Below is another note from my EIB application on a Centurion requirement I will need to address. It appears that I made a mistake on where I placed the three rivets on the side of the abdomen.
CRL: Three rivets, approximately 5/16"(8mm) diameter, are present on the left side of the abdomen armor... equally spaced along the depth of the armor and about 10mm from the edge.
We have a challenging issue here but we have confidence that you can do it! Unfortunately, the rivets on the ab plate sit too far back from the edge and, for level 3, will need to be moved closer as seen below. The ones on the kidney appear to be farther, but we are taking into account that there is a return edge (as seen by the dotted line) right next to them. They also need to be horizontally aligned.
After moving them, the holes can be filled with ABS paste and then sanded/polished. A bit of a task, of course, but we have faith in you!
In order to fix this I am going to need to remove those rivets ans move them over to the appropriate location nearly 10 mm from where they are. I have two options to accomplish this feat. The first is to remove and replace the rivets and fill the holes using ABS paste. The other requires trimming off equal amounts of the ab plate from both sides to maintain uniformity. Now I haven't decided which route to take but wanted to try a couple things first before coming to a decision.
I decided it was probably best to do a trial run on the ABS Paste repair that would be needed to fill in the holes that will be left behind. I took out a leftover piece of ABS and drilled three like size holes. In case you are unfamiliar with the ABS paste process Here is Kman's most excellent tutorial. Next, I proceeded to fill the holes and waited for it to dry. After it was dry I moved on to sanding.
Looking at these results I am not happy with the process yet. You can see the holes are quite noticeable. I think my ABS paste was not smooth enough and air pockets allowed bits of debris to get caught in the gaps and voids making it look awful. Another thing to note is that the ABS paste fuses to all it touches so if you are not careful it gets everywhere and increases the surface area you need to sand and repair afterwards. I may be taping off the work area to help keep it clean.
Alas I have more supplies and since this was only a test I will try again to hone my ABS paste skills!
