  • Media Blasting Basics- 5 Tips to make your blaster work better

    Eastwood Dual Blaster Pressure Blaster

    Media Blasting is a pretty simple process when you break it down into the basics. You mix an abrasive media with high pressure air and shoot it out of a small orifice in a gun/nozzle. Media blasting is extremely effective if you make sure you follow some fairly simple tips. In this tech entry we will cover the basics you need to follow when blasting with a pressure blaster.

    1. Proper Equipment- The number one thing that will cause a media blaster to work incorrectly is a compressor that can't keep up with the blaster. Be sure to check the ratings of the blaster you are purchasing (or own) against your compressor. Ideally you do not want your compressor to be at max capacity when running the blaster. Constant running of the compressor without rest causes excessive heat which creates moisture in the lines and can cause clogs in the blaster (another reason to have a proper Air Management System). Remember that media blasting requires a high amount of constant pressure to work effectively and if your compressor can not produce the volume required, the blaster will NOT work correctly.
    -The industry standard for pressure at the nozzle is 80-100 PSI. Less than this and the media will not have the force needed to properly remove material. Running much higher than 100-120 PSI can exceed the blaster tank maximum pressure and cause the media to disintegrate when it hits the surface and reduce the cleaning abilities.

    2. Hose Length and Shape- While it's nice to have a long air hose that can reach anywhere in your shop or driveway, it can drastically hurt the performance of your media blaster. Try to keep your hose as short as possible and free of any bends or kinks. Excessive lengths and bends can cause the compressor to work harder and decrease performance. Keep the same tip in mind with your blaster hose. Every loop or hard bend in the line will cause a significant drop in pressure (we've seen 5-10 PSI for every hard bend or kink in the blaster hose).

    3. Water Is The Enemy- We hinted at it above, but we can't stress enough how important it is to have a proper air separator or dryer in line on your compressor. We suggest adding a new Inline Disposable Air Filter each time you start a new blasting project. They are cheap insurance to avoid those wet clumps of media blocking up your pressure blaster.

    4. Properly Adjust Blaster- Most pressure blasters have similar deadman-style valves that block air or media. These valves do not always need to be opened fully. Each media/nozzle combo and job require different settings. A general rule of thumb is that your air to media ratio should be 90/10. Too much media will kill the end media pressure when it leaves the nozzle. We suggest doing a test run and slowly open the media valve until just after it starts removing material off of the test piece.

    5. Technique- One negative thing that often gets said about media blasting is that it can warp thin panels and actually damage parts by removing too much material. This can usually be chalked up to improper technique. You want to have a steady side to side movement when blasting. DO NOT stop and blast in one concentrated area for any long period of time as it can warp thinner panels and remove too much material on some surfaces. Additionally, keep your nozzle at a 60-45 degree angle and aimed in the direction you are moving when blasting. This will help the media clean more efficiently and helps avoid sitting in one area for too long.

    Follow these tips and make your blasting jobs go as smooth as possible and do the job right. If you have any further questions about blasting feel free to send us a message or jump onto our forums and join our technical discussions!

  • Testing 1-2 1-2

    Repetition makes for the best final product. This is why our R&D department is always buzzing. From testing new products that are under development, to reviewing current products and seeing how we can make them even better. This at times can be a bit frustrating, but in the end we feel this what makes Eastwood products stand out from the rest of the industry. Here is a little insiders view on what we've been up to in R&D the past couple weeks.

    One exciting new product we are very close to releasing is a product that is best described as an "inner frame coating". Often times when restoring an old car or truck, you do extensive work to treat the exterior of you frame/chassis for rust. But, what about the inside of the frame? Many older vehicles actually rust from the "inside out". This product is specially formulated to coat, neutralize, stop and treat the rust or corrosion found in those places you couldn't reach with normal methods. This product is slated to be available in an easy-to-use aerosol can with a special "wand extension". This "wand" has a machined brass tip on the end that has been designed to give a broad "fan-like" spray pattern (check the pictures below for a sample of what the spray pattern looks like). This is the key to fully covering the inside of the frame. You can even see in the pics below how there is a fine "green" mist of the frame coating coming out of the bottom holes of the frame as Mark is applying the product. Throw away everything your tech ed teacher taught you when painting something; with this product you WANT the coating to be dripping out of the frame. Seeing that will tell you that you are getting a nice thick coating inside the frame.

    Keeping on the same wavelength of chassis and frame restoration, we have another product in the final testing stages. This product is being dubbed "After Blast" It is pretty easy to figure out when this product is to be used.. but to those that are unclear, it is a cleaning product sprayed on any part you have blasted. You simply spray  it on after blasting your metal clean and wipe down with a clean rag. I was amazed at how much contaminants it pulled out as Mark sprayed and wiped the chassis down numerous times! This is just another product that backs the belief that "prep is the most important step" when coating/spraying or restoring. Check out the pics below of Mark blasting the frame clean with our Eastwood exclusive Master Blaster Dual Blaster then testing the "After Blast" on the freshly blasted frame!

    As many would guess, one of our best selling product lines is Powder Coating. Because of that, we are constantly testing and perfecting our powder coating products. The past couple weeks it has been the powders themselves being tested. First was our High Temp Silver powder. We were testing a couple different samples for 1.) how they sprayed out 2.)How they cured and flowed out 3.) How well they handled the high temperatures that we guarantee them to.

    Also here are a few photos of some cool items being coated this past week at the Eastwood headquarters with some of our favorite powders! My personal favorite is J.R.'s vintage go-kart shot in our Starlight Blue Powder. Look at how all the "flake" shows up in the direct sunlight!

    Hope you all enjoy this recent "insiders look" at what we have going on here at Eastwood! Let us know if there are any products you would like to see as a DIY or blog entry.
