I know what you mean about aggressive. What I'm using is very basic and the finish is very fine. I've used it to do gun parts before and was always able to replicate the US WW2 finish. If you look closely at the serial number picture in the previous post, you can basically see how fine it is. Also makes a great surface for primer to grip.
I have to make one correction. My compressor has a 20 gal tank and is showing its age. And I am definitely going down to the Rio Grande for sand. Work to shovel it but doesn't cost anything.
By the way when I lived in Tijeras up near Albuquerque, there was a sand blasting shop that had just opened down the street. I stopped in one day to ask what they would charge to blast a tub. They wanted $1500 plus the cost of the media. I didn't do it and now do it for 3 to 5 dollars a bag. Just takes time.
Here's a picture of the setup. Finished 3/4 of the bottom of the tub. I like the fact that the drain ports on the tank sump are brass. They look like you can fit a radiator cap on them. Ill try it tomorrow.
Looking great Mike !!
I can see that your tinning is still there, that is a plus !!
Hopefully I will get to this level soon, of blasting the tub.
I am using a blast media called "Clean Bite" that is made from crushed glass bottles, the bag says it has no free silica which is the dangerous stuff, found in sand.
It is about the same price as sand, and available at Northern Tool and other vendors.
I also wear a P100 respirator when blasting.
For the frame, and the tub when I get to it, I used a gas power washer with an attachment for sand blasting, and it works great but uses a lot of material
Also as you get an area done with the wet blasting, you want to stop, get it dry, then prime as you go to prevent flash rust.
The one area of our work that I really don't enjoy is blasting, but I like the results when done
Keep up your great works !
