Subject: table for milling machine

Quite a few years ago I bought a used Burke (horizontal) mill.

The table was in bad shape with numerous craters where t-nuts had been
pulled up through the top.

I milled the table flat below the surface of the t-slots and bolted
a 1" thick piece of to the top and cut new slots.  A friend then
surface ground it for me.

As one might have suspected, after a period of months the bolts holding
the top began to telegraph to the surface.

I would prefer to build a new table top from a slab of grey iron
(like meehanite) or buy a table off a junked machine.  I seem to 
remember also that there was a source of moderately large positioning
tables (5"x18") for lab use, but I cannot recall the source.

Does anyone have any suggestions?

Richard,

What does this mean?  The bolts are somehow raising the surface of the steel?
The bolts come up from the bottom or down throught the new steel?

>tables (5"x18") for lab use, but I cannot recall the source.

I'd make a pattern and have it poured.  Most tables are somewhat hollow to 
save weight as I recall.  Also, you could at least core the vertical slot
portion of the T-slots.

Best regards,
