The bead blaster cabinet that I have was produced by North Coast Prototype Models in Perrysburg, OH. I think they may no longer be in the business, but an internet search for "bead blasting equipment" turned up some others that look quite similar. It is essentially a glove box with a cover that can be opened and sealed closed. There are two mini-fluorescent bulbs inside. It has a "pencil" that sprays the beads once a valve inside the box is opened (the valve controls the air supply). The beads Just fall to the reservoir at the bottom of the cabinet and the pencil intake hose is at the bottom of the cabinet. Periodically one has to replace the beads as they eventually get damaged, but I think I've only done that once in the many years I've owned it.
 
I bought 50 pounds of 220 Lionite Brown Aluminum Oxide beads when I bought the blaster, but still haven't used them all.
 
Hope that helps.

Ken,
 
This is a topic worth discussion on the list.  Can you tell us the brand name of the blaster and what type of grit you are using?

I have found two methods that work to varying degrees of success, depending upon the paint that has been used. I have used 91% isopropyl alcohol (available in pharmacies) which seems to work well with some paints (I've had good luck stripping Roundhouse factory paint with it). However, there are some paints it simply doesn't seem to touch. An example I've found here are some Walthers tank cars. I would suggest trying that first, because if it works it's pretty easy.
 
What I've found most successful is using a bead blaster. I would have been afraid it would damage the plastic but it doesn't do that in my experience (though I tried it on a junk Athearn box car body I had around first just to be sure). This is something I read about on the internet and it seems to work well. I have to turn the air pressure on my compressor up to 100 psi (as high as my compressor will go). It's almost like it just "erases" the paint. The internet site (sorry I don't remember the location any more) said that you could even paint the models and then strip them again if you weren't happy with the paint job. I'm not sure bead blasters are all that common. I bought mine so that I could use it to etch brass slightly to get paint to adhere better (that only requires 60 psi). If you would like more information or have questions, please contact me off line.
 
Beest regards,

What is the best way to strip the factory paint on a locomotive along with the unwanted decal so you can paint it in Q colors?
