Hi all I am looking at getting an extra course 180 grit lap for power hone to hog out blanks is there anyone use these and if so your comments would be helpful and welcome.

not sure of the 180. all mine are 6"disks. the bad boy in the bunch is a 150. useful only for gross configuration of gravers. it's fast, but must be used with care as it removes graver material fairly fast. my first time with the 150 created a real mess.i no longer use the power hone. i have found favor with the disks mounted in a drillpress. i got mine rather cheaply on ebay. there's quite a variety of grits available.
i like them for the greater surface area and peripheral speed. for lube, i use common mineral oil. easily cleaned with a tooth brush and a spritz of wd40.
