One inch holes in slate

[DeadCrab]

In looking at schematic diadrams for three-peice slate, there are 1" holes around the periphery, I assume to accomodate the rail bolts.

If the rail bolts are going to be 3/8" or less, why are these holes 1" ?

rails have to be straight so there would be an allowance of sorts for the plus and minus of the machine made rails

And if the rails are solid wood, they change shape over the course of a year with the change in relative humidity. Having oversided holes allows them to move without binding anything else.

The oversize holes would allow a few fractions of an inch of alighnment discretion when the table is assembled. The mechanic would be able to make small corrections until the table was set up correctly.
