Made a Box Joint / Finger Joint jig today.

Have seen several on this site and decided I needed one.

It is 12×12 made from 3/4 inch birch plywood and 4/4 mahogany. Guides are Maple cut offs.

Took several tries to get the joints to come out snug. Ended up useing screws in a loose hole from under neath to hold the Mahogany in place. That way I could loosen them and make micro adjustments to get the joints to tighten up.

Will probably pull one screw at a time and replace with dowels and glue to keep it alligned.

Also put in a picture of my “POOR MAN’S ROUTER TABLE”

Top is cook top cut out from friends corean countertop. The sides are 3/4 inch birch plywood cut offs.

Found out coren is as easy to work as wood. Drilled, and countersunk screws easily. Will have to look into useing more for other jigs. Only problem, only 1/2 inch thick. Not deep enough for T slots. Have to clamp edge guide to table top. But top is VERY smooth.

Hope you all enjoy Thanks for looking.

Good job on the box joint sled, been needing to make one for myself for a while.

Looks like a functional, flat, smooth worksurface that should hold a router steady for years to come. Looks better than many manufactured router tables. Thanks for the idea of Corian counter material. I have freinds in the countertop fab business, they may have scrapes or cutoffs.

Uhhh does your friend know you used his countertop…? ;-)

Looks good, a smoother surface on my table would be useful, I’ll have to start scouting my friends kitchens and wait for them to turn their backs LOL!

How did you drill and mount the router to the granite? I have some scrap granite slabs but I don’t know how or if I’m capable of cutting the hole for the router plate. Also how did you attach the fence to the granite? Love the idea just don’t know how to accomplish.

Jethro80, This is NOT granite. It is Corian. Cuts like hard wood. You can drill and saw and turn, whatever you want to it.

Great Jig Scrappy. Did not know that about Corian. Can you route an edge on it?

Thanks for sharing.

Good Luck!

Thanks scrappy, I didn’t know that about corian either. I do have some nice granite slabs that I’d like to use for a router table but…... I’m not sure I can get the granite milled and drilled
