That's my story and I'm sticking to it!
I am surely ready for something E-Z to do on this cotton-pickin' Jiip!
After squaring the tub on the frame, we were able to only mount two bolts. We were able to drill two more holes, but the bolt heads will not sit flush on the floor, they fall on a molded edge. No big deal... I'll notch it out and square it off with glass, and it will be perfect. I removed a small plug around the bolt head, the area I intended to square off, and exposed debris! Debris?? How did debris get between the layers of glass? So I removed some more flooring. Holey Moley... the factory wood is completely gone! It looks like termites ate it to pieces! Alright... I can handle this. I have built a couple of boats over the years. I can repair, replace, reinforce glass, but C'MON... I need to breathe.
If you are reinforcing glass with wood, JUST LIKE ALL THESE FG REPLACEMENT PART MANUFACTURERS, keep in mind that #1 Pine is great structurally, but doesn't give you crap for longevity. If you use untreated wood, the very least you should do is paint the entire piece with activated resin. BETTER, use Ash, and also paint it with activated resin. Ash has more resistance to moisture. BEST, IMO, is PT wood. I know an old guy that did hull repairs at a marina, and he told me PT and FG won't stick. The last boat I built I fished out of for 15 years, glass over PT plywood, with virtually no problems. So Humbug! I guarantee it will last longer than untreated lumber. Moisture will get through the body mounting points, especially if you play in the water. Page 282 of the new 4WD Spring 2011 catalog shows a pic of a FG tub, boasting the use of #1 Pine. Not 4WD's problem. It's the MFG. But you're gonna pay ~2 grand for that tub.
Sorry... I'll get off my soapbox.
Here are some pics of the process I used to remove the floor panel. My wheel on my die-grinder broke and hit me in the left cheek and tip of my nose. Blood was running down my face. My wife cleaned me up... just a couple of small scratches. Totally surprised me. WEAR FACE PROTECTION AND DON'T KEEP YOUR HEAD OVER THE CUTTING WHEEL!
Floor panel (plug) removed. Showing the completely and totally ruined/rotted/destroyed original pine! I don't know the tub manufacturer, nor do I know what year it was made.
Virtually, I vacuumed up the crud. I did not have to scrape or pry any of it. It was like dust and old paper. Glass has taken on the appearnce of the wood.
Showing the plug next to the hole. I cut through the tub in a couple of areas, but that is no big deal. We will be flipping it over and glassing/reinforcing in many areas.
Just showing how the plug will go back in the hole when we are ready. First, we have some wood work to do on our fiberglass tub. Wood work!? Sounds stupid! Essentially, it's a boat with wheels!
Gotta get back to the shop. I left Clay to remove the other side. Hope he ain't cut that joker in half!
