Domino XL joining mitered edges on 3/4" material?

[koschak]

Hello all,

I just purchased my first Festool products and have a question about using them in another application.
I usually join mitered edges of hardwoods by using my lock-miter cutter on the shaper, but a customer has
two columns to wrap with plywood. Is it possible to rip the plywood with the TS55 at the 45 degrees on each sheet
then plunge in dominos with the 8 mm bit? Or do i need to adapt down to a smaller bit for this application?
I just purchased the TS55, 103" track, CT-Midi, and Domino XL! I can see I will be buying a lot more blue and green tools in the future!

The 8mm bit in ¾ won't be good. Especially since you want to do it at a miter.

Get the adapter and smaller bits from Seneca. Also get the two domi shim plates. Using them to reference in ½ and ¾ ply make life very nice.

Also check out the supplemental guide by Rick, I believe there are pages in there about miter joining.

Ripping with the TS55 on 45 is one of the things it shines at.  I have done exactly what you propose, however be care full about the placement of the plunge, needs to be near the extreme inside. I thinks I used 6mm Dominos, cut them to under 30 mm length, and plunged only 15 mm each side, the minimum of the 700xl will do. Registration is tricky, if I had to  do that particular mitre very often I might think about getting a 500.

Come to think about it, in your application, the Dominos could be exposed inside the mitre, and cut a little longer, as they would be hidden inside the column box. I know I did not explain this well. A picture would serve better.

This doesn't completely answer your question - but i use the seneca 6mm bit with the 3/4 domiplate on the 700, with the height setting at 10mm and 20mm plunge depth both sides for reinforcing miters in @7/8" with 6mm x 40mm dominos. it registers near the inside but works well.

i didnt want to trim 8/50 dominos - but i had 6/40's and the 6mm special bit, so i found a way to make that work - the same set up might work in 3/4" stock but i havent tried it yet - i think it should be pretty close to blowing out. i can give it a rip tomorrow and confirm / deny. i'm right in the middle of an all miter build with 1" stock so this set up is in action anyway

By the way... If you want to plunge a more shallow cut, take the plastic shipping ring and get it down to 10 ( or even 5) mm and use it as a depth stop. I have never done it, but I know others have. Works great from what I hear.

Like others have suggested, you can use a more shallow mortise and cut down a tenon to size. Alternatively, you could cut the mortise before you cut your miter so that the tenon is at a 90 rather than a 45.
