Composite fuse a tean effort incorporating composite in a BOM age

[jose modesto]

The system that i use for producing the composite fuse requires a team.
1) I farm out the building of a fuse to one of the cottage custom builders (Bob Hunt,Derek and Dale Barry Tom Morris)
The builder builds a typical wood fuse. All blocks are left solid and i request additional formers for stiffness. A proper center line is paramount.
2) The fuse is finished to a Nat's level  smooth shinny surface Note this can also be farmed out to the best finisher in the group
3) install parting line NOTE: I use string or .018 flying line for parting line
4) wax and polish exposed fuse surface
5) Protect one side of fuse with duct tape and create a dam by outlining the fuse perimeter with 1/4"x1/4" balsa stick
choose your materials for female mold (i use fiberglass or tooling resin)
With a team approach you to can have composite shell fuselage

Once you have the female mold you MUST keep the male plug. Enter Al Rabe by combining Al Rabe's wet molded balsa with a vacuum bag system you can have a lite weight composite fuse
1) purchase or create a 1/32"x8"x48" balsa sheet  Wet and wrap around the male fuse plug with ace bandages (just Like Al did for the bearcar and Sea fury
2) in female mold wax and polish to a high smooth gloss
3) place one layer of .5 glass cloth with epoxy remove as much epoxy as you can with a trowel (you can also dab corners with paper towels to remove any excess epoxy
4) place 1/32"premolded balsa into female mold
5) apply .5 glass cloth  to interior of woos shell
insert into bag  let cure for 24 to 48 hours
The fuse sides weight 1.7 oz each completed electric fuse is 4.8 oz waiting ti install tail wheel mount SPARKI HERE I COME with light building
