You will need:
-Lathe with a 7mm mandrel
-7mm drill bit
-Old cloth rag
Making this pen took me about an hour to complete. The longest part is waiting for the super glue to dry.
Next you will need to find the center of the wood block so you can drill a hole.
Draw a line from corner to corner and form an X at the end of the block.
To ensure you get a straight hole in your wood block, use a clamp to hold the wood in place as you drill through the center of the X.
Use a 7mm drill bit and drill all the way through the piece of wood.
Coat the brass casing with a good amount of super glue. You do not want the wood to separate from the casing when you are turning it on the lathe.
Once you have a good amount of glue on the brass casing, place it in the hole.
Turn the block over and press it against something eflat so the casing fits flush with the end of the wood block.
Let dry for an hour before moving on.
Once this is complete you are ready to put the wood on the mandrel and start turning it on the lathe.
Start the lathe and place it on the lowest speed to shave off the corners of the blocks.
Using a chisel, slowly start to shave off small pieces of wood.
Eventually you will round down the corners and it will become easier and faster to shave more off.
Once you have the wood shaved down almost even with the metal, stop using the chisel.
Get some 80 grit sand paper and sand the wood until it is even with the metal. This will even out any groves made by the chisel and will mke your pens equal width. You can use 220 grit sand paper to smooth out any marks left by the 80 grit sand paper.
