Hi, I see some on amazon for 20+10 shipping for 5lb 120 grit Pinhigh Reel Sharpening Compound (sold by Jesco products). Is this the recommended route?

Awesome thanks! The 120 will be good for keeping the reel sharp enough to cut paper? I also wasn't sure if I needed 120 or 180.
I used 120 for my Trucut from Jesco out of OKC. I am going to use 220 for my Baroness. @Mightyquinn is using 400 grit clover compound.

Less is more when removing steel from your reel. :thumbup:

Going to be backlapping for the first time. On a gm1600 do I run the drill on reverse when backlapping?
How many times (average) will I be able to backlap a gm1600 with 5lbs of backlapping compound?
Probably a few thousand times or more. Unless you are crazy liberal with it, I bet you will replace multiple reels before going through 5lb of lapping compound.

2 weeks into reel mowing and I already hit the tiniest of rocks that did just enough to cause one of the blades on the reel to make a clicking sound every time it goes across the bed knife. 🤬

As far as back lapping, I assume the goal is to remove the least amount of metal from the reel in order to prolong the life of the reel. Is 80 a good place to start or should I go with 120?
@Ware, is the Pinhigh the compound you use? Looks like it's the exact same one that @TulsaFan mentions in his post.

Find that high spot on the reel and correct it either by file or hammer. Then backlap. Give the bed knife a gander as well.

@MasterMech, it's such a small little part of one of the blades that makes the clicking sound...probably an 8th of an inch wide, so think the file is probably the solution. Thanks for the suggestion. My next mow is tomorrow, so I'll see about knocking out that little bit. Bed knife seemed fine, but I'll look everything over again.
I went ahead and ordered some back lapping compound but wont arrive until Friday.
