The first section of the dunk tank for alodine and aluminum prep, DX503 and DX533 respectively, was completed today. It is make from three 8′ long 2×4 studs with a 1/4″ plywood bottom. This will be lined with 4-5mil plastic on each side, then filled with about 3 gallons of material. Drain holes at this end of the tanks will funnel material back into 5 gallon sealable buckets when each cycle is done.
The length of the tank is adjustable using 6″ 2×4 pieces. This 8′ section can be used for almost all empennage parts, the exceptions being the eleven foot spars for the horizontal stabilizer. For these another section about 5′ long will be made, then bolted to the end of this tank. Two smaller tanks in this configuration will be easier to manipulate than on huge 12′ tank. The backs of both tanks can also serve as painting surfaces when they are not in use otherwise.
