Sandblast Cleaning of Copper

I was visiting Nortel last week and noticed that Peter cleans his soldered copper connections by sandblasting - cleans them up great - soooooooo

this weekend I pulled out my little table top blaster  from Romanoff - e-z Blaster
(you can get one here http://romanoff.com/store/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=894&category_id=40&option=com_virtuemart)  

I have a two hand blaster


I've had this little blaster for years and orginally use it to blast beads


You hook up to a basic compressor  and it has a light inside, recycles the blast material internally, has side hand glove access, the front panel opens to place your items in - all self contained  - easy set up

Here I take items before blasting

want to take off the wax so I can clean up and redo 

take off resist and clean up 

take off resist and clean up 

I love the light inside 

and the self contained and the small footprint of the unit 

works very well - I use a small pancake compressor

connect to the foot pedal

and after

Its a flat dull copper finish - so this does away with the chemicals to clean up the resist 

I think I"ll work with this some more 

Now that its out I'm going to play with it for etching beads and cleaning copper
