Hi there, looking to do the rebuild on my DISA valves. Wonder what you used to cut the body open? Any tips for getting a nice clean split? Did you fuse the two cut halves with acid? Thanks.

I found the best and cleanest way is a sharp exact blade(just the blade) and a hammer.

Take your time going around the seam and hammering it in to split, going around parts at a time. You might have to score the seam with it to get it located right at the seam
