I don't know about the ABS plastic, but if it's anything like plexi and
other plastics I've used, adding "grooves (tho not groves) is a piece of
cake. Get some round, solid, lucite rods, about 50 cents each (I have 5 of
them sitting in the unused tube with the bat-hat) and lay a line of
methylene chloride, solvent adhesive for acrylics, along them out of a
syringe (available at Industrial Plastics on Canal St as are the tubes and
the rods).
Then INSTANTLY stick rods into the tube & press against the wall. Or
better yet, hold rod in position inside tube & drop a few drops along the
join line at one end, then reverse tube & drop a few drops at the other
end. The 2 pieces will meld. Stronger than mere mortal bonds. Which
configuration would ward off turbulence and whether, I planned to, but did
not discover. My thought was it would be OK.
