It was a rainy Saturday afternoon and that made it perfect for some more needle scaler work in the back shed (can't needle scale in the garage during the boy's nap time).I tackled two of the biggest parts from the crawler - the track frames. They are about 5 feet long and weigh about 250lbs. a piece. They are made of heavy steel and are perfect candidates for the needle scaler. My compressor is still waiting for its parts so the process wasn't exactly fast. I would scale an 8"x8" section at a time and then the compressor would need to catch up. During this time I took my drill with a wire brush attached and went over the section I just scaled. It was a fairly efficient and effective process.
