We have a Freedom 39 cat-rigged ketch. The bolts on the stainless
steel angle brace at the base of the main mast have corroded and
broken off, leaving stubs stuck in the mast. The stubs are too short
to grasp and are screwed into nuts inside the mast The nuts may be
captive. It does not appear that the nuts are accessible without
pulling the mast. We have looked at the identical arrangement on our
mizzen mast, but it does not offer solutions. Has anyone had
any experience in removing those bolts without pulling the mast?
Thanks.
When I bought Ketch 22, there was no angle brace on the main mast.
Instead, I had a bolt that went thru the main, and was aligned in a
slot in the mast step that prevented the mast from rotating under
force. The mizzen on the other hand had a stainless angle bracket, as
you described. I’ve since added an angle bracket for the main. It
was a requirement for the Pacific Cup.
I suspect you’ll have to pull the mast if the situation is as you
describe. Maybe you can lift it enough to get a hand under and inside
without removing the mast completely from the hull?

My 33 has pins (ground down smooth bolts)
threaded through the mast step into holes in the mast. However, I believe
someone posted pictures at one point of a split stainless ring (from garhauer I
think like the ones used to mount radar on the mast without drilling holes)
around the mast with tab and hole to attach a turnbuckle then the a cable to
the mast step. Certainly looks good for keeping the mast tensioned down, I
would also think it would prevent mast rotation but that’s just a guess.

There’s a method to remove broken studs. Breaking studs happens often
with enginehead overhauls. Drill a hole in the end of the stud and use
a special tool, a broken-stud-extractor, to turn out the studs. These
stud extractors are sold in mechanics shops and are available in
different sizes for different sized studs.
I did it several times and it’s do-able, although not an easy task.
Make sure the studs are prepped with ‘crawl-oil’, as we call it here.

Unfortunately there is not enough room in the anchor locker where the
mast is located to use an extractor. To determine the problem, I had to
use a mirror. Then I used a small digital camera with a flash. That
provided images and clarity that were not available otherwise. One
possibility is using a right angle drill, but even then space
constraints are an issue not to mention keeping the drill centered on
the bolt since it cannot be seen.

No matter what, please remember to carefully file a flat at the end
the broken stud, and then center-punch the EXACT center of the stub
before drilling for the EZ-Out. I have found that this is easier if
you start with a very small diameter drill bit (cobalt alloy is best)
and then enlarge the precisely placed hole with the larger bit for
the EZ-Out. If the EZ-Out method fails, you can drill out the broken
stud, using progressively larger drill bits, until only the threads
remain, and pick out the remainder of the threads. Herm

If you have no room to drill a hole in the stud for the EZ-out,
perhaps you can get a hacksaw blade in between the mast and the mast
ring to saw the stud off? You can buy handholds for hacksaw blades
that leave one end of the blade free.
If everything else fails, you can perhaps saw off the mast just
above the mast ring. You end up with a mast one inch shorter than
before.

Try a Dremel tool with carbide burrs. You’d be surprised how fast it will do the job
