I successfully completed my repair, today. It really wasn't too difficult. Managing and removing pulverized glass was the most tedious part. Both Jake's and DC LifeTech's suggestions were helpful... lot's of heat, glass safety measures and a strong device for cleaning glass from the edges... I used a very good sharp pen knife (I'm an olde-timer!)
Due to extensive glass pulverization... the center of the broken glass was removed 'close' to the edges. Then, I slowly removed the remaining glass from the edges with lot's of heat.
The kit I purchased (iPad Air Front Glass/Digitizer Touch Panel Full Assembly ) had a new home bottom. So, I didn't need to be careful to conserve the old one.
I did the repair while pleasantly listening on radio to Martin Brodeur’s no. 30 being retired... raised to rafters at "The Rock" (Prudential Center) .... the whole ceremony... and, part of the subsequent match with the Edmonton Oilers....
