Domino Depth and other questions

[dr.r.lam]

Hi FOG!

New user here. Still yet to buy the Festool kit needed, but I was planning my first project and had some questions.

I will be attempting a sliding cupboard on castors (for holding recycling bins), to be made from 18mm plywood.

I am putting in some side rails to stop the bins sliding out, to be held in place with dominos (pre-emptively selected the 6mm x 40mm, given I'm using 18mm ply). What is this joint called?

The plunge limit of the Domino 500 is 28mm. I can cut the through mortise on the rail.
I have no idea how to get the full depth on the front face. I'm not sure that this is even possible, because the cut out for the width of the rail is only 40mm, far shorter than the plate of the Domino.
An alternative would be to cut a rabbet (?) in the end of the rail. This means I would only still have a max depth of 28mm, but I could increase the length of the domino in the front face.

Any advice would be most welcome!
Thank you very much in advance!!

Reading this forum has given me so many ideas, and is really inspiring for me to start making my own projects!

Best regards,
Richard.

Welcome to the FOG  [cool]

I would call that joint a single finger joint if that even a term. IMHO that joint type have enough glue surface and structural strength that you don`t need a domino. Unless it is for aesthetic purpose. In that case make the mortise even shorted like 10mm and cut flush.

Perhaps more experienced FOGer`s will come with a better solution.

Why even do the inset? Why not just cut the anti slide out rail to the exact width of the carcasse, then do a dominoed butt joint to the panel?

If that makes the glue up too complicated, then you could also attach it later with Pocket screws on the interior face of the rail that would screw into the casing.

Thank you for your suggestions!

This is what I was thinking with the design (in my limited knowledge).

The shelves are attached to the faces by domino-strengthened butt joints. These dominoes are oriented in the front-back direction. This happens to be the same direction as pull on the handle attached to the front face (as it is a sliding cupboard). The addition of the dominoes in the rails would prevent the butt-joints separating somewhat, strengthening the overall construction.

Many thanks for your thoughts and advice.

Thank you,
R

Good thinking... [smile]

I'd assemble this whole package with the side rails. Domino the side rail and the side panel to the maximum depth possible. Then I'd remove the side rail and there will be a shallow Domino pocket in the side panel. Put a 6mm brad point drill in a drill press and cut the Domino pocket to the desired depth. You should be able to clean up the pocket within 4 passes.
