If all is good, disassemble and paint the wood to protect it.
Grind / bevel the flanges, deburring the metal using the Dremel grinding bit.
Reassemble - DONE!
- The cane I used was height adjustable, two pieces telescoping for adjustment. I'd keep this feature next time. As I mentioned in the design goals, waist-high is a good height. However, my waist is not the same height as others. By fixing the length to me, the plunger is a bit too long for most.
