Miami Boat Show, Part II- Side Vents
Among the parts that were designed to go on MTI’s new 52 for Miami were a set of 17 foot long trim pieces, and a matching set that was 1/4 scale. In much the same way the throttles were designed, a 2D drawing was done by MTI’s in-house designer and sent to me, where I cropped and scaled the picture in preparation to import into Solidworks.
This trim piece was built in two pieces, the ‘vent’ show above and the ‘bar’ that stretched almost 15 feet long. After 3 revisions, the part was finalized and the bar was sectioned into three pieces so it would fit on the CNC machine. Six 10-32 studs fastened the vent to the hull side while three studs per bar section held them secure.
The quarter scale versions for the bustle were scaled down before any of the holes and clearances were added on the full size version, as those dimensions could not be changed, then added after. The customer originally wanted these parts out of polished stainless steel for durability and appearance, but after loading the material properties into Solidworks and discovering that a vent and bar combo would weigh almost 130 lbs, the ‘OK’ to switch to aluminum was given and saved over 90 lbs.
