Re: [ATM] Tool Tiles

["Bill Wheaton" <junkwheaton@gmail.com>]

Good idea bout the skewer.  I noticed that after I had cut my tiles to size
that just laying there on the mirror a few were not touching.  I was trying
to figure out a way to ensure that they do, and also, if I do a runny mix,
to ensure that it doesn't fill that gap.  That would not do at all.  I'm
thinking that it might just be the stiffness of the backing material.  I'll
try soaking it in hot water beforehand and letting it dry and let you all
know the results.

In regards to miniature re-bar...  I got to thinking, that even though the
square mesh is strong in stretching - even diagonally, it's too flexible in
bending.  Unless I was willing to construct a tortion box like structure
with it, just tossing a hunk of it in there wouldn't buy me much in
strength, so what they said feels right.
