About this file
This is a detailed engineering drawing showing specifications for rotor cooling fin assemblies, including top and bottom cooling fins, blade components, and locking tabs. The drawing provides precise measurements and specifications for fabricating MU 12 rotor cooling fins for The Dalles Dam.
The drawing includes multiple views and detailed dimensions for each component, with scales of 1/4 and 1/2 indicated. Key specifications include material requirements for ASL plate 3/16" thickness and notes about bending steel with 1" inside radius. The drawing shows both top and bottom cooling fin assemblies with 42° bend angles, #11 (.191) hole specifications, and detailed measurements for positioning of components. The parts list indicates quantities needed for assemblies including fins, blades, locking tabs, rivets, and washers. Notes specify that the material must be microfibrax D or equivalent non-woven glass fabric combined with elastomer (Mil-C-24769/1, Type GME), highlighting the specialized nature of the components.

NOTES:
1. MATERIAL A36 PLATE 3/16" THICKNESS
2. MATERIAL: NP509(NEMA G-9) consists of woven glass fabric combined with a melamine resin system. NP509 complies with the requirements of MIL-I-24768/1, Type GME, and MIL-I-24768/8, Type GMG
3. BEND STEEL WITH 1" INSIDE RADIUS TO THE DEGREE AND TOLERANCE AS SHOWN
4. PAINT ENTIRE ASSEMBLY WITH GLYPTAL 1201 LIGHT BLUE
5. RIVET HEADS AND WASHERS ON NONFERROUS SIDE AS SHOWN
6. TOP AND BOTTOM ARE DIFFERENT (128 ASSEMBLIES TOP AND 128 ASSEMBLIES BOTTOM)
7. IF BURNING THE GEOMETRY ON A CNC, THE ENTRY AND EXIT FOR THE HOLE
ADJACENT TO THE BEND WILL REQUIRE A 6 O'CLOCK ENTRY AND EXIT.
8. THE HOLE ADJACENT TO THE BEND LINE SHALL BE FLAT WITHIN 1/32"
AT THE 12 O'CLOCK POSITION, POST FORMING OF THE MATERIAL.
