This may not be the answer or advice you are looking for... but if you are contemplating having someone fabricate a loader for you, by the time that's all said and done, and you add in the costs for the 4-way valve & hoses, I suspect it will probably come out the same (total cost wise) as if you bought a tractor with a loader already installed. My suggestion is since you just bought the tractor, sell it, and go find something that already has a loader and works just fine. Not saying you aren't capable of doing what you propose, just saying that it will be so much easier, and save you much time and effort, if you just sold the tractor you have and go buy one with a loader.
My first tractor was a two wheel drive JD750. Then I decided I wanted one with MFWD, so I traded it on a JD750 with MFWD. That was great for a few years... till I decided that I wanted one with a FEL on it. So, I sold that JD750 and went and up-sized at the same time and bought a JD790 with a FEL already installed. I haven't regretted any of the upgrades. That's the problem with these CUT's, they can make you want to empty out your wallet, once you get hooked on them. Almost like a drug addition lol.
