Dang it!!!!!

Hi y’all. Been a bit since I posted anything on the Jeep. Did a test run on the motor and shaft, sounded a bit “buzzy” at mid throttle but smoother out in low and max power. Then, I installed the prop, and tested again..this time, I thought she was going to vibrate to pieces, and the amps went wayyy up. I tried reinstalling the motor, checked my coupling motor and shaft alignment, all looked good. Then, when I had it a low throttle, barely “ticking over”, I noticed the prop was a little..wobbly. On close inspection I found that the shaft was slightly bent right where the threaded portion ended, causing the aft end of the prop to rotate out of round by about 2mm. Now, I don’t have the tools to really straighten a shaft this size and get it dead on, so I looked the shaft over, found the bend, put it in my vise and gently bent it in the opposite direction. I got lucky as subsequent tests showed I was on the right track. Much quieter, very little vibration and the amp draw diminished dramatically. But, it’s still not right. Usable, but not dead straight. I found a vendor on eBay with 3mm that are threaded, so I’m waiting for that to arrive. Once it’s here, I’ll cut it to size and retest. I did get the upper railing made up and installed, did a combo of soldering the easy joints and ca’d the rest. I also got the towing bar and gear built, painted and installed.
