New toy gloat!

I built a blasting cabinet 20 years ago and put a small squirrel cage blower on it. The blower was vented outdoors. It was just enough to create a negative pressure when in use. Abrasive fell to the bottom to re-use and the dust went out doors. No mess or dust in the shop. Best of all it cost me about $25 USD.

I've been using a similar system for years. The damned vacuum cleaner units that come with cabinets leave a lot to be desired------often leaking fine dust into the shop, and a less than comfortable noise level.

I agree. Wire wheels don't work. Abrasive blasting does! ;-)

Harold

I have a feeling your baddest arsed wire wheel is not as agressive as abrasive blasting.

I would advise against calling it a sand blasting cabinet.

Call it an abrasive or media cabinet and fill it with aluminum oxide media or something.

I could tell you what OSHA thought of our cabinet full of sand just in case you wonder why.

Think siliconosis.

I'v seen a wire brush cut a 1/2" plate!

I'll hook it into our central blower system and have a blast gate in line so I can choke it or it will suck it empty.

Bite me!

Geeez, looooeeeezzze--------who pissed on your cornflakes, Tom? :-)

Harold

Actually...pretty close.

Ive used Black Max to remove rust, and Ive used Tommy's knotted wire wheels, and at times...the wire wheels are the winners

HCl in a tank, with some water to make it higher volume and when steel is nice and gray - the rust floats off if brushed (with rubber gloves) and then slide whatever into a large tank of Baking soda with soda sitting on the bottom - to replace what is used up.

Steel comes out nice gray/steel color. Without baking soda the steel will rust.

This takes off Black Scale from hot rolled and rust.

Martin - been doing it all week.

I've seen abrasive jet systems in action....

What is HCI?

1. Please don't top-post, it makes quoting with coherent context difficult.
2. HCl. Chemical composition of hydrochloric acid. But - it's quite nasty and if your training doesn't include recognizing it by name, it'd probably be best to leave using it to people with years or decades of built-in safety experience with the stuff. It's _very_ nasty.

There's much worse. The home version of HCl is "muriatic" acid. The fumes are very irritating if inhaled, but otherwise not so bad. I use it all the time for derusting, get it on my hands, etc. I don't leave it on my hands, but it's not particularly painful.

Biggest precaution is against its fumes - they *will* rust everything. I only use it outside.

Bottom posting is for the mentally handicapped.I "What is HCI?" really does not need any quoting at all.

Just poking a little at those that insist that their way is the only way.

"A foolish consistency is the hobgoblin of little minds." Emerson

It does when I could have pointed out the OP said "HCl" by pointing to their own words.

I'm not insisting anything - I'm pointing out a convention which has been established over decades of usenet, and which works, and why.

See what I mean? WTF is _that_ doing all the way down here?

A word of caution. If you pickle heat treated objects, they should receive a roast afterwards to eliminate hydrogen embrittlement.
