Thanks for posting this to the forum for others to use. It would be nice if you would post the actual instructions here (to make it searchable and persistent) rather than a link to your site. You could also post the PDF as an attachment, as a second-best option.
My main objection to what you wrote above is that you announced you were selling information instead of... or prior to... providing it here, for free, with no strings, to the community. I still find it distasteful that you are seeking to profit off of this; nobody else on any car forum I've been on has ever
done that, and I believe it is fundamentally antithetical to what these forums are about.
This is principally because the forums are about enthusiasts helping other enthusiasts simply for the love of the cars
. The profit motive wrecks that. For example,
wrote a great how-to on repairing headlights. He posted it on the forum
for all to see and comment. It was detailed, illustrated, and HUGELY helpful. He didn't look to profit from it -- all the benefits went to the rest of us here on the forum. And that's what these forums are all about
(You may respond that what you were asking to be paid for is the printing of a fair copy. I don't find that credible, frankly, given your initial posts on this thread.)
I think it's important to note that posting how-tos on the forum, publicly and for free, also has the effect of making the how-tos better. Other posters can comment, like agentdr8 did above, in ways that improve the overall product. With a PDF, especially one hosted offsite, there's no way to layer comments or improvements. Post the text here in its entirety, on the forum so it is plain and searchable, and we can do that.
My secondary objection to your project is that I don't believe that you were or are inclined to give credit to sources here that you've drawn on. You have avoided, both in your comments above and in the document itself, simply acknowledging that someone else here originated the only ideas that are different in your method vs the shop manual. I'm not looking for credit, still less for my name to be out there. But it sure looks to me like you're the kind of person that just can't say a simple "thanks" when someone gives you concrete help, and that bugs me. My problem, I guess, not yours. And like I said, this is a secondary objection -- whereas trying to profit off of selling assistance to forum members, however you pitch it, hits at the heart of the little community we have here.
