hey one of the basic flaws of they single wire design and is that one of the tungstens takes more heat than the other, using AC it will share the work load, but will realistically need a continuous high frequency to keep the arc going between the crossover. but you already know that. soo..

Scalli, what size gap are you running on the tungstens, and whay gas are you running?

If you can I want you to try and run the entire gun off the mig power supply. Run normal bare wire as not to waste your precious fluxcore. Run WAY up in the amprage in the about 250ish area around 26-27 load volts maybe a wee bit more to get the wire to spray. First test it to see if your in spray clamp a ground on a piece of scrap and letter go(with elcetrode out or not connected) This will also allow you to tune your WFS AMP, just like a MIG. Now that your are closely tuned, connect a neg on both electrodes and run the wire positive, this will keep most of the heat off the tungstens and should produce a better spray pattern as it should make finer droplets.

Scalliwag

Yep, I mentioned a few posts back that I am tuning the gun on scrap Also I am running the whole process off the MIG power supply. The AC was really funky even on high frequency so I gave up on the pretty quickly on it.
But I got the tungstens working very well. I did an off the wall "trick" on the positive side which is the gravy to the whole idea at this point.
If and when it is actually on the market or at least in a protected status I'll cover that and you are going to bust a gut when you see how I did this. It will make perfect sense to you.

Hans

youd better start on some patent paperwork, seriously...

Scalliwag

I have looked into patents before and with everything involved it is easier to sign confidentiality and non-disclosure contracts and sell the idea. The contracts are legally binding and with you guys I would have plenty of witnesses if there was ever any problems that came up for me to prove conceptual time lines.
The most practical reason for selling the idea for me is a lot less footwork and much quicker to get money for it. I would rather spend my time and energy playing with equipment than figuring out patent proccesses. I'm not a businessman and legal **** makes me dizzy.
I filled out a form and sent it off last week for a "Inventor Request for USPTO Disclosure Document Program" http://www.freepatentforms.com/ddp.htm which is a little redundant since I have dated proof here on the forum. Believe it or not this discussion would carry some legal weight.
Here is a great site for patent forms http://www.freepatentforms.com

SnowmanSteiner

^ That and start looking at getting patents for your other ideas that you have laid out so far too.

**** try and get insurance for a mobile welding rig, I'm still looking...
Back in welding school there was a story that made me sick
Guy I know gets out of school then buys a truck to set up a mobile welding rig as a DBA. After a few months is doing extremely well and is going out a job, 16 year old driver looses control cross yellow lines and was killed. Father of said teenager sues the guy and wins, whom looses truck, business, house and loads of money
before we go there, YES it is a horrible thing that the driver was killed, but cannot see how the welder was at fault, and deserved to be punished as so.

Go America... the entire Judical system needs some help IMO

Of the short if he had a little bit of Business sense he would have filled to become a subchapter S corp and not lost his money and house, just truck and 'business' but it is sad how much tape there is to protect yourself.

Scalliwag

I have a friend that his parents sold a car and the guy that bought it did not get the title transferred. This dick got drunk and wiped out some guys wife and daughter. To make a long story short they lost everything over a title not being tranferred.
So if you ever sell a car here in Texas you better tear that thing off the top and pay $5 because it is the only thing to protect your ***.

rotorbrain

hey scalli, a friend of mine is in the process of building a 3rd gen motor and may wanna look into this. . . hell be building a few 1st gen motors as well. his name is david garfinkle. . . he gets things done quickly and is VERY meticulous in his work. if he were to build an engine using your "stuff", i am sure youd be satisfied with his results as a test mule. his name is david garfinkle. . . you may have read about him in the 3rd gen area. anyways, if youd like to contact him (he doesnt get on the internet much), his phone number is (615)893-4469.

if you want him to contact you, give me your info and ill have him call you. hes ALWAYS interested in some cool rotary products.

also, ill be piecing together a motor soon. . . probably not as soon as YOU like. . . and i have a set of rotorhousings that would like to be reworked. i was planning on buying a used 3rd gen motor so i could complete all of this later. so, if its open to us lackies (sp?), id like to be "in".

paul

btw, id like to vote scalliwag as totalitarian dictatorship of the rotary world for this innovative research. . . he is an asset to the community at the largest rate possible.

Scalliwag

Wow, a totalitarian dictatorship? Heck I am not even in the top 1000 on that list of worthy notables. Heck the people that Marc works for that have actually brought resurfacing to a reality and to the market come to mind. Paul Yaw, David Atkins, Moller (the car/plane), Rob at Pineapple, BanzaiToyota, a whole ton of folks in Australia and NZ, Racing Beat folks, Mazdatrix, and the list just goes on and on.
I am probably just the only one that piddle around and share most of my thoughts and ideas on the forum. For some people this is their livelihood and they have invested far more than I ever have or probably ever will.

Since I have a day job that pays the bills and keeps me fat I think I am understandibly less guarded than the serious players. When I do get the opportunity to talk to one of the true innovators I definately am the one at the benefitting end of the meeting.

I wish I had a timeline to set on test spraying. It will be as soon as the gun is adjusted and somewhere in between all the eBay and forum orders. So whomever does get involved in testing has to just happen to be ready in the same time frame as I am ready to start.
We will spray and finish the first set and test them in the shop. While that motor is doing it's test period and proving it is looking good will be the period I am making the push for volunteers.

Thinking of Marc and his ceramet and thermal barrier coatings...

Yamaguchi 2nd gen bible states in 1985 Mazda made the MX-03 enginnering concept car that was actually a running prototype. Awsome AWD 3 rotor w/ four wheel steering and Cd of just .25.

Anyways, Mazda made the rotors out of aluminum w/ steel inserts for the seals and ceramic coated them. They also used a ceramic insert in the rotor housing instead of steel. Apex seals were ceramic. They planned ceramic side housings, but they were just steel (probably flame sprayed w/ something since they started that in 1965) in the prototype.

Because the ceramic engine ran so much hotter (more efficient) they had to use gas seal springs silicon treated molybdenum alloy and metal bellow o-rings for the oil control seals.

These ceramic coated engines running on gas are going to be HELL on seals and springs aren't they?

couturemarc

Excellent point!! Just keep in mind that products such as Viton (tm) were only invented in the 70's and even today's newest forms of Viton far out perform those versions of the 70's and 80's.

In addition, today's ceramics and variations such as cermet didn't exist 40 years ago. Even the materials used in the 787B and other vehicles of the early 90's have been further developed to provide mechanical properties that were unheard of 15 years ago.

To keep this short, there are no sealing or material failure's associated with using our cermet and thermal barrier engine components, these have been tested. The incresed thermal efficiency of the engine results in slightly raised chamber temps that are still well within the operating tempertures of today's o-rings and seals.

Scalliwag

Have any of you guys ever made a vortex tube?

Hans

no, but I know what they do...what do you have up your sleeve

Scalliwag

Wouldn't they be the perfect electrode collet?

Hans

aye, indeed it would be. man I bet you love those Goldberg machines...

Whats the story on the air compressor. I bet a dollar the bore is outta round, and loosing compression around rings. after that I bet a manifold crack or some fitting lost its teflon sealant.

Scalliwag

The top ring on the small piston had a carbon seize. So I popped the rings and cleaned the grooves and put it back together. But after firing it up I noticed that the unloader valve had a constant stream of air pressure coming from the relief port. I took it part and the actuator is trashed. So I called the local compressor shop and they have a new one waiting on the counter for me for $26

On the vortex tube idea I cannot take credit for that. The guy that owns the welding supply I use gave me that idea. He is a really sharp cookie and always giving me incredible deals on stuff. For example he sold me a new 15' 400 AMP MIG gun with a 1/16" liner for $125 awhile back. He sold me the 3/16" x 7" thoriated tungstens for $1.50 each
I had told him about my dilemna some time back about needing a good way to cool electrodes and avoid using argon as the sole propellant.
So he had some time to think about this and then he remembered that he had a similar situation at one time where a customer wanted to run an insane amount of amperage in a similar situation.
He said they bought a commercially made vortex tube and converted it to an electrode collet and that it was quite the ****
So now I want to implement that into the gun as well. The colder I can keep the electrodes the hotter I can run the amperage. The higher I can run the amperage (to a point) the finer I can atomize the spray. The finer I can atomize the spray the better I can control the build.

Ultimately if I can get an even enough spray I can keep the build thickness to a minimum so it does not kick my *** as bad on the finishing.

banzaitoyota

I have a seal that will hold up to anything you can throw at it. Trouble is the cost

SnowmanSteiner

Proposedly I'll be doing some testing for Banzai in a couple years once I get my new motor put together. I'll make sure I test it's ability under a lot of pressure. And knowing banzai I'm pretty damn sure it's gonna hold up without a problem. Now the relation; Scalli and Banzai's ideas are generally of the same direction. Stuff that'll hold up to the test of time and power capabilities.

- Steiner

Scalliwag

I think Banzai and us are both nuts. He is probably just like me in that I spend WAY too much time reinventing wheels. When I'm not physically working on stuff then at least a good 60% of the rest of my waking hours I am thinking about it.
Banzai has some really neat stuff. I have what is left of a roll of Banzaitape here on my desk I am always showing that **** off to my buddies that come to the shop

Oh wow, it's Thanksgiving guys Have a great one. I will update you on my progress later. Let me say that the compressor is running great now.

iTrader: (3)

sweet...progress! wtf is Banzaitape?

Scalliwag

Well it really isn't tape. It isn't sticky. But when you wrap something with it (correctly) it is as though it fuses to itself. It is silicone based so it is non-conductive and waterproof.
John can explain it much better than me. He messes with all sorts of aerospace stuff. (lucky bosstard!)
While some of the materials like the side seals are expensive to make due to material costs, he always makes extremely impressive stuff. Some of the materials that may be expensive now may at some point either come down in price or he may find a surplus source.
But this "tape" as I call it is great for wiring harnesses and other applications where you want a great look, feel, and permanent solution.
Here is a link to the post where I first found out about it with a good explaiation in his words.

http://www.vintagerotaries.com/FORUM...opic.php?p=284

SnowmanSteiner

Yup, the "tape" is awesome, I will also be using it to wrap my harness once it I install it. I don't get the chance to meet up with Banzai as much as I would like to when I'm home, but when I do, I usually pick his brain for all it's worth, well at least what I understand and what he can explain to me. That and I pick his brain a lot online. Good man he is.

You're talking about the self galvanizing tape. We used that in the Marines to repair aircfaft/test bench wire harnesses. The government pays about $150 per role.

banzaitoyota

BanzaiWrap is a SELF-VULCANIZING silicone harness wrap. It is heat resistant to 500º F. I've used it for harness wrap, masking when powder coating, repairing the cracked overflow tube in the toilet. Its good stuff. Go to my website to order some

self-vulcanizing. Anyhow if it's good enough for mutimillion dollar fighter jets you should be pretty comfortable using it in your car. It's actually very easy to remove compared to electrical tape because there is no glue or residue to deal with, just pull out a razor blade and go to town.
