>Best way to not worry about the foot being marked by the chuck is to initially turn the foot a little longer. Then chuck it. After you've turned the bowl, inside and out, sanded and maybe even a coat or 2 of finish, turn off the extra length of the spigot. Voila, no chuck marks.

Duh! [slaps forehead!] But how do you finish off the bottom of the base, then?

1. vacuum chuck

2. Cole jaws

3. Donut chuck

Here is a link showing how to build a donut (compression) chuck.

>Stuart,

Hmmm...that's a great site...I've never seen a compression chuck before. That's the way I'll have to go to fix it, I guess. But the next question is...how do you line the bowl up inside the two separate plates of the compression chuck? Isn't there a fair chance that when you tighten down the carriage bolts the bowl will be off center a bit?

Thanks for the link and thanks for your input...

>You can snug the bolts just tight enough to hold the pieces and then use the tailstock to help line it up. I also cut shallow groves in the piece that is attached to the face plate. Centering the bowl isn't much trouble.

>Mike,

Well, thanks. Good, or in this case "adequate," photography can make things look better than they really are. You're not seeing the scoring and the broken-out chips on the foot of the bowl.

Besides sometimes the wood just is so beautiful it does all the "talking'...if you let it.

Thanks to all for the kind words and advice.

>That's an excellent 1st bowl.

In order to avoid chuck marks, I use a dovetail jaw so that won't bite into the wood. Making an internal tenon well eliviate the problem, too. As of late I just make a rough tenon for the foot and re-chuck it ti finish with a fine foot.

Thanks...

Collecting ideas...how do you re-chuck it?

>On the little bowl posted above I put a larger blank on the face plate and channeled out a little ring just big enough to accept the rim of the bowl. Then I duct taped the bowl to the blank and turned the bottom. I finished the inside and upper outside before I rechucked it and then was able to finish the rest while the bowl was rechucked. Worked for me.

>Don's method is fine. I bought the adjustable bowl jaws for my Vicmarc chuck. This allows me to get ellegent small feet like the bowl in the picture that is from local [Israel] Indian rosewood.

Many pros such as George Hatfield have taken these jaws and instead of using the plastic pegs it comes with and have replaced them with mdf board and cut/score the board to size and use that for reverse chucking.
