So after a few weeks of producing my Brian Taylor Typhoon kits for Sarik Hobbies it's back to the re build.
Next up was to re-establish the exact engine thrust line for the OS 120 E so I could get the cowl nose ring and spinner back plate positioned.
To mount the engine I used two 20 mm x 20 mm aluminium angles as beams with the old aluminium crush plate as a spacer just behind the engine. These ran from the back of the tank bay box forward and was glued and screwed to the top of the tank bay box.
Pic below of engine bearer beams and the spacer.
Engine bearer beams.
Still nice and level.
Spinner back plate positioned.
Engine bearers being glued in. Later countersunk screws where added.
I made these to hold the engine securing bolts. Old idea to stop bolts turning when tightening the nuts.
Engine being trial installed.
The old brass tube engine braces were re-used. Tank positioned to see where the inlet lies relative to the carb spray bar.
Retract air bottle sits here in a cradle shaped to hold it. Siliconed into place.
Air flow from the cowl front, over the engine and out the bottom was achieved by following the full sized principle. Formers were dremelled to create apertures.
A shelf, just above the tank bay box floor (fuselage is up side down) was made up against former 3. The flight batteries will live here and be accessible from the wing seat area.
This area was planked and will be glassed against oil from the engine bay. The flight batteries sit in that cone shaped area.
That's it for now. Wing seat area next.
