Construction

Parts needed

• 1 HGG (barrel, grip, and ink tube)
• 1 RSVP (cap, backcap, and grip)
• 1 Uni-ball Signo DX tip
• 1 SGM, Anyball, or Profile grip
• An insert (approximately 8.5 × 2.5 cm)
• PTFE tape

Text tutorial

1. Remove the RSVP grip and place it inside the RSVP cap. Remove the HGG tip, grip, and ink tube for the initial fitting; keep these parts for later assembly. Remove the Signo DX tip. Cut three front cells from the Profile/Anyball grip.
2. Saw off the screw-thread section from the front of the HGG barrel as shown in the tutorial, then sand the cut end. Check repeatedly that the Signo DX tip fits; PTFE tape is optional if the fit is loose.

   

   

3. Remove the HGG barrel backplug and insert the paper insert. Add PTFE tape to the RSVP back screw section, fit the RSVP backcap with its grip inside, and tighten the joint so it does not move.

   

4. Place the cut grip, HGG grip, ink tube, and Signo tip inside the HGG barrel in the orientation shown below.
