Building a Mandrel for coiling wire. (Chainmail)

Picture of Building a Mandrel for coiling wire.  (Chainmail)

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.

Materials
- 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

Tools
- Power Drill
- 5/64" Drill Bit
- 3/8" Drill Bit
- 5/8" Drill Bit
- Screwdriver Bit
- Saw
- Measuring Device

Step 2: Finding the right Holes.

Start by cutting your 4 ft piece of wood into  two 1 foot sections and one 2ft section.  This step I had done when I bought the wood at Home Depot.

Next, mark the locations of your holes on the 1ft sections.  My first hole I marked was for the larger 5/8" dowel.  I marked that in the center of the wood and roughly 6 inches from the bottm.  I say roughly because my tape measure is missing and I really just eyeballed the hole.   This hole is placed high enough that when the spool of wire is on the dowel, the spool will be clear of the bottom of the Mandrel.

The next hole to mark is the hole for the 3/8" dowel.  I marked that about an inch diagonally from one of the top corners.

Next, mark the pilot holes on the bottom of the 2ft section of wood to attach the other two pieces.  I did this by placing the pieces about 1 inch in from the edge and marking 3 holes in a strait line.  The reason I placed them in from the edge was so I did not risk spliting the edge of the wood with use.

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.
