Make shure your compressor can handle the amount of air and look for a good airdryer.

This is just the cabinet to contain the media, not the actual blaster. Also, what is an air dryer?

But yeah, I'm sure my compressor can handle any amount of air required by the size of blaster I'll be able to pick up, lol

This compressor was something else that followed me home - about 4 months ago - but I totally forgot to post about it.

Thanks for that advise Lee!

 

You'll be amazed how fast a small sand blaster draws a compressor that small down.

You'll need to open the drain cock on the tank and clear the water before using it with a sand blaster. A air drier is a device that removes water from compressed air lines. They usually have a clear body with a drain cock on the bottom, clear so you can see the water level and the cock to drain it. 

One of the guys has a pretty slick home made drier that cools the air as part of the process. 

When you compress a gas, the molecules are forced closer together but retain their original kinetic energy. But being closer together they bounce off each other sooner and move faster. Heat in a gas is caused by molecular motion, the faster the hotter. Which is why releasing the pressure from say a computer dust off can makes the can cold. The same amount of energy covers a larger volume. Also the more energetic molecules are the first ones to escape.

The pic below is off Amazon and about $60 + ship/handle, etc. Use your Google fu on "Compressed air driers" and you' get pages of hits from industrial units the size of moving vans to hobby sized inline driers like in the pic below.

33 gallons is "a compressor that small"? Here I was thinking it was plenty...

I'll do some more research on the air dryers. Thanks for pointing me in the right direction.

It's not "small" but 50gal is still considered a portable and 100gal a small shop compressor.

Don't let it worry you, you'll just have to let it catch up once in a while. It's not like you're sand blasting a car body or old boat.

Shaina indeed the thing frosty shows.

And draining before use

Air compressors should be drained of water on a regular basis regardless of what use your putting your compressed air to.  The water will accumulate and does cause the receiver (tank) to rust from the inside.  Eventually you have a leak due to it rusting through.  If you have ever cut open an old receiver you will see that the inside bottoms are typically well rusted.

With our shop air compressor with a vertical 150 gal tank, I keep the drain petcock cracked just a little all the time and it drains the water while it's running and after I shut it down continues to drain water then just exhausts the air slowly so the system doesn't have pressure all the time. On one line outlet there is a water separator and filter so the air coming out is dry and clean.  

I can’t control the wind. All I can do is adjust my sails. ~Semper Paratus~

Air drier can be as simple or complicated as you want to make it.  I have one with water trap, oil trap, and desiccant tank, followed by a CO filter.  The air coming out is clean, dry, and breathable.  Another one I have holds a roll of toilet paper as a filter. Then I have one that's simply a 2" PVC about 2 feet long with a drain valve in the bottom.  +1 on draining the compressor tank daily.  To make it easier to get to, you can remove the drain cock, and with an elbow, and short pipe, plumb it to out from under the bottom.  Easy to get to.

Or if you really want to get fancy. This is an auto drain, the duration and frequency of how long it opens can be adjusted. It's more intended for compressors that are online 24/7.

Two new additions to my collection arrived today from Germany.

Nice library additions, billyO!

In the "This will NEVER follow me home" department, I'd like to offer this FB Marketplace image of quite possibly the least appealing anvil & stand combo EVER.

Oh MY! You know the old saw about a little knowledge being dangerous? This one falls short all round except maybe it's bolted down.

It's Alexander Pope's "A Little Learning":

Quote

A little learning is a dangerous thing ;

Drink deep, or taste not the Pierian spring :

There shallow draughts intoxicate the brain,

And drinking largely sobers us again.

Fired at first sight with what the Muse imparts,

In fearless youth we tempt the heights of Arts ;

While from the bounded level of our mind

Short views we take, nor see the lengths behind,

But, more advanced, behold with strange surprise

New distant scenes of endless science rise !

So pleased at first the towering Alps we try,

Mount o’er the vales, and seem to tread the sky ;

The eternal snows appear already past,

And the first clouds and mountains seem the last ;

But those attained, we tremble to survey

The growing labours of the lengthened way ;

The increasing prospect tires our wandering eyes,

Hills peep o’er hills, and Alps on Alps arise !

 

That's a lot longer than I remember.  Thanks John, I knew someone here would know and had my money on you.

FYI, the "Pierian Spring" in Pope's poem is the spring of knowledge.  My late wife, Martha, had little patience with folk using isolated factoids and often used this quotation.

Pope is usually quite insightful, if not always infallible.

Thanks!  Now I only need 2014, 2015, 2017, 2020, & 2021 to complete my collection.

It's a good one. I like to kick the nearest rock and yell "I refute it thus!" Gets you some weird looks though.

Some Anvils are Rock shaped, before it rains and then they get Hammered!!

A great Johnsonian anecdote, to be sure, but not actually a refutation of Bishop Berkeley's theory of immateriality. Indeed, this famous kick gave a name to the logical fallacy that consists of dismissing an argument merely by calling it ridiculous rather than actually addressing its substance: "argumentum ad lapidem" or "appeal to the stone".

Uh HUH, as seen from people who's main argument is, "you  know you are" repeated rapidly. It's worse than when someone's argument devolves into semantic nit picking, forget the subject and pinpoint a word or pronunciation. 

From my point of view, "appeal to the stone," is the moto of those who have become a stone. . . Gall stone that is.

Sorry, I'm fighting with the latest update on my comp. which changes all my preferences, tabs, etc. to more market friendly ones. I don't know how they do it but some of my passwords are different on some sites. The "restore last" in the history is disabled but I have a list of ones I CAN "restore."

Sorry, frustration is getting to me. . . AGAIN!

Also, got a mail call a couple of days ago that I forgot to mention: an interesting little electric sparker that I will be mounting on my torch cart next to the gas saver. There's a video of it in THIS COMMENT in the discussion of that cart's build.

Mod note: the discussion of JHCC's log box project has been split into its own thread.

Like most of my jokes, it's as much self-mocking as making fun of the other guy. I know it's a logical fallacy, but you've got to take a little bit of enjoyment out of the counter-argument of "that's just plain stupid." I sometimes also use the similar E pur si muove, i.e. it's wrong because it's obviously wrong.

Nah, self deprecating humor is often the best kind. I love leaving people wondering if I was joking or serious.

I try to not be as obscure with jokes as I used to be. Having to explain Murphey's Law slowly got tiring.
