My first mistake was not realizing how brittle aluminum threads are. I stripped the threads of the engine mount block. I used a torque wrench and installed safety goggles but still. Error #2 doesn't leave enough time to install coil and screw and now I need a new screw. After finding a new screw and learning from my two mistakes. I was able to insert two helical coils for motor mounts. The included drill worked at first. Clear the room of debris. Second, make several passes with the tap. Third, use lubricant to insert the spiral coil. Don't push, just twist and point inward. Otherwise you will skip the thread and lose. stars again and again. Visually check for missing threads and attempt to insert the screw. If it fits, no problem. You are hired. I used a pick/hook to line up the bottom and top wires. Last but not least. I used 8 of the 10 spiral coils for two setups. The first 5 rounds, the second only two attempts.
