Okay, so today I was out messing around with my Hawk 220VS.. I had a order come in last night and this morning.. figured since I had just went through the saw and installed a new front tension cam and upper blade holder.. I'd play a little and do some experimenting.. I been thinking about the blade motion between the Hawk and the DeWalt.. and wondered if one.. I was burning through blades faster because the sawdust may not be able to clear out of the blade as good as it does on the aggressive cutting 788.. I started messing around with SPM speed while cutting on some 3/4" cherry... My 788 typically stays about 3/4 + on the speed dial.. The 788 runs 1750SPM.. My old 220VS tops out at 1500SPM.. so I normally ran it full speed.. I always felt that with the 788 the blade just eats the wood like a starved pig, LOL but when I cut on my Hawks.. it's more like just nibbling like a stuffed hamster, LOL
I started messing around with the SPM while cutting just playing with the dial.. the Hawk slowed down to just over the half way mark on the dial and all of a sudden the thing acted as if it was a very hungry pig.. now I'm thinking maybe the Hawk actually might be able to cut nearly as fast as the 788.. thinking maybe the faster blade speed coupled with a less aggressive saw may be running the saw too fast for the blade to efficiently clear out the sawdust.. and also creating more heat.. thus the blade dulls much faster..
Years ago when i first started with the 788 I always felt the saw was too aggressive and the very aggressive cutting would rock the board back and forth unless you was really holding it down.. and turns was a PIA.. until one day I figured out the the faster the saw blade runs the less it wants to bounce my board back and forth.. thus.. I run this saw at the faster speeds.. just assumed all saws was that way.. slowing the Hawk blade speed down.. I just cut a clock out this afternoon probably about as fast as I would have on the 788.. with slower blade speed... and used just one blade.. well two blades to be honest but the first one broke because I was messing with adjusting the tension.. guess I had it too tight at first..
