Been on my to do list since I bought the boat........completely non-structural and teak
(40 years old and well shot) simply bolted though the fibreglass (non cored) topsides.....with nuts on the inside.
I was going to get the Boat yard to sort. But then I got their Estimate - not scarey, but enuf to make me think of putting some effort in and removing the rubbing strake myself and leaving the boat yard to do the more skilled stuff of fixing a new one.
Of course the nuts are well rusted onto the bolts after 40 years - zero chance of getting them all off with a spanner
Boatyard was talking of cutting them flush and leaving 'em in with an epoxy
coating and fixing the new rubbing strake with self tappers. But I am not overly keen on leaving the stub ends inside in place.......
So I was thinking to use a small angle grinder to remove the teak
and the top of the bolt, leaving a stub on the outside of the hull
What has got me stuck is that I can't figure out how to then remove the remaining part of the bolts (I am presuming that their will be at least some which won't knock through)....."drilling out" sounds good, but I have no idea what kit I would need for this
- any ideas? and also not sure how flush I would need to cut the bolts back before drilling........not being an expert with an angle grinder makes me hesitant to cut flush with the hull
.....at least not first attempt
Am quite happy to spend a few quid on tools / kit if it makes my life easier - as I would be happier putting my money
into stuff that sits under the workbench rather than waving it all good bye with the boat yard
