was looking around for my next engine and I like the sterling 60. what I don't like is that its in metric and I don't have taps or drills etc to easily work in metric. not that there is anything wrong with the metric system. I'm just not tooled up for it and I just really am not that good at converting drawings to imperial. like sizing up similar size threads and such. and last but not least I'm just lazy so I was wondering if someone has some already converted plans for sale or free?
