radius skew

>I'd like to hear from some of the users of radiused skew. I'm talking about a curved cutting edge. I ground one of mine that way to try it out(several years ago) and I didn't see any advantage at all. In fact I found it harder to use for truing up the ends of blanks with the toe down.

I'm always open to learn more about a tool so hope maybe someone can explain how this is an improved edge.

I've also seen a skew ground with a concave cutting edge rather than the usual flat or convex. Any comments on that. I did use a skew ground that way when I took Don Russells Segmented turning class. He uses the tool as a scraper because all of his bowls are side grain due to the lamination segments he uses. This tool cut with big curls and gave the same finish on that type of bowl that I get from my bowl gouge. I tried both ways just to see.

>pete..

can any skew be reground in this fashion..

or is it a waste of effort???

>John,

At the Turning Southern Style two yours ago, I sat in on several rotations with Ernie Newman, from Austrailia (you probably know him as the guy that does the history trivia in the AAW Journal). He is a skew expert/specialist. I asked him about the Radius Skew. He says that Raffen made it popular, but even he has moved away from it. He says that it works well for planing type actions, but the difficulty seeing the bottom corner when cutting beads, and the difficulty seeing the top corner when cutting V's makes it difficult to use.

I any of you disagree, don't yell at me. I do not have a dog in this fight. I am just relaying the information.

That's exactly what I found. I like to watch those points as I turn beads. I heard that it was better for planing but I couldn't figure out how. With either skew you only have a shaving about 1/4" or less wide. The difference between the radius and the flat skew are minimal for that type of cut.

>Absolutly! In addition, you will also want to round the bottom length of the skew for smoother movement across the tool rest. Personally, I don't just soften the corners, I grind the top and bottom to a full half round. In fact, I have a dedicated 4" belt sander for this purpose (and for smoothing out nicked tool rests).

Yes....and no

>If one is rolling a bead using the short point, then yes, its more difficult because you can't see the point too well. In fact, there isn't much of a point to begin with. However, I find that rolling a bead with the long point is just as easy with a radius skew as it is with a straight skew.

As far as I know any skew can be regound to a radiused edge. You can also gring the bottom edge round or at least ease the corners. I think everyone is in agreement with this.

I'll agree on that point. Where I have the problem is when I'm squaring up the end of piece or when going from square to round on a pommel where I want to leave a perfectly flat edge. I have trouble seeing the point and knowing what it's doing. This is especially true when I arc the tool in from the side going toward the middle rather than arcing it from the top down which is the usual way. I find that arcing the skew in from the side or even slightly below center reduces tearout on even the the softest wood. This is because the angle of the cutting edge is approaching the wood at an extreme shearing angle.

>I use a slight radius on my skews, from 3/8" to 1". Like everyone else I watched the Raffin tapes to get started. I never put a simitar sweep like Richard's earlier tapes. A couple of years ago I attended a hands on with Hisownself. One of the things he did was resharpend everyones tools to suit him. When he resharpened my skew, it came back with a gentle sweep. His own skew had the same gentle sweep and not the radical simitar look as his earlier tapes. Watching that tool in His hands, reminds us of what mere mortals we really are.

I can use either the straight or radiused, but prefer the slight curve. It is much more forgiving and I have no trouble cutting beads or deep V's. I learned to use the skew with the straight edge before I radiused the edge to see if there was any difference, knowing I could always make it straighten it out if I wanted. I never went back to the original grind, only the bevel angle has changed.

>Yes, I do also. I think that it is easier to control. The one that I use most often is 3/4" wide, but I just ordered an Alan Lacer signature version which is 5/8" wide (BO with Craft Supplies).

I guess it all depends how you get started with the skew...and after the Alan Lacer video, I started with the curved skew.

>John, I bought a 1 1/4 inch P&N skew ground the ends so it is now a radius skew. I use it as a bowl scraper for the final touch before sanding. I use a detail gouge to roll my beads.

>I use a mild radius and find it better for planing and bead and coves with the point end down, the curve end making it easier to see the point. I was taught by Dave Regester to take a 3/4" oval skew and cout a radically angled bevel along with being radiused and this allows for making very narrow coves.
