a better way to do it is start from the outsides ...drill holes 2" in....then measure 1/2 way between those holes...then 1/2 way between the middle hole and the outside holes...keep on dividing it up until you have enough holes.....8-10 inches between bolts is good......this way they will be divided up evenly
If i get some free time tonight at work, ill play with it and post it for everyone to see.
Time to man up and yank it John! Ray
