Quote for machine scraping hobby mill.

A proper scraping job on a knee mill is an extremely labor intensive job, and takes meticulous planning, and excellent metrology equipment.. If you don't have proper datum points established, you can spend many hours of your time making your mill much, much worse than it originally was. You can scrape in your X axis perfectly to itself, and have it out of square with Z axis, same with the Y. I cringe when I read about a new machine owner deciding he needs to scrape his older mill or lathe, and has taken NO classes on the subject.
 
@addman16 are you confusing tramming with the need for scraping? If you actually need better precision and tramming isn't enough then you quite frankly you bought the wrong machine. Perhaps a rebuilt FP1 or a tormach would better suit? You will of course need to add another 0 to the cost.
I have a King KC20-VS2 which is essentially the same machine as yours and even without tramming was more than accurate enough.

Jetlag,
You are correct a well taught single class only brings awareness to the attentive and motivated learner. And you've clearly stated how much physical work it is, and then there is also the how to use datum, as well as a clear and appropriate plan, etc. or disastrous results will happen.

However, outside of this and more, the entire process really isn't that difficult, and because each scrape is only take off small shavings of metal it's difficult to break a machine that is already broken. Rebuilding is fun and relaxing. However, I'm not trying to do it 40+ hours a week, I don't have kids to feed and the mortgage is paid off. Hobby rebuilders can take their time, be careful, go fishing, and enjoy the rebuild.

That is a tall order- you have to figure the amount of hours it would take and to pay someone even a minimum say 25$/hour
at maybe 40 hours would put you at a grand- IF you could find someone. Likely it would take longer or cost more or both.

How badly off is it? Lots of people have converted these- why not just do the conversion and come back later and do some
scraping on it? You'll be taking it apart many times anyhow during the process

I'll bet after you convert it you could find a buyer for it that might just need it for a specific CNC use even if it's not a Haas

If you could drive it to Minnesota we could make it a class project and teach you how to rebuild it.
