<DIV>Thanks for the info Dave. Did the dowel go completely through or
partially through the rib and the panel? I'm in the process of using a =
combination of carpet tacks and bridge pins, but I'd like a full cache =
of
ammunition. <BR><BR>Terry Farrell<BR> <BR> I =
believe
the dowels went all the way through the thinned rib ends and all the =
way
through the board. They had a little bowl of pre-cut dowels =
about 5/8"
long (chopped-up hammer shanks) as they glued the ribs on. =
</DIV>
<DIV> The ribs had all been pre-numbered to avoid =
mix-ups
and they had been pre-fit to the board. The board had a few =
"waves" (not
perfectly flat) to it and they pre-fit the ribs to the board and =
marked any
places where there would be a gap between board and rib (a "dip" in =
the
board). For these areas, they used 1/8" or maybe 1/4" shims on =
top of
the rib, just for the length of the gap (usually only 2 or 3 inches or =
less). Then the pneumatic hose of the rib press sat on top of =
the ribs
and shims. Where the shims were, it pressed a little harder, so =
to
speak, to help close up those little voids, or gaps. Worked
great! </DIV>
<DIV> They glued one rib at a time and as the air =
pressure
was applied, the hose inflated, pressing the rib down and causing glue =
squeeze-out, which was cleaned up right away with damp rags and
scrapers. Air pressure was to be maintained on the press
overnight. I'm sure it came out nicely, but it was late =
and we all
went home -- besides, all the donuts were gone. </DIV>
