I know this might seem like a crazy question but I have the bosch evs1617 router mounted on a bosch router table,,and I cant seem to get the bit to raise high enough,,,,unless of course I raise it out of the collet a lot which is dangerous,,i have got the twist knob raised as high as as I can get it and even took the router out of the housing and pushed all the way to the top as far as it would go,,and it still isn't high enough,,im not the smartest person so any help would be appreciated,,,i honestly do better using a router hand held,,,
