wall thickness

>Here's a question that is puzzling me. Sometimes I see bowls or other hollow forms that are relatively thick walled. A bowl 12" wide and 6" high or a vase 12 inches high and 8" wide...for two examples of items I've seen recently. The walls of each were 1/2" or thicker in each case. The vase was a burl with some open inclusions.

My question is this: is thinner better? I would think that you would want the walls of any vessel to be as thin as possible...within reason and keeping in mind the strength of the wood. But what is reasonable?

BTW, thanks to all who answered my question about first hollowing tools.

>I've never been much of a fan of extremely thin bowls or vessels. For one thing, I'm not that good. I have seen bowls that had wall thicknesses down to 1/16" or maybe less. (Think potato chips.) Beyond being able to show all your friends that you have the skills necessary to produce such a creation, I can't think of much practical use. More important, I think, is uniform wall thickness. What's reasonable? I say 1/8" to 1/4". For a larger vessel or bowl 3/8" to 1/2". But, that's a matter of personal preference.

>Depends! (as with all things)

I'd say it depends on the choice of wood, the intent of the piece, the desire to show off one's abilities or to appeal to a target audience.

I've done hollow forms with a few voids down to about 1/64" thickness, but it was to show off. Most of them are about 1/8". Vases? Depends on what it is for. I have a salad bowl posted presently that is probably 5/8".

Oh it all depends. No set rules as far as I can tell.

>Most of my work is in the 3/8" range. Yes I can turn thin but so what. I find that most buyers want something that feels good and looks good. Most of the time if I have a thin piece the buyers will pick it up and quickly put it down. My primary product is usable bowls with about 20% display forms. Most of the display work is a little thicker and weighted to the bottom to provide better stability.

Good turning and be safe

>The answer is,the wall thickness should be consistant and appropriate to the form.

Thin walls will impress other turners but seem to scare off buyers.Most customers tell me that a light bowl seems too fragile to use.There is also the impression that more mass(where appropriate)means more value.

Some of the burl pieces I turn that have alot of voids need a thicker wall(3/8+) in order to stay together.The form on these pieces are mostly squat and look visually heavy and massive

Afew of the pieces with insect holes that are otherwise sound I turn to 1/16th or less so the holes will be pierced thru.These forms are uplifted and look like they can float away.

In each case the wall thickness/weight of the piece is appropriate to the visual impact of the piece.

I finish turned a piece of birdseye maple recently that had some large eyes and excellent curl thru it.It also had two bark inclusions running parallel to the grain.This rough (with 3 inch thick walls due to the inclusions) was soaked with CA at the bark and had sat on the shelf for 6+ years before I felt it has time to return it to the lathe.Thinking the glue would hold it I turned a short,squat closed form and was originally going to hollow to about 1/4 thick wall.

When I began to work on the inside I noticed the eyes looked like bubbles rising thru water in the side grain.If I hollowed as I had planned I would lose that figure.The piece ended up having 2"+ wall thickness and was VERY heavy both visually and weight wise(they don`t call it rock maple for nothing).It was a first for me and I figured if it didn`t sell at the gallery I could always just hollow it and sacrifice the figure I was so fond of.It lasted 3 days at almost twice the price of my utility bowls.

Just when you think you`ve got it all figured out,along comes another curve you never saw coming.

>This is a very interesting thread!

I was kind of leaning towards the opinion that (up to a point) thinner was better, simply because it is more refined. Then too, except for the obvious--salad bowls, etc.--most hollow vessels end up being display pieces rather than utility pieces. So, again my, admittedly amateur, first impression is that thinner is more "artistic."

But I am hearing some ideas that make me kind of doubt that intitial assessment.

I wonder if some of you could post photos of formes that would be appropriate for a thick wall and formes that are more appropriate for thin walls.

Many thanks...

>As soon as the person who was working the gallery comes back from traveling I plan to track it down(hopefully it was a local person who bought it)and take a picture of it.I thought it would be around for a while so the digital photo/webmaster guru at the gallery didn`t get a pic of it.

Come to think of it you can see some of my work at www.saltrivergallery.com,just click on owners then click on my name.
