RE: The Sled
Sorry, I started doing a tutorial on another forum site, but they decided to sell it which caused liability issues so it was dropped.
If you are going to get serious on us:
here's one I found; [link]http://mmu.ic.polyu.edu.hk/Visual_c/mill_1/mill1.htm[/link]
another - see the lathe section also: [link]http://web.mit.edu/2.670/www/Tutorials/Machining/Description.html[/link]
Search the web for 'Lathe tutorial' or 'Metal Lathe tutorial', 'Milling machine tutorial' or specifically 'Vertical milling machine tutorial' - what you have is a vertical millling machine.
Get some books or try going to local community college also. See if you know anyone who might do this that is able to help you get started, or make some friends - you might be a handshake away from some help. Always tell them what you are doing up front - if there is no competition for them, they are more willing to help. It isn't hard, but it isn't easy either - you will have to do some learning and ruin some parts to get your feet wet.
Also, check youtube.com - there are a lot of good videos on there if you can find them.
