A spline cutting jig from plans by BradNailor (David), Thanks David! David's blog has the Sketchup plans, a good place to start.

Nothing magic here, just a solid jig made out of some surplus ply I had laying around. A rockler track and couple of t-bolts and knobs with two sliding stops make it pretty versatile.

One thing learned is use a blade that produces a flat bottom kerf, usually not a combination or ATB blade since most of these leave a rounded kerf. Great discussion of the best blades to use for cutting splines is here.


Update: Brad_Nailor’s Project post MDF Miter Spline sled is excellent also, has several good pics of his original jig.

I made a jig like that out of need last week, now I see how to do it right—I believe my work is cut out for me tomorrow.

Nice job. I just finished the same jig today but without the track. I will want that on my next effort.

Love the jig. But I must be the worst Sketchup/Lumberjocks user ever because I don’t see any sketchup plans on brad’s project… lol

That one looks sturdier than mine ! It also looks simpler to operate with the track and pair of knobs thanks for the photos, now I’ll be off to modify me jig…. hope you have a good new year…

Finally…..................a spline jig that I can understand. This is a great piece and one that makes sense to me. Versatility built into the jig itself.
