The Splined Mitre Joint is a decorative yet very strong joint. The addition of the spline and glue makes a regular mitre joint all the more stronger while aiding in keeping the mitre nice and tight. By using a contrasting wood the woodworker can achieve a very distinctive appearance at the joint.

This woodworking video tutorial shows how the spline mitre joint is made using a woodworking jig on the tablesaw.

You did a nice job on the production of this video, Bob. Your process is clearly documented and straight-forward to follow.

Great stuff – the video was (again) nice and clear.

Hey, how about testing out those new sketchup skills with a table saw spline jig posting?? :)

A question for you – how thick would you create a mitre joint before going ahead and adding a second (or third) spline? I guess I’m thinking about box making here rather than picture frames but at some point the added strength vs. decoration factor must come into play. Do you have any tips?

Thanks again.

MG…
The spline mitre jig is on the burner. I’ve got to work on that, however I’ve got some great support for SU. My plan is to have a jig available and hopefully before long. Good question!

“how thick would you create a mitre joint before going ahead and adding a second (or third) spline?”

Example: Let’s say you’re making a small to medium size jewerly box and the 4 sides are joined as mitres. In this case I would definitely have a spline towards the top and also towards the bottom of each mitred corner. In this case I would use an 1/8” dado that has a teeth that will produce a flat cut. If you have a saw blade that produces a flat cut instead of an alternate bevel then that will work too. This way the spline will seat firmly against the inner part of joint with having any gaps.

An 1/8” spline with glue will greatly improve the strength of a mitred joint. Make sure the spline is deep enough, but not TOO deep. For layout of the spline mitres…use good judgement as far as what is appealing to the eye.
If the box is larger…then increase the scale of the splined mitres as well. Think in terms of proportions and use your eye for judgement.

Consider making a practice run before you commit to spllining your finished product. Test it on a scrap joint. If you make a mistake or it’s not just right…you’ve lost nothing, but only gained experience. Dial it in and get comfortable with the process. Then when you’re ready fully commit.

Thanks for the advice! Looks like it’s about time to invest in a good dado blade set.

MG…You’re welcome! A good dado blade set is a good thing to have.
