<DIV><SPAN class=265244815-30042010><FONT face=Arial>if you are near a pretty
thick edition of the yellow pages, you should be able to find a listing for
someone who does plastic vacuum molding or prototype molding. The vacuum
mold system is perfect for large non-critically dimensioned and low
production custom pieces of plastic. </FONT></SPAN></DIV>
<DIV><SPAN class=265244815-30042010><FONT face=Arial>The mold core will be made
of wood and shaped like the inside of the battery tray. A sheet of plastic is
heated then lowered onto the core and a vacuum pump will draw the plastic tight
over the core. </FONT></SPAN></DIV>
<DIV><SPAN class=265244815-30042010><FONT face=Arial>A basic tray, or several
smaller trays for pairs of cells can be made up pretty
inexpensively this way. </FONT></SPAN></DIV>
<DIV><SPAN class=265244815-30042010><FONT face=Arial>If it is a size battery
type you install often you could probably get a better price for multiple
pieces.</FONT></SPAN></DIV>
<DIV><SPAN class=265244815-30042010><FONT face=Arial>Here's a shot of a rather
sophisticated production vacuum forming machine at work. Smaller shops may have
older machines but your needs are not critical. Just be sure to specify the
correct type of plactic that will be acid resistant.</FONT></SPAN></DIV>

RE-wrenches<BR><B>Subject:</B> [RE-wrenches] Ideal platform for flooded type
batteries: opinionswanted<BR><BR></FONT></DIV>Hi, Mechanix~<BR><BR>My
"customer du monde" has a dirt floor in the battery space but he's willing to
build something on which we could place his "wet" type batteries.
<BR><BR>Concrete is strong but it also tends to begin dissolving when battery
acid gets on it. Been there, seen that, didn't like it.<BR><BR>Wood could be
strong but what about the dissolving problem? Would pressure treated wood be
better than white wood, redwood etc.?<BR><BR>OR: what else would the group
advise for a support
structure?<BR><BR>************************************************************<BR><BR>The
above questions assume that whatever we do will probably get wet, but that may
be too pessimistic. Could someone give me a mini-review of plastic trays which
would protect whatever goes beneath? <BR><BR>I'm pretty sure polypropylene is
the right type plastic but short of custom welding by a plastic
fabricator...where can I find trays which fit OK with floor scrubber type
battery case dimensions?<BR><BR>Thanks all around,<BR><BR clear=all>Mick
