>Very nice Dominic! I knew you would get to that maple before me. Mine is still sitting in several rather large lumps waiting to be cut up. Now I know what to expect with it. IT is too bad I have all this flat stuff staring me in the face. I would love to get in the shop and turn turn turn. Keep up the good work!

>More great work Dom. Makes me want to get pics of my most recent S. Maple bowl up. I love that stuff. Just can't get my hands on nearly enough.

Turn 'em round,

Re: technique question

>Dom, a technique question: How do you hold a natural edged bowl, after you've finished shaping and polishing the inside, so you can finish the foot? Bill Grumbine's jamb chuck won't work without damaging the bark edge. Now that I have finally acquired a scroll chuck and some of the other tools I need, I think I would like to try a natural edged bowl.

Jam or vacuum chucking

Dominic Greco in Richboro PA

>For small natural edge bowls, it's really pretty easy procedure if you have a vacuum chuck. I made a small vacuum bell from a 2" x 3" PVC reducer. The bell is held by in a Talon chuck.

When the natural edge bowl is deep and the opening too narrow for a vacuum bell, I have to resort to a jam chuck. Just this past Saturday I needed to finish off a deep natural edge hollow form. The vase/hollow form was way too deep to use the 3" dia. vacuum bell held in my Talon chuck. So I turned a piece of 3" square x 7" long sweetgum down to a 2 1/2" dia cylinder. I turned a tenon on one end, and chucked this into my Talon. I then wrapped the other end in a scrap of non-skid pad (the kind they sell for router work). Trap the bottom of the vase between this contraction an the tailstock, and you're good to go.

See ya around,

Dominic

>Thanks, Dom, the clouds are slowly dispersing.

A vacuum chuck is still quite a ways in the future for me, so the jam chuck is what I think I need to use. I still can't see how you get the bottom completely smooth, without the point of the live center leaving a mark in the middle of the bottom. I think I understand that you use the jam chuck only while you are removing the tenon that you used to hold the bowl in the Talon while you were hollowing it. Is that right?

I have stuff that should work well on the end of the jam chuck, but I don't have a feel for how closely the shape of the end of the chuck needs to match the shape of the bottom of the bowl.

>If you really need to access the entire foot of a natural edge bowl just use a compression chuck after mounting the bowl as Dom suggested using a post and pad.

The end of the post does not have to be the same profile as the inside of the bowl.Mine actually are slighty dished so they make contact along the outer edge.

I mount the piece in the compression chuck,center it and get it running true with tailstock in place.Turn most of the foot with tailsock in place for safety,then when access becomes a problem,or the stub gets too small,I move the tailstock away and turn just using the compression chuck.

The best thing about this approach is that it works for forms with voids or borer holes and works for ultrathin walls that would crack under a vac chuck`s power.

Let me know if you need more info on this particular approach to skinning this cat.

Nice to see you on this side of the island Sir William.

>Hi William

As Dominic mentioned, there are a couple of ways. If you check out the article on my website on turning a natural edged bowl, you can see pics of how I do it when a vac chuck won't work.

Here is a picture of the essential setup. This might be a good demo topic for the picnic, eh?

>Thanks guys,

That was quite helpful. Now that I have a Talon, a screw chuck and a couple hunks of burl, with this little bit of knowledge, I just might be getting into dangerous territory. I think I'll try Bill's illustrated method first, and if I'm not happy, I could build a compression chuck and install a jam chuck inside of it.
