Last fall I got a freebie trial copy of something called, Home Shop
Subscriptions, 800-447-7367 $27.95 US a year.
That issue had a plans and construction article on an electric scooter,
a metal spinning primer, piston and ring making for model engines,
metric equivalent drills, a sand blast cabinet plan, info on three phase
from VFD's and a story on moving a mill-drill.
It depends on which type of metalworking you're talking about. Since you
posted in the welding group I assume you're more interested in that and
except for the ones Ernie mentioned I don't know of any.
There are a few for machinists though if you're interested in that aspect of
metalworking. Home Shop Machinist and Machinist's Workshop are both
published by The Village Press. You can find more info at:
And you can probably find copies at your local Barnes & Noble bookstore.
There's also American Machinist:
and The Fabricator:
and after looking at their site I see that they also offer "Practical
Welding Today" but they're not for hobbiests so you may not qualify for a
subscription, depending on your situation. They also have eNewsletters such
as "Welding Wire" available.
