I'm building a sand blasting and cadnet and was looking around the net and found this great site as i love hot rods and tools .so i had to do a post of my own about this subject. here is how it all started i was in a store called kitts tools . a local compeny here in michigan, and was looking at the sand blasting machines thay had on display and was thinking how simple thay are to make . so me being a scrapper by day and a builder at night i went to home depot and bought some plumbing parts air fittings and started to build my blaster out of a 30 pound propane tank . now this tank has two 3/4 taped holes in the top so one is for filling the media of your chose . the second hole i plumbed with pipping from 3/4 down to 1/4 for the air fittings to work. used some air hose to run from the top of the tank to the bottom of the tank . i had to install a fitting in the botton of the tank .so you will need a drill and a welder to install the gate valve for flow control .after the gate valve i installed a tee with air fitting on both sides so i could connect the air hose from the top of the tank to the bottom . at the end of the hose im using a ball valve for my on and off with the nozzle on the other side . i have done all this for less then 25 bucks . so i see it as a 125 saving from the cost of buying one from kitts or ebay . so i hope this helps someone out thats hard for cash . and from looking around i seen a good idea of using a sander as a shaker so this what i will be using for my econo blaster.
now im new here so i not shure how to post pic's so if any of you would like to see my econo blaster feel free to contact me and i will send you pic's
