TOMBSTONE FICTURE

[matchy]

I am considering Building a Jig for my HS1 Rotary Table,

There is a spigot in the centre of the rotary table,


What is the best possible size of the Base plate to

turn a spigot on?

i want at least 2 vices mounted on oppisite sides,

I was thinking of using a Base of alloy, 12 x 12 x 3 inches thick
with a spigot turned in the centre for registering on the table,

Then bolting the sides on,
