I got one of those IP gauges from eBay and it was off substantially enough for me to hassle with returning it for an exchange. The first one arrived quickly, but the second one took it's sweet time getting here, and we're both in California. The second gauge is accurate enough for me, but has a crack in the plastic lense. Very handy, though.

get yourself an oil-filled type of gauge in the correct pressure range.
it will have a flexible barrier and oil protecting the internals on the ambient side

Hi Luis, I have some extra Co2 cartridges for SEAhunt buoys if you need some. Great diving with you last summer. Jerry aka someone saw the Kemp's Cow!!!!!!!

Hi Jerry
Thanks for the offer, I appreciate it, but I think you got me confused with Nemrod. He was the one with the SEAhunt buoys.
It was great diving with you and all the other vintage divers at Wazee. Thanks for letting me try your Farallon scooter. It has been 30 years since I used one of those.

I will have an update on my nozzle design progress soon. This will include pictures of a couple of trashed DA nozzles that I cut in half in order to take some internal dimensions. I am almost done with a final version of the drawings.
As I suspected, the bottom of the nozzle was fabricated by pressing a washer in. The rings at the bottom are the deform metal to hold the washer in place. The hole in the washer provides the guide for the pin holder.
I have also been pursuing a couple of quotes for a prototype. Getting a prototype machined and tested is in my opinion the most important step.
I talked to another machine shop today. They promised me a quote by Wednesday.

Luis, are there any developments on a quote for the prototype? Consider me a confirmed order for when you go in to production.

I still need to build one prototype to make sure my dimensions are correct and the first stage functions properly. I have only gotten one quote from a true commercial / industrial machine shop and it was astronomical for the prototype ($275 or less). He said he could probably do it for less but wouldn’t commit. He also said that the second one and any production would be a fraction of that. Well I can’t afford that into a prototype. I am hoping less than $100 for the prototype and maybe $50 to $80 for small production. I may be totally of. The drawing of the part is finished but proper dimensioning with tolerances and notes need my attention. I will be glad to share a copy. As soon as I clean up my dimensioning I may ask on the message board for assistance with quotes. I already asked Buzz if he can get me a quote. He is going to try. And Creed also offered to get me some quotes from machine shops in Kansas. I still whish I could find a local old retired machinist like I have known in other states were I lived. I could take them an unfinished sketch / drawing, we would discus the easiest way for them to fabricate it and in a few days I would have a part perfect for the application. I am sorry this project is not moving faster. I can’t use too much diving as an excuse anymore. I will try to post an updated drawing soon (hopefully this week). I also hope to post some pictures of the two DA Aqua Master Nozzles I cut in half, in order to take some dimensions of the lower chamber.

Here are some pictures of the DA Aqua Master nozzles. Notice the bottom chamber with the pressed in washer. The Royal is about 1/8" longer, the inside diameter has a small step to a smaller diameter bore (from 0.50” to a 0.46” ID near the bottom), and the volcano orifice has a larger diameter (0.12” ID). Actually, I measured three DA nozzles and all three had different volcano orifice inside diameters. I don’t have the notes with me, but what I recall they were: 0.109”, 0.098”, and 0.089”. I just updated the mechanical drawing to incorporate some changes to make it easier and cheaper to machine. I will be posting it soon.

That's not a bad price for a proto type.....I'd expect they'd cost around $500 or better for one, and that's from a CnC machine shop.......make a deal for 3 or more, with the understanding that if the first one or two need to be tweeked after machining they will make the changes at no cost.........it might be cheaper all around.

The modified nozzle should be big enough to hold at least 1 mothball.

Do you have problems with moths in your regulators?

That's spooky! Sounds like something out of "Silence of the Lambs"

It puts the neoprene in the basket!
Sorry, a little Silence of the Lambs joke, for those who have no idea what I just said.
