All your videos have been super interesting to someone who recently purchased a Yamaha G5 made in Japan in 1967. It needs some finish work for sure so any videos you make prepping and spraying lacquer would be helpful. Please consider doing voice overs. Your insight is very valuable. Thanks!

Hey congrats on the new purchase! Thank you for the comment and the input!

Great Video. I am looking into getting into repair work. I know polyester can be in very short demand, along with several other types of finish. It seems the trade is not being passed down. I love the meticulousness of the craft. Any and all information helps just to understand how different chemicals and bonding agents work with one another.

Good informative video….well done! Thanks.

Watching the timelapse with your narration in the audio is quite therapeutic.

[@basdevries3707]

Interesting to watch. How long dit the whole job take you?

[@JacobEmch91]

Thanks! A couple days.

What sander and polisher are you using? Thank you. Great work

[@JacobEmch91]

Mirka and Makita

[@brandonevans7438]

What type of buffer and pad is that? What polish do you use with it? Seems like a solid vs a liquid?

[@JacobEmch91]

Hi there, it’s 4 half inch thick 10 inch canton flannel wheels. Gw16 compound. Go to alliedpiano.com for more info.

Great job Jacob what chemical in the tin did you use for wiping after sanding…and what was the buffing soap you used with the big buffing wheel. Many thanks

[@JacobEmch91]

At the very beginning of the video? Acetone. While wet sanding with the higher grits, soapy water. Menzerna gw16 compound.

For what its worth, I prefer the narration. Just saying...

[@gw1560]

You are so amazing. This is more than impressive,

[@pianopricepoint1560]

Question for you: I just obtained a flap wheel and it has a myriad of threads flying out of it. Will that eventually dissipate with use?

[@JacobEmch91]

Hi there! That’s normal. Get a buffing rake and either stand on it or clamp it firmly to a table. You’ll need to clean the wheel with the rake periodically.
