I haven't made a closed end pen yet, but hopefully soon... Can one just get a regular kit, like a Baron Rollerball, and make it closed end? Would the cap post?
Mike; The short answer is YES. The Baron is my favorite pen to convert to closed end. I have even made double closed end Baron kits. When drilling the blanks, make sure to measure accurately and drill to precise depth(s). Remember the rollerball has a spring in the lower barrel, and you must drill the hole to match. Also the upper barrel needs a clearance hole for the ink fill point or fountain pen nib.
Hmmm. Looks like I don't have any pics of any of the closed end pens.:frown:
These are the drilling dimensions I used for my blanks. No guarantees, but these depths should get you in the ball park.
Dimensions:
Cap: Tube Length = 1.810"
Tube Drill Size = 11.5mm (0.452") Depth = 1.814"
Center Drill Size = 25/64" (0.390") Depth = 2.034" 0.220"
Nib: Tube Length = 2.089"
Tube Drill Size = 9.5mm (0.374") Depth = 2.097"
Center Drill Size = 1/4" (0.250") Depth = 2.851" 0.750"
