Hi Folks,
I have some success in fragging my relatively large Duncans, but i will admit 1-2 heads was destroyed in the process becos of the close proximity of the heads. i will share some pictures soon.
I also like to share that, i purchase a dremel 3000 tool from HOMEFIX to do the frag job.
a link to the homefix which i bought at a discounted price of $66. not sure now still have anot.
