It is very important to understand how the metal alloy makeup of different tubing affects the finished hoop size. Example: 1 3/8" by 17 gage fence tubing purchased from store "A" may produce a larger or smaller finished hoop width than the same size and gage tubing purchased at store "B". Not often, however sometimes the difference in hoop size is dramatic. Our hoop benders are designed to produce the desired hoop width "assuming that the tubing you purchased is within the average metal alloy hardness which is the case most of the time.
Because below or above average alloys are seen "Rarely" on the market, we strongly advise you to purchase only enough tubing to bend two test hoops before purchasing all the required tubing.
