Rocker Mortises with Domino DF700

[Crox G]

I’m making a child’s Windsor rocking chair for a great-niece.  I’ve always had trouble cutting the slots in the legs to receive the rockers, cutting into maple end-grain. Alignment, chatter, vibration, and chiseling are always a pain.

The rockers are a bit over 10 mm thick.  I tried a couple of test cuts with the Domino set at 25mm depth with a 10mm bit.  In order to line up the mortise with the other leg, I laid a rule across both legs, and rested the fence on it.  I set the fence height to half the leg’s diameter plus the thickness of the rule.

A careful plunge made a nice slot in the leg, with just a little to saw and shave for a good fit.  Here’s a picture with my left hand removed for clarity.  You can see one of the mortises in the near leg.  My apologies for the clutter.

As a sweet bonus surprise, I could put a Domino in the mortise and use it to guide the thin-kerf Japanese saw.

Nice technique with the ruler. If the mortises need to be a hair wider than 10mm, you can stack some playing cards between the leg and fence as it will be more consistent than changing the fence height by hand.

That was very clever, I like it!

I love outside of the box thinking  [thumbs up] Very cool.

That's very clever and a nice setup with the rule. I'm glad to see that your left hand was, in fact, only removed from the process and not from your arm.

Love the look of your workshop
