The 1" tube w/.035" wall thickness does provide a tight fit. Tight is good. Tight is no play, no bending, more stability. It is not so tight that you cannot get them together or take them apart. Only time I had a little trouble taking apart was after a particularly rainy weekend and water had gotten into the joint. A little twisting back and forth as I pulled and they came right apart.
If your concerned, go visit a local tubing supplier and check it out first. A 2 sec. google search showed several in your area. Milford, Pipe and Supply, Midwest hose and Speciality, Steel Depot Hobbs, etc. Perhaps they could suggest an even better combo of materials than using EMT. EMT is a soft steel and not ideal, but it is cheap and readily available.
