I tried an M11x1.0 and couldn't get the refill in past the threads. I think it needs to be an M12x1.0

Thanks for the info... i sent a re-fill into tapco usa, they are going to measure it and make me a tap that fits... let me know if you want one, the price gets significantly cheaper the more i order.

Pictures
Don't have a picture, but do a search on google, sharpie has made a stainless pen that is goofy lookign becuase it has sharpie written all over it, but the ink is in a threaded refill that threads into the body, so i am going to make my own pen, but i need the thread count so i can tap a lower pen section.

If it is indeed a standard thread like a 12 x 1, you can buy all you want for less than $10 at http://www.victornet.com/ No need to get a special one made.

Pretty sure its not a standard thread. M11 is too small and M12 is too big. I put a caliper on it and the major diameter is about 11.2.

You guys might be right... rather than the endless trial and error, the Tapco people are supposed to call me tomorrow and let me know what it is.

Calling
I guess i could... i may have stupided out on that one, but i thought of it, and i figured that they wouldn't give me that information, so i didn't call them.

Sharpie
Mine is a 1/2 X 20
You may have to run the die on the refill as the threads are formed not cut but even after
I run the die on it there is not much material removed at all.

Forget . . .
Forget my "Bright" idea . . . I did and Sharpie says that is proprietary information and will not release it . . . .
It was a good try . . .
You were right . . . .they won't share . . .
I think your TAPCO idea was the best . . . please include me in a "tap" buy . . .

Where do you get the Sharpie refills? Are these something that Office Max/Depot carry? I'm curious to see what we're talking about here...

McMaster Carr carries a variety of taps, including NEF series and others.

Select the pull down tabs at the top to see the variety of sizes they have.
Here's some more good reading if you're bored:

I don't have a refill to measure, but if you measure the major diameter and the pitch with calipers, you should be able to see if there is a standard size that's close. Here's some more reading about measuring.....

Interesting. So it's an actual sharpie marker. Cool. Is the cap friction fit onto it?
Yes. While the stainless steel holder is cool (think "Back to the Future"), I would like to make my own holders for the refills. Time to learn how to make closed end pens.

Tap Size
When I measured the major diamter, it was around an M11.2, I don't have an extensive tap and die set, so rather doing the old purchase taps just to try gig, i sent it off, i hope to hear from them today.

OK - now I have a refill to measure.....
Major diameter = 0.451 - 0.454"
~ 11.45 -11.53mm ---> 11.5 mm ---> not standard, consider using 12mm
7/16 = 0.4375" ---> too small
15/32 = .46875" ---> not standard
1/2" = 0.5" --> loose fit
4 thread pitch ~ 0.154"; 1 thread pitch ~ 0.0385" ~ 1mm ~ 26 TPI
M12x1.0 has a major diameter of ~0.472", and is available at McMaster Carr for $30.
http://www.mcmaster.com/#26015a222/=4adoqu
I'm curious now to see how measurements differ from others - how loose of a tolerance are these? They do appear to be injection molded threads, not cut, so I expect pretty loose fitting.

From a drill/tap chart, the 1/2-20 requires a 29/64" (0.4531") pre-drilled hole to tap for a 75% thread, or 15/32" (0.4839") hole for 50% thread. Since the major diameter of the refill I have ranged from 0.451 - 0.454", a 1/2-20 with 0.4531 pre-drilled hole would be too large.

Picked up a refill today and did a little measuring. A 7/16 drill is just about perfect. Measured the threads with a thread guage and found them to be exactly one thread per millimeter. I used a mini metal lathe to make the threads.

Chuck, What are you going to do with the cap? Could you not use the stainless cap and then have a look similar to whatever pen kit it is that has an all metal cap?
Chuck Key
Member
Yes, would probably use the Sharpie cap. I noticed they have "China" stamped on the clip though.

Chuckie, i am right along with you, you need to drill a 7/16 hole to get the refilll through... what tap size did you use to get the threads in?

Just FYI.... I buy all my taps from Victor tap and die and they have this particular tap for $8. I've got a slew of their metric taps and so far have had no problem with any of them.

Enco sells a 12x1 tap for $6.95 for anyone that may need that size.
http://www.use-enco.com/CGI/INSRIT?PARTPG=INSRAR2&PMAKA=891-4977 Enco usually offers free shipping on orders of $25.00 or more.

I know they would be cheap but I wonder if HF would have such a tap?
John
John
Yes, they do. Several years ago, I bought a 40 pc. set of metric tap and dies from HF for $9.99. The M12.0 x 1.0 is one of the largest in the set. Although they're cheap, they work quite well and can last a long time if properly cared for.

Pen with Sharpie refill
Just a note of caution. Sharpie may have some protection on this pen design and certainly cares about their trademark. The pen you create is not a Sharpie pen, but could be called a pen with Sharpie(R) refill.
While the chances are slim, just trying to prevent the nasty letter from their attorney.

I agree with Tim, We have seen this happen in the past when people use the name Mont Blanc etc. It is Mont Blanc Style at best and even better avoid brand names at all.

Chuck, very nice job! Someone asked a question about the cap, why not use the same material as you did for the body of the sharpie? That's what I did on mine. No clip as I carry it in my computer bag.
