I have been getting my constant force springs for my kinetic art from SDP in the past. I went to buy some and found they are out of stock. They always seem to be out of stock. I see that the springs are manufactured by Ametek Hunter Springs but they will only sell in quantities of 50 pieces. So is there another source?

Dan:

Ive only bought them once from vulcan.. min order was 100.00 , turned out they werent constant force..but they worked anyway. Vulcan still doesnt have any I dont think.. Let me know if you find a source.. I may want a couple myself.. Close to time to do a bat as a posted project I think...
