Thanks, Jeff. That sounds like "The WISE Approach", but I'm going to push ahead on my own for a couple of reasons:
1) I'm kinda stupid.
2) I've given myself today as the deadline for having this saw functional.
3) SawmillCreek requires me to post under my real name, and while I have no concerns about SMC members, anyone can read these forums and then "stop by" to relieve me of my tools when I'm not at home. I'm reluctant to mention my location on any forum, but especially on a forum where my name can be combined with even my general location. A local guy had his entire commercial shop stolen by thieves who rolled up in a truck one night and left with nearly every bit of capital equipment. So I take security seriously.
Here's my rigging, so far. I think it'll work well because the cabinet+trunnion+motor is heavy, but not ridiculously heavy. 'Probably weighs 250 to 300 pounds, and the if all goes well, it'll be suspended for only a minute or two (fingers crossed, and unbroken so far). If this looks like Disaster Waiting to Happen, somebody tell me now...
