best way to construct a fuse

I am just wondering the quickest and the most neat way of constructing a fuse.

I am really after the info and how one of the members model is made.

It has been at Gaydon a few time and I think it is a dornier commercial jet with the engines at the back.

It seems to be a foam and glass fibre skin but I am not sure if this method is only good for round fuses etc?

Any ideas or assistance of how its done would be great.

Cheers,

Mike.

They probably still sell the wire down the shops, although circuit breakers seem more popular these days...

Rob fuse is short for fuselage. Anyway whats happened to those clutch bags advertised on here

A dead flat and straight building board is a good start. You could build the fus in two halves along the horizontal plane ( no pun intended !) then join together.
This method is described in Gordon Whitehead's book, "Scale Aircraft, Models for everyday Flying". It is now out of print and pricey!

Hi,

Thats how I have constructed the nimrod fuse but I am wondering if there is an easier way?

There are many ways. A simple method is to construct a box fuselage and add blue foam shapes to top, bottom and sides. After shaping, glass cloth and resin.

That would be a good method then melt the foam out so you had a composite body.

Another way Mike, espescially with the more rounder fuselages, is to build a central crutch the full length of the model. Mark off over the plan where the formers need to be located, prop the crutch up on blocks and slide your one piece formers on, starting from the middle and working outwards. Just make sure the formers are 90 degrees to the crutch and then you will have a zero degree datum line. My last three builds were all like that (DC 3, B 25 and DH Vampire). I've found this to be an easy method, espescially for traditional built up constructions. Jonesey.

I thought of doing a skeletal structure add blue foam in the pockets and sand to the fuse shape.

This would leave hopefully about 1/2" of foam on the fuse. Then after glass the whole thing.

Wings I have been thinking. Getting foam cores cut then get .2 mm fr4 and epoxy/vac bag it to the foam cores once all spars etc have been glued into the core.
