GREENY’S 830XCAB BUILD
Post #3 following the build progress of one of our 830XCAB kits in Hobart, Tasmania:
At this stage the main bottom structure is all in place, tacked only. Aluminium shrinks due to heat on welding, and controlling that by careful design-for-build mentality is critical. The general concept is to tack as much structure as possible together to form a stiff box, that will hold its shape when the proper welding commences. Everything’s in a defined build sequence, set out in our drawings and instructions.
A couple of things to highlight from the photos:
- The amount of detail that goes into a kit design, these are just a handful of snapshots of parts of the hull bottom
- Aluminium’s a fantastic boatbuilding material, but can be prone to fatigue cracking if not correctly designed. Note the “soft” details everywhere, smooth transitions that make for smooth load paths, and prevent cracking long term. Tiny details like stringer cutouts matter.
- Alignment marks that simply the whole process.
