Vintage Panasonic rx-5150 Boombox Head vs. Sandpaper lapping. (what could go wrong?) 🙈

So, my vintage Panasonic RX5150 had a lack of high end frequency on the right side , which was only evident when playing back recordings made on the deck. Radio and line-in was fine. I discovered that the right track on the head had a little mark or scuff on it. I had initially wanted to remove the head and lap it like a pro, but I'm not a pro and i was worried that pulling the head off may get me into more trouble in the long run. So I've done it while the head was still on the machine. This was actually not as difficult as i had expected and was quite interesting going at it for the first time. I have rambled on while doing this video but its more of a "show and tell" experience rather than an instructional video. I'm sure the experts will point out my lack of knowledge and demand i never touch vintage gear ever again. 😂 Despite my lack of fancy equipment I think it has turned out pretty good for my efforts. I may have another crack at it down the road when i have more tools and knowledge, but for the most part I'm happy with the sound playback and that's all that counts for now. Hope you enjoy the video and I'm open for criticism and/or questions.
Paper used: 2000-7000 grit. Autosol for a polish. ISO for final clean. 👍

Nice work on the video Chris! If I were doing the head in situ like this, I would 2-sided tape the abrasives to a flat stick and taper the side in order to get in closer to the guide. It's a good thing to maintain flatness, which the stick would help with. Anyway, you got your channel back so it's a win and I get to be your first thumbs up!

Thanks. Yeah i was contemplating a stick and decided against it because i wanted to get a feel of the head. This was a first run i think. I may go back at it again and try to be more accurate up against the guide. There is still a wear groove on the path next to the 2 tracks that needs to be smoothed out. But the playback seems even and im OK with it. It was more of a "lets see what happens" and it was alot of fun getting the video made. I love the boombox and dont play tapes, but its nice to know its working correctly. Thanks again for your input and advice. 👍
