderable, but it can be done with a good acid flux IIRC. We used to parallel gap weld it, like a spot welder but both electrodes on the same side.

I'd look into crimping like Matt said

To answer your question, it definitely can handle soldering temperatures. You problem is probably elsewhere.
