Lucas beading tool in use

OK I won't hide my beading tool. I think it's similar to Wally's except with about 30 or 40 years less experience. It's a Thompson 3/8" detail gouge. This mirror was made up of scraps from a local company that used to do custom wood interiors for vans. I glued enough scraps together to get a handle and mirror body. Pain in the butt doing that and trying to get it aligned properly.

The handle was the hardest thing I think I've turned in a long time. Somehow the glue joints must make it more flexible than most woods. I left it extra thick and still had a nightmare turning this. You absolutely could not put any pressure on the bevel at all. I was trying to stabilize it with my fingers like I usually do on spindles half this thick and still had trouble. Also either the glue joints or the different texture of the walnut and maple made it burn my fingers.

I usually turn a handle in about 15 minutes but I barely got this one roughed to round in 15 minutes. You had to take the tiniest shavings and if the tool wasn't razor sharp it still chattered. I think I sharpened my rough out gouge 4 times trying to get it done. Usually I can turn 3 or 4 handle before I have to sharpen that thing. Same was true with the thompson detail gouge. I would turn about 4 beads and have to sharpen. I turned then entire mirror head with the spindle gouge without sharpening and no problems.

Anyway it came out pretty good.

A beautiful piece John. The result is well worth the effort required to turn the handle. I am curious what mounting method you used for turning the handle. I have been pondering the possibility of posting the results of some analysis and experiments that I have done recently on the performance of the various mounting methods.

Mounted between centers. I use a 3/8" 4 prong deive center and a up center in The tailstock. I reduce the pressure on the tailstock to help prevent spindle whip. Mounting in a chuck would reduce whip more but also use more wood. I normally can turn a 10 1/2" spindle that is tapered down to 3/8" on both ends and will have less whip than this did and it's thinnest part was larger than 3/8"

Mounting thinnish spindles in a chuck, rather than between centers, made a BIG difference for me. I thought that was your idea (?).

Are my eyes crazy, or are those beads on an angle? Or is it a warped camera image? I like the effect and am thinking about how to do it.

When i turn my ornament finials i do use a chuck. Not just any chuck but a Vicmarc with the heavy duty extended jaws. They are tapered like a pyramid and very solid. I was doing demos one weekend at the Craft Center on their lathe and a Oneway chuck with 1" jaws. I kept fighting chatter worse than normal. The next day i brought my Vicmarc chuck and the chatter went away. I still had to support the turning with my fingers but it was easily controlled.

I don't usually have a problem on my mirror handles and can turn them quite thin just using my fingers to control the chatter. Not on this glued up handle. I think the problem was the pattern of the glue up. I was turning against the grain and the walnut was softer than the maple which incrased the chatter.
