I have been involved in building several wooden towers for six foot Aermotor mills. Regardless of size, the process should be the same. Also, constructed a wooden tower for a B702 using upright treated pine timbers 6"x6"x 24' with a 5 ft stub tower.
After having visited with many windmillers and viewing wooden towers over the years, it really became obvious that you don't really need "construction plans". Build to suit you taste . Start by selecting the size of timber you plan to use. 4"x 4" treated pine from Home Depot or other lumber suppliers, using the length you desire, works well for 6 and 8 foot mills. 4x4x2 and 4x4x4 treated pine for cross-bracing and girts placed and bolted with galvanized carriage bolts, nuts and washers, again to suit you eye. Start by laying out 2 upright timbers on flat surface such as car port, garage or driveway. The angle of the stub tower will determine the spread at the top and bottom of the wooden tower, generally speaking, although some other dimensions can be achieved with appropriate cuts in the timber tops. My six foot Aermotor towers are 5.5 ft. square at the bottom but you can achieve a "Nebraska wide spread" using other construction techniques. See the big book on American windmills or other publications.
After laying out one side of tower and bolted together, flip it over and duplicate the other side following the dimensions used on the first side. Then you spread the tops and bottoms of the two sides to create duplicates for the other two sides, again keeping the stub tower in position to bolt the four legs to the stub. A good power miter saw, such as DeWalts, will do great to duplicate the angle cuts for the girts and cross-braces and of course, a good re-chargeable drill for the galvanized bolts.
There are issues to worked out but this should get you started.
Good luck,
