Greetings all,
THE FOLLOWING IS SPECULATION AND HAS NOT BEEN TRIED.
I am considering building my construction table with solid foundation
and top, then a layer of self-leveling compound, and then gluing the final
top on to the dried compound. I think that will give me a level and flat
surface.
I think this technique could also be used to modify existing tables
which are out of line.

Hi Raymond,
This would give you a flat surface if you mixed it a little extra wet and had very straight sides to screed the mixture. But remember that you need to be able to drill into the surface. Level is still up to how well you level it. I still can't see a reason for level though other then generally speaking .
Kettle river is just down the road from me. We are getting a pretty good showing in our area of 701 builders. I wish there were more flying 701s though.

I tried this very approach with unusable results. I used self leveling floor
prep for laying tile over the top of the plywood. would have worked fine I
think had I sealed the plywood prior to using the water based leveler. As a
result the water based material warped the plywood and made a huge mess of
things.
I do feel with the proper prep this technique could produce a very fine/flat
table.

Here lies the true value of this site. Someone asks a legitimate question, and he will get several very legitimate options to choose from. It helped me immensely when I started a little over a year ago.
So, here's my solution--I found a listing from a guy on this site that was equally concerned about flatness of lumber, so he ripped 3/4" OSB into 3.5" strips, glued them together to make 2x4's, and then constructed tha table from them. I did the same thing and I have to say he was right. If you cut carefully, that stuff is dead straight. It sounds like a lot of work but if you have a good table saw and a place to layout the glued pcs. waiting for drying, it really makes a good solid table. My wings are very straight.
I built two 4'x6' tables and then screwed them together so I can separate and use them individually as workbenches after the wings, and fuselge are done. Mine is 36" high, and I used the same 34" OSB for the top and left about 3" of overhang for the clamping surface. Good luck.

I just posted in another thread my thoughts on tables. I'm a bit
opinionated about tables I must admit, but I think they are a big time
waster. I find after two planes built, it is simply not worth the effort
to try to make a perfect table.
Don't waste time on the table. Make a basically flat, basically level table
buy a laser level, get a bunch of 2x4 and plywood scrap, a box of deck,
or drywall screws a cordless driver. Make simple holding fixtures and jigs
as you build, and very straight and level with the laser level and bubble
levels. You will build faster and more accurately. The worlds flattest
high quality table can make crooked parts. a couple sawhorse and a sheet
of plywood can make perfect parts. It all comes down to leveling and
straightening the parts as you build.
OK - Example build a wing. Place spar on table. Level it end to end. Attach
ribs. Screw blocks of 2x4 to the table at each rib tip. Cleco in place the trailing spar. Using plywood scrap attached to the 2x4 blocks adjust rib
tips, and TE spar into plane with the main spar (i.e. level). Use existing
holes, or clamps fasten the rib tips to the plywood holders
Your table can be crooked like a snake, and 4 inches out of level. However by shimming and, jigging and leveling you just made a perfectly flat wing.
Do the same thing on a table straight to within .001 over 12 feet ... You still
have all the same issues with having to jig the parts into alignment
anyway. SO the table being flat becomes a mute point.
Regards,
Jeff.

I was thinking of polymer or epoxy products rather than cementitious
underlayment. A temporary edging to retain the material before it sets
would be necessary. May not be cost effective, I haven't priced it out.
