Anyone looking for a color match for the old HW's I found some "Dupli-Color" BGM0533 "Bahama Blue Metallic" (22 WA 9656) While not perfect it's close enough because it's satin finish and small-flake-metallic. There may be an even better match, but again, this was close enough for me.

Phil and I had a meet-up at Steele's today--very, very pleasant just to hang out with him scouring the shop for old funky parts!  I found most of an Airflo second stage, just missing the exhaust-tee, which I had at home  Images to come, but now I have one: oh and Jim said he has a first stage somewhere... Thanks for the nice day my friend! JB |

Here is what the OEM-Healthways tilt-valve and spring looks like for reference:  JB |

OK, so here is Phil's spring on the left, and the OEM on the right:  The base is off by just the slightest bit so it needs to gradually worked in; I'm not complaining in the very least because it works perfectly! Thanks again my friend! JB |

I should put my spring making pics here as well. They're on the NED single hoser thread I think.... I made these after having the tilt valve and spring sproing across my garage as I unthreaded the hose walking toward my workbench. Didn't expect it to do that.... After sweeping and cleaning and crawling around on hands and knees for a long time I found the tilt valve and a spring. Not the RIGHT spring, though. Naturally, I bought a Sportsways tilter on eBay just for the spring  (SW made the NED). So, of course, now I have another perfectly good regulator with no spring, and I'm back to where I started. Need a spring! Am I going to keep going in circles here? No. I do what JB would do. I learn to make springs! Here's my spring making thingy. I call it the Spring Makin' Thingy. 
It gets chucked up in the lathe and the end of the wire is stuck through the little hole in the end you can't see. Then, I turn the chuck of the lathe by hand and tension and guide the wire by hand as it winds around the Thingy. Somehow, the springs come out right. Mos'ly. The two springs shown are a paper clip spring, and an uncoiled pen spring recoiled on the Thingy. They were my #1 and #2 attempts. EDIT: The pictured springs were practice attempts to see if my Thingy would work at all, and never meant to be used. |

Now, Phil, you've got to make one out of stainless steel.  John |

The two springs shown are a paper clip spring, and an uncoiled pen spring recoiled on the Thingy. They were my #1 and #2 attempts. Thats a good idea.........but be careful on the type wire you use. Different OD's of wire and material (such as stainless or music wire) along with length, ID/OD, number of coils of the spring you make, can give you different rates and loads from the original you are trying to replace. I learned a lot about how springs function designing back when....it is enough to make ones hair crawl.........two springs, identical to the eye can give totally different rates and loads...................rate is how soft or hard the effort of the spring compresses or expands (depending on the kind of spring)......load is really the static load at a given point in compression. (ie: height of the spring under duress or load) Will be interesting to see your efforts for the Tekna. |

Now, Phil, you've got to make one out of stainless steel. John I made a few out of music wire. They'll do. The problem isn't tension or load so much as centering. The cone shape keeps the tilt valve centered on the seat. I measured the od and duplicated the .020 wire in the NED. |

I was thinking that corrosion would be a problem, but then remembered that these springs are on the upstream side, inside the regulator and not so much subject to external water.

Eventually I will be making a manometer to see how these go up against modern regs and compared cracking efforts: this will also be a good test to see how these springs differ  I have a super floppy original HW diaphragm that I put into my "Diver Dick" reg, it just kinda slops itself over the tilt-valve like a wet rag, then I will try the 1970's all rubber, and the blue silicone...

Phil,
Your spring-making is shown on this page of this Healthways thread. Look at the preceding posts here.
