The lower panel of the mast tube is 14mm outside diametre high modulus tube. A piece of 16mm tube forms the basis of the horizontal element of the joint. It is glued in place together with pieces of 14mm sleeve that form the first telescopic taper element of the main boom and jib yard. The...Read More

This is one solution for M class booms. A bit labour intensive but light and stiff. The balsa core in the elbow could be replaced with foam though arguably using balsa offers toughness. There is possibly a windage advantage in round booms, and our experience shows this to outweigh the downwind projected area and end-plate...Read More

Ray is making progress with the rigs for the Octave prototype. The design uses a simple method for cantilevering the cranes from the upper mast tubes. After drilling, fitting, and bonding, carbon tow is used to prevent splitting. The mastheads are filled with low density filler mainly to keep water out. This system eliminates all fittings...Read More

Chris Lawrence has had the first plug milled for BlackIce. Moulds and a prototype will follow…Read More

A view of design detailing for an open wheeler tub. The client was kind enough to allow us to share this view of the main carbon safety cell prior to fine detailing. Very interesting to apply our knowledge and tools to different worlds. While we are on cars… Here is a view of a prototype...Read More

A prototype airframe ready for flight testing. We rarely get to post about this UAV project due to confidentiality concerns. But this particular model is now out in the open, so here goes… By way of background, it was commissioned by a local defence contractor working with Sinagapore Aerospace, BAE Systems, and Sydney University. We...Read More

CAD drafting and optimisation work. These images of a shortlisted (but not final) design have been cleared for release. Most aspects of the project remain classified.Read More

Some images from a study commissioned by a Sydney owner for a harbour racer/day boat. The concept is for a very clean, simple boat, easily handled by a small crew. Cockpit size is prioritised over internal volume and accommodation. A deep fixed keel can be retracted to reduce draught. The hull form is of moderate...Read More
