Topic tags/keywords: question cherry joining box joints drawers

Forgive me if this question has been asked and answered before, but is there something special I need to know about cutting small box joint pins in cherry?

I’m in the process of making drawers for a cherry jewelry chest for my wife. I tried 1/4” pins with 1/4” x 1 3/4” stock, using a dado blade to cut the slots, but the cherry splintered badly. Is 1/4” too small for cherry, or is there a trick I can use to clean up the cuts? At this point I’m considering cutting them with a fine tooth pull saw and cleaning up the rest with a chisel. Honestly, however, I’d really rather find a faster way to do it. There are 6 drawers and cutting 24 sets of pins by hand is going to take a while.

Thanks everyone, for any and all suggestions and feedback. I love this place!

It sounds like you either don’t have the cut supported well or a dull dado. Cherry can blow out fairly easily, but if you support the back of the cut, you should be good.

If your box joint jig has been used previously to cut wider pins, your narrower cut now isn’t adequately supported due to the wider slot behind it. I’d consider trying to affix a backer board to support the entire cut or make a new jig specially for 1/4” pins.

I hope this helps. Good luck!

One more thing; clamp the stock firmly to the jig as you cut slowly. 1/4” stock can bounce around a bit, causing a less-than-clean cut.

Could always try an Incra jig with a table mounted router. There are lots of jigs you can use with a router table.

Make one of these jigs specifically for your application, out of red oak to properly support your cherry and you should be fine. Also, I use blue painter’s tape on both sides to support the fibers while machining.

Commajockey: I think it’s a combination of all three of your points. I used my crosscut sled as a base and CA glued a 1/4” key in the proper position. But I know the vertical slot was taller than I needed for my piece. That, combined with the fact I didn’t clamp it securely to the fence most likely accounted for the bulk of the problem. My dado is a Craftsman with a factory sharpening job. I’ve only used it a few (3?) times, but I’m sure if I had it sharpened it would perform better.

DaveR: Thanks for the stacking suggestion! That would really cut down (no pun intended) on the repetitions and improve consistency of my cuts. Great suggestions all! Thanks a ton guys!

You bring up an interesting point, Dave. Does cherry react better (for a lack of a better way of saying it) to a router bit than a dado blade, or vice versa? Or does it make any difference?

Right! That much I’ve definitely learned on this project—the HARD way.

I think a spiral bit in the router would be the cleanest cut. Just my opinion.

Very simple jig here: http://www.woodworkingchannel.com/dolphin/videgovideolibrary.php

Go to the router workshop and check out the “desk set” he explains it very well. I made mine from that.

Hope this helps.

Scrappy – Thanks so much for the tip on the spiral bit! I picked one up and tried it out—the cuts were perfect! I’m still working on dialing in the spacing for the fingers, but I’m close to getting it right.

Thanks again all!
