What a deal...oops ... chapter two

[dbergman]

Well after an unbelievable amount of grinding glassing and custom trimming, I'm ready to build two seat bases and after I glass them in, lay the Nautolex flooring. It was at this point I'm planning on mounting the two pedistals fore and aft on the reinforced decking. <br /><br />1) Am I OK to just drill the holes, pore in epoxy and screw them down with SS lag bolts or should I drill an oversized hole and fill it with epoxy, a nut and waxed bolt? Any thoughts?<br /><br />2) I went out to view my magnificent work and lo and behold I saw what appeared to be two screws protruding from the bottom of my hull. Two problems, one I think they have epoxy resin in the heads making the removal difficult and with my terrific job of putting the floor in, there is no way to get at the inside of the hull. Should I grind them down from the outside and fill with filled (thickened) epoxy and glass over it, use 3M 5200 or whatever?<br /><br /> http://www.shareaproject.com/manageProject.php?p=223

I have no idea what the correct answer is, but I would do what you said.

Re: What a deal...oops ... chapter two

Ouch!!<br /><br />1. Either method will work, but your second idea is close to (as near as I can tell without seeing it) my preference. What you are doing is mounting a "blind" Stainless machine nut that stays permanently mounted. That's preferable to me.<br /><br />2. If you merely grind down the protuding screws, I think you'll be doing more repairs later. You'll be grinding flush with the Outside, so the screw will still be into and contacting the hull inner surface. Over time, vibration alone will cause the screw to distort the hull at that point and cause it to fail ... again.<br /><br />There is no easy fix for this one that I can see. The protruding screws must either be removed/replaced or enough ground/cut away to clear the hull inner surface by at least 1/2" at a minimum ... more clearane would be even better. <br /><br />Again, I don't know the precise situation, but remember that your hull will flex ... maybe not much, but over time those screws could come back to haunt you.<br /><br />All this is in my opinion, of course <br /><br />By the way ... I couldn't locate you at the Shareproject site so I don't even know what boat we're talking about. Do you go by a diffrent name there?<br /><br />Good luck ...

O.K. .. I searched for your previous posts and found your boat ... my opinion stays the same.<br /><br />Nice boat .. I DO wish you luck.

Re: What a deal...oops ... chapter two

dbergman,<br /><br />1) Just saw at west marine, stainless toggle bolts (like the picture hanger kind that expand when you push them through the hole and then you tighten them, only bigger and stronger), that may work as well as your blind nut.<br /><br />2) Like pogo said, ouch, you could leave them, they are below the water line and may not be seen as often as the topside, you could cover them with 5200, this of course is an ugly patch. Another option would be to remove them, you could "core" with a hole saw. Any way you go about it is going to require you patch and paint the outside, unless you can remove them from the inside. Core around the heads and get out your vice grips. Heat will melt epoxy, but now you may be hurting other pieces around the screws. If it were me, I would be digging around the heads to get a grip on them and get them out, then fix the topside, and touchup the bottom.<br /><br />Peace.<br /><br />Ed.

Re: What a deal...oops ... chapter two

I got all four out, drilled the hole slightly larger to get a clean and unfractured hole and am debating using an 1 1/2" hole saw thru the wood only,install filled epoxy solidly into the cleaned up hole thru the hull and apply a small epoxyed 6 oz patch to the inner hull and outer hull followed by filling the hole saw vacancy with thickened epoxy before I glass the whole floor. Does that sound right? Or should I forgo the hole saw part?

Re: What a deal...oops ... chapter two

dbergman,<br /><br />That sounds like a plan, the only sugestion I have would be to keep your hole saw piece and epoxy it back into the deck, I have done this before, especially when I am glasing over the area anyway, it saves filler and you don't get the "sag" where the hole was. I wish I had done this in a few places on my rebuild, you can see the dents, if you look hard.<br /><br />Peace.<br /><br />Ed.

Re: What a deal...oops ... chapter two

I lost my internet connection for several hours...sure wish I'de seen your idea of epoxying in the core.....i already filled it and it has already sagged. I'll add some more filler before I glass it. I have to go back to the store for more epoxy to finish the job anyway ...all it takes is time and money and time and....well don't get me wrong..I love this job.

Re: What a deal...oops ... chapter two

Where is a good source for the stainless lags, rosettes, bolts, nuts and washers....Does Home Depot or Ace or maybe Lowes carrry that stuff...

Re: What a deal...oops ... chapter two

drill it out larger, dry it out (very good), wet out the hole, then pour in thickened epoxy... coat screws and plate with wax if you want it removeable.
