More Glass Bead Uses...
Glass beads are available in a wide variety of sizes and are primarily used in blasting cabinets for honing, polishing, peening, blending, finishing, removing light burrs, and cleaning most light foreign matter. Glass beads produce a much smoother and brighter finish than angular abrasives. Glass bead blasting produces a clean, bright, satin finish, without dimensional change of the parts or significant metal removal. For delicate thin-walled parts and thin welds, peening with glass bead material provides the right balance of stress relief without over-stressing and causing damage.  Glass beads can be recycled approximately 30 times making them an extremely economical choice in.  On metal surfaces being restored, glass bead "resets" the surface providing a new look.  The user can change the bead size and technique to achieve shinier or more matte finishes.
Selecting your grit
:
When choosing a glass bead size, think about the "anchor pattern" that you need for proper adhesion of the paint or finish material you will be using.  To illustrate the "anchor pattern", imagine the dimples on a golf ball, now imagine that you could change the size or depth of them, this is your anchor pattern or mil profile, it reflects not only how smooth your surface will be, but also that you will have the correct surface for proper adhesion of your specific paint or other finish material.  Each grit gives you a different mil profile or anchor pattern, however our MIL SPEC 8 medium grit (70-100) is our most commonly requested glass bead.
Shine - If it is shine you are after, then the following are true...
1.) Larger beads offer more shine - The larger the bead, the shinier the work piece gets. Alternatively, smaller beads offer a more matte finish.
2.) Lower pressures offer more shine - With glass bead, it is important to run at the lowest possible pressure that allows the material to still flow freely. This will increase the shine. Alternatively, the smaller (finer) beads offer a more matte finish.
3.) Less direct angles - To increase shine, try glancing blows that impact at an angle. Straight on, direct, ninety degree angles reduce shine and offer a more matte or satin finish.
Glass Bead is
NOT
Glass Abrasive
:
Glass Bead has unique characteristics that fit specific uses.
Do not confuse Glass Bead with Glass Abrasive
, they both have their places, but are used for completely different purposes. You will be disappointed if you expect the same results.
Glass Abrasive
is angular and cuts like a knife slicing away layers, it also breaks down quickly becoming less usable. Glass abrasive is used in situations where the users want to cut layers of paint, finish, or rust away with minimal risk of metal removal. It is also used when an economical abrasive is needed that the user will have a difficult time recapturing and reusing.  Glass Abrasive is also used on log homes and other wood surfaces.  Glass abrasive is typically spent after 1 to 3 impacts (glass bead should give you up to 30 impacts).
Glass bead
is a small round ball; therefore It is
not
the best choice for stripping and removing material like heavy rust and layers of paint.  To do this, you want an angular media, the most common being Aluminum Oxide, or others like Garnet, Glass Abrasive, Starblast, or Black Magic Coal Slag, etc.  Glass Bead is a surface profiling media.  It reduces stress to the surface being blasted, and imparts a smooth bright surface that can then be painted or finished to your requirements.  Many professionals use an abrasive to cut away the bad layers and then come back with a glass bead after to clean, smooth, and profile the surface to their desired specs for painting or finishing.

The difference between round and angular abrasives:
The term "bead blasting" has come to be the generic term for media blasting or "sand blasting". This may be confusing to beginners when they are choosing their grit, as they may assume that they should buy "glass bead".  In fact, different abrasives are used for different purposes. Glass bead is round, like a ball. It peens, refines, cleans, and shines metal surfaces as it is used. Additionally, it removes burrs and preps the work surface for paint or other coatings. While it will remove small amounts of rust, paint, or other material, that is not its intended purpose, nor is it an effective choice.  If you need to smooth out a surface, prep for paint, shine aluminum or other metals, or remove burrs...then it is a great choice.
When the user needs to strip paint, rust, or otherwise remove material from an object. They should choose an angular abrasive like aluminum oxide, garnet, or similar. These abrasives are shaped with sharp edges and will slice away layers to get to the good surface. Glass bead, being round, will repeatedly pound the surface.
Many commercial operations run two cabinets, the first with a stripping abrasive like aluminum oxide, and the second with glass bead.
As a starting point, every cabinet deserves to have two things sitting next to it from the beginning...Aluminum Oxide and Glass Bead.
Most users will be able to accomplish most of their tasks with those two products. A good starting point is white aluminum oxide 100 grit, and glass bead mil 8 (some call it 80).
How to choose an abrasive:
The first question to ask is whether you are working inside of a cabinet where the product can be contained and reused, or, are you out in the open where you are unable to continually reuse it?  If you are in a cabinet, then you should choose a higher quality abrasive like Aluminum Oxide, for your stripping needs. While it may be more costly up front, it quickly becomes cheaper as you continually use it.  If however, you are sand blasting in a garage where you are unable to recover a bulk of the product, then use something more economical.
In cases where you are outside of a cabinet, but are able to recapture the abrasive on a floor, tarp, or by other means, sweep it up and reuse it. But, before you put it back into your system run it through an old window screen to remove large debris.
The two most common problems with blast systems:
To small of a compressor.
When a system is not functioning correctly
, their are typically two main culprits. The first is an undersized compressor.  Typically people assume that if they are running the correct pressure, than it should work. However pressure is not the same as volume. Every individual system requires a certain volume of air, or CFM (Cubic Feet per Minute), to effectively pick up the abrasive and flow it out the other end.  Once you have the volume, than you can worry about the pressure your abrasive works best at. In addition, you must match your nozzle opening size to the amount of CFM your compressor can put out (you can find charts online).
In general, purchase the largest compressor you can afford, you wont regret it :-)
If your stuck...To make the best of an undersized system, you may consider the following: decrease your nozzle size, take breaks while blasting to let the compressor catch up, choose light abrasives that are easy to pick up.
Moisture in the system:
The second most common blasting problem is moisture in the system.  Every running compressor condenses the moisture that naturally occurs in the air and introduces it into your air tools, abrasive, or other operation.  It is a constant battle to combat this, especially in humid environments.  If you feel like the gun is "surging" in your hand, or clogging, you probably have moisture.  Additionally, if your compressor is undersized, and continually runs while you are blasting without stopping, it is constantly heating up, which in turn condenses moisture at an even higher rate.  Solutions to this problem include having a large enough system that it is not running all the time without a break, refrigerated air coolers or dryers (expensive), moisture removal filters (inexpensive), and various types of home made copper or metal snakes with drains, bolted to your wall (google it).
Most people are not going to purchase a refrigerated air dryer, but if you are handy, you can make a "snake" of copper with at least 50 linear feet (the more the better) of pipe and bolt it to your wall right next to your compressor. As the air runs out of the compressor, it will first travel through this snake and cool rapidly as it touches the metal.  A higher percentage of the moisture will then collect at the bottom of these pipes, rather then travelling on to your mainline and tool.  Additionally, there are many affordable moisture removal filters on the market.
