Dawg,

I like and have a number of Harbor Freight tools. I'll look for the
hammer drill. I have only 8-16 approx 1/8" holes big enough for
plastic anchors. That should hold the brackets until the gorillar glue
dries.

Appreciate the info,

Manjo

Jerry,

RAMSET sells a lot of stuff. Are you talking about their drills and/or
adhesives?

Thanks,

Manjo

I would drill a 1/4" hole and use a plastic (or other material)
anchor.

Not being a glutton for punishment, I would probably find another
outlet for my artistic talent than a mail box post. <G>

Glenn,

I'll use plastic anchors.

And I'll look for a hammer drill. When I'm done with the granite, I
can use it for my real passion: delcate clock repair :>))

HAppy Holidays,

Manjo
