stupid mistake.....any suggestions???

Post by darthplywood » Sun Nov 14, 2010 9:00 am

okay...i'm an idiot...heres what i did:

I didnt sink my carriage bolts in deep enough to account for fairing on the keel. There are two carriage bolts on the keel by the transom and two up where the stem is attached.

The carriage bolts are frozen in place with epoxy and i am finding it difficult (maybe impossible) to get them to budge trying to remove them.

suggestions?

been there too every so often :roll:
heat them up with a soldering iron and it will soften the epoxy enough to remove them

I'd grab a grinder and 'fair' the bolt to shape.

I'm with Billy on this. Heat will soften the grip of epoxy. I used a small propane tourch, the one that recharges with the small cannisters. It puts out a small, hot flame that will do the job. Scarry as it sounds, I didn't even discolor the wood. The bolt will pop out and you can re- countersink. But, keep a water bucket handy as a safety precaution. If I had a heavy duty soldering gun, that would have been my first choice.
By the way, your use of "stupid" mistake cuts many of us deeply. "simple oversight" is a better explanation going forward.
Good luck,
Tom

Hey I am an idiot too :D .

Mine were not sunk deep enough either. They were also never coming back out.

I faired mine down with the grinder, like Iggy said (and my power planer :oops: ). Worked fine.

I think it just depends how "not deep enough" they are for what you need to do.

I got a bit of a different look at this problem.

I use a "Hole cutter" to expose the Carriage bolt head.
Then I'd get a Torque wrench and pull the bolts back out. Epoxy wont withstand the Torque of that Air or Electric wrench. The bolt will come out. Nothing else will change.

Use the "hole cutter" to sink the hole down a bit, and cut off the bolt or get shorter bolts, drive them back in place. Then proceed with the F/glass and other work.

If I'm not understanding what your problem is, please post a photo or two. We'uns lak em pichers :lol:

Thud,

How do you get a hold on the top of a carriage bolt and use an air tool?

The way my bolts went in, I do not think I could get them out if I needed to. The force on the bolts is not the same as just bolting two flat pieces together. The bend at the stem on mine would make it very hard to try to get them out if I could get enough heat on them to soften the epoxy.

Mine were not that much too high so I was lucky and could just grind them.

There's two ways to get hold of them air thangs! :lol:

One:
Use a Dremel tool or your right angle grinder with a thin kerf metal cutting blade.
Cut the "X" in the top of his little round head and use a pretty good sized "Jesus driver" on it. I Have a 1/2" Drill with a lever that put's it on "Chatter" or "hammer" mode.
Just hook im' up, pull the trigger and be patient.

Two:
Involves more tools.
Drill the hole in the top of his little round head and put an Easy-out in there and un-screw him out.

Be careful not to cut or drill so deeply that you weaken the "Head" to "Shank" joint and cause the head to pull off.
Even if you do, you can go on from there all by yourself.

If you had to, you could take the head off, put an electric Drill chuck down on the "Shank", screw him down good and tight, and put the drill in Reverse, and back him right up out of there.

Replace him with an ordinary Cap screw, and when the Finger nail painting is all done, that Hang nail wont show at all.

Thanks Thud. That is why I love this site. All kinds of people thinking up all kinds of ways.

Never thought about I could have just drilled the top off and grabbed with a hammer-drill from the bottom :oops: .

Darth,

Did you make a decision on which way you will go?

Mark all those tools in an unusual place.
Injure the tool so it wont look like a Mark, then take photos of the tool with a News Paper lying nearby.

We are going through heck with Druggies stealing tools.
The Courts just cannot help you if the Tool's not marked.

However......I'd love to rant here.....grrrrrrr

thats a lot of good suggestions (unfortunitly all of them require me to buy yet another tool).

I'll give it a try this week and see what happens!

THANKS (i'll post pics as to how it works out)

You do not need another tool, only care with a heated bolt head. Of course care needs to be taken. But first off, I need a really good closeup of the heads in question. This is not a big deal at all. The only tool that I see that is needed is some finesse. But I will await for a very close to proceed and a rambling reply and possibly my own photo.

I finally picked myself up off the floor and got this fixed. I used a soldering iron and heated the bolts up. THen i tapped them out with a hammer. It worked like a charm! Thanks for all of the good advice! I finished up with most of the fairing and am begining to make my long peices of plywood for the sides and bottom now. I would like to have the hull completely done and ready to flip over by the first of the year.

Thanks again!

Did you re-sink the heads deeper and replace? I think I'd feel better doing that at that joint.
