Extra Hand for a Drink Cup
I have been working on a project in a library. I am able to take a drink cup, but sometimes am short a hand for managing doors while carrying everything. This carrier suspends my cup from the bag for my supplies. A cup could also be suspended from a belt loop or a lanyard around one's neck.
Materials
- 3/16 inch rod
- Links from 3/16 inch chain
Tools
- Caliper
- Hammer
- Vise
- Hacksaw
- Welder
- Grinder
Measure the Cup
I used a caliper to determine the diameter of my drink cup in the area where I wanted to steel ring to support the cup. If the ring can be as high as possible, the cup will be more stable. This cup looks like a paper throw-away, but is actually plastic and double walled. It is from Bed, Bath, & Beyond.
Bend the Rod to Fit the Cup
The rod may be formed around a piece of steel pipe. Instead, I made small crimping bends and fitted the resulting curve to the cup, making adjustments as needed.
Does It Fit?
My plan had been to multiply the diameter of the cup by п (3.14). I even allowed a little extra, but still came up short.
Chain to the Rescue
I cut the end from a link of chain and welded it to the two open ends on the ring. (At the end, I welded a short piece across the link of chain to keep the handle from sliding down around the ring.) The chain link allowed some final adjustment of the ring size. I could squeeze the chain link in a vise to make the ring a little smaller, or I could drive a wedge, like a cold chisel, inside the link to spread it and make the ring larger.
Bend a Handle
I bent the end of a piece of rod like a shepherd's crook. The tool I used is described in this Instructable.
Attach a Chain Link to the Handle
I opened another link of chain enough to slip the end of the rod handle into the opening. I slipped the link of chain over the link that closes the ends of the ring. I welded the handle rod to the chain link.
Grind Smooth and Use
I ground away any roughness in the welds.
The finished carrier folds relatively flat when not in use.
