alexandr, there seems to be no limit to your skills. Very nice.
There is however, a limit to MY skills... Frazer, if you read this, it was a big fail in the shop today. Usually I don't mind showing anything I make, but I don't even want to show this opener. I did learn what I need to do for next time I think, so it's not a failure, but a learning experience to be more positive. Just a design change is in order.
