It may not be the most proffitable of crafting, but if you wish to go components, go for it. It's all about having fun. As for what to do....Get some mining equipment and work on getting as much ore and energy matter as you can, these are the materials for your crafting. You will also need to look for the blueprints of what you want to craft, and the blueprint book they go in. You could find a miner to trade for the materials, but is sometimes easier to try for your own. Now as to the crafting..... Once you get the blueprint in book, you can view what is needed to craft the item. (double click book to open it, find your bp, right click it, go to stats, it list materials needed) Then collect the materials needed. Now it is time to find a crafting machine, they are in some of the major cities. (Port Atlantis has a few inside the deluxe trade center) Find the machine for what you are crafting, they have ones for each type of item, and I have found I get better results if I use the one for what I am making. Click on the machine (right click to access), it will open the manufacturing menu, and your inventory. Open the bp book like before and find the bp, left click to add it to the craft list. Then it will again list what materials it needs. Put in what materials it names, multiples can be used for multiple attempts. Then you can chose "quantity" or "condition", for components I recomend quantity. Once you have added all this and selected the options, click on the manufacture button and it will try to make the item. It useually takes several tries to get it to work, so expect at least a few failers, but this is how your skills will go up. That is the basics of crafting, and the same goes for all items crafted. Basicly... Get blueprint and book, find materials, goto machine, insert stuff and options, then crafts.
Good luck and I hope this helps. If you have any more questions give me a pm and I will help with what I can.
