I have 2 different sizes of phenolic tubes, 3/16" brass tubing, and some end caps that i machine for the 3/16" barrels to slide through. The larger of the 2 tubes will need to be trimmed to fit the fuselodge and go back into the scoop. If you want to get real picky, the end of this shroud has a slight bevel to it. The small tube will need to be cut to size and the end caps glued on to each end as well as the venting holes drilled out around the barrels. You can then slide your 3/16" brass barrels through the end cap holes and glue them into place.Make sure you cut the smaller of the two tubes to the right length. This whole piece will not be that long because it will hit against the nose of the fuselodge when sliding it into the larger tube. There is a little amount of play between the tubes and you will need to shim it out with some thin material. I think i slid some 1/32" balsa in 4 spots to keep it all aligned. The wall thickness on the smaller tube is pretty thick and will need to be drum sanded out in order for the barrels to slide through. Unfortunately this size material does not come with a thinner wall. At least none that i have found.
