i put my shop in for 1 reason. i hate sanding off paint and fighting rust. i do my stuff and a few every now and then to buy new media or fuel ... or just beer money .
i dont really do much. fitzwell is the one running it and he can have all the suit time he wants. i can tell you this much , every small blaster is a pos . cheap ones suck. i've owned them all and threw every one of them away. all the major blst equipment co's sell from huge to tiny. they cost a little more but they will work every time with out fighting them. this is a good web site to learn on. it explains the medias and equipment needed to use it.
and the only thing at harbor freight worth carrying out the front door is the cash register.
