Product Description
A tool for safe and accurate alignment when fine-tuning the hole diameter of T-90º connectors.
Requires:
1. two "registration sticks" sanded to easily insert/retract from the tool
2. at least two 1.5mm x 10mm stainless steel dowel pins. (four best)
One source: uxcell 1.5mm x 10mm Stainless Steel Dowel Pin
3. resizing the registration pin holes using a 1.5mm drill bit.
One source: Mtsooning 1.5mm Micro Twist Drill Bit
Since the guide hole for drilling a side-to-side through-hole is 3mm, the tool does not serve as well for drilling 2mm.
To solve this problem, use the pointed end of 3mm bamboo for a "registration stick".
