foot pedal

[purdy]

alright guys. So.... i've been meaning to post this for a while. I have developed a new foot pedal to be used by the glass creating masses. It is capable of metering both oxygen and propane by only your feet. Imagine separate wah wah pedals, each controlling the flow from both gasses. they work extremely well, and Im ready to start mass producing them. Pm me for more info. Feel free to ask me any questions!

[purdy]

you put your foot on both of them and slam 'em back. simple as that.

[Role]

Pretty cool.

Definitely heavy metal. :guitar:

[Emmett's Glass]

What valves are those?
E

[purdy]

They are standard b fitting valves.......just modified...a bit

[misticglass]

Simple, yet effective!

[Icarus]

Awesome. Would love to see somw video of that bad boy in action!

[LooseSeal Baller]

So does it work like a typical foot pedal? You adjust outer flame by hand, then use pedal to turn on/off, or what? How much r u charging?

It doesn't appear so. It appears that he means to adjust the quantity of fuel or gas delivered via his feet. Imagine if your torch valves were on the ground and you turned the knobs with your toes, and you're just about there.

[LooseSeal Baller]

Think I would prefer regular foot pedals

[purdy]

These have the same on off action, but also a myriad of settings in between. Trust me, this thing rocks. It is a very unique pedal, and ive gotten great results.

[Bo Diddles]

So how much?

[purdy]

Ill have a video up later in the day!

[BK]

best foot pedal around. period.

[ramanglass544]

but will it bail my ass out of jail? or deal with my herpes?

[purdy]

I dunno about you, mike. Might take more to post your bail. But they go for 500.

[MarioSC]

That's bad f'n ass and a awesome idea! Is it just tha one foot switch that controls oxy & gas flow or is it 2?

[Emmett's Glass]

How about a maker and part number.
E

[purdy]

As it is a one of a kind tool of my device, i'd rather not share explicit details as to it's construction. At least until i see a positive response from the first run. So far i could not be happier with the results.

[Emmett's Glass]

So you're telling me that your an asshole because I asked a specific and you gave me a bullshit answer.
E

[BK]

are you fucking serious? Die in a fire.

[purdy]

Wow. Just wow.

[Icarus]

Wow, this took a turn.

[themoch]

I think what E is trying to get at here is that safety with a valve system is pretty important. We've seen a lot of people here use shoddy valves that were not meant for pressure or oxygen.

at least that's what i'm getting out of it.

[purdy]

They are osha certified, "b" fitting valves. the unit that you see in pics has been in use for months without any signs of malfunction. That is why, now, i feel comfortable posting my work on this forum. I just hope i may pique some interest from those of you that want to see something new.

[Emmett's Glass]

Now you're just making shit up, OSHA doesn't certify valves.
E

[purdy]

This is what makes me not want to share anything with anyone. Emmit, Please use an open mind. Please try to hold back your hostility towards me, where ever it may come from.

[purdy]

For anyone interested, video will be posted this evening.

[Greymatter Glass]

I think the name calling is a little unnecessary, but we have some concerns...


They are osha certified, "b" fitting valves.

There's no such thing. ASTM, DIN, IEEE, ASME, etc... they are certification bodies. OSHA is a governmental employee health and safety oversight administration.

"B" fittings refer only to a size and style of connector commonly but not exclusively used in the welding trade on small bore hose. There's no such thing as a "b fitting valve" just a valve that has been designed or modified to couple to a system with b fittings.

Using technical jargon comes with the risk that the people you're talking to might know more about what you're talking about than you do. You've already greatly damaged your credibility in doing so... please just be humble and recover what you can and continue...

Without giving exact part numbers I think you should be able to tell us what the materials are, what the valve packing is made of, and what the specs on the valves are for use in high pressure high velocity oxygen and LPG service. If you have mechanically altered the valves they're no longer to spec, and so what measures have you taken to verify they're still safe?


It's one thing to make something for your own use at your own risk, selling it and assuming the product liability is an entirely different beast. They may be ok for a few months, what happens in 4 years when someone's shop burns down? Will you be able to show to a court that you used the proper and safe materials?

Also, Carlise, Litton, and Knight all make foot controlled proportioning / metering valve systems. How is yours different?

[purdy]

When i said osha certified i was refering to the fact that the fittings on the valves are osha compliant. Meaning that each is distinguishable by thread pattern and markings. Whatever has been misconstrued, i apoligize to all. Greymatter, i fully understand the concerns you have raised. I have thought about these in depth, believe me. So all i can say at this point is check it out, its kinda cool. Thats all.

[Emmett's Glass]

Yeah, what Doug said about the fitting/valves.
I could care less about the fitting you use for the valve, I have a project I wanted a simalar type of valve, not get a bunch of bullshit answers that sidestep the question I asked, and you accuse me of being hostile.
E

[purdy]

They are standard 1/4 b fitting needle valves. Ill pm you part #s.

[Keshav]

Purdy I think if you're going to plan on selling these, you need to be more open with the product and provide more pics. I understand you don't want to give the design away but if that's your main concern then you should maybe apply for a patent and go that route. Considering that's probably not a viable option, I think you should first build up a supply of these things, get a vendors account, get some proper pictures/vids of the product in action and accurately answer all the questions. All this would give more credibility to your product and will show all the work you put into it. For a foot pedal the price is high, so you gotta be clear how this is different. It seems like a great product, good luck with your sales.

[Greymatter Glass]

See why it's just easier to just say what you mean then? Nothing was misconstrued, you said you were using OSHA certified valves, the only logical inference is that you didn't know what you were talking about. We're not mind readers, and since I don't know you from a stick in the mud, I can't know what you know, how you know it, or why you'd say it.


Greymatter, i fully understand the concerns you have raised. I have thought about these in depth, believe me.

I have seen people make foot pedals for torches using plastic sprinkler valves and have themselves convinced they're doing it right... Nothing really surprises me any more... I'm just curious as to what kind of research you did before making this valve.

So can you answer the following questions?

1. What is the valve body made of
2. What is the valve packing / seat material?
3. Are the valves specified for use in high pressure / high velocity oxygen and/or propane gas service?

Note, I'm not asking if you WILL answer, but if you CAN answer them. If the answer is no then why should anyone trust you?

Too many scammers hide behind some "proprietary" process that turns out to be fairy farts and rainbow pudding. Even more cut corners to keep costs low to undercut competition only to see themselves mired in lawsuits and a crashed reputation.

Also, this isn't anything new, not from what you've described, so how does it differ from existing patented products already on the market?

These are things you should consider before you put something up for sale to the general public....

If you had approached this as a peer review of your design, and offered up full specs we'd be having a different conversation now.

Thanks that's what I wanted to hear, see how easy that was.

[Bo Diddles]

are you fucking serious? Die in a fire.


Ummmmm..... yeah.

[leatherneck8541]

i wanna see some video already:)

[purdy]

Well sheesh, i was just trying to share an idea that i have. It appears as if i am under more scrutiny from you guys than osha themselves. Unfortunately i am not with the pedal, im trying to watch a fully jacketed flask demo by the master dennis. Like i said i will post a video and a bunch of pictures. I dont want to argue with anyone anymore, its been a long night/day, and it doesnt seem like i'd get anywhere anyways.. Untill then...

[purdy]

Ok, here you go guys. Btw greymatter, valves are cast brass with steel needle, I picked em up from my local welding supply store.

feel free to ask me any questions.

[khan]

That looks like a great pedal man. I didnt understand the box on your the left in the video that was used to adjust your flame before using the pedal. I do like the idea of separating the oxy and propane into 2 pedals with control of each.
If you can get the price point down just a bit i think you will move more of them. Thats just my opinion thou.
BTW, i looked at some of your work... and its damned killer stuff. I really like alot.

Khan

[jseden]

The box is just that torch. You wouldn't get one with the pedal

[Role]

The box has nothing to do with the pedal.

The fellow in the video has taken the valves off his torch and
mounted them in a box.

He just moved his torch valves to a new location. :)

[purdy]

Yes, that box is a manifold made by carlisle. as the gr was originally a lathe burner, it was not outfitted with a built in valve manifold. The box is not a part of the pedal. Its a pretty sweet torch, it gets wicked hot.

[maui greenstone]

How would this work with the gtt triple mix? Would you add a 3rd pedal or just operate the blue oxy nob by hand. I'm invisioning for this to run my kobuki that i'ld need a rack of 9 pedals.......not that I'm gonna pull the trigger and have u make me one just yet, but hypothetically how much would the 9 pedal system cost?

[jr23]

Oh my let me guess maui U are nothing less than a dance dance revolution grand champion.

Also one more point for microchips in the brain, Making the pedal less pedal possible.

Bye the way only three purdy pedals are nessary without gtt making a 9 stud k delta you only have so many studs.

sorry blue valve is still by hand even with three pedals.

[maui greenstone]

Oh yeah, duh.... Ports= pedals. Had a though about adding little armature with 2-3 magnets that could adjust up and down to provide more flame presets. So as you push through the range of the pedal it would hold in those spots but still easily pushed through.

[B-Rye-oNeR]

well hey, it looks like the hardware you'd see on any other foot pedal you'd buy from Griffin or any other reputable company,..... how about that?

(I'll be seeing one of these next week, hopefully demoed on my mirage)

[hedcraft]

You can obtain a provisional patent pretty easily for around $250. That would allow you to discuss your invention openly without the fear of your ideas being stolen. You'd have to apply for a full patent within a year, but if you're already at the point of marketing these things, that should be plenty of time to find out if the potential market is worth the price and trouble of a patent application.

I only mention it because that would have prevented the fallout that followed.

[ALIEN!]

^ I think it's actually about $150, but yeah, good for a year, then you have to be filed for a full patent. You can send in a drawing on the back of a napkin for the provisional (seriously) but the full patents have to be very well written with good clear itemized drawings. Unfortunately, patent lawyers charge $500 per hour, that's why they generally cost $10,000 or so for many people. The actual patent filing fee is only $500, however may take up to 9 years for the patent office to get around to reviewing and hopefully approving it. The shitty part is your patent once approved is good for only 17 years and those 17 years starts on the actual filing date, instead of after approval. Worth it I guess though if its something that can make serious serious money.

The provisional also confers the right to put a "patent pending" label on your item.

[Greymatter Glass]

I like the adjustable stop....

keep in mind when working with items made for welding that most welders use acetylene, not propane. brass and stainless don't matter, but if your valves or hoses have any polymers / rubber in them you have to make sure it's safe for propane gas, as most plastics and rubber are not.

Still, I think you may be running into patent violations on this...I'd do some research before filing for patents...

[purdy]

Absolutely greymatter, no polymers besides good old ptfe. I have done alot of research on this type of valve system, and as far as i can tell these are unique. I have waited a while to put this out, and i tried my best to get my ducks in a row. I am just not in a financial position to afford the patent process, thats all.

[khan]

Patients are overrated in my opinion.

[brian falls]

green oxy safe PTFE yes?

[ALIEN!]

correct

[Icarus]

Khan

Please elaborate.

[purdy]

Yes it is oxy safe ptfe. The price tag is where it is because of the labor that goes into one of these pedals. Also, the price is comparable to other mechanical pedals on the market that are just on/off. It takes me a while to machine each part by hand, as i dont have alot of fancy machine tools. But rest assured, they are made with love. I am a perfectionist, and I wouldnt let anything leave my shop that doesn't hold up to my rigorous scrutiny. I would be happy to show it to anyone in person. Im in south jesey and im always down to kick it with glass folks. Hit me up!
