Custom Sized Rubber Bands
I need a couple of small rubber/elastic bands for a task and didn't have any, I could have twisted the ones I had lots of times but didn't have the space so I made a couple here is how.
Materials
you need:
a longer rubber band
a sharp blade
cyanoacrylate glue (CA)
Cut Size and Cut
cut your band open.
establish how big your new band needs to be.
cut to length. get your cuts as square as possible.
Bond Ends
note the photo is for illustration only I used both hands for real.
Apply a small drop of CA to one end of the rubber.
bring the ends together and hold until set.
The properties of CA that make this possible are it's fast set & it is very strong in tension. I've even used this method for making drive bands for small motors.
It also bonds skin use a very small drop and avoid over spill. wearing rubber gloves or using tweezers is probably advisable.
Use
As you can see I wasn't too careful with the measurement and still ended up doubling over. I should have cut under size. This does however show the joint takes the band being stretched
