Discontinued Purple-Days Vaporizer

[Master Haze]

Hi everyone. First post but I've been lurking for the last month. I got an Extreme about a month ago and it was love at first toke. The only down side I found was that the Extreme doesn't work well for me when I try to put in just a small amount. Since I've sworn off smoking, I started looking for another vaporizer that's strong point is efficiency. After reading through this site, I decided that the PD is what I'm looking for.

I've had my PD for 5 days and I mostly like it but I'm still having some trouble with it. I only get a really good hit about 1 in 2 or 3 tries. The problem I think I'm having is getting the end of the wand to mate squarely with the heating tube. The wand diameter is almost the same size as the inner diameter of the heating tube, but just a bit bigger. I don't know if it's because the wand end is only slightly bigger than the hole or because the face of the heating tube isn't perfectly flat - but I find that I'm consistently adjusting the wand position during a hit to try find the sweet spot where the wand is square against the heating tube and isn't letting outside air in.

I can tell when I find that point because the draw becomes slower and more "narrow" as others have described. But finding the right position seems like an exercise most of the time.

Is the end of the wand supposed to insert INTO the heating tube? I'm guessing it isn't since mine doesn't fit in - but it seems like it would be a better design if the end of wand fit into the tube about an 1/8 or 1/4 inch and then rested on a lip. That would provide a positive engagement.

Does the end of the wand sit squarely on the face of the heating tube? Usually, I'm sliding the wand around slightly during the first half of the hit while I try to get it to seat squarely on the face of the heating tube. Anyone else having that problem?

Given that this is my first post, let me assure you that I'm not a troll and I'm commited to getting to a point where I get a good hit everytime from my PD. There's a lot I do like about my PD. The piece itself is very attractive and I've gotten some very good hits from it. But, apparently I need to improve my technique. Hopefully, you all can help me out.

Later, MH

Yes, yes, yes - it slides in with a little room to spare. Mine slides easily and rests on the crossbar. It sounds like your tube is oversized - have you tried your other tubes?

I recall someone else here with a tube that didn't quite fit as well...I'm sure Tom will chime in...

Once you get this issue sorted, you'll find a major difference, let me assure you. I can't imagine having to try and hold the tube square to the heating tube.

High master Haze welcome to FC.

yes the PD tube is designed to slide all the way into the heat exchanger and rest on the cross bar. There should be a small amount of play in-that the tube will move around once its mated to heat exchanger but it should go all the way in until it kinda 'clicks' against the cross bar and can't go anymore. I generally turn mine while taking a hit. I dunno if it does anything but it allows the bowl to spin around in the heat exchanger enabling a full cook

You should typically get 2-3 nice hits and then a diminishing return from there. I don't like to push it past 3 hits normally (unless the video camera is rolling LOL) and save the ABV duff for a re-vap at a higher temp.

edit: reading your post again MH ... it def seems you have a faulty tube so try another one of the 3 you should have got with your PD. The steel bowl end of the tube MUST be inserted into the heat exchanger for it to work properly.

so i just went to my hardware store and came back with some silicon tubing...the tubes are kinda small tho...they fit air tight into the inside diameter...cools off the hit a little bit but i wish they sold larger tubing.....although i did have some clear vinyl tubing that fit over the bowl stem for the PD and it tasted gnar gross ahh maybe ill buy the 10 ft. of silicon tygoon tubing at that one tubing store but im not sure...

all in all the hits ar a lil better but still clogged...and i have cleaned my stem by now

 

[Master Haze]

Haha - that explains a lot!!! No wonder I've been having so much trouble. None of the 3 wands fit into the heat exchanger. It may be that I just need to work it a bit with a round file until the wands will fit. But I'm going to wait to hear from Tom before attempting any mods myself.

Thanks bongoman and vaporcloud for the quick response! I'm reallly pumped now.

What do you mean by clogged? Do you mean the airflow is restricted?

This was the one biggest things for me to get over when I got my PD was the restricted airflow ... and I still make the mistake of overloading a bowl therefore making it to hard to draw on. This IMO is part of the design and one that can't really be modifyied for good reason. The small bowl and restricted airflow are what makes the PD so efficient and gives it that high vapor to air ratio.

One thing I have always wondered tho was how well it would work if pushed up a volt and a half. I did put this to Tom and in his experience the hits were too hot and over cooked the herb when you went above 12 volts. I'm thinking if you did the StoneMonkey tubing mod, ran it through a bong, at 13 volts this puppy would hit harder than anything else out there yet retain its efficiency.

make different models! low voltage and high voltage

Cool idea but I keep thinking the short vapor path is a big part of the PD's efficiency factor. Introducing tubing and water would have to increase the vapor loss at least a bit, maybe significantly (as great as the PD hits, it is a small bowl). Increasing the voltage could be good for taking really hard hits, but it would result in scorching at slower speeds, something not possible (afaik) with the current design, which also is quite forgiving in regards to hit speed imo. Sorry if it seems like I'm shooting down your idea as a bad one, not my intention, It'd be cool to see as an experimental version, if that's easy to do. It just seems like the current PD voltage is tuned to perfection-- I'm still constantly amazed how well it's calibrated. Funny that the seemingly low tech, unassuming little piece of wood does it better than many of the big digital jobs.

Master Haze. That's strange that all of your tubes would be too big... Maybe the heat exchange tube is too small? The bowls do have a small lip near the mid way point (where the screen is) that can get 'snagged' on the edge of the heat exchanger, preventing the bowl from being fully inserted. However this is easy to see and prevent so probably not your issue.

One thing about the PD and really any vape, direct draw especially, is it's kind of like an musical instrument-- You can usually get some sounds out of it right away but it takes a lot of practice to really master it. I'm still improving on my PD technique after 3 months of daily use.

Time for another pinch.

hmm i think i have some spare silicone tubing from aquarium pumps, im gonna rig it into my little bong if it fits
the moister vapor will be welcome

Make sure you clean that shit. You don't want fish bacteria in your lungs.

Bro ... most of the time my ideas are total crap ... and the 13v thing more than likely sits in that basket I'm nicely vaked after 3 PD tubes. I'll go and have another couple soon ... and then in an hour or so I'll crank up the Vaporite to put out the lights. Now if only the PD could ... nah its fucken perfect

Hello Master Haze and welcome to the family.

Sorry to hear you having trouble.

Yes, there is something wrong, and it can be fixed pretty easy by me (or you if you feel like it).

The Heat exchanger tube is cut from a longer length of tubing. When we cut them they get a bit of an inward flair, We ream that inward flair and de-burr the inside diameter, trying to maintain as tight a fit as we can, Seems yours was left too tight.

There are several things we can do. We can replace the unit. We can repair the unit. Or you can make the repair. A small file would work, or even a bit of rolled sandpaper will widen the top of the heat exchanger hole just a little. It won't take much to get it to mate up, maybe a thousandth or two at most.

If you have any difficulty or feel this is beyond your ability we will gladly make it right for you. Just let us know... we want you happy. Again, sorry for the difficulty.

I find that I'm consistently adjusting the wand position during a hit to try find the sweet spot where the wand is square against the heating tube and isn't letting outside air in.

Once you get your 'tube mating' issue solved there'll be some play when a tube is inserted in the exchanger. It should not be a tight fit. At this point, "letting outside air in" is what you want. As you draw on the tube, you're drawing air into the exchanger from above.

As a twenty years daily mj smoker, I no longer have the respiratory system as before.

When I began to vaporize, for about four months, I realized vaporizing was much smoother and an apparently healthier way to use than by smoking.

But when vaping for several minutes, I felt my lungs tired due to the restrict airflow on the unit.
Im talking about a crapy vapir oxygen, the only vaporizer I own, and its airflow kind.
When smoking, the effort on sucking is low, compared to vaporizing from fairly restrict airflow of my vaporizer.

I know the benefits from vaporizing against smoking mj.
But these benefits dont come without the extra effort on sucking.
Maybe my 20 years smoking (only mj) or the increasing effort by sucking when vaporizing makes me feel unconfortable if hitting several minutes. I dont know.

BTW, Ive read some guys here talking about the restrict airflow on the PD too, when i think:
Wont that extra effort into sucking hard on a restricted airflow, over the time, mistreat my respiratory system?

What do you think?

 

[Purple-Days]

Vapor tip to heat exchanger tube mating should be a close tolerance but not crittical. We try to keep it as close as we can but a little play is needed so mating isn't difficult.

Air enters through the two holes and goes through the heat xchanger before comming back up through the HE tube. Very little air slips past the Tip / HE Tube junction.

Master Haze, if you have any difficulty let me know.

I knew I had a couple of HEs that were tight and was watching for them, but this one must have got past me. I'm embarassed.

Yes VC you can get a bit higher temp with 13 volts but the 13V transformer is rather difficult to find. It does make a harsher vapor. I don't think it is worth doing. I have a 13V and don't use it. In the car you will get a higher than 12V voltage from the alternator and get hotter hits, but the moving air in the car seems to offset the voltage increase to some extent.

Anyone looking for Tygon super flex tubing, it's $1.98 a foot for 3/8" ID (stretch over the 1/2" vapor tube) here...

IMO added tubing adds air to the mix.

You can pack the PD too tight and restrict airflow, and at best it's not nearly as free flowing as a standard size whip vape, but you don't have to suck hard and make it a real chore. You can 'puff' with your mouth and not involve your lungs in deep pulls. You can also hit the tube with a slightly open mouth and pull in some outside air for a more comfortable hit. I don't really remember anyone having this as a big issue. Hopefully it won't be one for you either.

If this were a concern of mine I would look into the Extreme or something else that has whip assisted hit capability...either that or just bag it with a 'cano or herbalaire.

So it's possible for me to try a 13V? I have a shit ton of random power adapters around my house... I guarantee their is a 13v around. It won't negatively affect the unit? Like blow a fuse or something???

Might just be kinda fun to try....

As for the restricted airflow, it really isn't a problem. My analogy is kinda like drinking a very thick milkshake.... Except it's sugar free and gets you high.

 

[Purple-Days]

Yeah, if you have a 13Volt @ 1000mA and the right plug hook it up, no problem but don't go higher then that. Like I said 13V is harsher. I think once you are in the vapor zone, going higher just releases more of the stuff you are trying to avoid.

 

[SpiralArchitect]

Alrighty, thanks Tom! I'll keep my eyes peeled, I know their is one around here.... I'll have to double check everything just to make sure.

I just like to experiment, I'm sure you know how it is -- being an inventor and all.

edit//
Know where to buy any online? Almost all of mine are either way over 13v or ~5v... I've been looking online, they are very cheap. but I can't find anything specifically 13 Volt @ 1000mA . Example. Another.

 

[vaporcloud]

arrrrgggg its a Conspiracy. hahaha just joking ... I've looked around too and 13v @ 1A adapaters are rare. And like Spiral I too like to experiment and it has nothing to do with being unsatisfied by the product.

Looking forward to pics of AoZs bong setup

 

[Master Haze]

Hey Tom - thanks for the reply. I sent you an email.

Ah hah, that's how the air travels, nice. And here I was thinking that the air was coming in through the tube junction.

I'm loving my new PD by the way Tom - am running it about 10 hours a day and finding it very easy & convenient to use. Every aspect of it is just sweet - the looks, the temperature, the bowl size etc is spot on.

 

[SpiralArchitect]

Yeah, this thing just becomes more and more enjoyable as the days pass..... Mine has only been off for about a total of an hour (going to friends house and back) since I got it!

right on

i personally find that one bowl will get me where i want to be high-wise if im going to do something, 2 will incapacitate me, and 3 will start to become pretty psychedelic, but for that i think ill need to get some sativa, as the strain i have right now puts me to sleep before i can really get much done in meditation
its somewhat more difficult for me to control my dosage and use then it was way back 6 months ago, thats prolly many factors though, plus the fact that vaping doesnt destroy me as much as smoking, very hard to explain, but vaping is just plain better, the difference in the high is negligable, but somehow, its a vast improvement, certainly not what i was expecting, but not an unwelcome suprise

the feature on the pd that i think is really cool is the stainless steel bowl, because, as i was thinking earlier, it adds an extra element of conduction that heats the herb through more evenly, probably a part of the reason the pd gets so much out of so little herb, as one of these bowls is about half a bowl i would pack in my pipe
