About a week ago I was using my 15 year old inexpensive Ryobi mitre saw and the blade was spinning for up to a minute after the cut. Clearly a problem with the electronic brake. After explaining to SWMBO that this was very dangerous and the limitations of a saw that couldn't handle compound mitres, I ordered a Delta 36-255LR 12" TwinLaser miter from Amazon. Cost was $235 out the door
Last night I decided I'd try to take apart the old Ryobi to see what was broken. A Google search before starting the disassembly yielded a sentence that said something like "three of the last electronic brake problems I saw turned out to be loose arbor bolts". I laughed at the stupid mistake others must have made and walked out to the garage. Five minutes later my old mitre saw, with its tightened arbor bolt, was working perfectly.
No update planned to SWMBO. Anxiously waiting arrival of new, and ummm ..., less dangerous saw.
