Domino: Lesson learned

[iamnothim]

I’m still getting acclimated to my Domino 500.
Here’s what I learned yesterday.

Hydraulic force is stronger than hardwood.   If you think your domino is stuck when you are pounding it into your glued workpiece, it’s probably from excess glue in the bottom of the mortice.
Continued and more forceful hammering will split the hardest of hard woods.  Tiger rosewood for example.  The only upside is the fracture already has glue on it from the mortice and can be quickly clamped.

Not being the sharpest tool in the systainer, it took me three times and a lot of excess glue to figure out what I was doing wrong.  I also selected a 6mm domino for 20mm stock, which in hindsight should have been 5mm.

Done that.

Now, I just smear glue on both sides of the tenon. Doesn't take much. Seems to hold just fine.

If the tenons had a groove along their length, the excess glue would have an escape route so to speak.

They do have full length grooves along the rounded edge.

Me too.

I now plunge my mortises so the total depth of both sides of the mortise is 5mm more than the length of the tenon to allow some room for any glue that gets pushed to the bottom.

Has happened to me also and like you mentioned, clamp the split pieces right away and you'll never notice it later.  The hydraulic pressure sure squeezes the glue out everywhere [eek]

I do that, too, Jay. 
I learned my hard lesson when I forgot that the Domino was set 5mm deeper than the tenon then cut a mortise straight through a piece of flat stock.  That's a lot harder to fix!  [scared]
