Dimension 'X' Questions

RvRamblers

I am having a table made for my large BGE and I am a little confused
about "Dimension 'X'".  The plans (both Whiz's and BGE) state that it
should be 15 inches.  Whiz's plan say 15 inches when using the ceramic feet between
the BGE and the sheet of slate.  BGE plans state 15 inches and then says
make sure you use a 2 inch paving stone.  This will raise the BGE 2
inches resulting in 13 inches between the top of the paving stone and the top of the table.  I measured the BGE and it appears that 15 inches from the top
of the slate to the top of the table will clear the hinge on the egg
without the ceramic feet or the paving stone.  Should I
decrease the 15 inch dimension to 14 inches to compensate for not using
the ceramic feet?  Also some owners are increasing the hole diameter  to
22 inches.  What are the thoughts about that?
Thanks in advance,
Ken Manning

Basically think of it like this. from the top of whatever your egg is sitting on to the top of your table should be no more than 14.5 inches. You might could go 14.75, but 15 inches will be cutting it way to close. When the dome is opened the spring assisted hinge drops down slightly. On the hole size, if you are placing the egg lower in the table than the 13 inches it would be on the bge plans (15 inches minus two inches for the paver), then I would make the hole a little larger as the egg is tapered. This is for a large egg. Hope this helps.
