I think you may have given us the answer. I also sand both ends of my blades. I read someplace about the oil and the need to rough up the blade ends so when they clamp up they will stay. I am new but this made sense so I do it.
It seems as if I didn't have bad luck I wouldn't have any luck at all. I think I need to take my DW788 back to Woodcraft. It's knocking more at high speed than other speeds. I have been running it on #7 which is fine but it seems like the knock is getting worse. I know I might be able to fix it by greasing the bearing but that might void the warranty and I don think I should have to do it on a saw I bought on 8/25/2016. From what I have been reading Dewalt put very little in these bearings and it was cheap grease. I know Dewalt has to make money and I want them to but this is not treating the customer fairly.
PS - Boy does this put me in a bad mood.
I just called Woodcraft and they have an EX 16. What do you guys think about getting that instead of another DW 788?
Well Denny I ordered from Ocooch Hardwoods for two reasons. One is I ordered some hard wood and the other is I don't have to get up off my fat **** and go get it. You might say I am lazy.
For those of you that use BB ply which do you use? There is the BB that Lowes and HD sell and then there is the good stuff that comes in 60" X 60" sheets. I can by the good stuff at a lumber company about 10 miles from me but you have to spend $200 for them to sell to you. Of coarse you can buy $200 worth of lumber and it will not cover the bottom of a pickup. I do buy just about all my lumber from them.
