Steps

Step 1

Make the inserts
9.6 cm × 2.5 cm: one sheet
3 cm × 2.7 cm: one sheet
Note: part of the 9.6 cm insert won’t be visible once the mod is finished

Step 2

Take the Signo DX apart

Step 3

Cut off the top of the backplug, keeping only the tube part
Cut the front of the barrel as shown
Note: the Signo DX barrel is fragile, so use a tool that doesn’t squeeze it, such as a fret saw

Step 4

Sand the Signo DX barrel until it just holds the G2 barrel and the insert (see step 4, photo 2)
Note: cut the G2 barrel to 3 cm

Step 5

Put in the insert and assemble

Step 6

Clean out the Signo DX and G2 refills

Step 7

Sand the cut front of the Signo DX and the front of the G2 thread

Step 8

Measure 2.5 cm from the thread and cut

Step 9

Cut 1.7–1.75 cm of the clear Signo refill tube
Cut 2.4 cm of the clear G2 refill tube
Prepare them as shown
Note: cut the tube from the end opposite the original ink outlet

Step 10

Wrap some tape around the Signo front parts and assemble as shown
Once assembled, add the G2 refill front parts at the end

Step 11

Wrap some tape around the G2 refill parts and put the G2 body on

Step 12

Put the Signo backplug over the G2 part
Note: this part goes back into the Signo body (see step 13) and must face the same way as when you took it apart

Step 13

Insert the part from step 12 into the Signo barrel

Step 14

Prepare the materials as shown

Step 15

Take the Frixion cap apart

Step 16

Sand down the bumps on the Frixion cap

Step 17

Measure 2.55 cm from where it joined the body and cut
Cut the tip end as shown

Step 18

Remove the bumps from the Frixion cap and push it onto the G2 barrel

Step 19

Cut at the opening of the Frixion cap and put in the G2 refill end

Step 20

Prepare the G2 clicker as shown

Step 21

Place the G2 clicker from the previous step as shown

Step 22

From left to right:
assemble G2 metal refill < part from inside the Frixion cap < Frixion tip < Signo metal refill
Note: the part from inside the Frixion cap needs a hole made with an awl to fit; if it’s loose, fix it with superglue

Step 23

Cut the G2 spring in half

Step 24

Put one half of the spring onto the Frixion rubber part (see the blue Frixion rubber)
Then twist the other half together with the one you just placed (see the pink Frixion rubber)

Step 25

Assemble as shown
Note: see photo 2 for the grip length

Step 26

Assemble and put on the front grip
Mix and match as you like
