Parts:
- the drive gear, 50T gear and shaft from the IDGA set · already on the bench
- caliper · tool
- medium-strength threadlocker · consumable
Do:
- Read SB p.21–24 first.
- Slide the drive gear on, set screw on the shaft's machined notch, to the 15.6 mm p.21 dimension.
- Apply threadlocker and tighten the set screw carefully; its head strips easily.
Check
Caliper reads 15.6 mm at the dimensioned face, and the set screw is on the notch, not the round. Step 08.18 corrects it.
What you're looking at
The filament drive gear is the toothed wheel that pushes the filament; 15.6 mm is where its teeth line up with the filament path. Its set screw must land on the flat machined into the shaft, not the round, or it creeps.
