Like most woodworkers today I don’t have much money in the budget for new tools, unless they are absolutely necessary for a project. My last project was going to need some biscuits and I don’t own a biscuit jointer. Since I can’t afford the P.C. Biscuit Jointer that I want, I opted to purchase the #1901 5/32” bit from Whiteside with a 1/2” shank. I did not like the idea of simply running the bit in to the 1/2” cutting depth and then just coming out when I finished the cut. I felt that this would leave a gap where the joint would be weaker since it would potentially just be filled with glue.

I got to thinking, how do I make this cut the same as the biscuit jointer would? Then it came to me. The biscuit jointer uses a 4” blade, my router bit has a 1/2” cutting depth so I’ll need a 3” circular guide for the bearing to ride on to make the right cut.

After figuring that out, this is what I came up with.

To keep it from moving around while cutting the slots I added some 600 grit sandpaper to the larger face. Double sided tape could be used instead. I also added the notch in the center so that I could see where my layout lines were.

Scrap lumber to make the jig, $0, router bit from Whiteside $20, building furniture that will last a lifetime, priceless!

Thanks. This was drawn in SketchUp. Drawing in SketchUp is much easier than drawing on paper. You should give it a shot! Try searching in lumberjocks for SketchUp and you will find some great tutorials.
