Make a Modelers Orbital Sander Out of a Toothbrush
Intro: Make a Modelers Orbital Sander Out of a Toothbrush
I make a lot of models and since I am always short of cash, improvisation is the norm. So trying to sand a new coat of primer in the tiny crevices of a model I had the brain wave to use an electric toothbrush as an orbital sander. 5 minutes later, success!
This works so well and with disposable toothbrushes being so cheap, I have several of them with different grades of sand paper pre-bonded for different jobs.

STEP 1: What You Need.
An old toothbrush (preferably your own)
Some form of contact adhesive
Heavy duty scissors
Sandpaper
Coffee

STEP 2: The First Cut
I tried various methods of getting the "Mat" that holds the bristles off, even tried burning them first but have now settled on this method as the quickest and least smelly. The bristles are mounted on to a mat that is easy to pull out in one go if you can just gain access from one or more sides. Make your arrow head shaped cuts to the head of the toothbrush and peel the mat off and discard.
STEP 3: Glue and Grit
Once you have achieved the desired shape of the head for the project that you are busy with, liberally coat the head with contact adhesive and allow to dry. Coat the non-grit side of the sandpaper as well.
Once both surfaces are dry, clamp together with clothes pegs for 5-10 minutes.
Job done!

STEP 4: Sand Away!!!
You can now get in to those little nooks and crannies to do the work that can be the difference between an okay model and a really good model. Once the batteries are flat, then you can throw away the toothbrush.

Since I do not have amounts of one-way brushes hiding in my flat, I´m now thinking about a quick-release / quick change mechanism for using different "tools" (?) on my my worn out sonicare toothbrush. Which wasn´t that cheap, but it´s down and that would be a really cool repurpose for it.
Detail work with "ultrasonic" power :D
I already thought about velcro and double sided tape as mentioned in the other comments, this may work for sanding but I think that would not be sturdy enough to attach a file or maybe even a tiny sawblade or cutting disk...
With a sonicare I could imagine that its powerful and/or fast enough to do even finer metalworking...
We´ll see. If I can afford a new one and hack the old, I will post it here, promised!
Keep on!
