Got the lead on my 48" Diston tweeked to prefection ended up between 1/32 and 1/16".Now if I understand what you have told me before ,the lead is particular to the saw if I rite that on the wall and put that saw on it the future I can set it to that spec. and be correct.??The saw cut ok with 1/8" lead but i noticed it cut thicker boards than usual.Also the red line laser usally shows up on the fuzz after the cut it didn't until I pulled it over a bit.A good indication ,I have found,is too much lead will tend to pull the last board away from the back headblock.Frank C.
