Default Can I weld this to this?

I am hoping to weld this pipe onto the weight to make a stand for my grinder.
I am guessing the weight is cast? And if so, can I do this or not? I did a search but can't seem to piece together the info I need.

How does a spark test with a grinder work? If its cast iron/steel what will the sparks look like?
Or scrap the idea and find a new base?

Thanks, Dan

Dan that weight is more than likely cast steel.... for a grinder stand fit the parts up and have at it with your fav. method I.E. MIG stick TIG O/A..... if it is cast I'd do it the same way :evil:
EDIT:
I'd flip the weight over and have the flat part down and if the pipe wont fit over the center notch it out so it will slide down some

From the looks of the dents in the weight, I'm siding with steel.

Take a 3/16" drill bit and drill into it. steel will create a chip, cast-iron will crumble like sand.
Post a picture of the chips.

Is 35 pounds really enough weight?

Ya know, I thought about that at first, but then realized it's likely more than most truck rims. The difference I see though is the diameter. Seems like it might not spread the weight out enough once the machine is mounted and it gets top-heavy. Then add to that the pressure from a hoe-blade or something and I could see how it might easily tip.


Welding to it, for it's intended purpose, shouldn't be a problem though. It might be tricky to make it look purdy, but you should be able to get it to grip enough to hold up.

Maybe I will offset the pipe, toward the back. So it has more of a footprint in the front. Its just a 6" grinder.

GWIZ, that's great! I will try it right now

I'm still thinkin that wont work.You'll be pushing against it, trying to push it over backwards. If you offset the pipe, you need the bigger foot on the back.I would probably do something different, like a steel rim....
And sparks on cast iron are short(3-4") and dull red, with very little, if any, sprigs. Mild steel is a lot longer (3-4 feet) a brighter red or yellowish, and some sprigs, sometimes...

Dan it is hard to tell the diameter of that thing.How big is it?
When you add probably 4 ft. of pipe and a 20# grinder that thing more than likely will fall over on you.
If I was doing that I would go and find a truck rim or something else that had a bigger foot print. Something that would give you around a 24 inch foot print.

A 35 lbs plate is about 15 to 16 inches across
