I have a number of very satisfying restoration projects going on right now. Here’s one: I was given several old power tools, because the owner figured I would restore them. They were in his family. They are well made, and I was glad to get them. I actually have them already, but mine are problematic; these will be a nice replacement. Here’s a picture of them before I took them off the trailer. 
What you’re seeing are two benches. The closer one is wood, and has a motor and grinder mounted on it. The second one is steel, it has a jointer on the closer end; and a table saw on the end closest to the gold van. The lower shelf has a large electric motor.
I removed it from the trailer, and started working on the jointer first. It’s used like a planer, except that it makes the edges of boards true, so that they can be fitted together nicely. The tool has been out in a barn for awhile, and I encountered problems right away. Last weekend,I was using spray lubricant generously, but several parts would not become free from the rust that held them. These parts weren’t easy to get to, and would have caused some problems if I hadn’t got them resolved today.
Here’s what was difficult: All these tools and parts are setting on half of the jointer top, This half raises and lowers at an angle, The places where it contacted the jointer body were rusted together. After setting a week with penetrating oil, the parts became free, and will now move as needed. I’ve never had good results using the oil this way, until today.
Parts A is one of three cutting blades. They are held into slot F by pieces like B. Obviously, there are 12 little bolts that need to be loosened in order to get the blades out. Unfortunately, 10 cooperated, 2 did not. These two seemed to have a smaller head, and I rounded the corners on one bolt head trying to loosen it. That’s bad news because they’re all positioned down in slot F, and only an open end wrench will get in there. The 10 came out with a 5/16ths wrench. I even made a smaller wrench from an unused 7mm wrench. I made it so tight that it had to be put on with a hammer. It still didn’t work. At last, I tried using this odd chisel like tool, C. I put it on a corner of the bolt head, and tapped on it with the hammer, in a counter clockwise direction. It worked, and the threat of using harsher methods was gone. Not only that, but I can go to the next steps, which puts me close to using this tool.
That was a very good start to my Saturday. It got better. My son helped me go get an older air compressor, which will be a benefit around here when it’s restored. After a few more projects, I had one of the best Saturdays I recall in quite a while. Imagine how the Lord feels when a person repents, and makes progress in learning and living more for Him. Below is a well known Psalm, sometimes used at funerals; but consider it in the context above.
A Psalm of David. The LORD is my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters. He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake. Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever.
