Here's something I did I'd be glad to pass along.
I bought my sandblasting unit at Tractor Supply. I also bought the sand and tips there. My blaster is the Siphon type
As you know they have about 5 different sizes of ceramic tips, and tips are EXPENSIVE if you do much blasting.
I figure I have already saved hundredS
of dollar with this idea.
I took the tip I planned on using most all the time (I think it was the largest one). I bought a 4 foot section of brake line tubing.
It fit just about exactly into that size hole of the tip. I cut off several small lengths of the tubing (just a tiny bit longer than the ceramic tip - maybe a big 1/8 inch)
Then I flaired the end of the brake line.
I put it into the ceramic tip; and with the end being flaired was held in place by the flair.
Then I use the blaster just like it was made. I watch the end of the tip and when the brake line material wears away, I stop, put in a new line, and go back to blasting. I am still using the original ceramic tip and I have used it over a year. It simply just wears away the brake line, and gets no wear to the tip itself. If you are doing this on a budget, you can't beat this.
ALSO... while I am thinking about it, I use "Black Diamond" sand blasting medium (also from Tractor Supply). It's about $8 per 50# bag.
DON'T just use this stuff once
, sweep it up and throw it away.
While it's true that new material has more 'teeth' and will blast better,.. you can use the same medium over and over.
I bought six bags when I started, and so far I have blasted my entire cab (inside), the truck bed (two times); inner fenders, tailgate, front of bed, and other assorted items.
I just make sure I blast on a heavy tarp (or something to keep it off the ground and "clean"). Then sweep it up and strain it as you put it back into the hopper. I use a screen from a regular home storm window. Lets the blast medium through, and filters out anything else.
Hope this helps
OH you folks were talking about compressors. I hook two compressors together and they don't fun full time. Between them they keep about 110+ pounds of air made while in use - plenty for me to blast with. They both make up to 150# before shutting off.
