35 - PIN, PINS PIPE PIPE, INSULATOR Wood Inspect for defects, such as checks, corona burns, broken insulator threads, etc, Sound pins may be re-used. Steel Clean, paint rusted spots with rust preventive paint, such as 11 Sub ox" or regalvanize if necessary. Straighten insulator threads to obtain good insulator fit (lead heads may be re-cast). Long shank pins for wood crossarms may be converted to short shanks for steel mounting by cutting off, turning down, and re-threading the shank. INSULATOR RIDGE Insulator ridge pins may be made up from salvaged angle iron static bayonets and studs may be made from reclaimed 3/4" bolts, studs and truss pin bolts. Pipe in good condition may be saved in all lengths and sizes. Short pieces formerly disposed of as scrap may now be saved and used to make nipples, or issued vhere short sections are required. Many scraps of pipe may be velded, or threaded and coupled, into new non-standard lengths. See Appendix HAn Pig. 24 CAST IRON SOIL Pieces of cast iron soil pipe may be welded together and used for cable conduit. Prevention of beads on inside of the pipe which might injure the cable can be accomplished by slipping the pipe over a snug-fitting rotating mandrel during the yielding operation.
