IDX-PRO+VDI

[CDI]

I just made wooden mold, my friend made housing using thermoforming method.
Sheet's are 2mm, this is enough for housing, very strong.
About the surface, i think u mean texture? Well, u can buy diferent textures sheet's, i like this.

About that disc, i have one proxxon. Must try.

Here this would be fine

I found some years ago with size 450 x 400 x 1mm, but it seems, that now this size is not available. 1 mm plates are very easy to cut with a simple scissors.
Here is a thread about vacuum forming.

CDI you have made the housing? Looks very cool, were can I get ABS sheets?

[blobber]

Very nice shape, looks perfect and professionel...cool.
I realy like the surface, what is the secret, to get such surface structure?
What is your plastic sheet thickness?




For cutting thin plastic sheets, I always use a cheap Dremel fake, with thin cutting disc saw like this here.

Blobber, how did you cut place for lcd? I tried with some sharp knife, tried with hot knife but the result is ugly hole, haha.

[CDI]

Ok, here is now. I hope.

Many many thanks CDI, I will try soon your advisings. I never thought about to buy more IC's, than I need. But of course, they also will have some tolerances, even in such industrial processes.
Btw, my stick is made from a foto mono pod, with a homemade fiber plastic tube, for the first segment.

Right CDI the link for your coil housing is not working, please do a new upload!
But anyway, vacuum forming is a very great way for diy projects, to get easy a perfect results.

Hello CDI very informative post,I will try those mods with my next build. Can't see your attachment it says invalid could you repost it please.

This is my housing for next IDX coil.
The same from my Deus 11" coil, abs plastic.

My IDX setup made in 2012, but the rod I use also for my TGSL and both Krot. With the concentric, I have only 30 cm in air for 1 Euro and with the DD 35 cm. But the concentric I like to hunt on the beach, I never dug deeper than 20 cm for coins and rings. Both coils are made with aluminum foil shield. Next I want to make a concentric coil with graphite shield. Maybe I can get more deep.
What else I can do get more? Any comment would be fine :-)
Maybe CDI know more?

I asked my archaeologist some months before, for permission to dig for relics. In my destrict area here in Germany, I need it to hunt legal, after two workshops in theory and practice some weeks ago, I will do the application to get it.

Hi Blobber, what u can do more? Delete 47R near U4 and set trimmer pot abot 10K, also 1M near U4 replace by 2M2. This will give u more sens. Next, try to match U4 with more gain, the same thing with U3.
About U3 (LF347) i bought 20 of them, and only 2 were realy good, deeper for 15 - 20%.
I deleted R7 and soldered trimer 200R for perfect amplitude.
If u decide to make your own coil, use 330N for TX stage, and 8 - 10 for RX.
Now freq. should be aprox 12 khz.
My coil's are shielded with graphite, i use Graphite 33 in spray, u can buy in Conrad, i found in Austria.
It is aprox 1k per inch.
That's almost all.
Great and realy deep machine in real soil, not only in the air.

Btw, realy nice looking, i like long stem. Look's like factory made.
Regards

Thats very nice man ! We hade the same idea even the foam grip is the same black with red! Is your stem made of 2 piece's can you separate them? Thats what I wanted to do but have no idea how to make it. I like the coil thats my favorite of the White's design. You helped me a lot thanks again!

Yes, it can be unpacked for 2 second's.
It performs very well, about 42 cm for 1 euro coin.
I had 2 tone board, but not working so good, it's giving iron tone on soil.
Yeah, coil is from XLT, but my second IDX work's better into mineralized brick's with double D coil.
I will post pic when finish.

Hi, I did only disc test and if iron is disced out at 3 of 10 it looses about 2cm. I had not made soil because since it's finished it rains, but I hope for about 20~25cm with a normal sized coin. Others have made soil depth test maybe they can tell you more. I had an original Blue Max 950 coil for testing and it performed the same as my DD27. Max air depth was 41cm with a Hungarian 200Ft. With LF347 you should get pretty good performance.

Thanks!
Yes I have made 2 gaps so the layer is not continuous. Well with a 50 eurocent ( I have no 1euro at home) it's almost 33cm. It performs a bit better than my TGSL in air test.

Hi, did you make some soil depth & disc test? I have Igsl and I am thinking about IDX as next project (after finishing magnum)... And air tests of IDX looks realy well, but I do not find any comparsion in soil so far.
