if you work several hours a day or every other you can have it close in about a month. working on it 4 hours a day I would say about a week maybe 10 days. I am retired and can build a 4* 60 in about a week maybe less, I have been building airplanes boats cars for over 30 years or so.dont let problems that arise worry you most of them can be fixed really easy. wood is very easy to work with. just make sure that when you start your build you have a good flat surface to build on and things you aren’t sure of or have questions about ,just post them here these fellas quibble at times but they all are a good bunch.
