Scratchbuilt 1/12 Hurribomber: Part 1

By Thomas Christen

Fuselage structure with brass rods.

I was lucky to get an old pantograph. So I could transfer the formers to the plastic sheet from original drawings.

The time-consuming cut-out with a Dremel.

Upper formers provisional fitted with Plasticine. Just to find out how it looks!

The next challenge: Center-Section! First milling the 12-sided main spars, then the 0.5mm slot with a side-milling cutter.

All parts temporary composed. Beer-can (empty! J..) as raw-material! Excellent suitable for stiffeners.

Made a deep-drawing stamp for all stiffeners & brackets. Punching out the holes with self-made dies.

Two brass sheets riveted together as template for punching out the position of fasteners on the stiffeners.

Wondered how to imitate rivets on the stiffeners: Found lead solder balls on eBay (available 0.2-0.75mm dia).

Lacking in drawings of trunion-sleeve I had the lucky opportunity to take measures on the occasion of a visit to Hawker Restorations. Thanks again H.R.!

Made (very thin) flanges for cooling-duct from aluminum rod.

Both main spars almost finished. Made the smallest hex-heads from hex-shaped stretched sprue and thin slices. The bigger ones with the nutter of RP Toolz.

That’s it for the moment.
