    Shelf life of two-part methacrylate

    MintJulep, you make an excellent point. This adhesive is unique to this application and has been put in MRB and can not be issued without a formal deviation. The deviation is time specific not to exceed 30 days. I share your concern about the "slippery slope". Thank you.

    Gauge callout on drawing

    Thanks all. So it seems the .400 and 2.900 values are somewhat arbitrary and the .400 is just what 2.900 yields when trigged out. Have I got it? See attached. http://files.engineering.com/getfile.aspx?folder=5888d124-91d1-4820-a5a1-1ad30a9a77af&file=Eng-tips_sketch.doc

    Gauge callout on drawing

    I have a drawing with GAUGE attached to two dimensions. Have not seen this callout before and am unsure what it means. The attached sketch is representative of the drawing. If you can shed some light, I'd appreciate it.
