Jr Gent II centerband removal

workinforwood · Jul 31, 2008

No doubt this probably has been discussed before, but I likely missed it. I do not have a tap and die. I would like to remove the centerband on the JR gent kit so that the cap blank can be built to be the extra 1/4 inch longer or whatever it is the band is and the kit can just be pushed all the way in so I can use the threads but the band would be my own. Seems to me that I've been here long enough to know that anything is possible! So has anyone done it and if so, how?

Jeff, I went out to the shop to take these so I could SHOW you instead of trying to explain it.

This is a piece of maple with some 3/16" plex glued on top. The trick is to drill a hole just a hair smaller than the first ring on the CB and then file it until it fits snug and won't let the little gold ring through.

Here's a shot of the CB in the hole. The gold ring is resting on the plex. I tried just using wood but it's too soft and the gold ring kept getting stuck.

I use a piece of oak for protection against the hammer.

Rings off and CB is punched through.

Finished! Took all of 30 seconds, hope this helps.:wink:

yep, can't get much better instructions than that..thanks Rick!

one more question not shown is that I see you removed the plastic..did that just pull out and can be put back in?

rherrell · Jul 31, 2008

Yep! As a matter of fact you can put all the rings back on too if you change your mind.:wink:

Jeff, thanks for asking the question and Rick, thanks for the great (and clear - even to me!) answer. That answers my unasked question, too.

workinforwood · Jul 31, 2008

And...what about that remaining piece of centerband that won't punch out, how can I get rid of that so that I have no showing metal at all? That's my ultimate goal. I don't know how hard the metal is, if I can spin it between centers and knock off that last part with my skew or parting tool.

jskeen · Jul 31, 2008

I would guess that even if the metal for that last visible ring is too hard to remove with a turning tool, you could do it with a file.

Just as a FYI
Once you get those rings separated, it's fairly easy to turn a centerband from your leftover blank and reassemble it.

rherrell · Jul 31, 2008

Jeff, I haven't tried turning a JG CB but all the other ones I've done have been brass. If that's the case then you can do as James suggests and use a file or what I do is use an old 1/2" skew that I use just for brass.

Thanks Rick was wondering the same thing as Jeff.

Rick,
Thank you for the show and tell.
I'm a visual learner and very much appreciated the extra time it took to add the pictures.
I could not be any more clear to me.
Thanks again.

That last ring can't be knocked off - you are looking at 1 piece of metal and 1 piece of plastic (the threads). You CAN remove the plastic from the metal, but then the threads are not supported near the front.

If you do want to do that: Use the same sort of block described above, catching the front ring this time. Unscrew the nib from a FP section. Screw the section into the CB threads and back out a little. *GENTLY* tap the section to drive the threads back. Once you get going just push by hand. Then you have to fill that gap (the step in the plastic threads) with something - might consider epoxy.

If you have a collet chuck: The better way is to grab the metal in a collet and use your parting tool to turn down the ridge. It's soft metal and you can turn it easily with a sharp parting tool. Once you get down to the same diameter of the rear extension you can push the whole thing in all the way.

If you don't have a collet chuck... get one ;-) You'll not regret it. The PSI one is not terribly expensive and actually quite nice - too bad they package collets with it. Too far apart to be useful...

OK, I can see the pictures now, but how do you get the black rubber thing off?

Interestingly the pictures in Rick's post no longer show for me now.

rherrell · Aug 5, 2008

The black center band coupler isn't in there very tight, just pull and it'll come out.
I have no idea what's wrong with the photos, they work for me.

Ligget · Aug 6, 2008

I am a visual learner also, thanks for taking the time to photograph and explain what you do, very easy to follow!

workinforwood · Aug 7, 2008

I really appreciate all this information. I have it all well stored to memory, you guys are the best!

bananajeep · Aug 12, 2008

Thanks for the visual. I was able to follow your description, but pictures are worth a thousand words. Have you ever tried to get the centerband off of the Jr Retros. I had to gently pry with a pocket knife and still had tiny marks on the center metal band. If you can come up with a solution let me know.

Thanks

Mike

I think the center of the finial on the cap is just pressed in. If your hole
is just larger than the black, silver or gold insert in the finial, you can knock
it out with a center punch.

OR

if you're too aggressive when disassembling the pen, it will come out whether
you want it to or not.
.. or so I've heard. :redface:

I don't actually understand your question. Do we realize that this post is more than a year old ??!!! LOL.

RAdams · Dec 20, 2009

yeah that is kinda my fault. I wanted these pics to be findable, so i upped the thread. I will be building the jig soon and wanted to use the pics for ref. lol.

Since this long dead thread is once again alive... Since I've read it I want to try it but I have one question: do you have to do anything to modify the upper tube to work once you shorten the thread adapter? Or does it just work with no changes?

GK

workinforwood · Dec 23, 2009

You do not barrel trim the CB side of the pen all the way to the tube. Lets just say the with the ring removed, it makes the centerband 1/8" shorter just to make the math easy. So the barrel should be an 1/8" longer. So you trim it, but leave it an 8th longer and the fact that there is no tube for such a short distance will not matter. The CB will still press in just fine and you'll still have plenty of strength. You can also split the difference, so you are 1/16th longer on each end past the tube.

Actually you can trim the CB side all the way to the tube with no problem. I have shaved many a CB and always trimmed all the way up to the tube.
