ok so you guys convinced me that the silver solder is not going to work in
this application. what about this welder?

does mig welding produce the bright hot flash that arc welding does? bottom
line do I need a welding hood or goggles?

I just have a torch to use maybe map gas is better then propane

MAPP gas burns hotter than propane. So by that metric, it is "better" than
propane.

can I braze with just a torch and can I braze in my basement?

Yes, a good pressure-regulated swirl-flame torch can be used for brazing
as long as the heat output is sufficient for the job (depending on the
size and material of the parts being brazed, and the brazing rod being
used). Whether it's possible or feasible for your job, I don't know.

As for brazing in your basement, I'd be cautious. One, you'd need to be
sure there is plenty of ventalation. Second, you'd need to make sure there
are no sources for flammable vapors (like old paints or other chemicals).
Realize that many flammable vapors are heavier than air and will
accumulate in low places (like basement floors). If it were me, I'd do the
work in a more open area and then move the table into the basement.


I checked with the steel place and they said the 1" stock is an 1/8"
thick not sure what gauge that is.

That's very thick metal for brazing with a simple air-burning torch, even
using MAPP. I suspect you'd need an oxy-acetalene rig for brazing tubing
that thick. MIG welding would be far easier and stronger.


im making a drum sander so I would guess the
total weight will be 75 lbs. maybe lighter.
basically its going to be a 32" high table
by about 30" wide and 48" long.

Ok, you need to think about two things besides simply the weight of the
sander. First, this is a power tool, and thus you're not just dealing with
static loads, you have to consider dynamic loads as well. For example, if
you're sanding or buffing a part and the machine "grabs" the work, your
table could be subjected to a very large impulse force. That would be a
bad time to have your table collapse. Second, a table of that size is much
larger than what's needed by a drum sander. Which means it's likely you
will put a lot more stuff on it (either additional tools or parts that
you're working on). So now, you're subjecting the stand to a lot more
weight than just the drum sander. Plus, if you use the table for hammering
parts, etc., well, I think you get the point.

Again, I would recommend MIG welding. Another poster suggested bolting the
table together, and that would be a viable secondary option. But MIG
welding it will likely be easier, cheaper, and stronger.

If you live in the San Francisco Bay Area, I'd be happy to do it for you
for a nominal fee. If you post your location, there's a good possibility
someone on this list will be able to assist you. If not, you should still
consider hiring out the job to a weldor in your local area. It shouldn't
cost too much (probably on par with buying bottles of MAPP gas and brazing
rods).
