Next job is to construct the engine-independent part of the engine/gear mount so the fuselage can be put onto its running gear. I have fabricated a jig to use for building the mount out of 30mm square * 3mm box section steel. This is sized such that the engine-mount mounting tubes (29th April 2008) which will weld into the fuselage are roughly centred in the 30mm section. As can be seen, these have been clamped to the jig which will then be removed to drill 3/8" holes. The engine-mount mounting tubes can then be bolted to the jig before they are tack welded into the fuselage. This will ensure that they are square and that the hole spacing can be exactly reproduced in the engine/gear mount itself. Additional members can then be welded to the jig to support the tubing that forms the gear mounts etc.
