Yesterday was a whirlwind of activity so I didn't get a chance to post. I am now back home and recovering comfortably. Yesterday went a little something like this:
First thing I did was jump on the grinder and take the bevels from rough grind down to 800 grit cork. I was tired on the last day and I could really tell because I was having trouble keeping my eyes focused as I worked down through the grits. If I were at home I probably wouldn't have tried to grind but, I had no choice if I wanted to finish this knife. I should mention that most of the grinding I did at Johnny's was on a TW-90. It's a nice machine. I'm curious if I will hate my GIB when I get back on it next week. Here's the blade after the cork belt.

Since I was going to have to sit around and wait for the 1-hour epoxy to set up, time was valuable. I skipped pictures of all the work getting to glue-up. What I did prior to getting to glue-up was hand finish the blade to a even 600 grit. Next the bolsters pin holes were tapered and they were installed and peened with nickel silver pins. The red linen micarta was cut out, squared and flattened. We added some red paint to the epoxy and attached the handles with brass pins. The 1-hour epoxy took right about two hours to set up enough to go back to work.

After the epoxy set, the handle material got roughed to the profile of the tang.

Johnny's workflow is to then take the profile all the way down to a nice 400 grit finish with everything square to the blade.

This is rough shaped on the 8" and 6" wheel with a 36 grit belt. Actually starting to look like something.

Johnny showing me how to use the rotary platen to refine the shape of the handle.

After working down to 400 grit on the rotary platen and a 1" slackbelt, it looks like this.

Time was really running out on the day so I didn't take any more pictures of the process. All that was left was a little hand work with some 400 grit to get rid of any tiny ridges or bumps. After that was the buffers; fine Scotch-Brite wheel first followed by a loose wheel and then a buff wheel. A quick wipe down with WD-40 and it was finished.

A big thank you to Johnny! I had a great time and learned so much.
