Brief Description: Futzing around with Front Door Threshold tubes
Well, one of the advantages of being a slow builder is studying everyone else pioneer techniques and kinda making a gumbo of the best stuff. These front door threshold tubes are pretty tricky. Russ "the Erbman" coin the phrase "futzing around with em" till you get it right. Others have used the same phrase at this step. They have a bend, a bulge and must be pretty spot on dimension wise. Can make your head hurt. I laid out center lines at the 15" mark on the table and then marked for the bulge at 36 1/2" (STA C/S) The hard part is getting a starting point and then getting some good marks to start cutting and coping. I took Wayne Massey's suggestion and cut a T-11 tube 42" and then cut out a 16 degree pie at the 16". That worked real well. I had a brace (alum angle) up for the 7 1/2" mark. I then had a plumb vertical that I spaced out 3/4" for the width of the tubing(see the white block). The edge of that vertical was on the 15" mark. All I had to do was set the tube up, level the 15" run and get the other end at the right height. Made my marks and a few trips to the grinder for each end and she fell right end. Tacked the ends and then the splice. Repeated for the right side.
