Thanks for all the comment guys, it looks like i should carry on, I've just been taking it one stage at a time but now i feel it would be a shame not to complete it. I can see now that the govenor has quite a force once it flys out and can imagine it shuting a valve. I had intended to paint most of it but i kinda like the shiny metal, The collum is ali and the rest is brass because thats what i usally work with and you don't have worry about rust. I would just like to show you one more thing that has helped me with this project, it's Stevensons square Collet block which makes it very easy when you have to drill a rod at 90 or 180 degrees, There's a Hex one to from Arceuro trade in the U.K. Here it is helping me with a govenor part.
