I built an extension table on my saw 2 years ago when I purchased it.
However, in the 2 years of use the melamine has chipped fairly badly.
It also was not attached very well and is sagging.
My design used a frame of 1 x 2 (3/4" x 2" real size) with the 3/4" melamine attached to the frame.
The frame also has cross-members about every 12 inches.
Finally, I mounted my router in the table and when the router is mounted the table sags a bit (I have a brace that I use to prop up the table when using the router.
Does this design of a single 3/4" sheet table match what you have done?
I remember reading that some have used 2 sheets of the 3/4" for the table in which case I'm confused.
My rails (that I attached the extension table to" are "L" shaped and the holes to mount the table are 1 1/4" below the surface of the table.
If I use two sheets of 3/4" then the thickness of 1 1/2 inches puts the bottom of the table below the mounting holes.
For those that use the 2 sheets how do you mount your table?
Thanks,
Jeff
