Hi Logan
I am sorry to hear that. It's very frustrating after all the effort you have put in.
I noticed you said there was a bit of construction going on in the house. Perhaps a piece of dust got into your work. Did you hear or feel anything when it happened? Was it during a wet or just at the start?
Some people add a small amount of detergent (eg dishwashing liquid) to the grinding slurry. This can help stop grit clumping together. It's important just to add a drop. Too much reduces grinding action and you have suds everywhere.
Check your mirror bevel and your tool tiles carefully. See if there is any evidence of tiles chipping. I think this unlikely but check anyway. Are the tiles getting very thin?
I have some 240 grit. Send me a PM with your address and I can arrange to get it to you. Depending on the scratch depth you may be able to get rid of it with that.
When you get back to 25 micron remember that is where scratches are most likely. So it's important to take extra care keeping your grinding area as clean as you can. Scratches during polishing are less likely.
You have done really well maintaining your motivation. Don't let this discourage you.
Rod.
