different ideas for ESL panels

Charlie, where can get naptha and what is it? I have tons of acetone, but will it deterioate the plasic container on a spray gun?

Ger, what in the heck is that? looks like someone tossed a grenade into an electronics store, computer power supply on the left, a scope behind the sub, siriesed resistors, and looks like a tube amp. Im gonna start calling you "electronic frankenstein" you can something from nothing and something, umm come alive. I rember the conversation, on this, but what do you plan on doing with it?

[geraldfryjr]

it's frankie and it' alive!

It is definatly ALIVE. check your mail on Monay or Tuesday of next week.
If you think thats alive, check out this, it is off post a little, but i can explain the relavance for this project.
The owner wanted to as bis as possable, those are 24" wheels on a Crown Victoria,Ford. No different the panels i want, as big as possable.
Mine a little shorter but wider for a better sweet spot, i am putting alot of love into this and sacrificing things along the way, as my friend did with his car, it may be big and oversized, but thats what made him happy, he does drive it on a daily basis, redone the rear end to accomadate the wheels.
In other words, no corners were cut to get something right, so there is the relevance, I work on those for a living, all of them for a living. Here is the picture, its worth a thousand words.

Charlie, I have a small hick up on the mock up for the stats, easy fix, what do you think? it was when we, you, well we decided to recut the sides. here is a pic of the hick up, now i just fiqured it out.
here are two hands trying to four. the cut-outs fit ferfect. but some more pics.

Naptha????
now i have a description;
Naphtha (pronounced /ˈnæfθə/ or /ˈnæpθə/) normally refers to a number of different flammable liquid mixtures of hydrocarbons, i.e. a distillation product from petroleum or coal tar boiling in a certain range and containing certain hydrocarbons, a broad term encompassing any volatile, flammable liquid hydrocarbon mixture.

In petroleum engineering, full range naptha is defined as the lightest or most volatile fraction of the hydrocarbons in petroleum, those boiling between 30°C and 200°C[1] It consists of a complex mixture of hydrocarbon molecules generally having between 5 and 12 carbon atoms. It typically constitutes 15-30% of crude oil, by weight. Light naptha is the fraction boiling between 30°C and 90°C and consists of molecules with 5-6 carbon atoms. Heavy naptha boils between 90°C and 200°C and consists of molecules with 6-12 carbons.

Naphtha is used primarily as feedstock for producing high octane gasoline (via the catalytic reforming process). It is also used in the petrochemical industry for producing olefins in steam crackers and in the chemical industry for solvent (cleaning) applications. Common products made with it include lighter fluid, fuel for camp stoves, and some cleaning solvents.

This almost sounds like fuel injector cleaner. But as said, I will use this and clean any residue off with acetone. Other products i have, denatured alohol, zylolal,
So where can i find naptha? Charlie, i have never in my life ever heard or read about anything similar or close to this stuff. You jnow i smoke( ciggarettes), i do not have plans on blowing myself up.
So thats where the weights come in, to steady the panels from spraying,
i have one air-line cooling conditioner for the compressor, two moister catchers, and what is called "an air cooler" for the final line running to my equipment at the shop. Auot drainage for the tank, pneumatic , every 30 secs whike running or every time it hits 120-125 psi, guess i need to post some pics instead of trying to explain.
But, where can i buy "naptha?"
very very curios, you should know me by now. I would like to have it yesterday or the week before.
I simply cannot solder my leads on the stats untill they are clean, very clean.
someone please throw me some information, i have given everything i can think of while i have the time to post( wife watching something stupid on tv) so this is it, I will check again, naptha??? and how to use it. Mavric

[geraldfryjr]

you can get naptha at the home depot or lowes in the paint department.commenly used as thinner in some paints. jer

[mavric]

Thanks Ger, guess i will be in the paint depatment.
BTW, what are your plans with your construction? It looks to me as a mean sub(vented or Tl) i know that the sub is old as mine as well, I think they were made a little better back in the day.
Much thanks on my reciever!!! I covered up everything with 3m hot glue before reassembling the cover plate, no need on pics of that, you could not see it now anyway.
Just make sure you check mail at home.
I have so much to learn and blessed with people with people with knowledge ,Mav

originaly I was planning a dipole sub sytem since i have like 8 or 10 of these drivers. but i'd like to try a transmission line also.this particular design i have right now is the best of both worlds,sealed and vented.it is vented with a small volume.giving a very tight clean sound while slighty augmenting the extreme lowend about 1.5db to 2db with a vent. jer

[mavric]

what about turbulance on the vent? i have come to realize that is why the enclosure i have is so huge, 1/4 wave length, no vent noise.
