Well after a few busy weeks leading up to hosting the boys from VNSC over the weekend I finally got around to getting some more etching done. This was the first time I got to use the new brass sheet I bought. I'm using a 1/2 hard sheet. I have a feeling the other brass sheets I was trying to use in other etching were not 1/2 hard, hence the funny results I was getting. I used the same process as before. The end result I was fairly happy with, close to been perfect. I had made a few changes to the design of the plates to make them better. I expanded the gap between the two spike heads so the rail could sit in better and I also made the plates a little bit narrower. In making them narrower I had to delete the small square hole in the design that's next to the spike head.
I'm still not 100% sold on a etching solution yet. The one I used was ok, but does take a while to etch and I believe because of that it rounds of the square edges more. I'm going to give Ammonium persulphate another go. They only draw back is that the solution has to be heated but it may be a small price to pay for a better etch. Sorry no pics this time our camera has gone missing in action.
