Wrong bolts?

Shouldn't they have used SS carriage bolts and turned them
the other way and put a little bedding compound around them?

 

ehhmmm, is that a female sittin' there....?

 

Bolts? Thems are legs....I don't see any bolts.

Nor me! some people has strange names for things eh?

 

It doesn't take much to get this bunch off topic!

I think the young lady is about 12!

If it's not a problem, I can post the picture, it was given to my Grand daughter when
she met this young girl, model, when she was in Brazil last summer! My Grand daughter
wants to be a model and they came across this photo shoot and Kayla made friends
with this young lady! They Email all the time now!

 

Carragebolts are about the worst fastener ever made, except those ones that have the little **** on the back of the head to dig in. The titted bolts work better, but still have limited tightening ability, before they tear out the wood under the head and spin helplessly, as you try to remove a stubborn nut.

If they had the heads on the metal bracket side, there would have to be a square hole in the bracket to hold the shank of the head from turning as the nut was tightened and likely why they're mounted the other way, as seen in the legs photo.

 

So I need bolts with **** and square holes and this will
fix the leak?

 

replace the transom, all other activities may be illegal

 

After battling many wooden boat woes I tend to be somewhat more caveman in my approach to fastening things. For the transom I'd be tempted to through bolt the brace with long bolts and large washers...and adhesive caulking.

Now for an ignorant question...what, praytell, is a "titted" bolt? **** pretty much lock my brain into a visual that has nothing to do with bolts...

 

Haven't a clue Chuck but I'd sure like to get my hands on a few!!!

 

i THINK they are bolts,,that the "nuts" have "****" on the "wood side" when you tighten ( or hit with hammer hehe) the bolt it "pulls" the nut into the wood,,,and them "****" are SUPPOSE to dig in and NOT turn,,,,,,like Par said,,,,they tighten good,,,,,but it doesnt take much to "mess em up",,,,loosing them usually means a saws-all,,,,,,,,,,I THINK, thats what he was talking bout,,,,,,but as usual im probably wrong,,hehe

 

what kind of thread is this anywayz?,,, ****,nuts,through bolts,,man ,,nasty people hehe

 

It would be very useful to have carriage bolts with socket heads for allen wrenches, but I suppose it won't ever happen. I use carriage bolts on all my gaff and boom jaws. They work fine (though you have to chisel a little square mortise first).
They certainly are a lot better than brass rod and washers, peened over. Last gaff jaws I used ash and the carriage bolts tried to spin (usually I use substantially harder white oak, but three-inch pieces with curved grain are not easy to find).
If I had my druthers, I source socket head ss bolts, which are easier to set flush, and I'd make flush hexagonal insets on the nut side (using epoxy rather than chiselling), then screw/unscrew from the head side. All this can be applied to other places on the boat, which is why I'm mentioning it now.

Alan;

The boat I am working on has carriage bolts holding the
daggerboard case to the keel. Now you all have me thinking
there may be a better way?

I like the idea that it can be removed if it ever needs to be
resealed. I know I have seen these bolts somewhere so I
did a bit of googling and it dawned on me, they are called
button head bolts!

About half way down the page;

And they come in SS!

Why has my attempt at a funny thread turned into one
that should be in the boatbuilding section?

 

There have been called a number of different things over the years, but "fin head" is the name I remember most.

The underside of the bolt head (not the nut) has a few fins that stick down (****, sharp, pointy ones, like a young . . .), which pierce the wood as the bolt is driven in the well fitted hole or as it's tightened. They can be commonly seen on docks and old boats, but I haven't seen them in a store for years. I think I have a few bronze and galvanized ones lying around some where.

My problem is they can only take so much torque before they begin to spin. With the carriage head there's nothing to hold onto, so you're screwed, hence my dislike of the beasts.

There use to be a manufacture of socket head bolts, which had a button head (an Alan drive, but rounder and bigger pan head). These would be ideal if you could find them.



Maybe BoltDepot . . .

Alan, I'd use blind nuts on your gaff jaws, so you can crank the bolts down good, but no exposed nut. Bung the nut side for a clean look.
