Because the grey hdf makes so much fine dust, which covers the whole workshop, no matter how close you keep the vacuum-cleaner, I decided to router out the miter slots first. I had the options of 6, 8, 12 or 22 millimeters, if I wanted to do the slots in one go. So, the slots are 12 mm. That should be enough for hardwood runners I guess. I did both table saws, after 18 months I should be able to start using the completely homemade table saw that's in the other side of the table for cross-cuts.

The new top is about 12 mm higher than the existing table, the slots are 7 millimeter deep so when a sled is used it will run over the working table.

We managed to get as deep as 4 millimeters recess for the insert plates.

After looking carefully at the options for a fence, the decision was made to stay with the T-style fence, but instead of making some kind of C-clamp to tighten it to the bench, we decided to convert the old fence from the first crappy McKenzie table we had. It turns out that the handle works more or less as a C-clamp, although on the old table it was clamping at the back. So we will have to shorten the threaded rod, turn the handle up side down and make a new clamp block.

The shape of the old fence clamp routed out the base of the new T-fence.

Mounted to the base.

And it will be used upside down.

The second layer glued on the base. The T-fence clamping system will be made out of 3 layers of the hdf. We are going to mount the old fence we made from plywood, just because it's straight and we're happy with it.
