Measure off the collar position on the mast. Measuring
from the base of the carbon mast (not the heel), top of
the collar should be at 295mm and the bottom at 215mm.
Wrap masking tape above or below these points
respectively.
Sand the region with 80 or 120 grit paper to remove the
shine and provide a scratched surface for good bonding.
Similarly sand the inside of the collar. If using dry
paper care should be taken to avoid breathing in the
carbon dust - wear a dust mask.
If wet paper was used dry the mast and collar.
Wipe the mast and collar with acetone on a clean rag.
Remove the heel plug fastenings and see if the collar
fits over the heel plug, if not remove the heel plug as
well.
Remove the bottom masking tape to allow the collar to
be slid into position.
Mix the epoxy resin (approximately 50g) and add glue
fibre until the mix is stiff (like porridge) and doesn't
drip off your stirrer.
Apply the glue to the mast and a very small amount to
the collar (just wet the surface).
Slide the collar into position, ensuring some glue
remains underneath; remove excess glue.
Check the collar is in the right position (top at 295mm
from the base)
Remove masking tape. Clean off excess glue from the
mast and collar with acetone on a rag.
Allow glue to set. Hold the collar in position with a
small amount of masking tape if it is likely to move while
curing.
