Taz I have to admit, I had my doubts at first that you were who you said you were. But I worked in customer service long enough to instantly recognize two things from the way you write: you have definitely worked with a lot of chastity belts professionally, and you have DEFINITELY dealt with a lot of impractical questions from the public about them! 
punishment for arousal
Taz 3). Vaginal probe with pH sensor. Maybe but what is the normal vaginal pH and how if at all does it change with arousal?
Sounds like a setup for a scientific study. But I believe that would still be pretty prone to false positives (probably more error-prone than penis measurement in males, but less than the moisture sensors). Heck, even penis measurements can be triggered without a lot of sexual arousal, not even to mention being close to orgasm.
Saintprudence I don't blame you for thinking I wasn't Tollyboy after all it was a bit unlikely that I would appear here.
As for impractical implausible suggestions from the public you are correct it seems some people don't even give 5 seconds thought to a problem or believe I can do it by magic.
If the group is interested I might one day start a new thread on the odd, impossible and dangerous things I have been asked to make.

I certainly would be.
I wonder, what is your view on the devices being used outside of consensual couples' play? Most statements I have seen from manufacturers on that issue were rather negative, but several members here appear to be in an arrangement somewhere between being persuaded and pressured to wear those devices.
Okay, I will start a new thread on the weird and wonderful things I have built or been asked to build.
The non-consentual wearing of belts is a minefield. In most cases, I don't and never can know enough of the family dynamics to know if belts are being used non-consensually and if they are why. I generally work on the theory that the customer is sane and will use the belt in accordance with the laws of their country.
I knew of two cases of definitely non-consensual wearing of Tollyboy belts and I had no trouble with either case.
1). A young woman with mental health issues who was frequently hospitalised after forcing broken beer bottles into her vagina. She needed psychiatric care but didn't get it, her parents couldn't watch her 24/7 so, in the end, had her fitted with a belt. Not an ideal solution but it did prevent her from inflicting more horrific injuries on herself.
2). A father of Middle Eastern origin who decided to have his daughter belted instead of infibulated.. I'm sure she wasn't happy about the belt but considering the alternative, I thought it was the best outcome she was going to get.
Taz I'd be fascinated (and probably appalled).
Taz I would certainly look forward to such a thread. I’ve seen so many crazy sci-fi fantasies on the forums that I can only imagine what’s been asked of you!

Obviously there is only so much a manufacturer can know, especially in the sex equipment field where customer privacy is taken rather seriously, but I am sure some buyers volunteer way more information than you asked for. I know that My-Steel's old page had warnings on there telling people not to expose the belt to minors or use them on non-consenting wearers - something some buyers do seem to be ignoring, if the stories here are to be believed (and since they are familiar with the trials and tribulations of wearing chastity devices and the people with lock-it-up-and-throw-away-the-key fantasies tend to not last very long, some of those experiences are rather believable).

For me, the motivation is mainly that with an engineering background, one tends to be pretty familiar with the people who think that coming up with an idea is the hard part and realizing it is just applying steps that you learned somewhere. My own field is electronics, so hearing what a metalworker has to deal with would be an interesting change.

Talk about a rock and a hard place. On the one hand, it is not nice to be complicit in the subjugation of girls and young women, on the other hand, middle eastern infibulation typically involves some form of FGM and you would obviously want to do what is in your power to save at least that one victim from that.
Well, I am well aware that there are special methods. @Sara2001 could orgasm by rubbing her breasts, but I was a little confused because I was thinking of the classic version, maybe I'm too old-fashioned for such discussions. 
Ines I doubt it... I do not think that I have such power!
Taz nd mental stimulation.
I really need to know more about this, can you train it?
Maybe he meets someone he liked a lot(maybe you,as someone suggested)!
Taz or ideas that owe more to fantasy fiction
Probably,yes
Angelina point 6 was supposed to be effectively prevented by the belt?
Right,I was surprised to read it,too.
youdontknowme No wearable belt is completely orgasm-proof
Never been able to get one,with my belt on...
youdontknowme I assume those are the orgasms that the belt is supposed to counteract by punishment
Possible,yes.
Taz If the group is interested I might one day start a new thread on the odd, impossible and dangerous things I have been asked to make.
It could be interesting,yes.As long as it doesn't give bad ideas to some trolls or fetishists(for the possible but dangerous ideas).
Taz The non-consentual wearing of belts is a minefield.
Not that much.Here,we're almost all against it.
Angelina I was thinking of the classic version
Me too.
Vanessa It could be interesting,yes.As long as it doesn't give bad ideas to some trolls or fetishists(for the possible but dangerous ideas).
i worry about that too, when we write about it we have to mark it clearly with the fantasy tag so that no one (especially parents) gets the wrong idea.
Vanessa Never been able to get one,with my belt on...
Different people take different amounts of effort to reach orgasm. If you are the sort of person who does not orgasm from mental stimuli alone or melt to gentle touches quickly, chances are you will be a lot luckier (depending on your definition of luck of course) with the effectiveness of your belt than someone who does, even if they wear a belt of the same design, with the same amount of effort spent on getting it fitted to their body. Heck, there are even women who struggle to orgasm despite never even having seen a chastity belt, much less worn one.
Other factors to chastity belt effectiveness include things like how much mobility restriction you are willing/able to endure (e.g. thigh bands), and your access/willingness to use technical help like high-power massagers.
Fantasy tag,good idea.
I would not say I'm lucky about it,no...
About thigh bands,I've these on sometimes,but not permanently.
I'm not allowed to have such massagers,bit I've tried a few times with some ex,without success.
No, I would never punish my daughter for arousal, or for trying to get around the belt. She should not feel guilty for feeling aroused and acting on it.
shinydiamond77 or for trying to get around the belt.
but i think you would do something about it if it had any chance of success (like thighbands etc.), that would be a kind of punishment. ?
No. If she finds a way to bypass the belt, there isn't much I can do. Thigh bands are absolutely out of question, just no.
It's very unlikely she can bypass it though. I don't think it's physically possible.
good that you are not thinking about thighbands, but i doubt that it is not physically possible, we just haven't found the right way yet.
Vanessa Works well without the belt,and not at all with the belt...
that is good
