Metal Self-Bondage
From this post on the The Bound Forum, a metal-heavy self-bondage setup:
Having completed a recent purchase binge I have come up with a nice restrictive all metal setup to have a nice nap.
First thing is to lock the ankles in Irish 8 leg irons. Then I have Hiatt oversize ankle irons that fit my elbows perfectly. They are Quik Linked together (those little oval connectors that screw closed- 1/8″ smallest available; can be tightened with wrench for security) and chain goes to Darby style neck collar. Arms are in front.
Next for the wrists is Hamburg 8 style handcuffs. Easy to use and very comfortable; rigid but hinged. Then come the thumbcuffs; double locked of course.
This setup is easy to get into and out of. Comfortable for nap but metal bondage all over.
