Recently, I discovered you can buy these, and the commercial version probably holds
alot more then mine, but it is fun to make your own cold war spy gear.
This might not work very well if you carry it around in your briefcase or something,
but in the proper place the bolt is probably one of the best hiding places ever.
You only need a few things for this
- Two bolts, one big one small
- Hack saw
- Drill Press
- Tap and Die set
- High strength putty epoxy (PC7 works great).
It would be really cool if someone with more know how then I would make one of these that was a flash drive.
Step 1: Remove the head
Try to make the cuts as smooth as possible.
Use a file on the large bolt so the head and the shaft can be put back together flush.
This is not necessary on the small bolt.
Step 2: Find the center
Use a punch to score the spot to help the drill bit
bite in the right spot.
Step 3: Identify the correct drill bit and drill
use this on the small bolt to determine the correct tap to use.
on the tap it should tell you what size hole to drill.
Once the correct bit size is determined drill your hole into the shaft.
- Set your depth, you don't what to drill all the way through.
- Secure the shaft.
- Go slowly and use thread cutting oil, it really helps.
Step 4: Tap the Shaft
Screw it in then screw it out, little bits at a time.
Use the little bolt to check if you have gone far enough.
It only need to go in far enough to hold good.
