thanks steve, actually we are talking the forward lower belly panel, fwd of station 23. will check with the boys at helitech, we go back a ways, no worries there. cal

not to happy with clickbond on metal. also when i say field friendly, think jungle / desert and installing/removing panels. if you trash a clickbond, no time to wait around for adhesive etc. spoke at length with our DER and other "metal men", looks like its a strip and double flush the existing...

hydtools/109: good idea,BUT, this stc is intended for field applications, so we want to use commom "bench stock" and tools. hence the good ole MS21059's also the hole in the T is 1/4 for the ketema, dont want to get any larger (ED). also, if you get a "spinner" in the field after intial...

actually the frustrating part is ketema has an V4-109 that DOES have 1.00 spacing, for some reason bell used the narrow 0.875 spaced fastner. my guess it was "in the parts bin"

109, thats exactly what we did, worked great. was just trying to reduce the "in field" workload for a metal tech doing the stc kit install. a one to one replacement would have been very easy, not that your described technique is difficult, just more time consuming frustrating that bell did not...

SAIT,no can do, will "run out" of ED on the flange edge. already tried that one. cal

sir, that is correct, we are doing an STC project which requires the removal of the ketema fastner, replace with a 1/4 anchor nut. we are trying to source a nutplate with the 0.875 rivet spacing cal

looking for: 1/4 nutplate, floating (as per MS21059) BUT with a 0.875 rivet spacing. want to do a one to one replacement for ketema V4-109. any leads would be greatly appreciated, trying to avoid having to add a nutplate strip thanks cal

sirs: after much consultation have selected to coat inside with electrodag, seems to be the accepted method. pulled first article, looks excellent

does anyone have experience using electrodag 6050 by Acheson or similar paint, if so how were the results with respect to ground plane on composite panels thanks

working on replacement carbon fibre belly panels for helicopter. original panels are made of glass / foam core. would like to lay up using copper mesh layer imbedded into carbon fibre panel. does anyone have experience with this technique as far as grounding plane is concerned
