I’m having all kinds of problems getting my pieces to sit nicely in their dados.

I’m Making Dan phalens router table and I just spent the last hour trying to figure out the height of the two interior walls. I know the dado’s are .25” deep and from the divider up to the top of the sides is 17”. Therefor the interior walls must be 17.25”. Finally got it to seat. i was checking the height by placing a square on the outside wall and running it across the interior wall.

What are some ways to make sure it’s seating all the way across it’s length?

Do you have curved cauls? That would put pressure along the entire length of the joint. Should help everything seat correctly. I use some 2×2’s from the local Home Depot. It even helps that they were never straight to begin with. I just picked some that had about 1/8” of curve along the length.

I have not, I have read about them. I will give them a shot. I think I saw a video on how to make them.

Seat with a mallet & block. You can feel/hear when it’s fully seated.

I did try that with some success Mark. I don’t know what was throwing it off. I almost cut it too short Lol.

I’m going to make some cauls tomorrow cause I’m sure I’ll need them when I have to glue it up.

As it is I had to remake the interior panels because I was supposed to use 1/2” material for the slides. When I took it off I measured and good thing cause it was 1/16” too tall.

You could draw a line 1/4 inch from the edge of the panels.

Are your dadoes a consistent depth and have a flat bottom?

Just my opinion but if it takes hammer and a block of wood the put it together the dadoes are to tight. widen them up a bit.

If you haven’t already made some, these things work great for gluing up dados (and corners, and shelf butt joints, and… well, lots of ‘cabinet’ type stuff).

Yes I used a router plane after to make sure they are.

Kevin,

I would rethink glueing. I don’t think standard wood glue alone is adequate with plywood. Epoxy would be better. This is because you’re dealing with mostly endgrain (actually worse than endgrain) on almost every aspect of the joint. Sizing the ends with glue is an option. In any plywood carcase, I think screws are the best route. You don’t even need any glue. You can countersink and plug.

A router plane gets your depth uniform but if the dados are too tight you either need to

1. Widen the dado (side rabbet plane or another pass on whatever you cut your dados with).
2. Reduce the thickness of the wood going in (block plane or sand).
