| Anyone have a link for installing a MICH plate with screw to a MICH helmet. Seems pretty straightforward but before I drill and ruin an expensive helmet, I thought I'd better check... |

If you have the strap that goes with the mounting plate, it can be used to trial fit everything up to help make sure you get the hole in the right place. Use a very sharp drill bit, and be patient drilling through the aramid. Taping up the backside should minimize the effects of breaking through. |
+1 and to add, SLOW speed/heavy feed technique on the drilling. I start with a pilot hole first as well. Hope this helps. Vic |

+1 on all the above. Make sure you have the mount perfectly vertically spaced. Then with a fine tip felt tip pen, make a vertical mark through the mount hole. Then you will have a good reference to drill your hole. I do a lot of drilling through kevlar flight helmets and will tell you that like the others have said, guy a brand new drill bit. Don't get to fast, but don't get to slow either. Wht you have to watch for is the blade grabbing a kevlar thread and starting to pull it free. As victor said, start a small pilot hole first then a mid sized hole, then the size you need, hence three drill bits. Good luck. |
Even better! |
| That is how the instructions were given to put a Maxillofacial Shield on our HGU-56 helmets. It is pretty easy for a dull bit to grab a thread and literally rip it out of the helmet. I'm thinking the Kevlar helmets use a epoxy between the kevlar threads and wouldn't do that, but I'm thinking it could make a helluva mess around the hole. |
