5 Bowsaws Later

5_bowsaws_IMG_6015

I leave for Germany in a couple weeks to teach classes on making Roorkhee chairs (piece of pie!) and bowsaws.

Yup. Making bowsaws. You’ve probably seen my international treatise on bowsaws: “Bowsaws: An Anthropological View of Three Sticks and Some Cat Innards.”

No? Well that’s because I haven’t written it. I’ve used and owned many bowsaws and frame saws since I started with Popular Woodworking in 1996 – we had a big one powered by a band saw blade – but I’d never made one from scratch. Until last week.

My German hosts at Dictum GmbH asked if I could teach a weekend class on making a bowsaw. As I can drill holes, cut wood and rasp corners, I said yes.

But last week I panicked. I didn’t want to copy one particular design (like the one from Tools for Working Wood) and I wanted the saw to be easy and fun to build. No wacky blade keepers or kooky curved stretchers.

So I threw myself into finding a design that I really liked and tried to work out the kinks in construction. Now, five bowsaws later, I am close.

Thanks to sawmaker Andrew Lunn, I found some curved cheeks that I really liked from a vintage saw he loaned me. Thanks to Tools for Working Wood, I got some simple hardware that is easy to install. And thanks to my little offset gauge, the saw’s frame is easy to make.

What’s an offset gauge? It’s a shopmade tool I’ve had in my kit every since I made my first Welsh stick chair. It’s a way of scribing a line a certain distance away from a curved edge. The real magic to the gauge is the fact that you have two 1/4” dowels that follow the curvature of your work and keep your pencil steady and on one point as you move the gauge. It’s a fantastic way to draw in curved chamfers on a chair or saw frame or anything shapely.

You can make these marks by eye, but a little offset gauge makes the process foolproof. And you then have crisp (not vague) lines to work to with your rasp.

Tomorrow I have to turn handles and make a toggle for this saw. But now that I have the frame roughed in (after five attempts), it should be no problem.

    Love the bow saw idea. I’ve often thought of making one ever since i saw Tage Frid using one back in the 70’s
    at RIT. Maybe someday… :P

    Duh! I’ve been making boomerangs for 25 years, and this is just the tool I need for marking out the airfoils. So far, I’ve used my fingers as a fence to guide the pencil, but your gauge looks foolproof indeed.

    Thanks for sharing!

    The williard anderson saw was a real study in bowsaw engineering and beauty. How (and why) is yours different? Forgoing the sliding toggle nut? the tapered pins?

      It’s simpler. It’s something you can build in two days, even if you’ve never held a rasp before – easy transitions and curves. And simpler hardware.

      Mine should last a loooong time. But if it doesn’t, Bill Anderson’s will fix it.

    Hi Chris,
    I made a bow saw from the TFWW plans and kit and I love it. One problem I had was getting the “winder” the right length so it wasn’t too long to take the last tension needed for a singing blade or too short so that, when in full tension it didn’t slip off and rap my knuckles. To solve the problem I made an oval bobbin grooved for the twine and a 1/2 inch square hole. I then shaped a piece of walnut into a 1/2 inch square by about 5″ long. This is a tight sliding fit in the bobbin. Now when I tension the blade I slide it through the bobbin so it spins free and when it is tight enough I slide it down so that it rests across the full with of the cross bar. My knuckles love it.

    I am now officially excited about building a bow saw (aka turning saw). Definitely got it on my ‘to do’ list as soon as I get my wood working storage licked (working on it!!), build my first ‘real’ work bench (as a prelude to building my real, real workbench using a hunk of laminated 2-1/4″ thick maple) and finish the plaster board on the walls in my wife’s work room. Guess which task has the highest priority?

      1) Mow lawn
      2) Trim same
      3) Take out trash
      4) Anything else SWMBO asks/needs
      5) Projects for SWMBO injected on any given day
      6) Projects for SWMBO’s mother/father/sibling/friend/acquaintance
      7) Home repair/maint
      8) Makes no difference you’re never going to get this far
      9) Projects you hope to accomplish
