I understand everything he did here, but my question is how in the heck did he turn the hobby saw blade with his drill?
Did he have a flexible extension that was really long? Also, the hobby saw blade would have to be a smaller diameter than the pipe, when the hone expanded how did he get the blade to engage the pipe?
I'm just curious, I'd love to see this setup. Seems almost like something he could patent and sell! I did a quick google search and its amazing how many other people have the exact same problem.
from what he said he used small diameter PVC pipe and epoxied the hone to one end of it and a bit for the drill to the other.Tennis balls kept it from wobbling ..also he somehow replaced all 3 stones on the hone with the little blades somehow.
