Well done Phrank! And nothing like starting at the top - Go Big or Go Home...
I'm still struck giddy some times when it all comes together - if you want to hone your own it can be very rewarding (and frustrating) - "walk away" is an important pointer.
The best advice - I think it was Glenn/Gssixgun - was to learn how to maintain a known shaver. When you start with an Ebay razor you may be "restoring" and that is a differnt skill set from "honing"
So if you have a 4/8 and something to lap it with (DMT is great because you can use it on non-razor things - clean up the Mother In Laws kitchen knives and you will be Golden) you can use that 8K like a Barbers Hone.
Once the HAD kicked in and I had a 12k Nan, that became my "Barbers Hone" and for most of my razors that is what I use.
I tried the 4/8/12 Zowada method on three razors and the results left me doing the Razor dance of Joy...
Keep some kind of notes...
A 30x loupe with light is your friend...
And I still have a few set aside to send to a Pro...
Like shaving - it's a fine motor skill that gets better.
Keep your elbow up...
