Anyone here do electro-polishing?

I stumbled across this site, and the technology looks very similar to anodizing/plating. Does anyone here use this? How difficult would it be to build an electropolishing kit, Caswell?

Edit: I just saw their estimated prices. 6 Gallon tank = ~$6000 US. OUCH! Maybe that's why I sand/buff all my parts.

I would like to get answers to this also. Like, what chems are invloved and does Caswell sell them? What is is the cathode material? ect. Caswell Manual does not cover this topic.

that would make life easy with that set up ....

Sorry guys. We've looked at this time and time again. It's the nitric acid and high current requirements that are the problem. Too much liability for us.

i wonder what all it will take to do a home brew set up ... but my insurance is sky high now i can see what it will be with some thing like that ...

There is a Yahoo group forum for electropolishing that may answer some questions. From what I see, it is very very expensive and you still have to buff the part to a near perfect shine. The electropolish just makes it a little better, and is used to make the surface pure on a micro level for sterile applications. I maybe wrong on this, but that is my take on it.

I've looked at this electropolishing thing many times over the past few years, with a view to making up a small kit, BUT - it ALWAYS comes down the same things.

1. The use of concentrated nitric acid and other unpleasant chemicals make it have serious liability concerns for us at Caswell Inc

2. The power requirements are similar to chrome plating, 1-2 amps PER SQ INCH of surface area.

3. Fume emissions from the tank need to be controlled properly.

4. If you are doing this on an amateur level, for the occasional small items, then the risks and costs are simply outweighed by standard buffing and polishing.

5. If you are doing this on a semi-professional level, with larger items, setup cost is horrifying, not to say anything about EPA concerns.

6. Whilst it would be great to be able to do this electropolishing, I personally think that using a vibratory tumbler and various tumbling media will give you excellent results, at a fraction of the cost, and more safely.

See http://www.caswellplating.com/buffs/...y_tumblers.htm

So, thats my 10 cents worth! However, we're always open to suggestions and don't have blinkered vision.

the epa is like a little cock roach problem ... i got them at or near my shop 2 the 3 times a week .... there were old tanks that leaked when it was a gas station and the creek next to it got most of the run off .... i just bought the place so i am no hurry to see if it was done right ,,,,, i had to set up my paint booth so it was to there liking and the filter set up is not like any i see before... i use hvlp guns i don't need any thing like it
