I'm am in the midst of building / rebuilding someone else's GN-1 project whichis keeping me quite busy. I have been thinking, however, about venturing intoa material kit production sometime in the future.I work in CAD on a daily basis and have a client with a large wood and aluminumcutting CNC setup. (Will handle 4 x 8 sheets, and longer with multiple setups).The thought has occurred to me that pre-cut material kits may be of some interestto builders who do not already have a well equipped shop but want to build.I really haven't investigated liability issues or copyright issues andmy intent would not be to redraw any plans other than for assembly modificationsthat might be included.I am just thinking out loud (but not too loud) and would appreciate some feedback.As I said I have a current project that will keep me busy for some time,but I am thinking about something else to do when it is done.I have been practicing architecture for more years than I wish to admit and wouldlike to apply some of my skills to another endeavor. I love aviation and nostalgiatype aircraft. The Pietenpol certainly falls into that catagory.Jon Coxwell--------Jon Coxwell GN-1 BuilderRecycle and preserve the planetRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Jon,I've always thought there might be a small market for CNC rib jigs. For a good example, take a look at what Steen Aero Lab has. You could cut them for a large number of homebuilts, and maybe even some of the vintage aircraft, too. A lot of people complain about building ribs, and having multiple, identical, easy to use jigs might be desireable for some folks.Steen also sells a wing kit with pre-cut gussets.Wayne Bressler Jr.Taildraggers, Inc.taildraggersinc.comOn Jun 16, 2010, at 11:09 AM, "coxwelljon" wrote:> >>> I'm am in the midst of building / rebuilding someone else's GN-1 > project which is keeping me quite busy.

Thanks Tom,I like you have been making and re-making my metal parts by hand. I don't haveaccess to a metal cutting CNC but do have access to a wood, plastic, and aluminumcutting CNC. It is just a large flat bed plotter with an array of routerbits rather than pens. I was thinking that one could mark out the metal hardwareon sheets of 4130 ready for cutting by hand. That could probably save somematerial and time.The repetitive wood assemblies like ribs, routed or built up spars, fuselage gussets,and other wood members would be an advantage in time and material. I have only been repairing and modifying yet the task of ordering in enough quantityto reduce shipping costs can some times be daunting. Personally I like to build from scratch, but I have a friend who is building aRans from a kit. There are some real advantages.Jon Coxwell--------Jon Coxwell GN-1 BuilderRecycle and preserve the planetRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 16 Jun 2010 14:42:09 -0400
