I was participating in another thread about rust removal when the subject of soda blasting came up.
So to keep from hijacking Sirgreggins thread I decided to start this one.
To answer Bill White’s questions
Yes I have a compressor it is a single stage 5hp with a total storage capacity of 160 gallons. The single stage compressor cycles on at 110 psi. and cuts off at 135 psi. The reason for the large storage capacity was I worked in a tractor trailer shop and used 1” drive air guns and many other large air use tools. I don’t work there anymore but I still have my equipment, including the compressor, a pressure pot blaster and a siphon blaster for use in a blasting cabinet. Neither got much use when I worked there. Most of the sandblasting we did was with a 125 cfm diesel powered compressor and slag from the steel mill. It rounded corners and sharp edges and left a surface similar to concrete. However the surface it left was an excelent surface for primer and paint on trailers and truck frames. Sand blasting also made a huge mess if not done outdoors away from the shop.
I now have the possibility of getting some woodworking machines that were stored indoors but humidity or condensation has left a rather heavy coating of surface rust.
I need a way to clean these machines to bring them back to useable condition. I would rather not use chemicals. Soda blasting seems to be a safer, more environmentally friendly way to go.
Some of what I need to know is,
Can I use the sand blasting equipment I already own or is dedicated soda blasting equipment required?
What is soda blasting media?
Where can I get it?
Pressures and orifices needed?
Results I can expect.
Is it very different from sandblasting?
