Default seperating the liner & hull

Hello everyone Great web site I see that this will be a valuable tool to help me with my restoration. I plan on posting all the pics of the process. Recently I had bought a 74 20cc O/B and I can see shes gonna need alot of work. A new transom hatches, console, conpartment liners, floors ect. Heres my question, Im looking at this project and every thing I want to do to this boat and Im wondering how hard would it be to seperate the liner from the hull. would it be easier? Has any one taken this aproach? I was looking around at the bedding compound and in alot of places it looks like it has broken loose. If any one has any insight into this process I would love to here what Im in for.
Thanks

I AM NOT SURE ABOUT THE 20 I HAVE A 23 BUT I TOOK THE CAP OFF MY 23 TO RE DO IT, AT THAT TIME I LOOKED AT HOW THE INNER LINER AND THE HULL WERE CONNECTED. MAYBE THIS WILL HELP A LITTLE. THEY FUSED THE INNER LINER WITH THE HULL AT THE TOP WITH POLYESTER RESIN. THEN THEY SCREWED THE CAP, INNER LINER AND HULL TOGETHER. THEN THEY ADDED THE RUB RAIL WITH EVEN MORE SCREWS. AS FOR THE INNER LINER TO THE STRINGERS THEY USE A POLYESTER RESIN BEDDING COMPOUND TO HOLD THEM OR LET SAY LET THE INNER LINER REST ON TOP OF THE BEDDING MATERIAL, ON MY BOAT THAT STUFF CRACKED IN SEVERAL LOCATIONS SO I CLEANED IT UP AND TRAWLED IN EPOXY RESIN AND FILLER TO RE SUPPORT THE WHOLE THING I EVEN USED A SURING AND INJECTED EPOXY STRAIGHT DOWN INTO THE CRACKED AREA’S TO HELP RE SUPPORT IT AGAIN. IF YOU ARE GOING TO SEPARATE THE HULL FROM THE INNER LINER (IF IT IS LIKE MY 23”) YOU WOULD HAVE TO USE A JIG SAW AND CUT BETWEEN THE TOW THEN USE A BLOCK AND TACKLE TO LIFE IT UP AND AWAY. PERSONALLY I THINK THAT WOULD BE THE BEST WAY TO GET TO THE ENTIRE HULL FOR INSPECTION AND REPAIR BUT I DIDN’T HAVE THE EQUIPMENT AND WAREHOUSE TO DO THAT. SO I WORKED AROUND MY JOB BY REMOVING THE CENTER CONSOL, GAS TANK DECK PLATE, GAS TANK, THE DECK UNDER THE GAS TANK, REMOVED THE CAP, AND REMOVED THE BACK PORTION OF THE INNER LINER TO DO THE TRANSOM. IF YOU DO IT THE WAY YOU ARE THINKING YOU WOULD BE ABLE TO FLIP THE INNER LINER OVER AND REPAIR ANY SOFT DECK FROM THE INSIDE WHICH WOULD LEAVE THE DECK COSMETIC APPEARANCE IN TACK. I SUGGEST ONE 6 PACK OF BUD’S AND ABOUT 2 HRS OF THINKING FIRST BEFORE YOU MAKE YOUR DECISION.

Mines is lifted up around 4" currently, just high enoungh to get new bonding in there. I assume the owner before me had it up as well but I can't seem to find any of the bedding compound anywhere? Not even a hint! I can't see Potter leaving it out but......
On mine the deck and stringers sit very close, anywhere from 0-1/4 inch. I know on some other SC's it's much more. Anyway, Bimini if you want pic's of the deck up let me know and I'll send them over.

Can’t really say if it’s a good or bad idea. If you plan on removing the core of the liner when its out, I would think you will need a pretty good means of supporting the liner while its out and upside down. I’m sure you have re-cored a hatch and can see there isn’t much there once the wood is removed. Depending on the space from the liner to the stringers, it could be expensive just to replace the bedding. I had to take part of the transom with my liner when I replaced the transom. The spots above the rear hatches on the transom were tough as nails. [img]images/icons/mad.gif[/img]



The image thing still doesn't work. here is a link
