What grit sandpaper?

[Bud B.]

I need to clean up my nock grooves without taking too much away. My strings keep getting cut by the grooves on my LB. It's a production bow and FF compatable but I want to be cautious. I run my fingers over the grooves and feel no burs or sharp edges but the string eventually gets cut. I wax my string well also but with no luck. After about a month or so of shooting it happens. I have sanded them once but am afraid to go too far.

I was thinking 600 range or finer wet paper.

Thoughts?

As long as it's over 320 and you're careful, you're good to go I suppose

You can try 0 or 00 steel wool.

Buy a sheet of 180 grit emory cloth. Cut the sheet into quarters. Now roll one of the quarters into a tight rod.
Work over your nocks (it'll be the edges that are the issue) until all are smooth and slightly rounded.

Do the same with a rolled up 320 and put some sealer over it all and let cure.

Twist a piece of 0000 steel wool into a small rope and run it back and forth over the nocks.

That should do it!! It's very hard to change anything drastically and fast with a piece of sandpaper.

Sounds like you've done it before Charlie.    

Will give'er a try.

What Charlie said! I found at least 220 for the initial dags, limb should be immobilized to neatly work the roll. happens quickly so don't go too hard

I pretty much do it like Charlie, though I usually start with 220 grit.  Are you having trouble with both your loops, or just the bottom loop?  Getting sand and grit in the bottom loop is fairly common, and it can work on the string to fray it.

[Bud B.]

I worked on it tonight. There was a new nick in one side of the bottom nock groove. Possibly from a grain of sand or dirt.

Good call Orion.

got the poly drying on it now.

Keep us updated.

Enlightening advice - Charlie

Thank you!

A round chainsaw sharpening file works well, too.

[Bud B.]

All is well.

I went to a shoot this weekend and the nock groove repair seems to have went well. I have maybe 200-250 shots out of it since and no wear is present and I'm trying to be mindful of allowing dirt to get into the grooves again. I do think dirt was the culprit.
