Okay,back to the build.
Yesterday, in an all fired rush to prepare the scruffy looking, dust covered heap for the Midhurst Modellers Show this coming weekend (27th Feb, The Grange Centre, Midhurst, Darkest Southern England.) we tidied, vacuumed and sanded.
1) Pumps fitted, these were bolted in the case of the 'pump out' pump, and siliconed in in the case of the 'pump in' pump. The 'in' pump is flush with the bottom of the hull and fitted into a 2" dia hole. The 'out' pump is raised off the tank bottom by about 3mm and secured with stainless M4 machine screws.
These pumps are Whale Industries marine bilge pumps and will pump up to 50 litres a minute, if you ever want a firefighting monitor pump, these are the kiddies
2) The rudder is next, this is loosely based on the Schilling Rudder concept, with a wedge at the trailing edge to deflect water sideways similar to a Becker Rudder, but without any moving parts. This started life as a commercially available rudder which then had a copper blade soldered to it using Plumbers Solder, hammered to shape, and filled with Glassfibre Repair Paste before being trimmed down with various sanding implements
3) Push Bars, these are for the two Destroyers to locate into, as they come along side for the last part of our display. The bar is 4mm Stainless Steel, the tubes are redundant 8mm dia propshaft outers and are drilled through the model BELOW the lower hull, but through 3/4" of timber sides hanging below the flat bottom.
These bars are removable for transport and for playing down the lake on a sunday. Only one has been fashioned so far.
The Destroyers have an aproximate beam of 5 1/2" and will have a pin protruding below their hulls at the centreline. The 'vee' in the rod has been placed at 3 1/2" from the hull side to 'stand off' the destroyers slightly from Ohios sides, allowing them a little manouvering ability and to protect their much nicer detail work from damage....Thats the plan anyway
Anyway, see some of you at Midhurst
