Well I himmed and hawed, I planned and I procrastinated, but I finally did it.
My wife has always complained that she is the only one that has not received a fountain pen from me. I didn't want to tell her that my intention was for her to get my first full custom for her birthday on the 17th. The whole thing took me about 14 hours over the last 2 days. Silly me, I had told her that I was all finished my custom orders for Christmas. A lot of fast talking to explain all the shop time on the weekend.
I chose a piece of Charoite TruStone for my first attempt. She loves purple, and didn't want acrylic. {I'm a glutten for punishment}. I had a number of problems.
Four attempts at a section to fit a bock feed.
The first fail was in the TruStone, the section to body thread broke while trying to thread it with M9x.75
The second was not quite a fail. I did it in black delerin so I could work on the technique without trashing trustone. It turned like a dream and threaded easily. This time I cut the body threads first then drilled for the convector. Worked great. First mistake, was that I made the section to long. The schmidt converter would not reach down to the feed. I had to open the hole quite a bit and then ended up with 10mm of convector pushed into the section. The second mistake was using the delerin. I polished that stuff forever, and could not get the scratches out. I haven't tossed it, one day I'll come back and polish it up for something.
The third attempt was a fail again with the Trustone. It broke in the same place as the first attempt. I almost had the converter hole drilled out, when it broke. I guess my problem is with the material, not the technique.
Forth and final attempt/success. I did it in a black acrylic rod that I have. Not sure of the exact type. Every thing worked wonderfully. All threading went well and section was ready for a body.
I used "The Penturners Bible" for guidance. Since I didn't have the same tooling, I had to alter the dimensions to fit what I have. I photo copied the dimension page, whited out the numbers and used it to record my own measurements. Helped to visualize.
Section to Body M9x.75
Cap thread M12x.75
I used 3in1 oil for cutting the threads.
I used a square carbide cutter to work the trustone. With the lathe turned down very slow, I think maybe 200-300rpm, it worked great to get accurate cuts for the threading.
Thanks to my handy dandy Princess auto super set of drill bits, I was able to figure out the best ones for all the steps I did. You can see the measurements I used in the photo.
I did the body first, then the cap. The problem with that is that I didn't have the cap to test post. I had to reshape the body after I did the cap so that it would post. I had made mandrels to hold the cap and body to shape, so it was just a matter of rechucking it up.
I finally added a rollstop from a charm of the Tree of Life. Shaped on a dowel and thinned, then epoxied onto the cap.
Overall stats for the pen.
147 mm Capped - 24 gr
141 mm Uncapped - 14 gr
160 mm Posted
13 mm diameter for the body at its widest
15 mm diameter for the cap at its widest
Excuse the pictures. That's something I still need to work on.
All comments and critiques a gladly welcomed.
