What Are Some Alternatives to Raker Toothed Saw Blades for Making Miter Splines?
Asked by CraftyBuilder42
I'm currently building a box with mitered splines, but I've hit a snag. All my saw blades have bevel teeth and lack a true rip blade, so the grooves I create end up shaped like a V. I'm considering some alternatives: 1) Getting a raker toothed blade, but it seems like a limited-use tool. 2) Investing in a rip blade but I'm worried about potential tear out with walnut. 3) Using a jig with a 1/8 straight bit on the router table, though that feels risky for precision. 4) Trying a single blade from my dado stack, despite not being designed for solo use. 5) Just using a regular blade and applying folded sandpaper in the cut, though I'm cautious about ruining my clean edges. Any suggestions? I suspect the first option is the most practical, aside from getting a rarely used blade.

Honestly, getting a rip blade is the way to go. It's something you’ll end up using more often than you think and it’ll make your spline cuts much cleaner. Plus, the tear out on walnut isn't too bad if you set everything up right. Trust me, it’s worth the investment.

For spline cuts, I typically go for a router with a 1/4” spiral bit. I buy my spline wood online or from Menards and it cuts really well. Sure, it sounds a bit intense, but it gives you a clean finish. You could also use a 1/8” bit, but I find the 1/4” gives a nice, chunky look to the splines.

I’ve had great luck using a 32 tooth flat top grind (FTG) blade for cuts like this. I don’t use it every day, but it works well for joinery. Just be careful if you're using an underpowered saw; a thin kerf might be better for regular rips. You’ll get the hang of it!
