I saw that somewhere else but I didn't get it. That cleared it up. Now I got to go steal my wife's tweazer and try it out. She's always losing things so I can play dumb. Ha Ha

Hole Finder A hole finder is a tool used to transfer existing holes in aircraft structures or skin to replacement skin or patches. See figure 13-5. The tool has two leaves parallel to each other and fastened together at one end. The bottom leaf of the hole finder has a teat installed near the end of the leaf that is aligned with a bushing on the top leaf. The desired hole to be transferred is located by fitting the teat on the bottom leaf of the hole finder into the existing rivet hole. The hole in the new part is made by drilling through the bushing on the top leaf. If the hole finder is properly made, holes drilled in this manner will be perfectly aligned. A separate duplicator must be provided for each diameter of rivet to be used.

Just whiped up this tool tonight and it worked great! Total cost of the tool with the bag of screws was just under $1.60.

I made one of these yesterday and used it to do the front trunion holes on my AMD-65... This tool was simply awsome!!! I managed to find a set of tweezers with a wide and flat "pinch" surface... that was the hardest part of making these....

Then I took a piece of scrap steel that I had that was about the diameter of the tweezers and placed it between the two tongs of the tweezer for spacing and drilled a hole through the on the trill press. I used a #29 drill but as I had the 8-32 tap and plenty of 8-32 screws.

Next I checked the tweezers and when they wre pinched closed the holes were perectly aligned so I pinched the tweezers into the vise and tapped the holes 8-32 and screwed in a 8-32 x 3/8 button head screw....

I had all six of my front trunion holes center punched on my receiver in less than a minute... this is THE WAY to do front trunion holes when you have the barrel pulled.

Now I need to see how this can be done with the rear trunion holds

I have pics and I will try to post a link when I get time to get my pics cut down plus I have server space issues as I have about 700MB of photos on my current build so far... I need to get rid of some and cut them down but I want to keep building when I get a few free hours too...
