Default Bit depth in a collet

Short stroy long.

I can't remember the different number of threads this has appeared in over the months I've been here and sorry I can't recall the most recent one.

All I can remember about the thread and post is that one member said that he/she had never seen any instruction related to bit depth within a collet.

I was into my Spring cleaning mode in the shop and came across my very old Craftsman router along with the much deteriorated manual. Here is an excerpt from the instructions related to bit depth in the collet.

I usually bottom the bit then pull the bit out 1/8" to 1/4"

The consensus is that if the bit is set all the way to the bottom, the collet won't tighten it, since it is pushing the bit down as it tightens. It was also stated that Freud doesn't warn against that.
If I let my bits drop to the bottom of the collet in my PC 890, I would lose them, as the shaft hole is that deep.

Never, under any circumstances, combine a sleeping pill and a laxative on the same night.

For 1/4" shank I bottom it and pull it out about 1/4"

For 1/2" shank I bottom it and pull it out about 1/2"
