OK, this is not being grasped as I intended. Alan Peters has nothing to do with trolling. The fact that he used mostly a no 7 is well known.
The trolling comes from others on knots and such places using Alan Peters as a hammer (Alan had nothing do with any of it). when you're new to forums, you ask a question in honesty and someone bombards you with insults and uses a third person's work, you don't recognize the pattern quite yet. I learned it over time. The folks doing the trolling rarely had the bravery to show their own work (in fact, I'm not sure that they ever did) as they probably couldn't find paying work that wouldn't compromise their ability to work (e.g., if you're bolting together farm tables or simple stuff and not making federal period furniture, you lose leverage).
In your case, David, one of those trolls chased you off of woodnet. You may not recall it, but I learned to sharpen from your video, so I was delighted that you dropped in to woodnet. You were there for perhaps a day or two until one of the trolls had harassed you with the "show me your portfolio" garbage (without showing anything of their own) and you said "OK, that's enough of that" (not figuratively, that's literally what you said) and never returned.
Same thing happened to George Wilson when he retired and showed up on sawmill creek at the time. I didn't know who George was and thought he was a bit direct (but learned since that he's very thoughtful and rather than hassle people who never seem to progress, he leaves them alone). Alan and Richard's (slainte) work were used as an attempt at a hammer to harrass George. Except George's portfolio is full of stuff that perhaps nobody else could make, so not much sticks.
re the 6 irons that alan sharpened -I've never had any issue with irons made in the 40s or 50s ,but round top irons made in the 70s are not great. I don't know Alan's story as well as disciples would, and it makes me a little grossed out that I think many tried to associate themselves with him just to use his name recognition, but I'd gather that the desire to have a large number of irons like that was probably more geared toward working on the clock and not sharpening. Whether it would've been 6 old ones or 3 new ones, it doesn't really matter too much. The japanese did the same thing (maybe that's where Alan learned it). It was considered to be rude and presumptuous to be performing any tool care on a customer's site on the clock.
FWIW, just about everything I chanced into that increased productivity (and turns out to be more of the historical standard for planing than the current methods), I learned because I was trying to stretch out iron life. All the way down to joining boards without using a square (that are not matched planes) and planing edges hollow without stop shavings. These are great things for a hobbyist to learn, but become back burner once someone moves up the ladder and uses machine prepped wood for the most part and gets into marquetry, design and carving .
I do not believe any of the great makers were ever trolls - they wouldn't have had time for it, and if that was their temperament, they never would've been great. I'm sure some could've been impatient with apprentices or legitimate students, but that's a far different thing than berating someone who comes in the shop door and asks their first question.
