Okay, I'm going to do the best I can to describe my problem, and see
if anyone can deal with it reasonably.
I have my granfather's scroll saw. I would say that my emotional
attachment to this item is slight. If it were COMPLETELY non-working I
would throw it out. It is a really cheapo "Durabuilt" saw made in the
mid 80's overseas. No variable speed, just goes full bore.
However, the motor and everything work just fine, with one MAJOR
exception. The cam holding the blade wobbles like mad, and is
dangerous, not to mention that it's nearly impossible to make a cut.
It would appear that the bolt that serves as the, for lack of a better
term, "axle" for the cam is a bit worn, and so is the hole in the cam.
There is excessive play there, and the part of the bolt that should
have a nut on it has stripped completely. I can throw on a few washers
and make the bolt nice and solid, but there is still a fair amount of
play, I would say a 16th of an inch at the end where the blade is.
There is no easy way to fix this, unless I throw a shim on the side of
the cam, which seems risky.
So, is this fixable for less than the cost of a new cheapo saw, or
should I just toss it and get something else?
If I can give more details, let me know. I would like to fix this
cheaply, but I suspect it's going to take a fair amount of
machine-shop work, and I doubt it would come cheaply.
