In case you might not remember, I discussed buying used woodworking tools at garage sales.
Well, this is one of those things that I would have rather not purchased.
I bought a Delta model 23-710 Sharpening station. The machine is a grinder with two different stones. One was vertical, and the other was horizontal. The horizontal has a mechanism to operate with water. It included a water reservoir and funnel to keep the horizontal stone wet. The reservoir/funnel part was missing. I also did not have any tool holder jigs to keep the tool straight. I even planned how to make my own tool holder. I even made my own spanner wrench to remove the horizontal wheel.
It’s been a while, so I don’t recall what I paid. I think around $20, but I’m no longer sure. If you don’t remember, then it must be a bargain, huh?
I thought this thing must be really cool. And then, after I got it home I began my research. After all, how does this contraption work anyhow? What I learned was that people did not like it at all. The machine shook furiously when I operated it. It seemed that the horizontal wheel was not balanced. On closer inspection, the wheel was not centered on its axis.
Anyhow, after only a bit of research, I determined that customers were routinely not happy with this machine. The largest problem seemed to be that the horizontal wheel was not true.
The vertical wheel seemed to work fine, but that was only half of the machine. Once I had removed the horizontal wheel, I could see that either the wheel was not round, or the spindle was not centered on the spline. I determined the latter.
One option was to purchase a new wheel, but how could I be sure that the new one would be any better than its predecessors.
My choice buy anew wheel, pass it off onto someone that doesn’t know the problem, or pass it on to someone that knows the problem, but has a better solution, or is willing to chance finding a good horizontal grinding stone. I don’t want to deal with the problem.
Motors hardly ever wear out, Any suggestions are welcome.
