Finger Joint Jig

thingiverse

I was looking for a way to create a precise finger joint cutter using a single blade but had the problem that it would cut twice as wide as my blade's kerf. That's why I designed this jig, which enables me to accurately cut 5.6mm finger joints with a 2.8mm kerf blade. If you're also building an accurate sled, you'll be able to rapidly cut finger joints using my jig. However, keep in mind that my jig requires additional components to function properly. You can print all three parts without supports on an FDM printer. Here's what each part does: the pattern part serves as a reference point for the jig part, which has teeth that engage with the pattern. The spacer part spaces joints on the second piece of timber so they match the ones on the first piece exactly. I've found many DIY finger joint jigs online to be inadequate or inconsistent, and often difficult to use. My design offers a rapid and precise way to create accurate joints. I hope you find it helpful.
