I Got the Big Box with a Zenith 750 CurZer in it

I got a very big Wooden Box with a 750 CurZer in it last week. Got it unpacked and got the parts all over my storage shed and my small shop. I'm ready to start and now I can't remember where I put all the various parts. Time to start construction, but first I have to find parts. The fun begins Jim Peale
