I'm late coming into this thread.  Holy smokes!  Probably a good thing I didn't get a chance to vote while I was on vacation, I would not have been able to make a choice!  Outstanding!

Yes you can you just have to be careful not to get it too hot it will solder/braze just like copper etc. I do it quite a bit but mainly use propane or mapp gas and aluminum rods it makes for a very strong joint. It is actually very easy. I have a smith torch but it's packed away and I haven't used it but will be if I can find it so I can get a finer flame for pin point welds. There are lots of YOUTUBE vids on it. Here are the type of rods used I haven't used this particular brands I got mine from ACE and then some from HF didn't really notice much difference in brands.

Thanks... My sister's in-laws live in Vancouver, so I might actually have a chance of going out from there. Less than 2 hours drive to Hope... Though it looks like they really don't like people parking near the river (the internet says because it's a popular spot to get salmon later in the year).

Sandsave, that is a killer Laguna!

I'll go ahead and enter this month.  It's been a while.  My 12 year old son and I collected many different types of agate this summer in southern Colorado.  We found quite a lot of blue agate, which I'm really excited about.  It's not as deep blue as I had hoped after it's worked, but still interesting I think.

Thanks everyone for your kind comments. I'm a little slow getting them done as we are having a bit of a heat wave here in San Diego. Makes the garage too hot to work in. A little cooler this weekend so... :headbang:

In the presence of heat and oxygen aluminum will turn to aluminum oxide.  It will loose coherance and all you will have is powder.  Aluminum can only be welded with an oxygen free heat source and protected from atmosphere.  That means the only practical means is MIG or TIG unless you happen to have a powerful laser.

So, I have gone through all of my jewelry making stuff, and separated out a bunch of things to keep, and things to sell.

I have a question about the Smith's Little Torch that I used to use for Silver soldering.

It's a propane/oxygen setup.  Would it be possible to use it for aluminum brazing?

I'm not looking to weld aluminum, just brazing to attach aluminum frames to aluminum wall art.

If it is, is there anything different I would need beyond the typical soldering set up?

I'm not talking dremel speeds (< 35K rpm) but rather full-on dental drills that do 400K rpm and run off compressed air. Some of the small inlay work I see where shaped stone is set in jet makes me wonder how it's done.

Winter is normally out except for locals who are very aware of the fluctuating water conditions. Rivers here are at their lowest (if they have no dams) in August but by that time  the areas may be quite picked over. A nice period exists in the beginning of spring when the water levels have gone down  because the rainy season is waning but the snowmelt has not started in earnest. Snowmelt here is a big issue at least through June and people die every year because they underestimate  the force and volume of the snowmelt.If you are  coming a long way August is a sure bet but most years the air quality is mixed at best due to the fact you are then deep within fire season.Good luck.
