I bought a Rikon grinder last year at Woodcraft. I think $89.
Well the stones suck. Way out of round, wobble.
The center is not standard 1" ,it's only 7/8 and filled with something
rather than using spacers. Using the T bar diamond has not properly
I picked up a diamond point from Enco.
This too did not work, until I made a holder, which limits the travel.
Now, this thing is smooth and true. While it still wobbles, and will
cause me to buy new stones soon, I can say that the stones are cutting
nicely. I might go to the CBN wheels once course and one fine. Since
those really run true.
The shafts are perfect. I have a 1/10,000 indicator. and they are true.
Otherwise the grinder would have been returned.
They sent me one new wheel last year, but that was crap too. So it's a
low end POC.
The grinder is nothing special. The rests are useless as they attach to
light gauge steel. I have my own rests and might be getting the
Oneways for my gouges. Or making a better set.
I might go to the CBN wheels once course and one fine. Since
The best price on cbn wheels is at woodturnerswonders.com a pair of 8x
1.5 wheels is $250. Other places want around $200 each. Another
advantage to cbn wheels, is that you can remove the guards on your
grinder, since steel wheels don't explode. Thus using 1.5" wide wheels
instead of 1" wide wheels, The only disadvantage, is that you can't
grind any non hardened steel. No bolts, no angle iron, etc.
Under CBN Wheel 8-inch, 80 grit, 5/8" arbor on the web page it says As
long as the wheels are properly used as intended this should not cause a
problem as they are machined from one solid piece of steel. which is
what I have, but at least some of the others do say they are 6061
True, their main use is for sharpening High Speed Steel, and powdered
metal turning tools. They cut faster and cooler, than stone wheels. And
since they never need truing, you can mark the wolverine, or other jigs
for different tools and be able to reset to those markings for repeated
sharpening. When you true stone wheels a couple of times, it decreases
the diameter of the wheel forcing you to change the setting of your jig,
so that you don't change the grind angle on your tools.
