I am attatching a snap of my rather limited play space to give you guys some idea. Barrel end to target is 1 metre so there are limitations to the power of canon that can be safely used.
I agree on your comments on a gas gun Mike, but getting one is not really an option just to get this pic. My air rifle although very accurate is just too powerful to use in this space.
After my last post I tried with flat head pellets but they just mashed their way through so they are a non-runner. I have had 3 clear cuts but the trigger tripped before pellet/card contact, and where I got a clean cut and correct trip then the two strips of foil for the trigger stuck together causing the flash to strobe so that was a dead shot.
Lello, I am still using the Vivitar at min power giving 1/30,000 flash duration. Part of the problem is that I just went for this without sorting the trigger timing thing which perhaps I should have done as I would have had 3 good ones to post. Second and trickier thing is even at this range with the pistol clamped to my mill it is not consistantly accurate. I have done the 3 shot dry run all perfect, then set up the flash and that has worked fine but I had poor or partial cuts of the playing card. Very frustrating
. On the pellet shape front then pointed pellets would make perfect cuts but give even greater alignment probs to hit the card edge on.
Full marks to the guy that did those shots with a proper gun. I have not given up yet though.
Andy, you could be right about greater support for the card but I am not sure if the work involved in making that will pay off in terms of increased good card cuts.
