The scrap-iron patio table is a basic metalworking project. Essentially, it's an exercise in recycling, welding, and grinding.
Being able to weld is a FANTASTIC skill. If you don't have any experience welding, I highly recommend that you learn from a friend or through a class at a technical college.
Even if you don't own a welder, that's no reason no to learn. There are now "hackerspaces" and other tool-sharing groups and collaborative workspaces which provide specialty tools and training to members. For example, in my area, we have the Milwaukee Makerspace
. Members who don't own welders or shop space for them, use the welders at the Milwaukee Makerspace!
For this project, I used
3-foot diameter cast-iron grate. (This could be any material, but the unique grate is really what makes it special for me.)
1&1/2-inch diameter steel pipe (about 6 feet)
1 inch by 3/16th inch flat iron stock, about 18 feet long total. (this is the same material I used as the corners on my anvil stand
2 each 3/8th inch bolts, nuts, and washers
Spray paint and primer.
To build the project, I used primarily an angle-grinder and welder.
4&1/2" angle grinder
Metal-grinding, Metal-Cut-Off, and Flapper discs for angle grinder
In addition, a face shield is highly recommended for metal grinding.
