Hi Ralph ...
the opposed linear gap set is basically a set of pipes on one base with
another set of pipes on another base set the pipes are set about 1/2"
apart ( for easy cleaning) but here is the neat part about it ...
the second set is placed on top of the first set .. the pipes meet at
10 and 2 oclock instead of 9 and 3 with a single linear gap set
=================== <-- base 2
O O O O O O O O O
O O O O O O O O
=================== <-- base 1
the gap set is adjustable by moving base 1 and base 2 apart (oppositely
from each other) and if you want to reduce the number of gaps that are
open simply close down one end more than the other and the pipes on the
end contact each other ( altho the bases arent paralell any more and the
first few gaps are closer to each other than the end ones) but i really
dont see any harm there..
I use 1 screw per tube ( in the middle of the tube ) and when it is
tightened it causes that bowing to occur in the middle of the tube (
right where we want it ;) ) which reduces the typical end sparking
seen in close set RQ gaps ( linear and circular)
i use the mounting screws ( end ones) on base 2 as the input / output to
the gap...
