Your customer has requested you service his favorite family heirloom - a World War II Arisaka Type 2 Paratrooper rifle (also called aTERA - Teishin Rakkasan Assault/Raiding Paratrooper).
After you take note of the serial number, you notice the retaining pin used to secure the barrel/forearm assembly to the receiver appears to be missing the D-ring. The D-ring is intended to aid the shooter in pulling the wedge to disassemble the rifle for transportation. After bringing it to the customer's attention, he has requested you create the D-ring.
As this is a relatively rare firearm, finding reference materials can be very challenging. Use the discussion post to brainstorm answers to the following questions:
- If you can’t find a physical sample or blueprint of the part you are trying to create, how else can you get measurements for the part?
- How might you determine the material to construct the part from?
- How would you test the part for quality?
