Subject:	Erratum:  Wire Mount Documentation and List of Drawings

Dear iTPC Experts, 

Bob Scheetz noted that a pair of drawings I listed, previously, are obsolete.    (24A397, 24A398 and 
24A399 are obsolete).   Enclosed is an updated list with the most up-to-date drawing numbers that I am 
aware of.  Also included are a list of small parts require to complete the fabrication of the inner sector 
strongback.  If you see errors or discrepancies or missing parts, please shout loudly.  We are trying to 
determine precisely which drawings are required for fabrication and which not.  Thanks.

Cheers,
Jim

Wire Mount Drawings 

24A395 - Anode Wire Mount, Inner, Right 
24A396 - Anode Wire Mount, Inner, Left 
24A400 - Gated Grid Wire Mount, Right 
24A401 - Gated Grid Wire Mount, Left 
24A402 - Gated Grid Wire Mount Extrusion 
24A403 - Inner Sector Wire Mount Insulating Board(s) 
24A450 - Gated Grid Wire Mount Board (MISSING from ARCHIVE!!) 
24A459 - Shield Wire Mount, Right, G10   
24A496 - Shield Wire Mount, Left, G10 

Assembly Drawings 

24A500 - STAR Inner Sector Wire Mount Detail with Electronics installed 
24A457 - Gated Grid Wire Mount Assembly, Right 
24A458 - Gated Grid Wire Mount Assembly, Left 

Small Parts Drawings 

24A021 - Outer/Inner Sector Strongback Sleeve (2 of -1, 3 of -2 per sector) 
24A054 - Outer/Inner Wire Mount Pin, Tapered (36 per sector?) 
24A424 - Wire Mount Thread Support, 10-32  (36 per sector) 
                   Keensert, thread locking, KNL 1032  
24A425 - Wire Mount Thread Support, 1/4-20  (3 per sector) 
                   Keensert, heavy duty, non-locking, KNL 420 

Outer Sector Drawings that might be useful for reference:  

24A030 - Wire Mount Concept, Assembly view (Outer Sector) 
24A031 - Wire Mount Concept, Exploded view (Outer Sector) 
24A454 - Wire Mount Pinning Assembly (Outer Sector) 

Note that the Inner and Outer Wire Mount concepts are not the same and so you should always look for 
an inner sector drawing as the final
reference.   Compare inner and outer conceptual plans 24A500 .vs. 24A030.

Cheers,
Jim
