the penny whistle experiment

[Mr.Spooky]

plates are mounted!!! woo hoooo

[Kentucky shinner]

I am anxious to see how this works out for ya. Looks great. How are you going to seal the cross tube?

[Mr.Spooky]

shit . theres another problem.. i guess that the 1/2" coming into the T would fill up,,, is that what you were talking about.....
guess i need to plug that somehow.
thanks for the observation.

if joe did it, he must of had a reason,,,

The reason to have the ring is to form a kind of cup to maintain the reflux while moments that the vapor cycles.

That makes sure that you always have a stable run.

It doesn’t matter if you have perforated or bubbled plates, neither the column size.

[Mr.Spooky]

oooohhhh ,, i see . thats a nice looking plate by the way!
so on a 4" plate (10cm) do you think that it would be bennificial to weld on a ring? i was thinking of a small guage wire, maby 1/8" (3mm) ? or do the bennifits only apply to a continious running big scale still?
thanks

[rednose]

To make it work correctly you want to go a little (3 mm or so) higher than your downcomers.

[Mr.Spooky]

ok, i understand.
when i make my 2 plate inscert, i might try that.
thanks

looking awesome!

[Mr.Spooky]

thanks condensificator.. hows that 3" internal TEE LM/VM coming??

[condensificator]

just got back from a trip and have to catch up on some work before i can fuck with it again...but i didn't stop thinking about it the whole time. got some little tweaks and stuff that i figgered out while away. all the rest of the stuff i need to finish showed up while i was gone, and i am TORTURED having to sit in the shop and not work on it!

Mr. Joe, Mr. Spooky et al, I've one quick question concerning Joe's bubble cap plate fabrication. I see from another post that you used a weir (ring wall) around each plate to keep the condensate flowing down the downcomers only. My question to you is: How do you ensure that the vapor doesn't bypass your bubble plate caps all together i.e., flow up between the column wall and the edge of the plate and bypass the condensate all together.

Though I'm a big reader of this forum, I'm not much of comment writer so please know that like many others here your work is impressive. I just can't seem to find the answer in all of the posts I've read. From my design days I know that the plate's space is removed by welding the plate to the column wall or by some other means to block vapor and condensate from flowing between the plate and the column. Since I'm not a fabricator but want to learn more from you experts I keep flogging this nearly dead horse hoping to find an answer. Someday I may have something worth sharing but in the mean time I enjoy reading and learning about the great fabrication you bunch are up to.

Hey Rufus I am going to try to answer your question. With out soldering the plates to the walls of the column I am sure you have some vapor slip around the edges. But your are putting so much vapor up the column though It also must pass through the bubble caps.As for the restricted space around the edge, the vapor will take the easiest path with less restriction, which would be the bubble caps.
Look at it like this, if you have a garden hose and you put a Y on the end and one side say has a 1/8" tubing and the other has the 1/2" hose, you going to get much more flow out of the 1/2" side than you will on the 1/8".
Pretty much the same principle.
I hope that makes some sense to ya.

[Rufus]

KS, that does make sense. I guess what I'm hearing (reading) is that you minimize the problem by keeping a tight tolerance between the plate and column. Up until this point I've been assuming that the spacing between the plate and column was being sealed off by soldering or some sort of gasket. but I couldn't understand how you could braze or seal in such a tight space as a 4" column or smaller. Thanks for your explanations - all the whole bunch of you.

so i tried to give the ONE music store in my town a chance and keep the monies in town (even thought it was gonna cost me a little more).. he told me last week that he was going to place a order for the cork i needed, because he needed some too. i said cool,,, ill take a sheet. i called him today, and he said that he couldent order it because he couldent make the minimum order requirements. ONE HUNDRED DOLLARS .
boys, if a buisness cant make a hundred dollar order,, and im paying for almost half of that,,,, you know that times is hard.
i truly feel sorry for small towns,,,, and i dont know a better way to say that. it just seems like the future is grim.
any whooo on a lighter note,,, i guess im gonna order online and save myself a few bucks..... atleast i tried >shrugs shoulders<

Hey I'm in a small town! It makes sourcing interesting!!!

to me,,,, it makes the longevity of the town interesting.

[loneswinger]

Yep, then the music store owner goes home and wonders why he/she is not getting any business.

Times hard or not, they should have bought the damn cork anyway. He/She, more than likely just lost any chance that you would return as a repeat customer.

And the next flute adds its sweet voice to the growing song of the lonesome shiner. Shine on you crazy diamond!

[Kentucky shinner]

Hell ya that is what I wanted to hear.. I cant wait to hear your results..

[Mr.Spooky]

ok,,, im on hold now until i figure something out.... after puting my 1/16" cork in,, then the glass,, then the 1/16" teflon,,, i aint got no room to tighten down the threads..... what have i done wrong???
thanks '



spooky

[Mr.Spooky]

oh crap.... i think that i just screwed myself by not grinding this part down enough... now its attached and i cant get to it..
F**KKKKKKKKKK

[Samohon]

What about 1 thin layer of PTFE tape either side of the glass Spook...

May give you just enough room to catch the threads on the ferule...

Hope it works man...

[Kentucky shinner]

Spooky, Have you got a dremell drill? If you can scribe you a line on the inside for you to follow, use a cutting wheel. It will be a bit of a slow process but I am pretty sure it will work. You could then use a grinding wheel and make it nice and smooth when you finish. Let the dremell do the work, dont push it or you will just break the cutting wheels.
Damn man I hate this for you.. hey if worse comes to worse just heat the bitch up and remove the sight glass. Then you can work it down where you need it and just resolder it back into your column. That might be the best thing to do anyway..
You not fxxxked you can fix this..

[Samohon]

+1 KS... A dremel, slow but will get the job done....

Nice...

[Mr.Spooky]

here we go,,, i wraped the PTFE tape, and it sealed fine.
1 gal. vinager / 1 gal. h20
4:00 - full h20 and heat to both condensors
4:10 - bottom (#1 &#2) glass has condensation on them
4:15 - condensation on all glass
4:20- #4 plate bubbling
4:30 - PUMP DIED
5:15 - back from lowes w/ another pump
5:30 - deflag 88* #4- 105.3* #3 104.3* #2 110.5* #1 102.9*
5:30- #4 bubbling AGAIN
5:45 - deflag 89.8* #4 101.8* #3101.7* #297.8* #1 102.3*
5:50- only seeing bubbling on top plate,, turned h20 down on deflag. deflag 95.1* #4 98.2* #3 107.6* #2 99.8* #1 101.3*
6:00- deflag 99.1* #4 98.2* #3 107.6* #2 99.3* #1 105.1* deflag h20 output slow &hot, still no product from grahm
6:03 - product from grahm
6:05- - shut off deflag,, product coming fast now
6:15 deflag off 116.3* #4 99.1* #3 102.* #2 105* #1 102*
6:20- ran out of gas
this was only vinager & water,, so im sure when i run some alcohol through her, everything will change. i only have 3 small leaks to fix..
