Beautiful job Bob!
I just bought one of those Multi-master type tools last night. I saved >$500 comparison shopping and buying $4000 worth of materials for my roof and thought I deserved a treat when I saw a pile of the Dremel version for only $99. The Dremel, surprisingly, got somewhat mixed reviews so I can't decide whether or not to return it and get the Rockwell later. I obviously worked like a charm for your deck job. Other tasks I had in mind for mine were cutting an opening for a window in drywall and removing grout, tile, mastic and thinset. I was also hoping to use it to remove fascia on my house, but reviewers kind of indicate the Dremel doesn't have the omph.
I was wondering if you'd mind if I posted your project to the site for all to benefit? In my non-existant free time I am planning on trying to bring this site back up to snuff for Phil. Unfortunately things will start getting in the way shortly (boat isn't in the water yet, roofing job and a work trip).
Bob
