Lowering Hydraulic forks

I am just researching now. Don't have a bike yet. All I've done so far is purchase a welder (Lincoln Pro Mig 180) so I can start to learn how to weld.
I wanted to know what the cheapest/easiest way to lower hydraulic forks? Yet keeping the same or close to the same suspension characteristics as stock.
I like the look of Cole Foster's blue bike build. There is a "Biker Build off" where he lowers his forks. He talks about cutting the fork sliders. But he doesn't show or explain exactly how he does it. Does anybody out there know his method?

I've found some other info. Some people modify them by using spacers, others by cutting fork springs, others by cutting and welding dampening rod.
I don't want to go out and buy a new set of lowered forks and I think it is more rewarding and more fun to make as many modifications myself as possible. Even if it means a steep learning curve.
So I would appreciate any information on this subject.
Thanks.
Gabriel

There is info/tutorials for many makes of bikes out there. I have never done this alteration, but I would feel comfortable doing my own considering the quality of the information available.

Yes I found a few good ones. This one seems to be the best at explaining not just step by step, but why those steps should be taken. Also, the pitfalls if modification is overdone.

This one found this illustration which I thought very helpful in visualizing the inner of a fork http://racetech.com/html_files/DampingRodForks.HTML
