I just finished using the Turbo Plane. Bought a post & beam house but all the beautiful posts & beams had four coats of paint on them (ugh!). Bought the TurboPlane specifically for this job. It did the job very nicely but there is a learning process. Mind you I was planing beams above my head, and I was often on a ladder so in a controlled environment it may be better. Initially it was hard to control. Eventually I found that I was able to use the chip deflector on the grinder as a fulcrum/depth guide. That helped a lot. Once I got the hang of it it was actually fun. Really throws shavings, chips and dust.
One feature I like a lot is that the cutting edge does not go up the perimeter of the disk. Only the face of the disk cuts. This may not be good if you're doing wood carving, but when planing a beam that abutts plaster, you can ride the disk along the wall without damaging it.
I surprised a few nails with it, inspecting the blades each time. Not a visible nick in them. If the blades went dull, I sure didn't notice it. If you haven't already, check out the YouTubes showing it in action.
Ditto others on the importance of safety: glasses or face shield, mask or respirator and hearing protection.
Hope this helps, Gary
