Okay, this may be a bit silly to some but I am going to ask anyways.
How do you grind and hone the 45* bevel on a cabinet scraper?
I just got my 80M in the mail last night and gave it a quick once over. It needed one end of it squared back up, so I just took a bastard file to it. Since I did this w/o a fixture the edge is square, but the bevel is not 100% consistent across the length. Normally with a plane iron I would just toss it in my cheap bevel guide and happily set the bevel via scary sharp or set it up on my low speed grinder. In the case of the no.80 neither of these options will work (okay, technically I could grind it with the wheel spinning away and it would work).
I understand that on this cabinet scraper the thing will work with anything from 45-90 on the back bevel. I am more interested in how you hold the blade consistently than the exact angle you grind. Does it fit in an MKII or other jig? Do you make your own? Do you just wing it freehand?
How do you do it?
I flattened the face of the blade with sandpaper 100-600g and raised a burr from the bevel with a course oilstone. Then I knocked that burr off with the 600g. Even with this crude prep the scraper worked fairly well and was able to pull thin shavings. I still need to flatten the sole for better consistency, but I imagine this is a tool I will be reaching for more often than I had thought. Any tips are appreciated on tuning.

Unfortunately some of the other go-to reference articles have fallen into disrepair. I have found several people pointing to sites on the use and preparation of scrapers that are no longer there. Any new links?
