This grinder is accident waiting to happed
I dig the color selections.
Yes, a wheel guard is in order. Then I'd feel safe in trusting the discs though, being made for ~10,000 rpm. Can't figure how to get them round, they'll eat a conventional dresser.Quote:

Actually with the exception of not having a guard it is probably safer than 99% of the conventional bench grinders or at least the wheels.
that motor may turn at a max of 1/3 the rated RPM of those wheels when they are new and full diameter. Sandwiched together as they are would make it impossible to damage 1.
As far as dressing them and truing the OD they will eventually true them selves if the operator continuously moves his work piece back and forth. focusing on the high spots. it won't ever be as smooth as a finely dressed grinding wheel but near enough. I used to stack as many as 10 new 1/4" thick 4" wheels on my old B&D straight grinder for finishing out the bores of pin locations on cat equipment I usually glued them together to maintain the stack up when not in use though.
TM51 is right about eating a conventional dresser though. I tried to use my 7 spur wheel Ridged dresser on my wheel stack once make that twice first and last at the same time. it ate the rawls sown to a nub in no time.
Holy Moly

This motor has 1.350 rpm.
Hey, you use what you have access to.
VERY clever. This build hits on a lot of the factors we like:
-washing machine motor
-reuse of commonly discarded material
-conglomeration (forming a grinding wheel from many cutting discs)
My best guess is that compressing the discs like that would indeed reduce the risk of them exploding, as they love to do when run individually.
Conceptually, this build reminds me of pauladan's hedge trimmer.
Yes, together these cutting discs are pretty safe.
Impressive indeed Mr. Liberal. What is the device on the back? A cap?

I'm happy to know I'm not the only person who does that! I use mine on an old 1959 sears table saw. I never have enough used ones to make something wide like that.
