Yep. That was my exact question. :ROFL:

I didn't know that you could remove jaws from the C-clamp
jaws. Never used them. In any case, I found a useful
set of directions for making a pair of hardwood extended jaws
that you can use in a 4-jaw chuck:

Ah, yes. Most, if not all, 4-jaw self centering chucks can operate just fine with 2 jaws removed. No problemo.

But be careful with wooden jaws. Briar is a very hard wood, and you generate a lot of torsional stress on jaws when boring a tobacco chamber - stress I'm not sure that a set of wooden jaws could deal with, even if they're made of crotch apple or something. That, along with vibration cause by off-center turning, along with the speeds that you want to use for shaping bowls and shanks, leads me to think that wooden jaws are pretty risky for pipe making.

If you try to use this for turning a pipe, your untimely death--or at least a very significant permanent dent in your face--is a very likely eventuality. Notice he is either surface turning items, or using a dead center in his tailstock to steady the material. You will be doing neither of these things. The centrifugal force created by turning an object off-center, four inches out from the point at which it is held, coupled with the lack of a steadying point at the tailstock and the probable insignificant weight of your lathe add up to a very dangerous combination. If you do end up trying this, I would suggest wearing this while turning:

If you can't afford the full suit, at least make sure you're wearing the cod piece! Family jewels and all that. :twisted:

On a more serious note, if you have 2-part jaws, i.e. able to screw/bolt accessories to the jaws, making steel extensions to bolt on wouldn't be that difficult, but it might require some milling. Ideally, you would want the jaws knurled to provide more grip.

Is it just me, or does the codpiece just draw all sorts of unwanted attention to that region? :ROFL:

I'm not the greatest historian and I may have my time periods wrong, but I believe that at one time "fashionable" men wore codpieces all the time with their regular clothes. And I believe the whole point was to "draw all sorts of unwanted attention to that region".
The opinions expressed above do not necessarily reflect those of the management or of the little green men who have been following me all day.

'Tis truth. It was always a source of amusement for me in history class.

Great, I just had a visual of Todd looking like Adam Sandler in You Don't Mess With The Zohan....

Brain brush, please. :huh:

Well, I made a couple, actually two couples, and you are
absolutely right about turning a pipe with it. My lathe is
relatively sturdy, it's a 14/11" older Rockwell, but without
a center holding the tail, the physics of this launchpad were
evident. (':(')

So I finished carving the two authors I was making by hand.

Maybe someone will link to a video of turning a bent shank on a
lathe.

If the shank is slightly bent, but not curved, the approach would be very similar to Tyler turning this bowl: http://www.tylerlanepipes.com/modules.p ... 0a%20Lathe

If the shank is very bent or curved, as in Tyler's hawkbill, you will have to freehand it by sanding.

Frank.

I may be able to satisfy this need. I've been meaning to make a better video of pipe carving, I just need to get a round tuit and I'll be good to go. Oh, and use music that isn't copyrighted.... :bangin:

I've been threatening to do this for a couple years, and make them available on DVD. Maybe that's a good winter project for me.

The tyler video was helpful. Just getting it
started with a nice circle would make the
rest easier. Also, he turns first and
then drills the chamber. That way the
briar is easily secured with the tailstock.

By the way, on the 6" crapsman chuck
I have if I use the diy jaws with the
other pair the standard steel ones,
and a dead center on the tail, there
are no problems. Still, I think I am
writing to Mrs Santa Claus for the
utility grip from PSI...

One thing I didn't admit earlier was that
I did have briar and part of wooden
jaw zoom into outer space. That's why
I made two and changed the design a
bit. Fortunately, I had a sense I was
living dangerously and was standing
back to the left of the headstock and
with a shield. Things tend to fly off
to the right... Ok, I am 55 and should
know better ... 8) :arrow: :oops:

On music ... my son does electronic
music -- from house to ambient, so
I'll ask him if he wants to donate some
and you can see if you like it.

Naw, but if I distribute it on DVD for a small donation, someone's liable to come after me with a DMCA lawsuit.
