The slate is one piece. I believe it is about 1 inch thick. Heavy, but two strong people can move. it.
on the rails, take the aluminum molding off the sides with a phillips screwdriver and then using a 7/16" socket, remove the rails. be careful when unscrewing them....they are T nuts inserted in the wood.
After removing the rails....mark them underneath and on the table so they can be replaced in the same side.....you can remove the slate.
Then turn the table on its side and remove the legs. then you can transport it wherever you need to. Installation is reverse of the above.
You can place playing cards under the slate on the beams to level the slate before putting new felt or leaving existing felt on the table.
Make sure all the return rails (if not drop pockets) are sturdy and attached well. Also, pocket areas.
Good luck.
