Lapping at Randy's
I was able to arrange a meet for lapping some of my hones with RandyDance. I just never got around to it before! So; finally, today was the day. I got a fairly early start and and had a pleasant hour's drive over there. Well worth the time spent! Randy looked at the pile of rocks and said "You ready to spend the next 6 days??"
It was a bit warm today but the wind was fresh and I was comfortable while working.
We sat and chatted while I was lapping. About three and a half hours spent and 20+ hones lapped flat at DMT 220 grit.
The Geezer at work! Two fingers at the center of the hone for the last light passes will assure a flat stone.
A stack of assorted hones on the table. Fortunately they were fairly close to flat and only took about ten minutes or less each.
Mark the hones with x's and lines with a pencil. Lap a dozen figure eight strokes or less; dip the DMT in the water bucket to slosh off the slurry; dip the stone into the water bucket to slosh off the slurry. Repeat till all the marks are gone. Remark the hone with penciland repeat with zero pressure and two fingers at the center of the hone. That will tell if the hone is flat because the figure eight will tell you it is not if a part of the hone is catching on the DMT
All I have to do now is lap them at home to a finer surface texture. Randy suggests that all the hones you use be lapped to the same grit. that will allow you to have a better feel for the entire series. Meaning that each hone's surface will give the same feel during the honing.
Randy is, to say the least, a very accommodating fellow. His DMTs, his coffee, and his wonderful brain to pick for honing knowledge and useful ideas. He has been honing a lot of years!!
I had a warped DMT 320 and all the hones that I used it upon were not flat, but cupped in the center. Some of them I used the Wet sandpaper on a flat surface top improve the flatness.. I figured that it was time to really get them flat!
No, I do not have HAD!! I like to experiment!
Squeaky Pen / magic marker does stain the Shaptons!! Even though the surface is flat the marks soaked into the surface. It worked well on the other hones but a pencil is better for me. I tried the magic marker suggestion that was posted to mark the Xs and lines.
