I needed a new 14 1/2 PA spur gear in a face width that I could not find. I've read from various sources that a 20 degree PA is compatible with 14 1/2 PA but vendors say otherwise. So I decided to match the original gear to avoid headaches.
When I searched, I discovered that Grob Inc. sells 14 1/2 PA gear rod stock. They have an online tool to reverse engineer the diametral pitch. Dakota Koffarnus checked stock and found the correct rod stock. He cheerfully filled the smallest order they could do without a bunch of guff over a small order. The packing job was excellent. A heavy cardboard tube had wood ends inserted to protect the rod ends and the tube had a cut line line indicating where to saw it open. So I'll cut it to length, bore it, and wind up with a nice gear. At the same price as purchasing a single gear, I'll have enough left over to cut 20 or so more. I might even break even by selling them online. So if you're looking for 14 1/2 PA gear rod stock (some call it pinion wire), you might want to check out Grob.
