I’m finally spending some time on the MC850 again. My son’s stroke was disabling but could have been worse. I won’t discuss that anymore because that’s not what this blog is about, however, my work will be at a slower pace due to having less available time.<\/p>\n

I have been worried about the thick, hard undercoating that I have to remove. I wasn’t happy with the chisel in the air hammer approach so I decided to experiment. A number of Youtube videos talked up the needle scaler as a great tool so I bought one from Harbor Freight. I made a video of my testing and put it on Youtube but I later found the videos had been removed. Therefore, I have updated this post with a few relevant clips shown here:<\/p>\n

At first, I was happy with the needle scaler and said so in the video. Today, after further examination, I’m not so happy. The first photo to the right shows the area I cleaned with the needle scaler after cleaning it with a wire brush to examine the metal surface — pretty dinged up. The second photo shows a closeup of the recessed area, and dings are evident there also. Oh well, maybe I’ll use the air hammer approach on flat surfaces, the needle scaler on large contoured or recessed areas, and the stringer bead wheel on small areas.<\/p>\n

Any suggestions are welcome. I just put my findings out her and on Youtube so you can draw your own conclusions from the test.<\/p>\n","protected":false},"excerpt":{"rendered":"
