Looking for 1/4 inch mandrels?
 

I can't remember who or where I read that someone was looking for 1/4 inch mandrels. Devardi carries them. They come in a package of two rods for $3.99

you can purchase a pound of 1/4 inch stainless steel welding rod for about $13 and make your own. I either use bolt cutters or the chop saw and then grind the ends smooth.

I bought mine from a hydraulic place years ago, it was so cheap! I used a pipe cutter to cut mine. I hear of others buying brake line for cars, hobby places...

omg sorry I thought you were asking where to get some from, my bad!

I bought mine at ACE hardware. They have 1/8, 1/4 and 1/2 inch stainless tubing.

Maybe not all of them, though. I've been to some that didn't.
