Tesoro Eldorado on the bench

Nice and Sweet.
Can you please give us a link to those enclosures.
And also the shaft.Very interesting never saw such.
Thanks.

Huh...up from recently i also have a lot of problems to obtain that material. In the past i got enclosures and shafts from Bulgaria. Now that connection is lost. I dont know exactly who in Bulgaria is making those.
I would like to know and establish connection again, so to order some pieces from time to time. But...searching the internet i found only this link. Guy from this link is advertising Coinseeker Pro 2 which is some copy of Relic Hawk or Musketeer...somehow reduced and modified (it's been debated about this already, in RH thread).
So looking at those photos i spotted same enclosures and simillar shafts.
I would like to find out who is originally making those plastic enclosures so to conntact a man.
Here is the link:

If you find out the right man and address, pleas let us know here.
Regards!

I will try to contact an old friend there who might help.
And what about the shaft.I see that armrest can be adjusted.Never saw such before.
If I find something I will post it here.

[ivconic]

Yes, that photo i took from the link. I think it is very nice soluted.
In my case... i am using whatever come to my hands!
Sometimes i do make my own shafts, sometimes i use some originals...depends.
On this photos you may see - i used original shaft from MD3009a (Seben also).
Shaft is not big problem to make..but enclosure for detector and enlosure for coil is real pain...to make or to obtain. (really good enclosure..not some ordinary)

[Ultimate_Haze]

I see now.
This enclousures looks very handy.I am seaching now too.
Soon on later we will get a link to the manifacture.
I use ABS plastic enclousures for coil.But I have saw some fibreglass+epoxy.
Which one is better according to your excperiance?
This Eldorado is eching me more and more.I will go now buy the rest of the parts I need.

Both are good if you use later some hi quality and cold dry filling mass. I have expereinces with both materials, both are good.

Can you show the cable you use to conect the coil and the device?
This are MD enclousures that I can find.
Also you see the materials to make a shaft like on that picture you posted.
Tomorrow I will bend,paint and show my way!But you see similariyes I am shore.
If you are interested in MD enclousures they are like some seben and some MD....just let me now.
What is this mass that you fill with?Can you give a link?

Is it "Golden Mask" ? Looks like. Anyway...i like that enclosure. Of course i should draw quite another pcb for it, but it will not be a problem, easy for me.
About shaft... lower part is excellent and i like it. Upper part i dont like. I prefer uppper part to have "lazy S" bend like on my photos...
Or even better to have small, angled handhold like original Fisher 1265.
But it is never mind, it is just a detail in overall story.
If i could obtain ...let's say at least 5 pieces of those enclosures than i will draw another pcb to suit exact inner dimensions of that enclosure.
What should be the price?
Mass....hmmm i already tried to explain on TGS thread in the past. It is local product (but i guess in every country has it also by other name). It is the same mass as in HV transformers for tv's. 2 component, once you join them it is drying cold and has no relative movements. When dry after 10 hours it is solid as a steel! Not possiblle to break it at all....Once you fill coil enclosure with it - the end! End of a story... perfect!

[Ultimate_Haze]

I awso like "S"shape.I just wanned you to see the armrest that is exacly the same as on the picture you posted.I will go tommorow to bend the lower in "S"shape and then transfere the armrest again.And we have excelent MD shaft.You will see.
About enclousures if you like them I will send you 5 or what ever you want.Its worth to redraw good old pcbs.You will find that those enclousures are handy too.And you can solder pots directly on PCB.I dont now from which model they are.The cost is 4,5 Euro per piece.This is the price I buy them from shop.I still search for the manifacture.
Just send me pm with your detailed address.The shipping price will be my gift for you.
Also there are some DD27 aveilable 2,5 Euro.I think that I will be able to put two there.

Can you tell me syantific name for this mass.I use epoxy but its nasty work.

On this photos you may see - i used original shaft from MD3009a (Seben also).
Can you tell me is the lower part Al?This that is conected to coil?Because from this picture it look so.

I think you are referring to potting compound. Here's a link ->

Is this the same stuff?

"...Can you tell me is the lower part Al?This that is conected to coil?Because from this picture it look so..."

No. It is cheap plastic made in China! Ha,ha,ha! Poor Seben; bad detector and bad material also!


About mass:



It is so called "Smolit" and it is epoxy resin (2 components; mass and hardener). Just found a link:
http://www.fks.co.rs/fkse/maticna/pribor/text.htm

It is local manufacturer here in my country.
Mass is very tough to mix it. Once metal can opened; i divide mass in a portions for one coil each. Than i protect extra portions in separate cans and close those very good. Portion for one coil usually i mix very hard for 20 minutes to make it softer. Than join a bit of hardener and mix,mix,mix...sheeesh... tough in first few minutes, but than starts chemical reaction and mass is getting softer. It is getting a bit warm for a moment, not much...and last short. When mass is mixed good and soft, almost liquid than i add my secret ingredient!!!
After many experiments i found out that wasted laser printer powder is a hell of ingredient to join to prepared mass. Why? First i dont like natural color of the mass it is light gray...buiiiakk! Adding powder makes it black and nice. Also another trick; there is certain ammount of some iron particles in powder or something simillar so integrated in mass it is acting like some sort of very tiny "shield" against skin effects on coil surface. I noticed a much better stabillity in detector behavior when powder is joined in mass than without it. What a revelation! Hah!?
But you must be a carefull about powder dosage!! More than enough will degrade mass when dry and it will become porous. What is "enough" dosage for one coil? I can't tell exactly, i never measured, but it is very small ammount...let's say 0.3mL for one coil. So finaly, when dry, coil and bottom surface looks almost identical as any original coil....for example take a look at some Fisher 28cm spider coil, same look from bottom, looks also as same mass...shiny and black and hard as a steel! But Fisher 28cm Spider coil is (if i remember well) some 800gr weight, but my coils filled with this mass are usually from 580-650gr weight! I beat up the cat! (fisher) !!! Coil is 28cm (27cm). But newer 24cm coil is approx. 380gr. Same mass can be used also to fix and constrain any other coil. For example if you have housing for cc coil. You dont need to use much mass, just apply thin layer over windings and let it dry. You will be amazed after 10-12 hours. Also...if you want to protect whole pcb or just some important part from copying, scratch component values and apply thin layer of mass over those. Remember DBP2010? Remember the small piggy pcb? It was protected in simillar manner. Or lunatic ionic chamber in Mineoro? Ha,ha,ha! Same trick. Also in Future 2003 walkabout; whole pcb was covered with same or simillar material - not possible to scratch it without damaging some component... But in case of protection do NOT use laser powder in mixture!
Now i disclosed my top secret!!! Sheeeesh!!! Ha,ha,ha! Sooner or later i was about to post this here, anyway..so enjoy!
People! Do not discard your wasted laser powder! It is still very useablle! And a hell of a material for some works!
Cheers!

Hi ivconic What is the coils mh values for the el dorado .
