I always slide the footing on before installing the insert, check fit before gluing inserts than glue in insert slather a little epoxy on end of shaft slide footing down turn it on shaft to make sure it is coated and than let dry. It is best if you get the footing down over the insert but sometimes depending on different ones I have done, you have to do like above and put right at the edge of the insert. If you can slide it over the insert and even it helps even more as it stops the insert from being shoved into the shaft, works great either way. Shawn
