pat, taper the cholla to the blade till you like the look's and feel, if you have some stretch wrap wrap it tight but so you can still get the blade in, take some 2 part epoxy and fill it up, you can add some food color to the epoxy to get the color you want, then set it upright in a bucket of sand and set the blade, you can also wrap with saran wrap and tape it on if you don't have stretch wrap, then when it's all setup unwrap it and you will have to do some detail sanding to clean it up, comes out really nice, Bub
