Best anodizing guide?

That's the wacky bit - the powder, as you know, needs to be electrostaticaly charged - I guess there's a HT generator in the gun. I'm sure it'll be fine and 24VDC isn't hard to find.

ill be honest ive not read all 7 pages of posts.

when it comes to sourcing the required products where and what do people buy?

I know dies are easy enough to get off ebay, but acids etc...?

eBay - I bought my hydrochloric and sulfuric off eBay at 5l quantities - never been a problem.Similarly a degreaser (who's name I can't remember and it's too early to pop to the shed)

EDIT:

Things are getting more difficult...

Here the legislation and licensing requirements of Sulfuric acid, amongst others.

Looks like I need to go to the shed, after all, and dilute the little acid that I have left

Time to stock up on battery acid from your local corner car parts shop.

cant find any sulphuric on ebay?

[Doddy]

It's becoming difficult to find - presumably because by July it will be illegal (punishable by prison/fines) to sell sulfuric acid above 15% conc. to any non-EPP license holder (and by November, illegal to own it without a license). Battery Acid is normally around the 30% conc. - around the strength touted as required for anodising. Hydrochloric acid is illegal above 10% conc. which buggers up anyone looking for alternatives to ferric chloride for PCB etching at home. Today, I can find hydrochloric acid advertised for sale on eBay at 35% conc. - I bet if you tried to buy it it would quickly be removed from sale.

The EPP license is within reach of the public, but at a cost of 40 quid every 3 years - for each and every substance identified on the license, it makes casual dabbling with plating and/or anodising something that needs careful planning. It makes supplying the chemicals a complete pain in the arse.

Acetone looks to be under the glare of government - expect that to become illegal next.

I blame Europe. And the idiots running around harming people.

EDIT: My bad - Hydrochloric acid is not a regulated chemical, but is a notifiable one - so any suspicious activity surrounding the sale is reportable to the police. As are a whole bunch of traditional fertilisers (okay, so my interests - electronics, some limited form of CNC toys, and Sunday down the allotments - all going to get me into trouble!)

Yea the new laws coming in sound pretty dumb. This is not really a problem outside the getto of London...


I canceld the order with the eBay seller of that electric powder gun.
I sent multiple messages and they did not respond to any of them. They also didn't ship the after a week.

They have reduced the price to £18 https://www.ebay.co.uk/itm/253570991736
I know this device is cheap but they are only going to get ~£10 after fees....

They are selling quite a few every day and one other person has not had any messages back from them or the item shipped..


Stay away...


Bought this one instead.

No wires. Uses the plastic nozzle to generate the positive charge and uses your body as the grounding.
Should be arriving tomorrow (Monday).

Will review..

Try motor trade outlets I can get acid in 25l drums from a parts supplier, ebay you can buy 25l easy enough as well.
