Fixing a mistake made with domino xl

[PaulC127]

Hello

I am working on my first project using a Domino XL to make a large, heavy table top and base. I used a story pole for aligning the mortises and stupidly forgot to account for the added thickness of the story pole in my first mortise.  The hole is a little closer to the surface of the table than I'd like and I'm wondering a out the best way to fill it. I could glue a domino in the hole and cut it off. Alternatively I could fill it with epoxy.

Any suggestions would be appreciated.

Also what's is the recommended spacing on larger pieces? I'm using 7'x 6" x2" white oak pieces edge glued. I placed two Dominos at each end 3" apart and then one every 1 2"  ( 12mm x 140mm) I think this is sufficient but could add more if necessary.

Thanks Paul

Glue a tenon in it and cut it off.  Let the glue dry and ideally use a pull-stroke fine cut saw for the best results.

Then if you have to, recut the mortises.  I've done it many times with the 500 and had no issues.

As I read your spacing question, you are gluing up 2" thick pieces that are 6" wide and 7' long.  I think spacing every 6" or so down the 7' length should be fine.  There is plenty of surface area across 2" so I don't think you need to double up on the dominos across the 2" width for a tabletop.  They will help with alignment with the 6" spacing, but I don't think you need them for strength.

Neil nailed it - as always. [big grin]

Here's a couple more thoughts.  As Neil suggested, the only reason to use Dominos in an edge joint is for alignment.  Unless your domino is perilously close to the surface, I wouldn't worry about it.

Also, I couldn't tell from your post whether this is your first project with any Domino, or just the first with the Domino XL.  If you are new to the Domino, don't be surprised if some of your mortises are off a tad.  There is a learning curve to the Domino.  If you hold it wrong, it can easily put an angle on the mortise that you didn't want.  If that happens, just use Neil's method and redo that mortise.

There are several threads with helpful hints on how to use the Domino if you find this issue.

And Welcome to the Fog!!

Thank you gentlemen.

Not only is this my first experience with a domino machine, it is my first festool.

I did exactly what Neil suggested and inserted a trimmed domino. It might not of been necessary and there is plenty of material but  I wanted to support the surface just in case. 

The alignment has gone well so far, I laid it out carefully and have room for mistakes. This is first experience with the domino machine but not my first table. ( I'm semi- pro)

Thanks again for the help  and I look forward to being a member of the community.

If you are new to the Domino, don't be surprised if some of your mortises are off a tad.  If you hold it wrong, it can easily put an angle on the mortise that you didn't want.  If that happens, just use Neil's method and redo that mortise.

Depending on the circumstances, it may be better and/or easier to make a Domino fit the bad holes instead of filling and recutting the hole.  For the angled holes mentioned above, you could just cut the Domino so it is skinnier and fits into the angled holes fine.  For offset holes, up-down or left-right, you could trim one face of one side of the Domino and make it fit OK.  You would have less overall glue surface since you made the Domino too thin, but it would still be OK with all of the other glue surface.

Have also experienced occasional D700 misalignment problems due to the angle between the fold down fence and the rubber gripper pads ... have considered removing the pads altogether ... has anyone else had a similar experience?
