How exactly does this work with 5/8 stock? All my test corners had a substation gap/misalignment. I had to manually adjust he bit using a straightedge to get it fairly close.

An absolute must for me.
I bought the miter bit with the set up block. I tried setting up the bit without the block and it took a longer time and many test cuts to get it just right. The block makes it much easier and with only a couple of test cuts.

Great tool.
Makes set up easy. Just pay attention to using the correct side. One side is for 3/4 inch stock and the other is for 5/8. I marked mine as to which side is which.
A must for the locking 90 degree miiter bit.

Lock Mitrer bit
This bit does exactly what it's supposed to do. There was no need for adjustment if you follow the directions. As with most router bits there are always adjustments needed to set up the bit to exactly what you need.
I've got a Jessum Router lift that makes minute adjustments very easy, so it's a bit easier than check, lift, check, lift.
You can use this with different thicknesses of wood, but if you do use a different size of wood you may need to make some minute adjustments.
I'm very happy with my purchase.

45º Lock Miter bit
I purchased this lock miter bit to make speaker enclosures for a friend. I was looking for something that would make projects made of baltic-birch plywood joinery look better. I was very pleased with the results. I would advise others using this type of bit on plywood to first score the cut-line to reduce the natural tear-out that occurs on plywood when cutting cross the veneers.
This method reduces the surface area that shows the edge lamination of the plywood. Less need for edge banding, etc.

Works good for initial set up
This works good for the initial set up if your stock is 3/4" but you MUST test cut, test cut, test cut, with the exact stock thickness as your finished project. The first time i used the bit my corners were flawless and i was very pleased with the set up block and the bit.
