Sandblasters questionI

Yes, a blasting cabinet.

A dust collector is really nice too, it will keep the inside of the cabinet somewhat clear enough to see what you are doing.

Be sure to match compressor output to the blaster. Air must also be dry. Any moisture will cause the media to clump and not flow consistently.
 
I have heard of using dry ice blasting. I don't know how complicated that would be. You would need to get the dry ice every time you want to blast. DO NOT USE SILICA SAND!! Silicosis is a disease you do not want to get. Whatever you do, make sure you don't breathe the dust.
 
Ditto what Steve@Advance said. Unless you are doing carburetors or other more delicate items glass beads are way too slow. You need a blasting media other than sand even though they are called sandblasters. Match your CFM needs to your air compressor output. Nozzle tip size will partially your CFM needs. Try to keep your air compressor run time to less than 40% of sandblasting time. I try to roughly time the percentage that mine runs. Make sure your cabinet is large enough for your parts that I want cleaned. Double ditto the need for a regulator and a way to eliminate moisture.
 
Have seen video of that dry ice blasting. Crazy stuff. Something you might want to try is soda blasting, baking soda. the other thing that is also gentle is ground walnut shells. This is just removing paint and not rust. The NEWEST thing comming down the road is Lazers. Wow! Looks like Buck Rodgers.

I believe I would chemically strip the paint rather than use a sandblaster. On toys sometimes the metal is very thin and a sandblaster eat it up. Even if it did no real damage it would roughen the metal a lot to where you need a filler primer and a lot of sanding to repair the damage caused by the sandblaster.
 
I use a hand held sandblaster called a Speed Blaster all the time, works great and for small projects like that it would be handy. Wont take a big compressor to do toys. My friend does that too and said the chemical dip has ruined some pieces for him. My Snap On dealer had a neat looking small soda blaster on the truck this week, looked very neat and might be an idea also.
