Title: Electroforming help
Post by: LesleyMac on January 20, 2009, 01:38:29 PM
Can anyone help?  I want to buy a rectifier/power supply to electroform and I am not sure what volts and what amps.
Can anyone advise me please, point me in the right direction or suggest what to buy.

Thanks so much Christine, I had just about given up getting an answer on this one, if would be great if you said where you got it but I expect I can find something suitable now I know the size.  Brilliant ;D

Hi Les, I haven't tried electroforming yet, but something like this is what you want (or, rather you will be well equipped with one of these):

http://cgi.ebay.com/MASTECH-VARIABLE-LINEAR-DC-POWER-SUPPLY-18V-3A-HY1803D_W0QQitemZ120369143739QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item120369143739&_trksid=p3286.c0.m14&_trkparms=72%3A1234|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50

If you take this to your nearest radio/elektronic store (maplin) I'm sure you'll find something.

Electroforming starts when there is just below 0.4V across the electroforming solution. I have been toying with making my own power supply by using a mobile telephone charger (of which we have many lying about the house). If I can find a current limiter, and some resistors, it shouldn't be any problem. But that is a project for the future.

Good luck, Lesley  :)

Thanks Julie, I was just trying to avoid buying one from the US, customs and all that.

I did have one set up by a guy at work with all the wires but he wanted his charger back unfortunatley, before I really got started, except that I could see it worked.  Diden't have the energy before to be honest but I am feeling better so I am full of enthusiasm again :)

I only mentioned the above because it does the job  :) Here's a uk based company which sells plating equipment, and they sell an "economy" rectifier, which I am fairly certain does the job on beads:

They have a more powerful rectifier as well (cost about 5 times as much  ::)).

Otherwise Maplin does a few, this one looks quite good:

Please let us know how you get on Lesley!  I've thought about having a try at this but it looked a bit scary  and technical  without tuition or instructions.....

For those who are interested, Wendy Inman has written a tutorial on how to build your own electroforming kit. It assumes you have a rectifier.

Hi Lesley,
I bought my rectifier, from maplins and this was also the cheapest place I found for the conductive paint, Balco is where i got the ret of my chemicals from.
Hope this helps
Dianne ;D ;D

Hi Julie and Di, both bits of information look very interesting..... in the etsy info she says that the cost of setting up is halved to $150!     would it really cost £150 to have a go :(   Think this might have to wait for another time for me......

Lisa, the rectifier is the most expensive bit of the kit - that's why I thought one day I'll have a go at building my own  :) For small items such as beads one needs only a tiny current and voltage, and so, if you know someone with an interest in electronics it shouldn't take them long to conjure up something.

Thanks for all this info, I am off to have a look.  Yes its quite expensive to get going, I paid a fortune for the conductive paint, think I went to the most expensive place.
You can either buy the tutorial or search on wet canvas, there is loads of into about actually doing electroforming.

Thanks again. :)

I think the Maplin one is the one to go for as it has a digital display although I think the cheaper one would probably do the job, just trying to find out if the crocodile clips are included.

Thank you all for your help :)

Thanks julie and lesley, will give this more thought and watch out for lesley's beads....which I know will be as gorgeous as usual :)

I have ordered the Maplin one that Julie suggested, thank you Julie, I think I just needed someone to point me in the right direction, there are so many to choose from.

I had a bead order so I paid for it with that :)

Now I have to go and make the bead order and also some beads I intend to electroform which takes a bit of thinking about first, got to get a plan. ;D
