"Fishtail" Box--A Jointery Experiment

Project by danriffle posted 437 days ago 1827 views 6 times favorited 24 comments Add to Favorites Watch

This was a technique I’d been wanting to try for a while—sort of a round dovetail that I dubbed the “fishtail”. It took a bit of setup to be able to cut the joints and they are far from perfect on this first attempt. However everything did line up okay, though some sanding was required to get some of the pins and tails to fit together. And, I didn’t cut the pins quite deep enough—as you can probably see in the pictures they are about 1/32 to 1/16 below the sides of the box. It’s not glued and holds together VERY firmly. I think I’ll leave it that way over the winter to see how much it loosens up.

The woods are cherry and birch [edit—oops, that’s Poplar] (the bottom, which you can’t see, is a scrap of pine).

Next, will come a chest with “Fishtail” drawers.

That’s different – nice job – how about a blog so we can all give these a try?

That’s a pretty cool look. I would also be interested in a how to blog.

Okay, I’ll work on a “How To”. I’m setting up some better jigs as the initial setup was a bit scary at times.

That is a neat look – I would like to see how you do it too. I like the way you used two different colors.

Cool experiment Looks similar to the Leigh “Bear’s Ears” scheme. Like everyone else, I’m waiting for the messy details.

Neat.

I don’t know how it was really done but the pins could be cut using a plug cutter (the non-tapering sort) in a drill press and then a bit of hand work to clear the waste. I can imagine a jig that would fit on the drill press table with some arrangement for incrementing the work. The holes would be drilled by forstner bit to match the plug.

This is a cool joint. I have a Route-R-Joint jig at home that allows similar joinery. You lay one piece flat and cut it on a template with a 1/8 inch vertical spiral upcut bit. Then, the joining piece gets turned 90 degrees where the endgrain is parallel with the table and you cut it with the same bit on a “reverse” matching template. It works good as long as you pay close attention to the setup. Nice job, I like this joint.

One more vote for a blog on how to do this. They look very interesting.

Makes you wonder if the fishtail may be less prone to causing spliiting as there is less of a stress point like a conventional joint?

Any ideas?

I’m going to venture a guess on the pins. A standard round tenon cutter on the ends with thicker stock, then plane it to final thickness and establish the flats?? Pretty neat looking however you did it.

These are very cool. Let me lend my voice to those calling for a blog- I think these would be really neat on a music box for my nieces. Nice job.

That is really different, but I like the idea! I would love to know how you set it up.

Great idea for something new. Imagine opening a drawer on a piece of furniture and seeing that.

Pretty cool. I also want a ‘how I did it’ blog.

I think it might be easier to always cut the depths a little too deep and then trim the protruding tails with a block plane.

Good job,
Steve

Yes, yes! The “How To” is coming. I cut some stock to size last night and I’ll set everything up to mill the joints this weekend and post it all next week. I really didn’t anticipate this level of interest—THANKS!

By the way, DaveR & Doug S, you’re on the right track.

Interesting and unique . I ‘m guessing you used a tenon cutter with a stop system and marked your joining piece and then drilled them out.

This is pretty far out.

The surface area of your joints must be astronomical – I wouldn’t be surprised if it never needed glue.
