LASER 260

- Cowling -

The original Ultimate 10-200 cowling, after arrival

top cowl

bottom cowl

one additional carbon layer added to top cowl for more structural stiffness

mounting top and bottom cowl for correct alignment,
because they don't fit by nature ...

and the result from inside, holding shape by using 8/32 screws
(you clearly see the difference between carbon and fiberglass)

as you can see, the bottom cowl dosn't fit to the Laser firewall (known problem),
because the Ultimate engine mount is a little bit smaller, than the Laser engine
mount - therefore some adaptation need to be done, to get it in position ;o)

after cutting bottom cowl to fit firewall

 preparation for special "cowl gluing", by forming cowl in place with straps & stuff
(russian method, but very effective)

adding 3 carbon layer for stiffness and getting the shape stable (inside cowl view)

cowling mounted on the "real" firewall to check alignment ... fits perfect

front view

add an additional carbon layer to bottom cowl

preparation to install camlok fasteners

final look ;o)

top cowling installed

total view, but not in final position

lower cowl doesn't fit, because modifications of exhaust system (right side)

... Oh boy, there is still some work to do ...

fix cowl in place and correction of cowl downward angle

cowl modifications started, by gluing mould ribs to bottom cowl

front view with all ribs in place

filling form filler between ribs

grinding form filler to final raw shape

stopping of final shape (side view)

resinate mould with three glass fiber and one carbon layer for structural stiffness
(right sie view)

bottom view

top view

cowl grinded and prepared to make a new mould out of it (inside view)

outside view

left side finished

cowl primed prior mould creation

new moulds for upper and lower cowl need to be created,
based on the existing cowling

bottom cowl made out of the new mould;

with mounted propeller to adopt the cowling perfect to the prop spinner

final spinner adaptation done to get a smooth transition between
spinner to the cowling and get ready to create the final mould

final prep of lower cowl, prior mould creation

mould for
lower cowl created and waxed

coating of the first
epoxy layer, done by Udo

lower cowl done with 3 layer 400g/m² carbon and 1 layer 100 g/m² glass fiber
and pre cutted
