Megapoxy for limestone blocks

[Faraut Philippe <pcf@zzzzzzzzzzzzzzz>]

Thanks everybody!
I think that I will use the method suggested by John since I will need
a joint spacing of approximately 1/4 inch. I will also try to find the
hard plastic shims to control the thickness. The stainless steel rod
pins suggested by Chaz are also a good idea since the sculpture is also
a retaining wall.
Chaz, can you elaborate about the need for carbon elements in the
respirator? I have always used a basic respirator when working with
marble, is limestone different?
