Thought i'd stop by and have a look. I used to have a small business making cf parts. It made me chuckle a bit reading some of the problems some of you are having making patterns, molds and parts, I went through a very steep learning curve and had a very full waste bin years ago when trying to make stuff. At the time there was nothing like this or any info on the web, anyone who knew anything kept it to themselves but I did manage to make a good living out of it for a number of years.
