All I can say is "go for it!" Buy the kit and then you will have to learn! Everything I know is from this site, I feel obligated at this point to pay to be a team member and also it also lets you search for archived topics. I didnt start my builds yet because I am looking for receivers with the underfolder hole pre-cut. I have everything I need to build at this point besides the receivers. (Hydrolic press, vise, jigs, etc.) What part of Maryland are you in? I am 30 mins north of Baltimore. If you are close, youre more than welcomed to my place to use my equipment. If and when you take me up on this offer, hopefully I will have some 1st hand build knowledge. Read, read, read, then post. Good Luck!
also FYI just in case you do decide to but the kit:
The best places to get receivers is from http://dpharms.com (Underfolder receivers are back ordered.)
