The table I am building has a 3-piece tabletop, with 2 pieces attached to a rack & pinion assembly and the 3rd piece butterflying up from underneath the table. On the top edge of the table frame, I want to put metal wear pieces with a UHMW tape on top. Is there any reason I should use 1/8" thick steel x 3/4" over 1/8" x 3/4" aluminum for the wear strip?
