I bought a used media blaster box and was anxious to try it out. Already there is a huge difference on this part for the few minutes I spent on it. Even thou it's enclosed there's a lot of dust and I was out of masks so I will leave it for another day. Next I will clean up the part next to it, not sure what it is called but it will be welded onto the backside of this bracket. It was quite an adventure finding 2 that were usable.
