Making a (Very) Small Dovetail Saw
I recently restored this 1840-ish British 10” dovetail saw made by Richard Groves & Sons. I like the saw so much that I decided to make a copy of it.
I’ve made quite a few saws, but I’ve never made one like this before. My newly made saw is a 0.60 scale copy of the Groves saw, with only minor differences.
Why, you may ask, would I spend the time to make a saw like this? With a blade that is a mere 6” long and a handle you can only fit one finger in, the thing isn’t even useable, you might think. Well, my reasons for making this saw are simple. First, I thought it would be a fun project, and now that it’s finished, I can say that it definitely was enjoyable. Second, I made this saw to challenge my skills. It is generally a lot harder to make a miniature version of an item than it is to make the item itself. That was true in this case, particularly the cutting and sharpening of such small teeth. Overall, though, the saw was not tremendously more difficult to make than a full-sized saw. It took about the same about of time, but it certainly took less materials!
The brass spine for my little saw is made from a piece of ½” brass angle. The legs of the angle were bent together in my bench vise and then shaped on a large belt sander and with files. Finally, it was polished with sandpaper down to 600 grit and then buffed with 0000 steel wool.
The plate is 0.015” thick 1095 alloy spring steel, the same thickness I use for making 8” gent’s saws. It also is polished to 600 grit. Cutting the 20 ppi teeth was probably the hardest part of making this saw. I’ve sharpened teeth that fine before, and that alone is a challenge, but cutting new teeth this small takes the challenge to another level. With the aid of magnification and a needle file, though, I’m happy with the results achieved.
The handle shape is an exact copy of the English beech handled Groves, but Brazilian rosewood was used instead. This wood is no longer available in the U.S. due to import restrictions. I have a small pre-ban stash rescued from my Dad’s musical instrument shop after his passing.
The split-nut style screws are re-made from antique screws salvaged from an old non-repairable saw. The 1/2” heads were turned down to 3/8” and thinned. The screw shafts were cut down from 7/8” long to fit the ½” thick handle, and re-threaded to 8-32. I made new 3/8” diameter split nuts to secure the screws.
I’ve seen miniature saws before. In fact, I have a little backsaw that is under 3” in total length. But these saws are novelties, not intended for actual use. My new little backsaw is a real saw in every sense of the word, it’s just small. Is it too small to use, though? I’ll admit that grasping the tiny handle is a bit awkward, but if you can manage it, the saw cuts every bit as well as a larger one. Tiny dovetails anyone?
This saw won’t be among my primary users. Rather, it will be displayed as a conversation piece. Whatever its fate, I’m glad that saws come in all sizes.
