When I did 2 strokes in the past, I soaked the head in Acetone for about 3 hours to get everything good, and clean, then if I had issues , I would heat it up a few times let it cool ,and re soak it. That seemed to work every time for me.

You can braze copper with silicon bronze, get it really clean. I don't know what you are working with , but thin stuff is a real challenge.

Solar flux is what you need, but it will leave a grey glass like coating as it bakes in, and it isn't food safe.

Sorry guys. I was using this weld as a before grinding view. It's not that big. It's 1/8" material. The little divot at the end wasn't the issue. I think after it's ground it seems to have some porosity hidden under it and I'm not sure why. I brush it and use acetone but I guess it's still not...

I don't understand what you are talking about, sorry.

Yes keep a clean tungsten , and have enough stick out to get a nice tight arc , and make sure your surface is clean.

Not weldporn quality, but you probably will grind most of it off anyway, and they should function just fine.
It looks like you got plenty of penetration.

No it is off a Dyna 3/4" axle and trust me I know all about Harley and there Tech I have been wrenching on them for over 15 years professionally and own my own shop working on nothing but HD's. On the Dyna Models with the 3/4" axle the torque spec. is 60-65 ft lbs. I figured to use 70s2 b...

Why not buy a piece of unglazed ceramic tile, snap off or cut bits to fit around it , and tape it with aluminum duct tape?

You can bet if it's Harley it isn't anything special. I ride one,but they boast old tech.
Is that swing arm off of a touring bike? I ask because if it is my rear 1" axle is torqued to 105 foot pounds, and mine is an 03.

I have done this type of thing before, and I found a piece of tube that both pieces fit in , and cut a window out on it, and slid in the pieces welded them, and left them in the tube to cool, they stayed pretty straight.

Take it from me , do not get sucked in. Sure it's fun, but you probably will not make a living doing it.
I am a technical director, for a small theatre in Indianapolis IN, and I see all kinds of people trying to make a living at acting.

I use the same tungsten for everything, and have not had a problem at all. There may be a case some day where they say you have to use a new tungsten , but I haven't seen that yet.

Until about a year ago I used MDF and about 6 saw horses under a 5 x 10 sheet of mdf, that was 1" thick, it worked pretty well.

AMEN!

Looks real good, now challenge yourself , try to weld a piece of 22 gauge disk to a piece of 14 gauge tube, with the tube passing through the 22 gauge. I am saying this is hard , because I just had to do it 48 times, and I didn't get really good at it until the end.

I am sitting here reading this , and both of my hands got bloody today, broke a tap handle, and busted my knuckles, then the other hand slid across the broken part, and I almost pissed down my leg when I picked up and moved a soaked with Acetone towel....

Bill, what model is your saw, and what was the wall thickness of the square tube?

It's a Raptor 14" the 304 stainless is 14 gauge , we cut some 1/4" x2 inch bar with it too.

Thank You! I will take all of the help I can get.

I have an evolution chop saw with a stainless steel blade , and it is pretty much trash in one day of cutting 1 1/2" square tube.
How do I make the next one last?
I tried cutting with no pressure to start, and then shot it with wd-40 , and the blade is cutting pretty bad.

Not really, because the idea is that copper coated bbs wouldn't stick to your weld. I thought that copper shavings from a lathe would work pretty well.

These folding style portage wheels were made after hours by a welder from a mining company on the Iron Range in northern MN. He no longer makes them so I need to make my own. If you guys get me onto the right size metal I'll be in good shape. I'd hate to have the metal fail on me on the portage. If...

In the summer time I have found that a white long sleeved cotton t-shirt works pretty good, but I usually use welding sleeves, and an old welding jacket that I cut the sleeves off of because they had so many holes in them, I have been lit up because of some of those holes in the sleeves that I cut o...

Hit the pedal with the torch near your ear , do you hear gas? Wondering if you have a big leak somewhere?
Is your tungsten eroding really quickly? The curve ball you are throwing is that it works on stainless.

Remember 1/8" cable can hold 1760 pounds if stainless, or 2000 pounds if you use galvanized, 1/8th inch gets 3 crimps, and 3/32 gets 2. Hey Thespian! Now that's inspiring help! My girl is a professional fire performer so we know a lot of others too so I understand the necessities and concerns b...
