I have done a little sheet metal work and have really enjoyed it (although
I'm still a novice). I have a friend who recently shut down his sign
business and sold me some of his sheet metal equipment. It is just perfect
for my home shop:

* Di Acro 24" shear
* Di Acro 24" brake
* Di Acro 6" notcher
* Berkroy 24" rolls

All of the equipment is on stands/casters. I have to clean some of it up a
little, etc. , but in general, it's in good shape.

I have a question about the shear. If I plan on primarily working with about
20 gage steel, what spacing should I put between the blades? Also, is there
any literature showing how to maintain this equipment, like how to correctly
sharpen the blades (angles, etc.), how to properly adjust the equipment,
etc.? I have printed the manuals from the DiAcro web site, but the manuals
don't have much on tool maintenance and adjustments.

Of course, with all of that equipment, I'm looking for a spot welder. The
American brand is Miller, but there are a number of Miller knock-offs coming
from China (as sold at Harbor Freight). Is the Miller welder made in
America? Is it significantly superior to the China versions? I'm just a home
hobbiest, yet I try to support American industry a much as possible. It's
just that the price difference between the two welders is about $300 and I
haven't personally held the Miller welder.

What is your opinion of the Miller vs. the Chineese spot welders?

I'm just tickled pink with my purchase and look forward to honing my skills.
Please reply to my questions and thanks.
