Devo Glad you asked that question. I have had a couple emails asking the same question. Being the great businessman that I am, I never even thought about this happening as a result of changing the heatsink. That's how stupid I can be. My main problem currently is I cannot get the old heatport...

CD asked me to send him some tips, then abruptly changed his mind over the lead issue which is not an issue now. His choice to make only PD stems is up to him and fine with me. Believe me, I know what it is like to have lots of work on the table, then get asked to do more. I applaud you CD. You...

As mentioned over on the "is brass safe" thread last night, as of yesterday, I have changed my heatport construction so that all brass used in the AZ/MZ is lead free according to RoHS standards. I now use a stack of brass washers for the heatsink portion of the Zap. They are RoHS washers...

OK, as of today Rick says everything in the vapor path of the AZ/MZ is "lead free" according to RoHS standards or however it is correctly stated. Well, not everything. There is a dab of Myrtlewood, not RoHS but lead free, that the air whisks by. But the rest has the letters now. I changed my...

You did just fine obelisk. Do not apologize for anything. We have all learned alot. I always knew brass has lead in it. My explanation as to why it was still safe still stands for now. I have learned everything but that heatsink will not test positive for leachable lead. Now we need some...

The answer to question one is yes. The air goes down through the six holes in the top plate then down around the brass heatsink(that tested positive) and then up through the center tube, past the heater and into the stem tip contents. I think 2 is also relevant. Your Zap is a goner now?

My experience is you will destroy the unit if you try to remove the heatport, You can get the ring out but the heatport will not come out because the wood has changed shape due to the heat. The brass will bend/crimp if you try to grab it with pliers. If you want to test the liner, go get a 3/4 "...

Tom said "Your puddle of molten brass has less Lead than it did before. Didn't you get it, that vapor contains Lead. And the puddle now contains less Lead." Oh really? At what temperature does lead vaporize? I thought you were just about the facts, Mam. The brass alloy will melt way before the...

My question was not about solder Tom, it was about brass alloy with lead in the alloy. Your link was about lead, straight lead. Would you answer the question directly please. How does the lead in the brass alloy we use get to a human? Your constant attention to the subject certainly implies...

Tom says: "Let's get something straight, one more fucking time, I have never said the Aromazap or Myrtlezap were un-safe. I have never said you will get Lead poisoning from using one of these products." You sure do thoroughly imply AZ/MZ is unsafe quite often. I would say most folks here would...

Ed So sorry I did not call last weekend. My youngest son(33) came up for an unexpected visit and we had a great time with him, other son and grandkids. I totally spaced anything having to do with Zapville. I was going to call this AM but being Easter and all, thought I would wait til later in...

I see the Mother and Child. I also see three. I love three. Father,Son and Mother? I always saw three in that piece on that side. The other 'front' is interesting too. BTW, mom, that is some of the 30-40 year stored inside Myrtlewood. It is so sweet to work with. So hard yet so workable. OMG...

Thanks for doing the test obelisk. Very interesting results in light of what we heard earlier. My response to all this is posted on my thread.

First, thank you for doing the lead test that you reported on the "is brass safe thread" obelisk. Just saw it. now my answer to the folks over there. Next, an apology for the lateness of this reply that I promised yesterday. We had a fun day yesterday with a Chinese dinner included and got home...

So nice to see "The Born Again Brass is Unsafe" thread take shape as it was always intended when reopened, even though there is "no hidden agenda" says VTAC. I will respond to specific allegations about AZ/MZ and me in my thread where it belongs. I must say I still do not copy/paste Toms posts...

I prefer to use a 3/4 copper pipe bushing or a socket that will fit in the top hole and rest over the internal retaining ring that holds the heatport in place. Put the Zap on a firm surface, bushing or socket over the ring and give the bushing a good rap with a hammer a time or two. I have also...

obelisk If you put the Zap on a flat surface you can put a stem in the heatport and push down firmly to re-seat the top clip that holds the heatport screen in place. You can push hard as there is another clip under the screen that rests against a hidden crimp in the heatport tube so it will not...

We will not be spending any money for tests to prove the negative some are asking for. As always, if you have any safety concerns about AZ/MZ, just do not buy one. Petty simple really. I do believe the periodic attempts on FC to convince others of the same(brass is unsafe) are done for a reason...

Gee whiz lwien, you might have asked a bit more about the heat exchanger before getting so picky. The tubing NOT in question is pressed through the middle of the brass heat sink(sorry,different supplier), after I drill a hole through the middle of the heatsink. So the heat exchanger is "lined"...

OK crew. I must say, VTAC, you prompted me to do something I have not yet done because I have always felt the same way about this issue. AZ/MZ is safe and I know it. A bit presumptuous but what I knew. So I Email K&S engineering who makes the brass I have used for almost ten years. Wow, he gets...
