It all depends on your comfort level and mechanical abilities. You can cobble one together using an old water heater, steel tanks etc. but you really have to get the chemistry right. It isn't hard, sort of like cooking with dangerous chemicals, but it does take a certain amount of patience and the understanding that it is nigh on impossible to make ASTM quality fuel this way.
If your not into the building or chemistry, or flat out just don't have the time, spend the money and get a "Bio-Pro" made by the Springboard Company out of California. Yes it's costly but extremely well made and doesn't require more than a rudimentary knowledge of the process. Over the years it has proven itself to be safe and reliable. Good tech service as well.
Just pour in the waste oil and chemicals, close it up and push the start button. Come back 24 hours later and drain out the glycerin, push the wash button and 24 hours after that you have a batch of ASTM fuel (most of the time).
There are a bunch of people out ther flogging systems, but for the most part, you can duplicate their product for 1/8 of the money with off the shelf bits yourself. Don't waste your money, especially for a system that uses plastic tanks!!!! Not a question of if, its a question of when they will fail and in many cases they blow up or light up. Safety cannot be stressed more here. You are working with stuff that goes boom and the process creates the perfect environment for it to do just that.
Brew yourself a large pot of coffee, allocate at least four nights to research and log onto:

Really difficult forum to navigate but if you can weed through the BS, and the self important so-called gurus, there is alot of good info on the site about doing it yourself.
I built my own 8 years ago and processed maybe 20,000 liters through it over the years. None of it ASTM, but good enough for 100,000 miles on a used 6.2 with few issues. Made it mostly to heat my house. If I ever get back into it again, will definitely dig deep and get a Bio-Pro. Anything else isn't worth the time and resources needed.
Hope this helps.
