I thought I'd start with pickguards and such first. I've collected a dozen or so different vintage pickguards (mostly from Eddy Elliott) so that I can make my templates and know the correct hole sizes and positioning. Another method is to borrow a pickguard or control plate from an owner so that I can make the template. I did this with Nate and his Stereo 350 (pictures to follow).
This also allows folks to put away their vintage pickguard and put an exact replica in the material of their choice for a little self expression.
Below is a pictorial of how I did just that with our very own Jim Page. He wanted to put some tortoise pickguards on his Celebrity and send me some cardboard templates. I can't wait to see them on his guitar!
First, let me introduce you to "Celebrity Central". This is one wall of my little "Girl Cave". It's the bench that I use to work on guitars, do setups, etc. It is carpeted and very handy with lots of lighting, etc.

The first thing I do is make oak templates out of 1 X 6 oak that I get from Lowes. I know I could use thinner but I like them being taller and a bit heavier.

I don't have a Drum Sander yet, so I improvise with my baby drill press. I bought these neat little gizmos from a local woodcrafting store. They sell sandpaper tubes that slip over the gizmo and when you tighten the screw it squishes the rubber outward to hold the sandpaper tube. It works really well. I use it to sand inside curves such as the one below. For outside curves and straight areas I have a regular beltsander/disk sander combo.

When I've got the templates the way I want them. I drill some holes, countersink them, and attach the templates to a larger board.

When I make my oak templates I also make matching templates out of masonite (or whatever it's called). I bought a 4X8 sheet which will last me forever! I use the masonite templates to draw my pattern onto the pickguard material. I have different colors of Sharpies to do that. The reason I like the masonite templates is that they are cheap, easy to replace, and I don't have to remove my oak ones from the board to trace onto the plastic.

I know it's not real easy to see in the photograph, but I can see it just fine on the bandsaw.

Then I rough them out on my handy dandy Craftsman bandsaw (found on Craigslist for a steal!).
