So after wigging out and buying a whack of hand tools at once rather than taking the slow decent down the slope, I have been spending the last few weeks researching and studying sharpening, and today I finally cleaned out my shop and decided to start putting what I have been learning to practice...
Well I have been reading a ton, I found I was still a bit unsure of how best to proceed so I figured I would start with the set of Narex chisels I picked up (quite reasonably priced I might add). I started with the widest one (40mm) by lapping the back. First thing I used was a 600x diamond bench stone and found that it was taking a lot longer than I thought it would. I went at it for probably a good 20/30 minutes before I finally was able to get rid of what seemed like a slight hollow right up near the cutting edge and back about 1/8th inch. I was losing faith but perseverance paid off. I moved up to a 1200x diamond after that and it took barely any work at all. I went as far as using a 4000x Norton water stone and tried the 8000x just to see how shiny it would get and I was pretty impressed.
So with the lapping of the chisel back finished, I proceeded by pulling out my new MKII Veritas Honing Guide and fiddle-farted around with it for a bit trying to figure it out. Turned out to be pretty simple and with the blade registration gauge it was pretty easy to set up so I went with the 25 degree setting. I was a little hesitant about how tight to be cranking down on the knobs but in the end just wound them as snug as my fingers would take them and it seemed to be fine.
I pulled out the 1200x diamond stone and started in. I stop every 15/20 strokes or so to observe what was happening and quickly started to notice that it seemed to be sharpening slightly uneven... Higher up the primary bevel on the left size than the right by about 1/8th inch. Not sure if it was normal or if I was messing it up, I re-examined the honing guide and noticed that one of the knobs was tightened down a fair bit further than the other knob, so I figured that might be causing the unevenness in the back of the primary bevel. After adjusting the tightness I went back it it. Shortly after everything seemed to catch up and look normal.
Then I moved up to the 4000x Norton water stone and continued my work. It didn't take long at all to get nice and smooth looking when I remembered reading about needing to lap the back again slightly to remove any wire buildup. Did that with just a few strokes and moved onto the 8000x side of the water stone. Again, it quickly came to a shiny mirror finish. A couple strokes on the back again and a couple more on the primary bevel and I was ready to turn the knob that lets you easily put on a secondary micro bevel.
Well to my dismay I realized I didn't check "that" knob when I started and found it was already on the micro bevel setting! :mad: So I cranked it over to the ACTUAL primary bevel setting and started all over... This time after finishing with the 8000x on the primary bevel and setting it to work the secondary bevel, I just continued on the 8000x side. Micro bevel done I examined my work and everything looked really great! I proceeded to test its shaving abilities on my arm and was amazed at how easily the hair just came off! :eek: I swear I heard angels playing harps!!! :D
So I spent the rest of the afternoon sharpening my chisels with a giant smile on my face. Had a mishap with the 6mm chisel while working the primary bevel where I took a bit of a gouge out of the 8000x water stone, but the 325x diamond stone cleaned it right up with a bit of effort. Also, while sharpening one of the middle sized chisels I somehow slipped and sliced a thin layer of flesh off the pad of my middle finger, which bled like a stuck pig! Funny, but I was actually proud I made it sharp enough to do that!
All in all a great day! Something most people might find less than enjoyable, but I was really impressed with what I was able to accomplish being that this is literally my first experience ever in trying to sharpen something other than a lawnmower blade or what-not on a bench grinder. Hope I didn't bore you all with my story, and please feel free to offer any advice and suggestions that might make things easier for me in the future!
