Just what the Dr ordered

I bought this to remove rivets in a cargo trailer I purchased so I could run additional inside illumination lights. The rivets used inside the trailer were 3/16� (a size that is listed for this product) but they were the “large head� rivets (to better hold the felt wall board in place). Unfortunately, this kit only works for “standard� AN-470 (Army/Navy spec) head universal rivets. I thought I could make them work on non-aviation rivets like the ones sold at the Big Box stores, but I made a mess of the rivet and surface, which I could have done with only a drill bit and without using this product. It’s a great concept/product if you need to drill out a standard rivet head on an airplane, but the principle at work here is that you securely place the drill guide over the rivet head to center the drill bit on the rivet head center pin. If you try this on large head rivets, the drill guide slides all over the head and ends up drilling a hole thru the side (not center) of the rivet which ultimately damages the surface under the rivet, exactly what this kit is designed to prevent. If you call the telephone number on the box label to see if they have, or can make a large head guide, you get voicemail, but no return call.
