Hi Ron,
I have almost finished sculpting a chair using a holey galahad wheel attached to an angle grinder. I did a lot of research before I got the galahad wheels, and what got me over the line over the kutzall was that the galahad wheels has tiny holes in the discs and it makes it easier to see reference lines etc where you’re sculpting.
The galahad wheels are very easy to control, and from my research the kutzall wheels are the same. Have a look at Canadian Woodwork’s on YouTube, Paul Lamenski (I think that’s how you spell it), uses the kutzall wheels to sculpt his chairs. He highly recommends them.
However, one issue I had was that it kicked up dust everywhere! If you’re working outside it’s not really a problem but I was inside my workshop. I ended up buying the RAS 115 with 24 grit paper. WOW! The RAS is impressive, very easy to control and picks up around 75% of the dust. I then used my RO150 to smooth and sand the surfaces.
