Thanks, I have the instructions from kt315 I think is was but didn’t really have the dimension, Thanks again and have a fantastic weekend what there is left of it.

I understand what your saying, and as for as carrying arms as you think is not true!!!!!!!!!! You have to get a permit to do so and it’s not easy getting a permit. And some states that’s not even possible. If you mean owning a gun that’s no problem as long as you have a firearms card BUT that does not mean you can carry it around in public and if you try it’s a free ticket to JAIL!
I’m sure you hear stories of how it is here in US, And I’m sure the stories I hear about Australia is probably not a fact either. The grass is always greener on the other side, RIGHT? We are getting ran by a millionaire that I think has no business being a president but that’s my opinion. I think,,,,,,,Well is guess I better stop now wrong place wrong time and wrong forum! Sorry all.

I will leave it there.

Yes its 193mm OD X 164mm ID, but for the width you have to think radius so its just on 14mm thick, but this is just the original former dimensions you can vary the measurements and the width and depth of slots to suit your purpose, there 37 slots inside and out , there is a thread here somewhere with all the info to make this coil, dont forget, to make it 3D, every 5 turns you have to move forward one slot, which starts the next winding on the other side of the former.

Ok thanks, so just to be clear 193mm OD X 164mm ID = 29mm jig width. ? How many slots inside and on the outside and what is the spacing between thee slots. Thanks again for the help. (I would still rather be living there than here). Who’s grass is greener?

I have Version 6
It is down the side in "Special Form"
Can do "Polygon, Spiral And Frame"

Thanks I will get my old pc out of mothballs and have a look at version 5

[6666]

The inside ring is 164mm, I sent the pdf to a mate in the USA and it printed correctly, that file is one I created myself by scanning a print of the former on my scanner and saving it as a pdf. The original print came from a Russian pdf
I printed my own pdf file on my printer and its a duplicate of the original Russian print. Anything I scan and print comes out at 100% correct size and shape, + or - the tolerance of the printer.
What happens when you scan something save as pdf and print it ?

I would be interested to hear from anybody else who prints out my pdf, and what they get.

I wish I was in Australia gotta be better than living here.

Australia in the 1960's was a great place, but now its very unsafe, thanks to our government's immigration policy, at least in the USA you can carry firearms to protect your self, and you have the death penalty, we dont have either . I wish I lived in your country at least I could defend myself.

Does version 5 work ?

[RobN]

From what I have experienced at my job pdf does not transfer from other countries very good. Trust me I deal with it weekly if not daily. Images will be out of wack and fine print unreadable. I guess it is the way or hardware they send them through and from where they come from makes a big difference too. I have got pdf from China and japan that come out great one day and are unreadable the next. Same from England. Don’t know who is to blame and don’t really care, just a fact of life I have to deal with.
6666, the picture you sent me (which I thank you very much for) printed out to be 178mm not 193mm. And I have the best programs available thanks to my job. I checkeded settings and everything is great. If OD is 193mm what is the ID please, and I can ignore it out from there, been trying to figure this out for days when I first print out the first diagram.
Thanks all. Get out and find a treasure. I wish I was in Australia gotta be better than living here.

Sprint Layout also makes it easy to make Spiral Coils.

Sprint Layout also makes it easy to make Spiral Coils.

Here is a double-sided spiral I did in Easy-PC between code compiles:

[ATTACH]43710[/ATTACH]

It has 60 mil traces with 25 mil spacing, N=24, d(nominal) = 10" (25cm). I chose trace width/spacing to keep the overall ring @ 1" wide. With 2 oz copper the trace width is equivalent to ~27 AWG so the "gauge" and spacing are almost the same as the OP's specs. It would be interesting to compare results.

PCBWay quotes $209 (plus shipping) for 10 boards, so right now it's a little pricey to find out. It's something I've been wanting to play with for some work projects so I may do it anyway. Obviously you don't want to waste all that middle real estate so maybe make it a set of progressively smaller coils.

A pdf should faithfully print the original no matter where in the world its printed, the outside ring should be round and close to 193 mm on A4 paper printed at 100%, if its not then your setup may need checking .

[RobN]

Wow I just checked and your 15 hours ahead of me. So have a fantastic evening mate. I’m going to bed.

[RobN]

6666 it seems like your irritated, sorry if ou are. Don’t mean to do that to you. Language can be a big issue. Hope you have a fantastic day, or night, whatever it is where you at. I’m in central (Illinois) United States. It’s 3am right now. Just have fun!!!

[RobN]

It looks like you have 20cm wrote on there ,correct? 20cm is almost 8 inches, but when I print it out it came out to be exactly 7 inch OD. Although it’s round and not oval it still didn’t print out to be 20 cm on my end. So it depends where you live on what you get when you try to print it out.
So I’m guessing 20 cm OD would make it 18 cm ID with a 20mm jig width? Sorry to be a pest but here in the states this forum comes out distorted. It’s a big world and what you send is not necessarily what everybody gets. Big difference from sending to United States to wherever. Just trying to make you all understand that. I have to deal with it ever day at work because there is very little stuff made in the United States and manufactures send me diagrams all the time that don’t match what I’m working on. It seems like when it crosses a ocean it gets screwed up. Please bare with us here in the states. Thanks again for the info you sent.
