I bought a new to me saw and my noobishness is showing concerning the fence that came with it. It's not the original to this saw and I have no idea what brand it is, but what has me befuddled is setting it and using it. Does one have to both > adjust the small top knob & use the lock handle each & every time when setting it? It may be just not dialed in, but seems no better than the crapola I replaced,
Unless I'm missing a step or two I'm still back to measuring from front & back of the blade to assure squareness
Thanks for any thoughts or pathways!
