OK, let's get the joke out of the way. Gotta be one here, bedding a screw, use a wench, I dunno...

Anyway, I attached my tiller extension socket to my tiller last night with two wood screws. I plan to put a Can-Sail Tiller Lock on my tiller this weekend, which uses two screws as well.

I got to thinking about it: should I be sealing these screws somehow, to prevent water from getting into the tiller? If so, how?

Thanks in advance for the help.

I think buying a new tiller every three to five years is a good thing.

To keep moisture out, I use neoprene washers on the bolts securing my tiller mounting plates. I don't know if they could be used in your application.

Actually, I agree (let's say 5-10 years), but the correct answer is ABSOFRIGGINGLUTELY. See my reply to Dan in the Epoxy thread--it mostly applies.

I find that tequilla and a large tool work best. Sometimes oil helps too.

C'mon Kevin, you can't post a subject like this and then think no jokes are coming.

Dave,

I read your reply, but I am wondering how to do this with a screw, not a bolt. If I fill and oversize pilot hole with epoxy, then redrill the hole after the expoxy cures, will I be able to get the screw in? Will it hold like it would with wood? (would with wood, man this thread is going to be full of jokes)

Maybe a new tiller every 5 years...

Randy,

I am actually suprised there aren't more so far... :-)

Has the association ever had a single thread that contained the words, bedding, screw, wench, wood, tool, oil, tequila, extension, moisture, mounting, and ABSOFRIGGINGLUTELY??

I'll stop now

I contacted Catalina a little while ago about replacing bolts in the rudder pintle, and they told me they use 3M 4200 for bedding screws.

Hope that helps. I'm not clever enough to come up with a witty way to say it!

I'd suggest some sort of thin bedding goo, such as 3M 4200. The way to use epoxy in this situation is to drill the screw hole, be sure it's the right size for the screw (or visa versa), coat the inside of the hole with as much unthickened epoxy as practical without it oozing out and making a mess. Install and tighten the woodscrew while the epoxy is still wet.

If you ever need to get the screw out, there are a couple of options. One would be to apply a very thin, tough lube to the screw befor installing it. (Axle grease wiped mostly off, heated wax, be resourceful.) The other method is to heat the head of the screw with a soldering iron when removing it. These methods can of course be combined.

Epoxy + heat = no bond. If you can get epoxy hot enough, it will release it's hold on whatever it's stuck to.

That said, I'd use Leon's method without the lube and worry about getting the screw out later if necessary using heat.

Mix up some west system and drill almost all the way through the tiller at a size 1.5 that the diameter of the screw. Fill it and let it cure.

Then tap the holes with the appropriate drill bit and there is no need to grab any washers. Ideally however you can just go with one of these


and you'll forget about why you even needed a tiller extender.


Though the wheel in this case is really small

IMHO: Using 4200 to bed the screw is a good idea.

"Has the association ever had a single thread that contained the words, bedding, screw, wench, wood, tool, oil, tequila, extension, moisture, mounting, and ABSOFRIGGINGLUTELY??"

Heh. Over on SA this topic would have 10,000 posts by now... none of which would have anything remotely to do with boats.

But Clam, Where else can you correctly use the word Asshat, douse the downfuC$#r, and blow the guy in a sentence.

I almost posted a thread on SA about a name fo the new boat - but then I got wise.

Kevin--you really got something going here... Frankly, in a tiller, I'd drill a normal hole, fill it with caulk, put a little caulk on the fitting, and screw it on. These laminated tillers don't last forever regardless--eventually a little moisture gets in around the mounting bolts, and then somebody slips and sits on the tiller...<b><i>crrrrack!</i></b> I seriously would replace it at least every 10 years--for .6 boat unit, it's good insurance, and the new one looks great.

To get fancy, you overdrill, fill with epoxy, coat the screw with spray-on furniture wax, set it into the epoxy, and let it cure. Then you back the screw out (leaving perfect threads) and attach your hardware. But I'm not convinced that oversized hole isn't going to compromise the strength of the tiller, even when filled with epoxy. (Some would argue it makes it stronger--I dunno...)

STAND CLEAR... BLOW THE GUY... HARDEN! HARDEN!

I installed the Can-Sail a few months ago. Maybe I didn't go to great enough lengths, but I just predrilled the holes and filled them with lifecalk and screwed them down. Took about three minutes. I do use a tiller cover, which should keep some moisture out, but I think it will hold up for a long time.

bedding screw and a wench etc? HMMMMMM. A couple years ago I tried to post a response with the name of a local lake, and my post was rejected...the offending word: Minnewanka.
What's next, advertising?!?!

Hmmm. I guess you have stock in a tiller corporation (Troy-Bilt?).

As far as I know, mine is original to the boat (1985). It's kept covered in the summer, and in the garage in the winter, and I put a coat of varnish on it every year.

Which means this will be the year it splinters one windy day.

I replaced my tiller about five years ago. This replacement tiller is kept covered and it winters inside my garage. I don't see any reason to replace it anytime soon.

Mine looked perfect until it cracked from the butt (fuggetaboutit!) along the lamination by the holes between the mounting plates. I lashed it with some rigging tape and completed the trip.

There is much more pleasure wrapping leather around the helms wheel than bedding a couple of screws in the tiller...

You know, I get sick for a couple of days, and see a really fine thread has ensued. I knew I could count on you guys...

Back to bedding...
