One item crossed on my list:
Filled the drilled face with Plastic Padding Chemical metal. Grease removing, soda blasting, fill, file and ready. Considered filling it with auto body lead or some metal, but I'm trying this firs.
Also tried soda blasting to a larger piece that was not disassembled....cleans really nice, but does not remove rust. Need a bigger compressor. Funny thing is that this expensive soda blasting can works whole lot better that sand blasting can on soda....there must be a small difference on the structure? It is also whole lot economical...very much less soda is blown, but it cleans better!
