Best ruler for the ruler trick?

[Martin S.]

Looking for recommendations for the best ruler to sacrifice for the ruler trick.

Thanks.

Thinnest one you can find.

+1 on what John said - a piece of sheet metal will work as well.

I was going to suggest PTFE tape, but the old Boeing Surplus spoiled me. If you have an HF near grab the cheapest, thinnest rule. Maybe shim stock.

I use one of those flexible pocket rules, like the ones you can get with a clip that fit in your pocket.  I think they are sold in nearly every hardware / big box store.  You can ditch the clip.

What Mr. Hill said.  Look for the General Tools display at any Ace or True Value.  The little rulers are a less than $3.00.  Lie-Nielsen has them too with their name engraved, if you want the real deal.

Use the same as above....

I just saw Charlesworth's video on this last night on youtube. He specified that his ruler is .5 mm, which yields a back bevel of one and a half degrees, I think he said. The video also shows correct technique. you can't draw the plane blade too much up onto the ruler, or it will have a ramping effect that will increase the back bevel. He was taking tiny little swipes, maybe an inch forward and backward. Recommend searching youtube for the video if you're gonna use the ruler trick.

The ruler described by Mr. Hill and Mr. Brady is the one I have always used.  (It is important to use the same one always).

The ruler is narrow and 0.5mm thickness gives a back bevel of approximately 2/3 of one degree.

(I have about 1 1/2 degrees of clearance angle on the front underside edge of my chipbreakers).

A short stroke is used, just off the edge of the polishing stone , to no more than about 10 mm onto the stone.

Some of my friends prefer to use a stroke along the edge of the stone.  ( I worry about creating some crown!).

I now have a small you tube channel.  If you search David Charlesworth Wood, you will find it.

A video clip of the ruler trick in action is there.

The name alone finds a German porn star.........

Best wishes,
David
