Hi folks,
I'm about to start some welding on my car over the next couple of weekends.
The project mostly involves grafting on some new fender flares and filling
some trim holes (didn't like the chrome strips.....).
I know I need to grind the outer surface (the area I'll be facing) down to
clean bare metal before I start. Do I need to do the same with the inner
portion? I know there's at least paint, undercoating, and dirt on the backside;
does this all need to come off too before welding?
Also, I'm going to be shopping for a new grinder this weekend; most likely
a Makita or DeWalt (I'll be trying to pick up the highest amperage model
I can). There are 4" and 4.5" versions of what appear to be the same grinder;
the only difference I can really see is the arbor size, the price, and that
.5". Is is worth paying 50% more for the bigger version. I plan to do
grinding with this (duh...), but would also like to be able to put on a
cut-off wheel (like for the air die grinders), and maybe a wire cup brush.
Can I find these types of accessories for either one? (what arbor size do
they use)?
Thanks for any tips/advice,
Mike
