# The Box-From-A-Block Jig

 Blog entry by Matt Snyder posted 02-04-2019 07:16 AM 1037 reads 7 times favorited 6 comments

This is a jig I made that allows me to make a small box from any size block of wood (within reason). The appropriately sized frame pieces mount to the walnut sliders and the whole jig mounts to my router table.

I was able to route out 13 blocks in less than 20 minutes. I decided to use the live edge slab from chainsaw milling the walnut I used for the sliders.

That scrap slab had some cool spalting in it.

Here’s a YouTube video of the build.

I hope you enjoy and your comments are welcome.

How do you determine the thickness of the box wall?Added to my favourites.Jim -- It always looks better when it's finished! sras4993 posts in 3400 days #2 posted 02-04-2019 04:17 PM Nice jig! Good video too. -- Steve - Impatience is Expensive Matt Snyder16 posts in 24 days #3 posted 02-04-2019 04:30 PM The length of the frame pieces is 2 x (block diameter – bit radius – wall thickness) for a 3” box I use a 1/4” wall and a 1/2” bit. So the equation fills out as follows 2 x (3”- 1/4” – 1/4”) = 5” frame. -- - I learn more from my failures than my successes.
