making a boom pole?....

[Farwell]

I think you may be further ahead if you go to a metal salvage yard and get some heavier gage steel. I am like one of the other posters on this thread said, "always trying to lift things heavier than the boom was designed to lift". The end of my boom pole is much closer to the ground than it once was. I have used galvanized steel pipe for many things and found that it is great for some things but it is quite soft and bends much easier than the heavier gage steel tubing. I also like the stick welder for the heavier welding projects.
I like the 3pt hitch thingamajig you found. It is simple in design but looks like it can do many things for you.

Here's one I made from some scrap schedule 40 galvanized pipe and pieces of 1/2" square steel. I used a stick welder on this one. Pipe was bent on a hydraulic bender I rescued at a company garage sale (real cheap). With the rig you found, I'd make it detachable so you could cobble up some other "attachments". Looks like it could be fun.............chim

Edit to add: I can get the front end of the tractor - a B7500 - off the ground without affecting the pole.

When you weld galvanized metal it gives off phosgene gas - which is one of the things the English, Germans, and French used to gas each other with during WW1. If you using MIG or TIG the galvy can contaminate the weld too - grind off all the galvy in the weld area and you should be ok. If you are worried about corrosion you can use steel and then paint it afterwards with one of the spray galvanize coatings - RustOleum makes one that works really well.

Sorry, but I believe you're mistaken about the phosgene. The fumes from welding galvanized steel would contain vaporized zinc and zinc oxide along with iron vapor from the steel and maybe lead vapor too.

Phosgene is a compound of carbon, oxygen, and chlorine. I can't see where you could get any chlorine from galvanized steel, and not much carbon either.

With all respect,

Welding near perclorethylene (dry cleaning solvent) DOES produce phosgene....It is NOT PLEASANT!!!
So...please leave your welder in the car when you get your suits.

Must be one of those urban legends about the phosgene coming from welding galvanized metal because I have heard it from numerous sources over the past 50 years, may have even read it in welding manuals. Have to check that one out. I still am going to use plenty of ventilation when working with galvanized metals.

Although I didn't think of it in my earlier post, I think the main worry about welding around zinc is cadmium vapor. Like lead, cadmium is an impurity found naturally in zinc and is pretty toxic stuff. In recent times, the safety folks have gotten pretty concerned about our day-to-day exposure to cadmium. Like lead, it accumulates in our bodies and in most of us, the amount starts at zero at birth and maxes out around age 50.

As bobodu said, welding around chlorinated solvents like perchloroethylene or trichloroethylene (TCE) can produce phosgene. Since TCE is used as a degreaser, it seems possible that someone could use it on some steel, and then weld soon after, making a little phosgene. As long as the solvent had dried first, though, I wouldn't think there would be much of any residual TCE or much phosgene either. I could be wrong.

A good way to get rid of the galvanized coating is to dip it area in Muratic Acid and flush with water. Well ventilated area, etc, etc, etc...........

<font color="green">Lot's of good advice in regards to protecting one's health while welding.

Someone smarter than me is going to have to explain the above quoted precaution.

Seems like it should say to use blowers outdoors when it is NOT windy. /forums/images/graemlins/confused.gif
