[R-390] Removing MFP

[Chris Kepus]

Hi Doug,

When you say "fine bead", are you referring to glass bead or ?   I have a
TIP cabinet and have started using it more and more for electronic stuff
than the car stuff for which it was acquired.  I use glass bead for more
"delicate" items and when the going gets rough, I switch to aluminum oxide.


Are your chassis stripped when you do the blasting or do you mask off
portions?  I've looked at putting together a soda blaster for my electronics
blasting because you can literally blast anything without causing damage.
Only issue is that it doesn't remove rust which, of course, doesn't occur on
most metals used in our radios.  For rusting ferrous stuff, either glass
bead does or al oxide is the ticket.

Look forward to any response you may wish to send.

73,

I have found Brasso works very well with a little elbow grease or polishing
wheel as well, especially on the IF/RF cans etc.  Now as for the the side
panels and chassis, I bead blast those with a fine bead.  It works great,
and makes quick work of it.  I get all of the crud of of it including the
rims of the holes.  I say this because I have had many cuts on my hands from
trying to polish the holes in the side panels!!!  It hurts.  
 
After it comes out of the beadblaster, I just wash them off with soap and
water to get residue off it, and Im ready to go.  I also use it for the
front panels as well.  Does a great job and no chemicals to worry about!!
