tabernacle repairs

I would like to hear from anyone with advice and/or tips concerning repairs to the tabenacle. A couple of really big waves from the wake of a large power boat gave me a good bashing yesterday and loosened it. It is still in good shape and in one piece but the screws seem to have given way (I unscrewed a couple and some have actually snapped off) and it has dropped about an inch or so. I am am also looking for any info concerning the cenerboard drum and how to get that assembly apart. I am located in Amityvlle on Long Island , NY so if anyone has a professional in this are that they would like to recommend please feel free to do so. Contact me through the forum or through email at lewis100@optonline.net Thanks for any help or advice you can give. Regards, Richard Lewis Chin Up FS367
