I am looking at the Rikon Slow speed grinders as part of my sharpening system w CBN wheels at the recomendation of a friend.
How superior is the 1HP model to the 1/2 HP ? Is it worth the extra money ? And why ?

Absolutely yes! It powers up remarkably fast, doesn’t falter on holding speed, and can handle the added weight of two large CBN wheels.
I have the 1HP Rikon + Mega Square combo and love it. It was an upgrade from the 1/2HP Rikon with two of the 4-in-1 wheels.
I never even considered the 1/2 hp model. Part of that is because, after 30 years of concrete construction, I prefer things over built rather than under built. I have 2 of the 1 hp Rikon grinders to go with 2 Baldor grinders. The Rikon can keep up with the Baldor grinders power wise, and are 1/4 the price. They do not run as smooth as the Baldor grinders, but for the price, it is a great grinder. Both will handle the solid steel wheels from D Way, and those are what I have the most of.

I have one of each. They both work ok for sharpening lathe tools with the AlOx or aluminum CBN wheels but it's a little wimpy. The heavier steel CBN wheels have been a problem for some with the 1/2hp grinder - some reported having to give the wheel a push with the hand to get the grinder going.Quote:

That didn't matter much to me since I use the Wolverine rests.
I also have a no-name 3/4hp and it's good too.

When CBN wheels became kind of affordable, some folks put 2 on the 1/2hp. For some, they said it felt like they should give it a spin by hand before hitting the switch because it started so slowly.
What John Keeton said. Would not even consider the 1/2HP after using the 1HP. I started with the 1/2.
I have the half horse with one cbn wheel and one normal wheel. It works just fine. If I planned to install 2 cbn, I think I'd go with the 1 hp just to have some margin.

I'd get the 1hp. We bought one for our club and it's at full speed in a second. I was at a friend's house the other day and went to sharpen a gouge on his 1/2 HP Rikon with one CBN and one stone wheel. I wondered why it was only running at half speed while I sharpened, that's when my friend said you have to wait for it to build up speed. So I stopped and waited what seemed like 5-10 seconds for it to build up speed. I'm not used to that, and if that were mine it would drive me nuts. I would probably put off sharpening until it's absolutely necessary (which is bad) just because of having to wait on the grinder. Get the 1hp and you'll never have regrets.
