Bead Blaster Lesson

I'm learning. I'm learning that if you start getting what appears to be a plugged feeder hose, you are. So now there's no more trying to "backflush" the hose by holding your glove over the tip and pulling the trigger, no more beating the gun on the grate. Now it's pull the hose off the gun and cabinet and run it through a screen to see what's plugging the hose. So far today it's been a broken lock washer and a piece of cloth/lint (wherever that came from). Been blasting and painting small '62 Lark convertible parts today. I hope everything I'm painting is supposed to be rattle can Rustoleum gloss black... if not, I'm doing rust prevention.

Also found another use for that screen style colander from the kitchen.

Couple three things (of parsimonious Stude nature) that I have learned about beadblast cabinets, and pressure pot sandblasters... A) Buy the cheapest sand you can buy....but double screen sift it when you put it in. B) Take a double layer of screen and put it in the bottom of the bead blaster so that also gets double screen sifted (the colander is not a bad idea, but it is still to big) C) Add a water separator immediately in front of the bead blast cabinet... D) Add an auto discharge water spitter to you compressor tank... (or fix yours with 1/4" copper tubing Lee... I melted mine too).. Jeff ('Backflushing a Harbor Freight hose will blow it up ..) Rice

On the "sweep" an Ensign was messing around with the sand-blaster, cleaning some doo-dad of his. The sand didn't seem to be flowing to the nozzle. He put his bare hand into the air stream to check. He found out that it was flowing!

On the same ship, if the EM2 had someone turn off the shore power, to check, he'd toss his large key ring into the box. Experienced, you might guess!

A) So I shouldn't be paying $30 for the 50 pound tub of 70 grit from HF?

B) I had the exact same thought... putting a layer of screen under the grate.

C) Funny how I've got one right after the compressor but I have water dripping where it enters the cabinet.

D) Done. Haven't had a problem since I put copper in.

E) The first thing I did was change my feeder hose with a stiffer hose from Lowe's because it was kinking.

$30... Yikes... I pay about $3.50 for a 50# bag of cheap sand.... It'd take me a year to hit the $30 mark .. (Just think about what beach in China their silica sand comes from, and you live in SC ) Put another separator right at the cabinet inlet. Dry dry dry.. Jeff

So I can run the washed sand through my cabinet? I guess since it works on vacuum I could run just about anything.

I use crushed Austrailian garnet, $12.00 per 40 lb. bag.

I found that cleaning and drying the air before the cabinet is worth the efford. Cool the air down as much as you can. I used 100 ft of copper tubing in a 55 gallon barrel with water.. I had a garden hose running cold water thru it. Then a water separator downstream of the 100Ft.copper tubing. I used an additional sand blast tank and stuffed it full of Kotex (new). I went to the Walgreens and bought ten boxes of Kotex. You will be amazed how much oil and water it absorbs. The ladies around me were amused until I told them that I had a harem. Have a blast.

I am damn sure glad you felt required to specify new kotex (ugh!)
