    Default Modifying a boat top ???

    I am modifying a T Top for a pioneer fishing boat. It appears to be 1 3/4" OD aluminum tubing. I am just shortening the 2 uprights on one side(the top is laying down in the pics). I am taking a 3" section out and butt welding back together. Will inserting a smaller diameter tube and using it as a backer be sufficient enough? I will sand the weld flat and polish after words. Would drilling a 3/8" or 1/2" hole below and above the but joint to use as a plug weld to the inserted smaller tube make it any stronger or will the pull pen butt weld be enough? It uses the 4 circle plates and the two angles above it to mount to the sides of the console. Thx. Dave
