In the infancy of my woodshop, back around 2010, I realized that I badly needed a scroll saw, but sorely lacked the funds. Using what I had available to me at the time, I was able to create a fixture that firmly secured my Black and Decker jigsaw, essentially turning it into a functional and versatile scoll saw. This is still one of my primary tools still utilized in my shop, and I've churned out some high quality projects with it.
What you will need:
- A jig saw (obviously)
- A hand saw or circular saw
- Scrap lumber that best suits your needs
- A Dremel Trio (not necessary at all, but makes routing the hole a bit easier)
- Wood screws
- A drill press or drill gun, along with assorted drill bits
- Some sandpaper (not critical, but no one want's splinters everywhere).
Step 1: Make the Mounting Surface and Saw Blade Hole
Using my jigsaw to gauge the relative location I wanted to mount it in, I marked where the saw blade would stick out from the mounting surface, and gave my self some clearance, let's say no less than 0.375" in either direction about the blade.
I then used my Dremel Trio to create a rectangular hole that fit into my markings. Alternatively, this feature could be made by drilling a 5/16" hole in each corner of the rectangle, and then using my jig saw to cut between the four holes.
Either way works fine, just depends on the tools you have on hand and how good you are at using them.
