I have a joint location that is not on primary structure, but in an equipment bay.
The joint has been double drilled and once it’s reworked to clean/round, will have a diameter of .3125.
This stackup is multi-layered (0.040~.063 thk); angle, web, channel and another angle. All totaled, the thickness is just under 0.25 inches. Given that its four layers, I’m not going to install individual pieces of freeze plugs (bushings). Instead, I’d like to fabricate a flanged spacer, to be pressed fit into this joint.
My thought is that it would act like a large bolt (while calling out similar drawing’s hole tolerance), with the center drilled to install the drawing’s required fastener (3/16th hi-lok). I don’t have the actual loads, but trying to justify this as a suitable method. What rationale could I use while staying within an equivalent strength's guidelines.
Thanks in advance for your suggestions/ideas.
