I’ve been wanting to upgrade my coping saw for a while. It works but I’d like something with a bit deeper throat. A bandsaw is not in the budget right now and no room anyway. So how about a turning saw? Tools for Working Wood sell turning saws (they call it a bowsaw which is another name for this type of saw). They also sell the blades and the little brass pins you need for holding the blades. I decided to buy a blade sampler pack and the pins and make my own saw.
Joel and the crew at TFW have a nice set of instructions, tips and measured drawings to get you started. I decided to try white oak as I have a small stash of QSWO left from another project. Hickory and osage orange seem to be the two most suggested woods for bowsaws made in the US. Beechwood is the traditional choice. The QSWO is pretty straight grain and should work fine. But if you hear a loud snapping noise followed by some cussing we will just chalk it up to practice. :) Seriously, the key to using any wood for this project seems to be straight grain and orienting the grain so that the quarter sawn faces are on the inside edges of the arms and the flat sawn grain faces out.
I’ve done a few test cuts in some scrap 3/4” pine with the 10TPI blade. It cuts very quickly since the stroke is about 12”. And I can cut a pretty tight curve. I can also loose control of the curve easily. This is a practice issue, it just cuts a little differently from the coping saw I’m used to. My little practice fish ended up looking like Jimmy Durante but otherwise it was a breeze to free-hand a small shape. The Sharpie marker is just for scale in the photo.
The oak has been left somewhat rough. While I did sand the handles down to 220 on the lathe, the rest of the pieces are no finer than 100 grit or whatever marks were left by a mill file. I may go back later and refine the surfaces more but for now I’m digging the more rustic look. It feels fine in my hand and I didn’t leave any sharp edges. The oak will take on some personality with use too.
