Build Your Own St. Catherine's Wheel
» Pervertibles / DIY
Certainly a challenging do it yourself bondage device:
Build an A frame for it to be mounted on out of 3’x 3’ x ½’ steel angle 4.5 foot high
Build a D frame as a base mount for the A frame and support with diagonals using the same type of materials
For the pivot, obtain a stub axel from a auto supplier with two inch studs (you may have to buy these separately) and mount this stub 6’ from the top of the frame
Obtain two lengths of flat steel bar 7 foot long x 3’ wide x ½’ thick, centre the flat bar over the stub axle and mark the holes for two opposing studs and drill the holes, (normally a half inch drill bit is required), do the same for the second piece of flat (I usually cut the second piece in half and weld it at right angles to the first piece but then I use 316 stainless as well) and mount it at right angles to the first piece
The wheel itself is made of 3 inch plyboard cutting a circle with a diameter of 7 foot 1 inch, the centre of the circle is reinforced using a plate of ¼ thick steel profile cut into a three foot diameter circle, this plate is centred onto the stub axle and the holes for the studs are drilled through the plate.
The plate is bolted onto the stub axle and the tops of the protruding studs are cut off, the wheel is bolted to the plate and flat bar using 3/8’ cup head bolts, remember to recess the holes for the stud bolts on the wheel.
Prior to bolting the wheel on to the stub axle have the front of the wheel upholstered and fitted for restraining a subject (I use foot plates as this provides a measure of support) remember though the wider the strap the more support is provided and this is important when the subject is side on or upside down.(be wary of suspending a person upside-down for more than 30 minutes
If possible try and incorporate the positioning of the cup head bolts in the placement of your restraints, this means that you can remove the restraint to clean or replace if necessary and it hides the bolts
The frame should be bolted to a concrete floor an if you have dry wall screw a 8 foot by 6 inch by 1 inch piece of timber across the studs and then bolt the top of the frame to the timber, the timber also provides hanging space for your other implements
This wheel will take the weight of 250Kg or 560 pound DO NOT USE THIS DEVICE IF THE SUBJECT IS OVER 150KG OR 330 POUNDS.
