_Jay_ I agree with Atlas - the bike you have is probably not the best choice.

That having been said, there are some things you can do to stand a better chance of success.

Wheels are very important. So are tires. Strong wheels will be needed to hold up to much loaded touring. You may want to post up your wheel details - at least the wheel size and spoke count. Since you mentioned the QR skewers - I assume these are conventional cone and race hubs. A tear down, degrease, inspection, and relube would be on my bucket list of "must do's" before any ride of much length. Make sure you have the correct tension set also when reassembling. Same goes for spokes.

As to the question at hand - you may be able to find clamps that work with your front fork arms to add an attachment point for a rack. However, if you can't find anything suitable it is conceivable to have some custom made. If you know of someone that works with metal, or have a local shop that does machining around, check with them. A saddle style mount with 2 bolts could be made to "clamp" on to the fork arms and if it has enough meat on the main block you can drill and tap it for the mounting screws for the rack.

As was already pointed out - if you cover the bases with strong wheels and get your accessories situation then add your trip gear to the bike and the weight goes up much your risk is going to be the frame/fork failing. A steel bike can be repaired easier on-the-go than aluminums/alloys, but I wouldn't want a frame/fork to crack on any bike at any time. Best bet is to inspect routinely and you may be able to catch cracks starting before they get worse.

You may look in to the feasibility of a trailer for your gear instead of packing it all on the bike itself. That idea has its' own set of challenges, also, though.
