Re: Compact Spanking Machine

OK, I finished it and tested it! I did some experimenting with the actual spanking part. Because the mass of the spring is much less than the mass of a human arm, there are different considerations as to what kind of spanker will inflict the most pain. Springiness does not help, and the lighter it i...

Re: Compact Spanking Machine

Spring_Tensioner.JPG Here is the progress so far: The whip attaches to the part of the spring sticking out. The motor is on the left, and the actuator on top releases the spring. Mechanical assembly is now complete, I just have to wire it up, debug it and paint it. It is controlled by an Arduino pr...

Re: Compact Spanking Machine

Yes, that would represent the ultimate development of my machine. Right now it is in a very crude form, yet still provided the stimulation I craved so much. Interestingly, if it is operated by an electric motor rather than a rope pull, a pair of AA cells would provide enough energy for some 900 real...

Re: Compact Spanking Machine

Thanks, Thub56! Unfortunately McMaster doesn't sell a spring anywhere near this big, but they WILL wind me a one - of custom spring, for a price. I have not yet gotten a quote, though. I did find a couple of springs that are too large for my personal taste in spanking, but are inexpensive and off th...

Re: Compact Spanking Machine

For the tech heads out there - the spring has a force of 90 pounds and a stroke of four inches, for a stored energy of 20 Joules. I am guessing that around 50% of this ends up in the cane itself, the rest is lost to friction and kinetic energy of the other parts. 10 Joules does not sound like a lot,...

Re: Compact Spanking Machine

Re tension and hook it by hand. Pulling the string releases the spring. Takes about 10lbs of pull, and the powerful swat comes immediately. I have found a better end effector - a length of 1/2 inch diameter G10 glass/epoxy composite. My lover is a tennis champion, and she generally gives me 10 swats...

Re: Crued Spanking / Whipping Machine ideas?

I built a simple spring powered spanker here:-
viewtopic.php?f=12&t=13142
It has almost unlimited power, depending on the spring(s) you use. It an also spank as gently as you want.

Compact Spanking Machine

Hi There! My spanking partner was stuck out of state for a while, and I was getting desperate so I built this spanking machine to use until she returns. The main thing is the compact size, it simply bolts to the metal frame of our queen sized bed. I simply drilled two extra holes in the frame, which...

Re: Self Tightening Belt

Hi Bound_Jenny, Thanks for your input, and congratulations on your waist reduction. 20 inches is impressive, considering that the world record in a living person is only 14 inches. I myself am not trying to reduce my waist measurement, I just like the sensation of pressure that I get from tight laci...

Re: Self Tightening Belt

Very interesting. I could use a set of these as a part of my system, thus avoiding the need to design them myself! As to the absolute mechanical limit, I will, of course, install such a limit if the winch mechanism does not already include it. I will also use a mechanical weak link for additional sa...

Re: Self Tightening Belt

Thanks for the link to the story - it is awesome! Of course one could not easily make a lightweight belt with sufficient power, but mine will be floor mounted and have plenty of power. Also I plan to use mine for 45 minutes rather than 45 weeks, but then again, so did the hero in the story... Thanks...

Re: Self Tightening Belt

Hi Shannon! Please could you tell me where to find that story? I cant seem to locate Gromit's Plaza anywhere. As to making the machine, it is pretty straightforward. Just the winch that I linked to, a low end Arduino and some simple software. Not saying that it is inherently safe - the winch can pul...

Is there anything that SHE would like that you could do together? You would be much better off adapting to her wishes than vice versa.

Re: Self Tightening Belt

The winch would be automated using an Arduino microprocessor or whatever. So once I push the button, it goes through a pre-programmed sequence of tightening over which I have no further control. I would also have my arms and legs tied down, only to be released once the tightening sequence has been c...
