- Slide the base spar into the drum unit until the two holes are in line, insert the M5x12 screw (after putting some silicone filler in the
hole in order to reduce the stainless steel / aluminium electrolytic couple) and tighten.
- Install the boltrope prefeeder; ensure it is the right way up, see diagram below.
- Secure with the 4 screws ø3.9x9.5
- Insert an aluminium coupling sleeve, put some silicone filler into the hole and position a MSx8 screw (do not tighten or it will be
difficult to put the second screw in place).
- Put a second spar into position, put some silicone filler in the hole and position the screw (once the two screws are in position they
may both be tightened). Wipe off any excess filler with a cloth.
- Insert PVC liners as you go along (ensure they are flush against the prefeeder)
- Repeat the process until only one spar is left
