Thanks for the replies, good to be back and feeling welcome. I'll keep an eye out for D_Hall, think it rings a bell. To tell the truth Im finding it hard to remember many names from then. The closest contact I had with anyone was a couple of the Aussie fellas and an older American guy signed "Chewy" who passed on around the end of the Spudtech forum.
Currently I'm still deciding what to look at building, I know it'll be combustion cannon, probably metal construction as larger dia class 12 or 18 PVC fittings cost a bit here. Going for a metered fuel setup, chamber fan, breech loaded (ie coaxial), pretty much a normal intermediate design cannon at the time I left (apart from the steel construction). Wouldn't mind checking out other ignition systems too. Just thinking aloud at present, catch you around the forums later
