Pen Pin chucks
- Thread starter Jim
- Start date
Pin chucks round bare hard wood like box or metal of the required diameter with a bit on the round milled flat lay a pin on the flat slid it in the hole and turn this will make the pin roll to one side and clamp against the inside of the hole we used to use them to make salt and pepper mills
Skiprat has a walkthrough on making an O ring pin chuck. I prefer pins rather than the o ring.

I bought mine from America at $14 and then paid £4 customs and £8 to the post office for paying the £4. But we won't go there again. Pencrafts UK have another system 'The Grabber'. I bought one but didn't get on too well with it The "Grabber" Closed End Mandrel System for #2MT headstock

Carl Jacobson has a video on pin chucks for duck calls.
I made one with a 6.9mm bar of silver steel,milled a flat on it and use a nail with no head as a pin.

Made a couple of those from old rod and nails cut for the pins!
As per Paul's quote Jim, the ones from CSUSA are $14.95 (£10ish) and the grabber is a penn state design and imported from USA.
I have tried most things and ended up turning between centres for my closed end pens.

Forgot about this Jim.
Don Ward did a tutorial for closed and pen .
Take a look.

Might find it useful.

Yep agreed, my jam chuck method is the same thing really.
All I am doing is taking the taper of the centre out of the eqation and giving me something to push against without enlarging the tube to split the blank
Just looked at that tut Eamonn and there is a similar thing to what I make for closed ends.
I referred to it above as my method.
Obviously it's not my method unless I did it first but here is an excerpt from the tut giving due credit, although I had never heard of these people until now nor had I seen that tut.
Just goes to show when you think you may have invented something init?
That's why patent searches have to be carried out before filing one not that I would have for something simple like this.
But then I wasn't trying to reinvent the wheel just find a means to an end init?
I don't do all the long winded prep for either. I make it fit the chuck that is nearest to hand, take it down to just below the tube diameter and gently force the tube on over a thin rubber o-ring which hold it firmly on the jam.
WOODEN JAM CHUCK
I noticed a post on IAP by Gerry Rhoades and how he uses a wooden
homemade jam chuck for turning closed end pens. Gerry explained that the idea
was shared with him by Mike Vickery. See Figure 5. Here is what Gerry had to
say about making and using these wooden jam chucks:
“The idea is not mine. I got it from Mike Vickery. We were corresponding about
pin chucks and he told me that he sometimes did this (made his own from wood)
if he didn't want to wait for a pin chuck to be made or shipped. I use a Beall collet
chuck with a ¾” collet. I've been using a ¾” poplar dowel. I cut a piece of dowel
about 6" long and put it in the collet chuck. I then turn it down until it's close to
the inside diameter of the tube. I finish taking it the correct dimension with
sandpaper. When the tube will just barely fit, I give it two coats of thin CA and
then sand it back down. I also turn a shoulder on it that's about 0.020" larger than the bushing diameter and coat that also with CA. I then force the blank onto it
until it meets the shoulder. I use the tailstock just like I would if I was using a
dedicated closed end mandrel.” -Thanks Gerry and Mike

I have never found mine unreliable they do exactly what they are supposed to do, but I can see that made from wood they would be a lot less faff to make. My neighbour just gave me a complete dead box so I will use a piece of that to try one.
Peter
Yup - as Woody says. Never found them unreliable, but to each his own. As stated by a couple of others it can be easier and produce better results to turn between centres.

I have never used one so I can't comment on their reliability. I do what Brian does and make a hardwood jam chuck. I use the tailstock for support right up to parting off so effectively turning between centres.
I think that's the important part which has not been mentioned till now "use the tailstock for support right up to parting off".
That's when things become unreliable when removing the tailstock and gaining a confidence in the pin or maybe being over confident and knocking it off bonk or splitting the blank.
All of which I have done and do speak from experience.
