Table Saw Zero Clearance Insert?
I'm a little confused, my saw has a 100mm depth of cut. If I use the method of removing riving knife, then place blank insert in table, hold down with the fence. Then bring the blade all the up by 50mm through the insert. For the zci to work fully, does blade always have to be raised to 50mm, or can I lower to whatever height I would normally use it at say 18mm for plywood and I will still be getting the zci benefit? I appreciate the sides of the zci are flush with the saw plate but I'm wondering if the slot is longer does the zci still work like that? I'm sorry if I havn't expressed what I mean very clearly.
This is what I'm getting at,read it somewhere else.
" If you later lower the blade, the ZCI is no longer strictly ZC. It will be ZC at the sides, but not at the front, directly in front of the teeth. That might matter if you are cutting MFC ( Melamine Faced Chipboard ) for example."
When using saw as is with the standard large gap insert in place.As a safety thing I always adjust height of saw, so tips of teeth clear workpiece and no more. I wouldn't like to make a zci by raising blade up through blank say 50mm, then have to keep at that height to get zci effect, would lose complete effect if lowered blade down. I hope this explains my confusion more clearly.
