AMBIENT CARBON FIBRE BOOMS
Maintenance and repair instructions.
Renewing the felt bushings
The felt is easily replaced by disassembling the boom, peeling off the felt strips, noting their
position, cleaning the tube surface with spirits, to remove grease, applying new felt and
then reassembling.
Note:
When applying the felt ring, a small expansion gap (2mm) should be left.
Never overlap the felt.
Velcro felt strips with adhesive can be supplied by us free of charge by post on
request.
Repairing or renewing segments
Generally with breakages, Ambient will supply a spare segment ready for fitting. In rare
cases customers may want to do repairs themselves. For example, if a tip becomes bent
then it needs to be removed and a new one fitted.
A fitting such as a tip can be removed by heating with a blower slowly and evenly and
extracting the tip when the glue gets soft. The tip should be firmly held in a vice and the
joint heated until the tube pulls free.
Note: It is easy to overheat the tube!
Alternatively cut off the tip and tube 4 cm down the tube and reglue the coloured collar
ring and tip supplied after cleaning with spirits to remove grease. The segment will be
shorter!
We do not advise trying to remove the aluminium base of the screwlock. The glued area is
large and the tube will overheat and the metal part will deform before the glue gets soft.
Order a spare segment!
Note:
Ambient supplies this special 2 component glue free of charge in syringes. Do not use any
old 2 component glue. It will go soft when you are shooting in Florida in the midday Sun
and the Mike will drop of the boom!! We had this problem in the beginning with a normal
2 component glue from the “Do It Yourself” store. Then we changed to high temperature
glue.
The 2 component glue that we use is hard up to 150 deg C. Mixing proportions are 1:1 by
volume. Squeeze out required equal lengths of base and hardener next to each other on a
piece of stiff paper. Mix well till homogenous. Wait 2 minutes then apply to b
both surfaces
of the parts being glued and push parts together. Excess glue can be removed with a
spatula and removing last traces of glue at the joint can be done with a rag generously
wetted with alcohol or household spirits. Do not use acetone or thinners! Working time is
1 hour max. Hardening time 24Hrs.
