How you doin'?
Well, I'm two months into a six month hiatus of not working. It sucks not having any income at all, but the stuff I'm getting done will most likely never have to be done again in my lifetime at least. It's never fun to put your 40 in every week and still have some major project unfinished that drags out for months it seems. Two more bedrooms and lots of little stuff are done now....I've got a pantry, walk in closet, and two bathrooms to do yet. Then the inside is finished other than maybe a good wood burning stove in the living/dining area.
I'll likely start seeking employment in May unless something pretty good comes up before then.
Depending how the material was galvanized.Quote:

Galvanized steel can be welded, depending how you prep the material. If i must weld some of it, i'll grind then finish with a flapper disc to get down to bare metal.
I also have both fan behind me and an exhaust by welding area. Scenarios of welding can be slight headaches to something serious, depending how much exposure you have. 1 or 2 welds, not an issue.
I mentioned this since you're probably in the garage dong this. You don't want those fumes moving around the dwelling and or wife, daughter in area. The effects vary depending on ones sensitivity .
"Fumes from welding galvanized steel can contain zinc, iron and lead. Fume composition typically depends on the composition of materials used, as well as the heat applied by the particular welding
process."
Another factor that will help to make quality welds is the type of galvanizing process that was used to coat the steel. Different types of galvanizing methods will leave different thicknesses of zinc on the steel surface. Hot dipped galvanized steel and zinc thermal sprayed steel will typically have a thicker coating than zinc electroplated steel. Selecting a zinc electroplated steel can result in a better weld than thicker-coated hot dipped or zinc thermal sprayed steel. Zinc electroplated steel will also have a far more uniform coating which is important when welding automation is being considered.
I was up until 1:30am welding last night. I kept having to open the garage to air out it, but was keeping it closed so I could use the grinder without disturbing the neighbors. I'm going for the record to see how many times I can forget to move my ground clamp between pieces. So far my record is every fucking time.
For as many resources as I've read watched about welding, I have a hard time coming across something that explains how you're supposed to adjust what you're doing depending on the angle. In this case I'm trying to weld hinges on to the ramps and trailer. I can manipulate the ramps to weld on a comfortable position, but have to lay on the ground and weld upside to get the bottom side of the trailer hinges. They look like dog shit and I don't know what to create better over head welds. At least I burned the shit out of myself all night.
Best bet is to set up circumstance to avoid welding upside down. Plan it in to your project.
Cleat or ledge mounted before hinge to weld hinge to, maybe different shaped hinge plate/base.
If I weren't rushing to do it before bed, I would have just flipped the trailer over.
Pull it outside, flip over and grind those welds off.Quote:

Hey Irving,
Want a ventilator fan for your garage ? You just need a window or hole in the wall for it.
Yeah, I think so. What's the size?
