I need a dull, old, used circular saw blade to use as a ground plane for a ham radio installation on a vehicle. If anyone has one they could send me I'd be very grateful. Thanks for reading this...
Used circular saw blade, anyone?

What size? Wouldn't a softer, less "sharp" piece of metal be a better choice?
I am looking for at least 6" diameter. I'd take any scrap of bare, unpainted metal someone could donate to my cause, I can even PayPal a couple dollars for shipping if needed...thanks!
A sharpening shop would probably have plenty of junk ones lying around that they would give you.

Maybe it's supposed to be a multifunctional appliance. I'd be worried had he also asked about an old porcelain bathtub and a giant sack of lye.
That's a joke, kiddos.
How about a paint can lid? Round, about the right size, nice rolled edges give the thin metal some stiffness. I bet you could get a clean one at a paint / home improvement store.
I was just going to say the same thing. you can buy a plain steel 7 1/4" circular saw blade for about 5 bucks. I know absolutely nothing about the radio part of it though.
You aren't going to use that for CW on the 160 meter band, are you ??

I have a circular saw blade I could send you, but it isn't very dull or too terribly old.
If it'll work for you, just send me a PM with your address and I'll send it out to you. Shipping shouldn't cost too much - maybe $5 tops, if that?

Seems like a pretty small ground plane unless you are talking upper UHF. And it also seems like the cost and hassle to get a used blade is higher than to just buy a cheap new one locally.
What Pablo said: Wouldn't you be happier with some softer steel than a sawblade?
Yes this is for a 70cm ground plane, installing underneath a 1/4 wave NMO mount antenna on a fiberglass body.
I have started to work the phones with local metal shops and already have several leads, I am heading out tomorrow to probably pick something up. Thanks for the ideas!
