Fortunately, there's no need to go out and buy one of those kitschy pumpkin carving kits - you can make your own saws that perform better and cost less money!
Step 1: Tools and Materials
3/8" - 7/16" wood dowel (I used poplar because it's inexpensive, but it really doesn't matter)
5" scroll saw blades, 15-20 tpi (teeth per inch), pinned or unpinned ends
JB Weld or some other high-strength epoxy
spray paint (optional)
For the jigs, you'll need some scrap pieces of 2x4 and some wood screws.
The required tools are also pretty basic:
A wood saw (I used a scroll saw)
A drill press (preferred, though you could do it with a hand held drill)
