Wow, what a great article!

Do you have any old planer or jointer blades?

Those work quite nicely. You can use a keyhole saw blade, but they aren't quite as nice.

I've used old blades from my DeWalt planer that I've trimmed w/ a Dremel tool.

JL that is pure genius! The keyhole sawblades are terrible.

I made mine some 15 years ago and it still works like a machine. Philip

Exactly what i needed. Didnt remeber the relief cut for shavings to escape.

Thanks JL

I ha e.planer blade and when time allows i will make one with that.

That's now Jennie Alexander, not John.

John, I use my planer knives for scrapers that I sharpen like a chisel, then roll a burr. If I use the Koolmist sprayer when I grind, the edge chips out, so I have to get it red each time I resharpen before it will roll.

The reamers that Tim Manney makes (developed by Peter Galbert, I believe) are similar to the ones in the articl John Aniano provided, with a couple of refinements.

He turns a cone on the top end and sets a small brass point in the end of the cone, to be used for aligning the reamer with the sight lines.

He also sets an adjusting screw in a tapped hole, so it engages the back of the scraper blade, to adjust and hold the exposure of the scraper.

You'll probably need to make one of these, too:

It's a lot easier than trying to match the angle of your reamer to an existing tenon rounder.

Tim also explains methods for sharpening the reamer blade:

There's lots more useful info along the same lines in Peter Galbert's and Tim Manney's blogs, not to mention in Peter Galbert's book, "Chairmaker's Notebook."

Roy was using one on his show last night

Barry Irby

In the one he had the blade was a tapered piece of metal and was loose. The shaft was tapered with a slot and the blade fit loosely in the slot. He drilled the hole with an auger bit in a brace, using a sliding tee bevel to site it in. Then he tapered it, mentioned you could correct the angle of the hole to some extent.

His tee handle shaft did not include any relief on the cutting edges and it clogged quickly. He commented it would cut you so be very careful cleaning out the debris. Seemed to cut on both edges. I though cutting some relief space into the wooden taper on both sides would be good, but I don't know. Maybe you can look up the show somehow.

Would you happen to have noted the Woodwright Shop season and episode number?

Sorry, I wasn't really watching closely and did not think of getting the numbers. Wonder how I could research that?

Welsh Stick Chair 1......

Barry Irby

Season 35 Episode 10 about 19 or 20 minutes in.

That is one ugly chair.

Went to PBS and looked it up. Just started with Roy Underhill in Google.

The chair is painfully ugly to me, but the techniques carry over.
