Hey this is my first instructable. I made a simple ring out of stainless steel pipe.
You will have to enlarge some of the images as it doesn't show some of them properly minimized.
Step 1: What You Need
- Stainless steel pipe
- Hacksaw or angle grinder
- Pipe grips
- Piece of tube to bend pipe round
- Files, sanding paper/drill attachments, scotch pad
- Wire brush
- Vice & workbench
- Tape measure
Not everything here you will need, it's just what I used, there are probably many alternatives if you don't have all of these things. Although you will need a welder.
Step 2: The Pipe and Tube
The pipe I used had an OD of 6mm and an ID of 3mm. Thickness 1.5mm.
I cut this at approx 52cm (520mm) in length
The tube I used to bend the pipe round was 1.5 inch (38.1mm).
Step 3: Bending the Pipe
I clamped the pipe at the top of the jaws on the vice pressing against the 1.5 inch tube.
I could wrap it round by hand fairly easily apart from the last bit which I used the pipe grips for and a hammer to knock in the end.
Step 4: Cutting
I marked each end with a marker to cut off the ends "The straight bits"
Firstly I cut off the first ring using a screwdriver to separate the loops so I wouldn't damage the loop below.
After doing this I realized I could just cut straight down the middle of all the loops which cut out the final 2 rings, I had a piece roughly 20mm left over.
Once cut out you will notice the gap between the two ends.
Step 5: Joining the Ends and Welding
The best way I found to bring the ends together was to squeeze the ends towards each other with the pipe grips and then clamped it in the vice at the same time. This brought the ends together evenly and square.
Whilst still in the vice I tacked the ends together with a TIG welder.
MIG or stick will probably do the job, although tacking it may be a little trickier, also filing down the welds after will be much harder, will just take a bit longer.
I had the welder on 24 amps which seemed to work fine whilst welding up.
Step 6: Cleaning the Welds and Finishing
Firstly I went over with a wire brush.
I got away with just using one file with the half round edge. Although as round one would do the trick.
I used a sanding attachment with the drill to help clean up and finished with some green scotch pads.
