2 1/4” OD round metal tube

[Jake18v]

Well that solves it. Now I just have to see if my Milwaukee 1/2” bit will cut thru the ci pipe.

I’m going to use the ci pipe as the bottom pipe on a 2 part pipe. I’ll use my existing top steel pipe and plates and adjustment screw.

$$$ saved.

Thanks guys. I’ll be back to ask some newbie welding questions.

I’ve got plenty of 2” CI pipe from plumbing projects.

Not cast iron, black schedule 40. Technically it’s steel but often commonly referred to as “black iron” as opposed to the galvanized variety. Sorry, I used a bit of older jargon there and could have been clearer. Cast is indeed more brittle amd I would not suggest it for your application if it’s carrying a load.

....or welding to it!

Arch City Steel has an amazing selection of tube sizes; they've been a big help for many work projects! And they take credit cards...

I might have 2” black pipe in the basement as well. We’re talking about the black steel threaded pipe used for gas lines, steam radiator piping?

You could just use wooden blocks stacked in a cribbing fashion to raise your jack height, ideally using 6x6 blocks.
Here is one idea:

Yes, that's the stuff.

Actually I think pipe is measured by ID and tube is measured by OD.....at least at https://www.metalsupermarkets.com/

Your absolutely correct, I noticed my mistake a couple of days latter, thanks for pointing that out. Just a note pipe over 20" diameter is apparently measured by OD, so I've been told.

I have two 2" black steel pipes from old steam pipes I have removed. One of them fit the required height needed perfectly. And the adjusting bolt that came with my posts fit inside the pipe.

The other black steel pipe is short by 5". I've thought of a few ways to solve this:
1. stack 4 2x8's under the pipe and flange to make up the difference.
2. I have a large scrap piece of steel i-beam. I'm guessing 6" width, depth is 5", flange and web thickness about 1/4". I'll update with actual measurements. Can I use that to make up the difference? ITs about 32" long. So it would spread the weight nicely on the floor. (I don't really care about the floor as it's being replaced at some point). I don't really know how the compressive strength of an i-beam is calculated. Not sure it can handle the load. The jack plates I'm using are 4" x4".
3. Buy a 10' pipe and cut it to size. They're not cheap. About $55. And basically useless once I finish this project.
