Enlarged Table System

I have not yet completed the rebuild of my Height Adjustable Tilting Out Feed Table to increase its size but it is getting there. I needed outfeed table support this week so I hurried assembly.

It along with a couple floating extension tables certainly eliminates the complaint of "Table Too Small". I had a couple sheets (60" x 60") of baltic birch plywood to cut and it certainly did the job.

Notice the two pieces of train rail sitting on the out feed table. Together they weigh about 14 pounds; heavier than most of my cut offs. This weight has no adverse effect on overall stability.

that's nice Dusty,
is it easy on, easy off---or is it a semi permanent set up

I would not call it a semi-permanent attachment because it comes off too often; however, it is relatively easy to take off. I would guess about a minute to minute and half. My standard day-to-day configuration includes the table. That is why I worked to make it Height Adjustable and Tilting.

If you want it to be quick, use the angular adjustable leg (see previous postings). To still have the Adjustable Tilting Table but you also have the support leg to mess with.

You can see in the photos that I left the receiver for that leg on the Mark V.

I would like to add my thoughts to maybe--or maybe not--improve on your design.
One way to help keep your table nice and flat/ridged would be to add some aluminum angle to the sides of your support boards under the table. If the boards are 3/4 thick use 3/4 angle. You could add the angle to just one side of each board, or both to make it extra ridged. This would not add too much extra weight or thickness to the underside of the table.
If you are not concerned with the overall thickness of the table, you could put 2 pcs of 1in angle back to back, forming a tee under each support rail. This would be even more ridged, but would protrude more from the bottom.
Just a couple of options to think about.

Thank you for the comments. They are much appreciated.

Weight is a critical issue. That is why I used the baltic birch plywood rather than MDF. I could be less concerned with weight if I used the support leg but I wanted it to be cantilevered instead.

Are you going to detail how you mounted the table?

I wonder if the table itself could have been made from 1/4 baltic birch?

Perhaps I'm wrong but even IF there was a some flex I think this table could have a small degree of flex and not effect it's usefulness. 1/4 inch ply would be a lot lighter, am I wrong?

No, you are not wrong. The table does nothing more than support materials as they come off the main table (if used as designed at is). I tend to misuse it as work space.

I even gave thought to using an artificial material (a type of sign board) that is a compressed fiber. I did not because it is easily damaged (like Styrofoam only a bit harder).

BTW, there is some flex in this table. More than I thought there would be.

Yes, I will add a rudimentary Sketch Up drawing of the bracket.

Here is the sketch for the Table Brackets.

There are some minor differences between the older 510 tables and some of the newer tables. The differences involve milling aids that were used when the tables were built. These differences will impact how these brackets actually fit. A file will be needed to "shape to fit" as required.

DO NOT REPLICATE, THERE ARE DIMENSIONAL ERRORS IN THIS SKETCH!!

I think maybe having an adjustable mid-angle support that ties back to the lower tubes would be a helpful way to adjust and stabilize the whole table.

The attached drawing contains what I now believe to be the correct dimensional values.

Drawing removed because it contains errors.
