I've had DeWalt's 745 portable saw for over 8 years now, and overall it's fairly solid. I did need to get the arbor replaced several years ago as it was getting wobbly (quite scary when cutting, actually), but that's the only repair I've had to do. You do have to set the fence for parallel to the blade (some details on how the fence works below), and sometimes I've had to check the bevel on the blade to make sure it was at a true 90 degree angle as well (seems to slowly go out of square over long periods of time (like months or years), but it does cut accurately when it's been set into a desired angle. It cuts tenons VERY accurately, and it's to the point where you could use it for fine joinery in at least that regard. The fence also lifts off the saw if you need it out of the way, but it locks on to these two gadgets (sorry, don't know the name of them) which stay in place when the fence is taken off, so it can easily be returned to the exact place it was before. And having those two things makes it fairly easy to set the fence parallel to the blade. AFAIK it's never gone out of parallel since I set it a LONG time ago.
I only have a few complaints: For one, as at least one has mentioned here, the saw is quite loud like pretty much any jobsite saw. By extension of its design, there is a lot of plastic and not a lot of (or any) cast iron (like you'd find on a cabinet table saw). This leads to a lot more vibration than you'd get on a high end saw, which can be somewhat nerve-wracking when using it. Also, the arbor that's on there is not very long, so if you plan to do anything with dadoes wider than just the two outside blades stacked, you might want to look elsewhere (or just take several passes like I do
). Not sure what the other good jobsite saws (Bosch, Ridgid, and SawStop are the first three besides the DeWalts that I've heard/read the best things about) have to offer in terms of arbor length, but the capacity for stacking dado blades is quite lacking on the 745.
As a final mention, I will say that, with seemingly recently increasing frequency, I've experienced a lot of fuse-blowing with this saw, including when I'm plugged directly into what I'm pretty sure is a 220V outlet. I don't think my blades are dull, as they don't leave any burn marks unless I pretty much stop in the middle of a cut. In fact, my stacked dado is pretty much new, and even with just the two outside blades stacked and taking a somewhat shallow cut, I still blew the fuse. My main blade is a combo rather than a dedicated ripper, but again, it doesn't leave any burning unless I go REALLY slow, so it can't be that dull. Cutting through 2" thick red oak was enough to blow the fuse with this blade. Again, it's a fairly recent phenomenon unless I'm forgetting other instances in the more distant past, so maybe the motor is starting to wear out and overheat more easily. Hope it's not wearing out, as I'm not in the market for a new saw, and the next time I get one, I'd like it to be something like a Powermatic 2000 so I hopefully never have to buy a whole new saw again.
Also, to the poster above me, who was the prior owner of SawStop? Is that Steve Gass, the guy who demoed the cabinet model by sticking his finger in the blade in the well-known video or is it a different guy? What issues to people have with whoever it was?
