BONDING There are four main points to the bonding process, which areoutlined as follows:1. Alignment: The tubes need to be elevated off the ground onblocks and leveled. Each tube should be supported in three pla-
ces (two supports shown for reference only). The delivered adhesive is a Proset Epoxyd. Load the Proset car-tridge in the press and screw the mixer on the cartridge. If the
adhesive is delivered in packages mix the two components care-
fully before use.The adhesive needs to be applied .010” (0.254mm) thick onboth the outside of the ferrule and inside of the tube (these sur-
faces need to be clean and free from contaminates) that it is
going to fit into. Use the included application tools in the man-
ner shown below. NOTE: Remember, excessive adhesive may cause interferencefor the bushings and will be difficult to remove later! VERY IMPORTANT!NOTE: Bonding of the tubes must be carried out in a certain
sequence. It is very important that the tubes are assembled in
an order to allow access to the bonded joints in case of interfe-
rence in the tube caused by excess adhesive. Each joint must be
inspected after each stage to insure that the bushings will fit in
the tube easily without interference. NOTE: While pushing and twisting the tubes together, thejoints need to be cleaned of any excess adhesive, with special
attention to the luff groove areas to insure that NO adhesive
runs into or between the luff grooves. 3. Splint: Once the tubes are completely assembled, the seamsand the luff grooves both need to be cleaned of any excess
adhesive once again. After cleaning, lightly tap the wooden ali-
gning aid into the luff groove to insure that the groove is
straight and lined up from tube to tube. A plastic film should
be wrapped around the joints in conjunction with a 90° splint
applied at the joint areas. This splint should extend approxima-
tely 18” to each side of the joint for support and affixed to the
tubes with tape.Following assembly, the joints should be allowed to cure for aminimum of 24 hours before the splints are removed or the
tubes are moved. 2. Joining the Splice: When guiding the tubes together, takeparticular caution to be certain that the tubes are straight and
level on their supports. With the tubes lined up end to end, the
luff grooves should be facing opposite directions. The tubes are
then pushed together while turning 180 degrees (they need to
be twisted as they are pushed together and NOT just pushed
together straight). Seite / page 12 >
