Hello all, a quick question for circle/swing blade folks.
How do you know when your tips have had their last sharpen? I have heard there is a width over the thickness of the side plate, but have yet to nail it down.
Cheers!
I don't have any exact number, but I find that as the tips get worn down they become more prone to chipping / breaking. When that happens it's time to swap out the blade and get it re-tipped. You often don't even notice a tooth missing until you go to sharpen.
About half of ours get damage, the rest slowly change sound, require more effort and we've run a couple till they start rubbing the plate and getting hot and flutter, well overdue.
I've run tips down to where they were 1/8" or so thick w/o any problems. Usually they start chipping first.
yeah soon as your cuts aren't intersecting right, or they're just looking thin.
Mind I run oversize teeth where I had to recut the pockets due metal fatigue so... different alloy, mine are a bit softer than the factory spec so less brittle and don't chip out ... individual mileage may vary.
