Domino 700 Issue

[Birdhunter]

I've had my Domino 700 several months and have used it to do bigger projects than my Domino 500 can handle.

I have a problem I've never encountered before with either Domino.

I'm cutting a 8mm mortise 25mm into the end grain of an Ipe board. I'm getting a face full of chips!  The 700 is hooked up to a Festool vac and the vac has a fresh bag and has lots of suction. I have a Seneca shim installed on the Domino 700 and I'm using the 15mm depth stop.

Am I doing something wrong?

My next step would be to make a clear plastic shield over the top of the Domino to deflect the debris.

The only thing I can think of is that being ipe, and end grain at that, your chips aren't the usual sort that are easily pulled in by the dc collection of the Domino. Esp. when you've cut other wood and not had this problem, yes, no? [blink]

Have you tried the Domino again on some other wood you have never had a problem with before since the problem existed with the Ipe? Just curious whether it's really the wood or something random that has come up with the Domino.

I've never seen this problem on any other type of wood AND I don't have the problem cutting the Ipe motives with the grain. It only happens cutting into the end grain.

I ended up taping a piece of clear flexible plastic from a document sleeve over the top of the Domino to keep the debris out of my face. I had granular debris all over the floor when I had finished cutting 32 end grain mortises.

Ipe (Ironwood) is incredibly hard, especially the end grain. I found that feedrate is the key to getting the mortise cut into Ipe's end grain. Too fast and the Domino stops cold. I found the controlling the feedrate with my body as opposed to with my hands gave me better control. It's the same technique as using a hand plane or a cutting tool on a lathe.

Just in the past 3 days, I have experienced this same phenomena but with African Mahogany.  Some particulate even got past my safety glasses and into my eyes.  I was also cutting into end grain.  I checked the suction and it was good, bag also not full but for seemed to be filled more toward the suction connection.  I pushed on the bag and it didn't happen again.

I have the Oneida UDD on my CT22 and I don't have any issues with cutting into end grain of Ipe or Rosewood.  There is more residual chips/dust at the bottom of the mortise using the Domino 700 than I experienced with the Domino 500.

  No matter what I plunge into with my 700, if it's a full depth mortise, there's always a trace of chips in the mortise at the very bottom, even on soft wood like Cedar.  I just remember to check all the mortises before glue-up for chips.
However, I haven't gotten the chips in the face yet while using it.... [blink]
