I built a carvin bolt kit guitar, but that was fully finished, and only needed to have the neck, tuners, bridge and prewired pickguard screwed on. I wouldnt even count that as a kit. I just like building stuff with my hands. I guess its in my blood.
The machine shop in the picture is my fathers aerospace shop. I used the bridgeport milling machine for all the milling and routing out the channels, sanding with a sanding drum, and even cutting out the body binding channel. I guess I did use a dremel to touch up some places here and there too...
I'll bet you had a ton of legos then
