BONDING

There are four main points to the bonding process, which are outlinedas follows:1. Alignment: The tubes need to be elevated off the ground on blocksand leveled. Each tube should be supported in three places (two sup- ports shown for reference only). The delivered adhesive is a Proset Epoxyd. Load the Proset cartridge inthe press and screw the mixer on the cartridge. If the adhesive is deli- vered in packages mix the two components carefully before use.The adhesive needs to be applied .010” (0.254mm) thick on both theoutside of the ferrule and inside of the tube (these surfaces need to be clean and free from contaminates) that it is going to fit into. Use the included application tools in the manner shown below. VERY IMPORTANT!NOTE: Bonding of the tubes must be carried out in a certain sequen- ce. It is very important that the tubes are assembled in an order to allow access to the bonded joints in case of interference 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: Remember, excessive adhesive may cause interference for thebushings and will be difficult to remove later! NOTE: While pushing and twisting the tubes together, the joints needto 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. 2. Joining the Splice: When guiding the tubes together, take particularcaution 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). 3. Splint: Once the tubes are completely assembled, the seams andthe luff grooves both need to be cleaned of any excess adhesive once again. After cleaning, lightly tap the wooden aligning 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 conjuncti- on with a 90° splint applied at the joint areas. This splint should extend approximately 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 a mini-mum of 24 hours before the splints are removed or the tubes are moved.
