VOL. I BOOK 5 CHAPTERIv SECTION 1% At Station 805, two 60-inch searchlights were installed by Holmes & Narver at elevation 112.5!’ of the Site Elmer photo tower. One Baird spectrograph was placed at the 100-foot level, followed by another a short while later. From 3/16-inch steel plate, a Holmes & Narver welder cut a shelf and welded it to the railing at 112.5' elevation. Men and equipment were furnished to shift the spectrograph to final position, and a carpenter with tools was made available to cut instrumentation holes through the side of Station 805. Following K-Day, the spectrographs and spotlights were removed from the station and taken to the AEC Warehouse for crating and shipping. The frame shelter for Station 806 on the Mack coral head was temporarily erected on Site Elmer, then dismantled and re-assembled on the coral head. A davit capable of bearing a 400-lb. load was fabricated and placed in use at Station 810.03 on Site Noah. From 20 October to M -5 Day a laborer was provided Project 8.1 to assist in installing instruments in the Station 810 series. Labor and equipment were required to clear the line of sight to Station 1 from Stations 810.05 and 810.07. Prior to K-Day, Station 810.09 was removed and relocated, and Station 810.10 was tilted. Additional support provided to Project 8.1 included splicing of five slings of varying lengths from 1/2-inch wire rope; providing an LCM to transport a 1-3/4 ton truck to Sites Tilda and Janet and return to Site Elmer; installing a hasp on the door of Room ''J'' in Bldg. 211 and furnishing of a padlock and keys; furnishing and installation of one piece of 1/2-inch plywood 3'-0" x 7'-0" in Room "J"; checking storage batteries at various times for electrolyte level and discharged cells, and the furnishing of two laborers for one day to aid in the delivery of equipment to the project's offices. Holmes & Narver also furnished material and labor to cut out ten 30-3/4-inch-diameter circles from 1/2-inch plywood and delivered the circles to Project 8.1 personnel on Site Gene. One rigger was furnished at Site Gene to perform services for this project until evacuation, LCMs and crews were furnished for night calibration of scientific equipment. On 26 October an LCU with crew, transported four NRLK trailers from Site Gene to Site Elmer. An electrical check was run ona timber unit and converter assembly to correct an excessive voltage drop when lead was placed on the equipment. A sheet metal tube was fabricated, 14 inches in diameter and 12 inches long, also two sheet metal discs 14 inches in diameter and each having a 6-inch aperture in its upper half.
