has anybody used one of these on siding? I wonder if they get right up to the next lap and how large of a piece can it do at once? How long do the blades last?

There is no good way to strip a house that I know of. I used this system years ago to strip clapboards on an old NE house that had to have lead paint on it. Was slow and the biggest problem was the nail heads ground off with the paint. Also it was hard to get the lower edge of the siding without scarring the verticle face. The discs lasted ok but a 36 grit disc that it takes to be aggresive enough to get rid of the paint leaves a pretty rough surface overall.
Have never done it this way but have heard of using a h2o/sandblaster system that is supposed to work pretty well and though messy is not harmful.
Not sure what is current in this category but I sure would never strip a house again with the grinders! Usually the reason to strip is because the paint peels badly which is a result of excessive moisture in the sidewall cavity behind the siding and will keep on happening and happening etc. anyway. Good Luck!
*RJT, uses for this tool are myriad, and the tool employs a pair of rails, for depth adjustment.The discs last a long time, and can be loaded with melted paint. Brush cleaner will revitalize the disc. Slow your rate of grind, and the melting will be less. Discs are available in 24, 36 and 42 grit, and it's a worthy tool IF you are working a cracked, pillowed mess of a job. Follow-up sanding is needed, for corners, and up under the clapboards.
*There was an earlier thread on this and the Metabo paint planer and the one that's an adapted 4.5" angle grinder from somebody in RI. Maybe the webmater knows if it's in the archives or got lost in the crash.Anyway, I posted there about a 3M product that's like an expanded plastic matrix about 5/8" thick, 5" or 6" diameter H&L backed for use with ROS. Never got to try it because I'd have had to buy a $100 box to get one to fit my 6" ROS. Theory seems to be the open matrix is air cooled so the paint that's still sound doesn't start to melt off the substrate the way it does with regular sanders. (You can never get a feathered edge to sound stuff).Anybody tried these?
*I probably won't go for the PC stripper because none of the siding has a flat surface, warped this way and that. 100yrs old y'know.
*RJT, it won't mind, it'll grind it flat for you. Now that can be either good or bad, only you know for sure.
