For many years I was happy with my Olson coping saw, which I bought from the now-vanished Aufdenkamp Hardware in 1996. The saw locked tight. It held the blade without rotating. And when armed with Olson-brand blades, the thing cut smoothly and quickly.
A few years ago, the saw began to tick me off. I couldn’t get it tight enough (even after stretching the frame). The blade holders would rotate in the middle of the cut. It was as bad as my junky Craftsman coping saw from elementary school, which has never worked.
I switched to fretsaws for a while, but I snapped a lot of blades (more on fretsaws coming soon).
This week I took a close look at my Olson, plus a second new old stock Olson that woodworker Carl Bilderback had given me. It was considerably older than mine and seemed to hold blades better than mine. Why did mine stink so bad? I took the saws apart to investigate.
It was the wave washers. The Olson saws come equipped with two wave washers , wavy discs of metal , that help the saw keep its setting when you apply tension. The wave washers on my saw were now lake washers (meaning they were completely flat). So they weren’t doing Jack buddy to tighten up the blade mechanism.
So it was off to Home Depot to pick up some different washers. I tried some 5/16″ toothed washers, but those things did as much as the flattened washers. Then I tried the traditional split lock washer. That did the trick. I put one lock washer between the handle and the frame, and a second lock washer between the frame and the blade holder at the toe.
Now it is better than new. And souping up both saws was about 50 cents.
If you have an Olson saw, this is a great little upgrade. And if you don’t have an Olson saw or blades, you can remedy that at ToolsForWorkingWood.com.
