I'm looking for some ideas and solutions.
I have 120 steel cap head bolts that I'm trying to remove. At the top of each frame, just below the deck line, there are two bolts at each location.... 120 total... They are (or used to be) steel 5/16 or 3/8 diameter, 5-1/2" long cap head bolts. They go though 4 pieces of wood.
I've set up support blocks on both sides. to prevent tear out. Then tried drilling off the cap head. Once left with just a stud I tried pressing the bolt out. Then resorted to driving them out. At a bolt an hour this isn't working. They have swelled in the hole so hard, that I have bent industrial grade Die Ejector Pins in my attempts.
Right now I'm considering coring drilling the bolts. Now where am I going to find a 1/2" drill bit with a 3/8" hole in the center at least 8" long???? I plan to fashion a Stainless Steel Pipe as that drill bit. Unless there is a better idea.
That would leave a 5" long, 1/2" Diameter hole in hull and frames.... So how do I correct that?
Thanks in advance for the ideas!!!
