1. DO NOT reference cutting height from the bench top. Stated another
way always use the fence to reference your cut and be sure the Domino
base does not accidentally come in contact with the bench surface.
This should be the practice when cutting biscuits slots with a plate
joiner also.
2. Using the indexing pins to accurately index is almost too much
trouble and difficult to calibrate perfectly for mating edges.
Basically the left bin has to be in perfect registration with the right
pin in relation to the cutter cutting width. I normally cut a wider
slot/mortise and that allows me a bit of wiggle room. This has never
been an issue once I adopted this method. YMMV and I suggest you try
before taking my word for it. You may be perfectly happy with the results.
3. The assortment Domino kit is a pretty good deal that includes
cutters for all the included set of domino's.
4. Be sure to use/attach some form of vac to clear out the mortises.
Most all of the above suggestions are not unique to this tool as they
are a good suggestion for plate joiner also. If you are familiar with a
plate joiner/biscuit cutter you will have this tool down in a snap.
There are really no surprises.
