Of all the defensive gun turret positions, arguably, the rear turret is the most critical. Consequently it was logical to provide each of its two 50 caliber machine guns with plenty of ammunition, 800 rounds per gun. Since T-Square had all of this system completely removed during one of its post war assignments, all of the OEM parts had to be restored
Auxiliary Power Unit (APU)
The assembly was completely taken apart, cleaned, straightened a bent frame, removed paint as required, cleaned and repainted with stencil work added.
Central Fire Control System
The B-29 was equipped with a unique method of operating its machine guns, called the Central Fire Control System. The fact that the plane was pressurized precluded the gunners from having physical access to the guns.
Central Fire Control System (Computer Restoration)
The computer covers were removed, and stripped of paint, internal parts were cleaned and clear plastic covers were made so the inner workings could be displayed and not touched. Also, a base frame was made for the CRC computer to be displayed on a simulated mounting in the aircraft.
Pilots Aisle Control Stand
A stand is provided in the aisle between the pilot and copilot, allowing easy each access to the controls. These switches control: Emergency Brakes, Wing Flaps, Position Light Switch, Propeller RPM switches, Turbo Boost Selector, Bomb Bay Door Switch.
Exhaust Ducts were completely corroded so advanced manufacturing was used to recreate 9 replica exhaust ducts.
Ground Power Unit (GPU)
This is a modified commercial power unit that was acquired and disassembled, glass beaded and completely painted all body and panels. The painted “star” represents the Army Air Force for the WW II time period. This unit is not a part of the airplane, but an external unit that is positioned by the front landing gear of the plane.
Gun Turret Pressure Dome
Three of the remote control gun turrets on the B-29 protrude into the pressurized crew compartments. Consequently each has to be provided with its own unpressurized circular enclosure to accommodate all of the ancillary components which make up each remote turret system.
Inverter, Electrical Box, Overflow Tank
The invertor was cleaned, sanded and touched up. Made some mounting feet and located the unit in the fuselage. The overflow tank was cleaned and painted with a new holding assembly (straps & Blocks) installed. The electrical box was cleaned, painted and mounted in its location. The vacuum line controls were disassembled, cleaned, painted and installed appropriately.
R3350 Display Engine
The engine was partially disassembled when the project started. Everything except the cylinder heads were removed from the engine. Everything was hand scrapped of oil and dirt, all the bolts were removed and polished and sealed. The parts that were disassembled were cleaned and repainted, glass beading was done to the entire engine (60 hours of work) to get the engine clean all around.
The radar assembly was completely disassembled, cleaned and repainted. The waveguides were silver plated, the dish and frame were repaired and polished the radar dish. A radar dome was later fashioned and built from scratch.
Tail Gunner compartment
Complete restoration of the entire tail section took place with the tail gunner compartment disassembled from the airplane. Restoration included the gunner seat, all gun controls, and all other aspects incorporated.
The turbocharger was completely disassembled, scraped, brushed, cleaned and reassembled. The turbocharger is part of a display engine that is shown separately from the airplane.
Radar Junction Box
All cables and connectors were removed from the box. Everything was cleaned and repainted as required.
Total Flight Surface Control Cable Replacement
The replacement of the entire flight surface control cable was a project that took more man power than usual. The importance of the flight surface control cable was more than important during flights of these airplanes.
Fuselage Skin Interior & Surface Corrosion Removal & Paint
The b-29 had a long history of corrosion due to multiple factors so the fuselage skin interior had to be restored. Along with that, surface corrosion had to be removed by a process of painting the inside and outside of the plane with corrosion prohibiting paint.
Radar Operators Position
The radar operators position is extremely unique to this B-29 in particular. Where all other B-29's had bunk beds for the crew to rest on, the volunteers of T-Square 54 built a separate station for a radar operator to work from which also included the AP Q-13 antenna. This increased the crew size from 10 to 11 members.
Oxygen System Restoration
Bob Martin was the volunteer who replaced and restored all of the different oxygen tanks and components throughout the B-29. There were multiple locations for this system because of the pressurized cabin.
The bomb racks were completely recreated using alternative manufacturing methods. Not only can these bomb racks hold the replica 500 lb. bombs, they have functionality that allows them to actually release the bombs like the OEM parts.
Control Surface Restoration
The fabric on all control surfaces were replaced and re-doped.
