Lets Talk transitions and diffusers

[Groundjoints.com]

Hey Guys and Gals,

I am currently working on bringing in high quality transitions and diffused bushing adaptors from our robot friends in Germany. I see that the pricing for these is all over the place. How many of you use these parts and would be interested in getting reasonable priced high quality ones from moi? I'll try to put up my first poll.

[LTD]

Gimme, gimme gog! Costs are all over, I'd pay .50 for some 14/20 male&females

[Lambs Bread]

what r they?

[slinger]

yes yes and yes.

im dying to get my hands on bushings, transitions and coloured joints.

sup witht the diffusors? they like roor style or something like that?

holla at your boy.

[somberbear]

id like a few sample packs of all of the above.... then agian i been collecting joints and fittings i even have a tig welder cup thats made outta pyrex.

[LTD]

SAmple packsThat is a great idea, I'll take two.....

[timinny420]

there giveing away sample packs - i want 5 - sweet thanks adam :)

[borealisglass]

charge me for a sample pack

[Royal]

yeah please get diffusers and transition pieces. post it up when you have them.

It would be cool to see pics of what you talk about. the diffusers with a tiny hole on the bottom are very WEAK. The bottom hole should be the size of the tube for easy cleaning, and so it hits right. I buy the g on glass fittings that have the MADE IN CHINA sticker on them, because i get em for 1.25 a pop. When the german machine made equivilents come down in price, i would get them. But the german pieces are way overpriced. The quality is the same, the price is not.

Where do u get them for 1.25 and are you talkin the 14/20?

[Royal]

you can get ones that arent made in china for 1.25 if you buy a 100 i think or maybe a case.

also UST are you getting any of the blue joints in?

where?....blue joints?

[Royal]

i heard that ust was going to start carrying the cobalt joints, i have seen them around but never anywhere to buy them. hopefully he will comeback and clear it up.

[broken glass]

I get em for 1.25 from a local smoke shop, Im sure i could get it for a buck or cheaper if i bought a bunch, but i am only buying packs of 12 for 1.25 each X 12 thats for 14/20s

[Vapor Glass]

the UST joints are top quality. im looking forward to carrying them. the length of the ground part is longer on these than the other ones floating around. this makes for a better lock. i like to try the products i sell before i sell them so i know what is good and what isnt. nuff said.

[Gibsons Glassworks]

put me on the list!

[Gibsons Glassworks]

also the tools that slip into the fittings to work and hold them are good to sell also... id take one of those, ive just been sticking 2 together to holdon..

the diffusers with a tiny hole on the bottom are very WEAK. The bottom hole should be the size of the tube for easy cleaning, and so it hits right.

The bottom hole should be the same size as all the other holes. If its bigger, all the smoke comes straight through it and it doesnt diffuse anything. It has to be just as small as the rest so there is equal pressure between all of them so it diffuses equally. It may be harder to clean, but it doesnt do anything if its a big hole on the bottom.

[broken glass]

HaHaHa this is a funny old post. I buy all my stuff from adam now, and the joints are way better than the chinese ones.

Actually you are forgetting the effect of gravity. To pull smoke through the holes you have to displace water. Water is heavy. More heavy than air. The smoke will chose the path of least resistance. The heaviness of the water means that the pressure will have an easier time moving out the slits, than out the bottom. Any more than two slits on each side and you wont be using the bottom hole. Clearing and milking are different. But when you are clearing, it is only air going through so why diffuse that?? This is fact and physics, not stoner stories.

I would get diffusers if they were reasonably priced.

You might be right if you are pulling so lightly that the water in the downstem only lowers until the air can exit through the side slits and not come out the bottom, but if youre a normal person and are pulling air with any kind of force, the path of least resistance is immediately the largest hole. This is especially true in diffusers with cut slits rather than popped holes because the slits allow such a small flow of air compared to a big hole in the bottom. As soon as that vacuum of average-rip force is introduced in the chamber, the majority of the smoke will be pouring out of the large hole.

It will still bubble of course and nobody will really know the difference unless theyre taking close-up high-speed camera footage of the diffuser in action, but why use a diffuser if its not really going to diffuse?

If the holes are the same size, they all release equal smoke. If one is much bigger than the others, like in a diff. with a big hole on the bottom and slits in the sides, it will be uneven. Pretty simple.

Also, gravity and the weight of water are not the most relevant issues. The water is being pushed down by the air, not up. The most important thing is the vacuum force and the comparative area of the smoke's escape routes out of the downstem.... You made the destinction between milking and clearing and that is a good point, but even while milking, a person is sucking with much more force than water can resist against. I get your logic, but it stops short. And what if its a bub rather than a tube? Then the clearing has nothing to do with the diffuser unless youre using a diffused snorkel carb. Even then it is still subject to the same vacuum force of a hit.

Dont forget to consider all of the reality facts of the situation...since youre talking about facts and physics. Thanks for referring to my logic as stoner stories though....buddy.

[Shiny]

I was taught to make diffusers by popping five holes in a tiny bubble at the end of the downstem. Four around the sides and one on the bottom, all the same size. The one on the bottom still allows a pipecleaner to make it through so it can be cleaned rather easily AND actually function as a diffuser.

none of this really matters though unless your perspective customer understands that the diffuser theyre paying extra for only kinda works. At least the ones with slits and a big bottom hole look cool.

Im not trying to chap anyones britches by saying their diffusers dont do anything, theres always the possibility that Im wrong, Im just sharing what I believe to be obvious. And Im sharing it in a bit of an asshole kinda way because broken glass riled me up with the stoner stories bit.

My apologies for the negativity.

[broken glass]

Have you ever smoked beside a mirror, because I do to test what I make, and I stand by my claims.

The hole in my bowls is 3-4 mill, and the easiest path is the slits when firing one up. Trust me you cannot pull through the bottom hole with three slits on each side, and bowl on top. It doesnot matter how tough your lungs are. When i clear the inlet goes to 9-16 mill, and then it starts to exit the bottom.


I tell you this from trials and tribulations, not thought but experience. And didn't mean to insult you. So i appoligise, but i guess i react to your logic being similiar to stoners i meet in shops and such with rediculous ideas of how shit works.

[mer]

i just cut slits (with a tile saw) in the downstem near the bottom and fire polish. it diffuses really well. try it once and convince yourself, it's a five minute experiment.

[Shiny]

Ahhhh so another key factor is the total open area in the slits being equal or more than the open area of the bowl hole? Im beginning to believe you, maybe, as well as beginning to overrun this thread. Can you really see whether its working through all the bubbles though? Im tempted to go buy a diff stem with slits and try to see.

[boxfan willy]

I agree on the path of least resistance. I open up all my bottoms large so the customer can clean them easily. Then I perc the shit out of it. If you chug hard enough to hit the bottom hole, then your gonna puke anyway. I know this from personal experience(haha)

Wow, i shoulda read the second page before before I posted.
For real, the water is heavy enough to keep the air from the bottom hole. As soon as the air from the stem passes the first line of orifices, it will begin to release pressure in an effort to equalize. Drop the pressure a bit more by pulling more vaccum and it will hit the second round of orifices, and again begin to equalize pressure, on and on.

If you give yourself enough diffusor holes that create an equal or larger area than the opening on your mouthpiece, it makes it very difficult to rumble to the bottom. Remember, physics. Please try it on any diffused downstem to prove it to yourself. The better we make our stuff, the longer we stay in business.

[boxfan willy]

Oh and let me displace the idea that hole size doesn't matter(not related to matters of the bedroom).

Wrong, I believe.

The more surface area that you create is the more filtration and cooling that will be create by a diffused stem. Thus, smaller and more numerous holes will create the most surface area out of the smoke thus providing the most thorough filtration.

[Shiny]

youuuuuuu tuuuuuuuube has convinced me. I was totally wrong. Didnt know that volume of air could get through the slits.

[Greymatter Glass]

Air... crazy stuff, isn't it?


So FWIW, I'm selling the German style joins in both 14 and 19mm sizes, as well as short and long bushings. The German style joints are longer, and look heavier than the Chinese / American style joints.

[Galaxie Glass]

Doug, whats r the prices ? never used em before...Quality ?

[kipton illuzion]

the china fittings suck!!!! adams the man his fittings r way nice i jut got a bunch check em all!!!!

[kipton illuzion]

he got all sizes and wall thickness 2 made w german glass (schott)
very nice i like!!!!!

[nickglassdood]

i love my lo-pro or bushing adapator on my lu i reallly want a 50x9 illadelph but dood if croke so make joints i relly think the chiese ones are thinner or sumtin?? what you guys think?????

[mer]

sorry dood, that was even a little hard for me to decipher and i usually catch your drift.

[bc]

I'll translate.

Dood likes the low profile transitions on his tube; He really would like an illadelph 50x9mm; he brakes alot of the cheaper gong fittings. Are the chinese gong fittings thinner than the German ones? What do you guys think.

my answer: Get the illadelph, they use 26mm hvy females with 'German' low profiles. Way better than those gong fittings on every so cal company tube...

atleast that's my stab at it.

The bottom hole should be the same size as all the other holes. If its bigger, all the smoke comes straight through it and it doesnt diffuse anything. It has to be just as small as the rest so there is equal pressure between all of them so it diffuses equally. It may be harder to clean, but it doesnt do anything if its a big hole on the bottom.

A good solvent can clean anything, no matter how its shaped. Try some 99% isopropyl (also known as rubbing alcohol) with some coarse salt or get an actual pipe/bong cleaner like 421 - it does wonders. (I know this is way off subject for the topic, sorry, lol).

Also, I'd love to see some colored joints, or nicely pre-made diffusers (I tried making one the other day and it looked like total crap on a stick :tongue2:), since I'm to noobish to make my own atm, lol. If you do get this stuff in, I'd definitely be interested in picking some up.
