This week I’m building a simple spline jig. Plans are available on my website almfab.com/plans

This jig can be built in less than an hour with plywood scraps and works on any table saw or router with a fence. Splines reenforce miter joints and they look good too. I use them in my shop on picture frames and decorative boxes.

Big thanks to long time supporter of my channel, Rockler!

Note because I have a 3 hp saw I use “ industrial” 1/8” kerf blades. If you have a lower power saw you'll want to use "Thin Kerf" Blades.

    It's the little things like, how to cut the spline avoiding cracking that I really appreciate. So much that I would love to see you using the dust mask at 12:20 when sanding, so you're around making this excellent content for ages. Respect on the great video.
  • @Motocicleiros
    Loved it. The corner splines give a very classy and professional look to any project. And this jig makes this task a breeze. Thanks for sharing!
  • This is the best spline jig video I’ve found. I have a non-standard fence so this is perfect. And the Rockler piece will be in my shop soon. Thanks!
  • @BMSculptures
    Love it. I definitely need to use this for some upcoming projects!

    Just built the jig from the plans and I have one suggestion! For people using this with a router table I would recommend using 1/4" plywood as the base instead of 1/2" plywood, as routers can't reach up as high as a table saw blade. I had to extend my router bit up from the collet higher than normal and got some predictable chatter as a result. I ended up using a mortising bit to take a quarter inch off of the bottom of the jig (and used a 1/4" piece of plywood to stabilize it as I got more than halfway done) and now it works perfectly!
  • thanks for the heads up about splitting the splines when trimming, good tip! Yep, I remember the Murphy Bar, hope you do too! [not using it too much lol]
  • @JimOHalloran
    It seems that the evolution of all woodworking/maker Youtubers is to have a Dewalt contractor's saw, then later to get a SawStop. You've done it, Tamar and Wesley Treat both did the same.
