I’ve built spline jigs before. Quick and dirty ones. It was time for me to get a more permanent, better built spline jig. Eagle America came out with the Spline Jig Pro a while back, and when it went on sale, I bought it.
Assembly took about 30 minutes, that included futzing with the camera and fitting the miter bar to my miter slot. The parts are well machined for the most part, with any problems being cosmetic and not impacting the accuracy of the jig.
Eagle America has assembly and usage videos on their site.
- Read all the instructions before starting assembly
- Don’t fully tighten screws until you’re done with a sub-assembly
- Be careful using a screw gun, you’re tightening screws into an insert in MDF
- Be careful adjusting the bar to your miter slot – it’s hard to adjust the bar after it’s been installed on the jig
- The short screws (there are only two) are used to attach the miter bar to the sled
- Well placed holes through the cradle and sled would make miter bar adjustability easier
- Make sure your miter slot is parallel to your blade
- Carefully set the angle and height of the blade before making your first cut
- The stop push the stop blocks into the base of the cradle to square them up when adjusting
