Yep been done many times for other uses.

Re: Tool for removing nuts on VERY long keel bolts

I would cut them IF I dropped the keel, easy to do it properly then.
I don't buy the extra length for alignment idea, things are either lined up or not - an extra 10" of length won't change that. In fact I'd say you could be more sure of your alignment re-installing a keel with shorter studs.
Some good ideas here for extension sockets, it's what I'd do.

Re: Tool for removing nuts on VERY long keel bolts

If you guys read the first post, it looks like the nuts go way down into a narrow bilge... say 4-6" across... if the long studs aren't obnoxiously intrusive, I'd not cut them off...

I have 1 stud that is about that length... the rest being the normal couple inches of available thread for the nuts... While being a PITA to to have a "special tool" for 1 stupid stud... it is a godsend for keel alignment, being able to lift the boat 10" off the keel, and drop it back down without having to find the stud holes again...

Make the pipe socket...

Re: Tool for removing nuts on VERY long keel bolts

How did Irwin tighten them upon first installation?

You may need to search for very long extensions.
Pass through sockets? Thanks for that - Ive never heard /seen of these. I use ratcheting spanners a lot.

Re: Tool for removing nuts on VERY long keel bolts

Possibly the bolts are that long to facilitate drawing the keel up with the bolts. I'd hesitate before cutting without knowing why they are so long.

of course... if that much thread is covered in rust (needing to replace the long threaded sections anyway) when you try removing it there will be a strong incentive to chop them off flush with the nuts.

***********

The special tool or making the super extended deep well socket using pipe sounds like the answer.

Re: Tool for removing nuts on VERY long keel bolts

I have made several sizes out of black iron pipe, 2lb mall, and an acetylene torch. Not difficult to beat the hex in the pipe. Doesn't have to be a precision fit on the nut.

Re: Tool for removing nuts on VERY long keel bolts

Might want to think about the fact that the long threaded bolts you have, may have backed out of the keel. You should find out how long of thread ingaugement (sp?) in the design of the keel mounting. My 2 cent bet, is the keel threaded studs have backed out of the keel and now you have long studs showing in your bildge. Could be hanging by just a few threads in the keel. I would seriously check for this condition , as it cares the heck out of me.

Good grief: you mean the nut is at the base of a 10" bolt? Good luck. Do not cut of the bolt since it probably is meant to allow removing the underlying part of the bolt from the keel. Contact Snap-on, they may have a special tool for this purpose. Would be fairly easy to design one.

I've tried a box end wrench and there simply isn't enough room in the bilge to turn it more than 1/16th of an inch. Anyone have any suggestions or recommendations?
jeepbluetj has the correct idea -pass through socket, socket wrench, and extension(s). Figure out the correct socket size and type (SAE or metric) by slipping on ordinary ones until you get the correct size. Then use Google (or other search engine) to try to find sources for the individual pieces - unless you want a set. In addition to the ratchet wrench (which I strongly suggest at 1/2" minimum, with 3/4" if avaiable being probably better) and the correct socket, you will need extensions long enough to be able to ratchet effectively, or perhaps uses a breaker bar for the necessary leverage. It is also possible the tools can be rented or borrowed (from a local yard).

Re: Tool for removing nuts on VERY long keel bolts

I didn't know about Pass-Through sockets or Crow's Feet wrenches so I truly appreciate the links to info about these tools. When all is said and done it appears to me that making a custom 10-12 inch deep socket is the best way to go. Cutting the bolts would limit the distance that the keel can be dropped to do keel joint repairs on-the-hard. As well the Pass-Through and Crow's Feet tools would make proper nut torqueing difficult.
Many thanks to all who contributed.

Still think you should see if there is a tool you could buy that has the strength and exact fit to what you want to do. Making your own rig may result in stripping the outside of the nuts, bending under torque, and basically falling apart into the cavity.

And yes, do not cut the bolt shaft. Would make it more difficult to align the keel with the hull if you drop the keel. Meanwhile soak the nuts with penetrating oils. A daily spray should do it.

Re: Tool for removing nuts on VERY long keel bolts

Lot's of good advice here. You may need both pass-through socket and cutting the bolts to a shorter length depending on how deep the keelson is.

Pass through socket and extension will do the trick. The bolts are that long for a reason.
