    Horror Fright style blaster fixes.

    I recently made a reply to an old post about blaster dust collection MY DIY Dust Separator

    I have been asked to explain the function of the tall tower on top of the blast cabinet so I have prepared a PDF with details of all my modifications to the blaster. I know from experience that this forum only allows so many photos per post, hence the PDF, this post has lots of photos. BlasterMods.pdf

    Here are a few photos to get your interest. Click for full size images.

    I really like the tower/ drop side concept. Made sense as using same principle as a DIYer water trap built of several lengths of vertical tubing and elbow fittings.
    The issue of particles cling to hopper; most are powder coated, winding up kind of smooth but not very slick. Acts like static electricity, can't believe those materials retain a charge though.
    Wondering about those vibrating chambers, steel balls banging around propelled by compressed air, in a short sealed cylinder, attached to side of hopper?

    i do not think that there is any need for complicating things. Decades back I had a blaster with a deep hopper and hence steep sides. There was never any problem with that. With my present machine which has a combination of the stock shallow surfaces and my steep additions. It is only the original shallow sections that hold the media. The steep sides always stay clean. Anyway although not perfect I can easily live with what I have now, an occasional knock with a knee will dislodge any buildup. Other than having a sump with steep sides all around the simplest solution to avoid buildup might be to have some small compressed air bleeds aimed at the accumulation areas, a moving film of air.
