I am looking for some input on a project that I just took on for my son. He has an older Mossberg 500 that his mother gave him when he was 15 years old; he is now 54. I am trying to refurbish this gun as it has a lot of sentimental value to him and I'd like to bring it back as close to original as possible. I have the wood just about stripped of the old finish using Citrastrip and a scraper. The problem I am having is trying to figure out how to get the original finish out of the "pressed" checkering?? Right now the pressed checkering is full of Citrastrip and....old finish. I have tried a sharp pointed carving blade, a scriber and 120lbs of compressed air, but...it isn't moving. Any ideas would be helpful. I am not certain if this is the correct forum to be posting in, however I am at a loss with this stock right now!!!! I've read where one can use a checkering tool (like 18 line tool that I have) to re-cut the pressed checkering, however I would prefer to keep the shotgun as close to original as possible. This shotgun means a lot to him and I would like to get it right if possible. Any suggestions would be appreciated.
***After reading some of the replies I would like to add that I pretty much have all of the finish on this shotgun off. I used the Citristrip and some hand scrapers that I will use to get the finish off, then usually will DA the rest of the remaining finish. This issue is the finish that is left inside of the pressed checkering. I finally got some photos up. One of the photos is of the tools that I have already used without success. I was willing to pick each checkering pocket out with the carving blade and the sharp awl, but they didn't work either. This wood is pallet wood, the shotgun is not a Citori or a Perazzi, but it is much more priceless.
