This is my first instructable, and I've decided to document me building a Mandrel.  This project took me roughly an hour to build while taking pictures. It's a little different than other Mandrels I've seen on this site, so I figured it would give people more options.

Step 1: Materials and Tools

First you'll need your Materials and Tools.

- 32 inch 5/8" Metal Dowel
- 32 inch 3/8" Metal Dowel - This determines the inner diameter of your rings
- (6) 2 1/2" Screws
- 4ft piece of 1x5

- Power Drill
- 5/64" Drill Bit
- 3/8" Drill Bit
- 5/8" Drill Bit
- Screwdriver Bit
- Saw
- Measuring Device
be careful with galvanized wire. prolonged contact with your skin can cause some serious problems. I use aluminium fence wire for jump rings.
Interesting and very reliable design. Have you thought of putting a guide onto this rather then use your hand?
I did consider placing a second bar very close to the first, but it would have messed with the vice grip. If I did that I would have needed to drill a hole into the first metal dowel to hold the wire. Since I don't have a reliable way to do that, and this was a lot easier, I just went with this.
