dead trees-no
Thanks Hillbilly, anyone else wanna chime in?
I don't think a dead trees magazine would fly, although there is a lot of chainsaw action in general, it is a specialty niche and if would be hard to get distribution all over just to sell a few copies in this or that geographical area. I mean, all sorts of dead trees newspapers and magazines are struggling already as it is.
Here's the difference, chainsaws that would grace your cover cost upwards of two thousand, mud trucks on the covers of glossy magazines would be cheap at twenty thousand. There's just WAY more interest and money in motor vehicles, including what advertisers would pay.
Online, perhaps. Domain name and hosting space is cheap, knocking out a website ain't too hard especially with all the canned templates and WYSIWYG editors out there and so on.
Copy-you need writers and good pics, then do your layout every issue and tweak to size. How you gonna pay for that? You can start out a one man band for sure, but eventually you'll need outside writers and site help, and a copy editor, and quality writers will cost ya, say, half a buck and up per word (last I knew rates, at least for tech review sites that "make it")(I have done this).
Fun project, won't cost much to start, then you can make an executive decision to try and expand professionally or not, or make the jump into a dead trees magazine.
I would suggest expanding it a bit beyond chainsaws (while always having a chainsaw on the cover...) into covering related topics from PPE to processors, splitters, mills, and other assorted wood wrangling and mayhem gear-age. That expands the niche into niches and increases potential economic sustainability.
