1) It brags about using the Domino as a registration device, comparing
it mainly to biscuits. I'll give them that one, but I don't know how
far I would go. The tool cuts one mortise perfectly, but them you cut
an oversize mortise on the other side to allow for "inconsistencies".
How do oversize mortises make better registrations? I haven't ever
used a mechanical fastener to line my work anyway; I use a pencil mark

If I'm not mistaken they mean "oversize" in mortise _width_, which would
have no bearing on face to face registration, not thickness, which would.

This mortise width wider than the tenon ostensibly gives you some wiggle
room to say, align the top of an apron with the top of a leg and still not
weaken the joint, or to use multiple side by side mortises without undue
precision/fuss.

4) I know this is picky, and maybe like any dedicated machine, "it is
what it is". Again, from their FAQ:

Q: Can I choose my own individual mortise width?
A: The Domino® joiner has 3 preset mortise widths that work with the
Domino® tenons. It is not possible to cut other mortise widths.

I can't see a grand for a machine that cuts only three sizes of
mortises. I know Festool will think that it has provided all the
popular sizes used today, But for grand, I would like a little
flexibility.

The widest mortise is 1 1/4", but the widest tenon is, IIRC, 1".

The largest tenon is apparently 3/8" thick, by 7/8" wide, by 2" long.

That begs the question of what is keeping the woodworker from making his own
loose tenons, as I do when using the Multi-router?

Does anyone know the radius of the curve on the mortises? IOW, which radius
roundover bit would you use to make your own loose tenons, would be on the
questions I would want to have an answer to prior to buying.

While it may not appear important, making loose tenons that fit well is not
all that quick/easy of a task to setup initially. DAMHIKT.

The biggest limitation that I see with the Domino thus far is that you're
limited to a mortise "depth" of 1" ... I don't think I could live with that
for many chairs and large tables.
