Re: Centerboard Cable thru hull question.
|
First, congrats on the boat! ?While I would agree with Scott regarding assuming the worst, I might not be quite as categorical. ? Bronze fittings, if they¡¯re of good quality, last for many decades; that¡¯s a main reason they¡¯re used. ? The telltale sign of being too far gone is a pinkish cast to them. ?That¡¯s usually caused by the bronze de-zincifying, usually caused by galvanic corrosion. ?If they¡¯re headed that way, then yes, by all means, replace them. ? But if not, and they appear in all ways sound, I¡¯m not sure that removing them just because they¡¯re old is really necessary.?
As to the 4200/5200 comments, I¡¯d say first, how would you know? ? Or at least, how would you know without trying to remove them? ?I¡¯m personally unaware of there being a longevity problem with either of those two products. ?And as to the 5200, well, there¡¯s a reason it¡¯s called ¡°The Devil¡¯s Glue.¡± ? I can¡¯t recall where, but somebody markets a solvent for it, but without that, good luck removing anything bedded in 5200. ?But I have also read that Tartan DID use plain pipe just fiberglassed into the hull for certain applications, i.e. NOT a thru-hull, just a glassed-in pipe. ? That¡¯s bad enough, but since it¡¯s almost impossible to find small bronze, as opposed to brass, pipe, if you found any of those, I¡¯d suspect they might be brass, and yeah, they should go and be replaced with a proper thru-hull. ??
I¡¯d also add to your checklist, the rudderpost heel fitting, all the way down there at the bottom. ? I have encountered one which was not only extremely worn, making for a lot of sloppiness; but was also cracked all along one side! ? ?The rudder and its post are pretty heavy, and if that heel fitting ever gave way, I wouldn¡¯t count on the tiller fitting being tight enough to keep it attached to the boat, and ooops, there goes your rudder. ?

Should have mentioned it to Christopher as well but the forum has a little database feature, and there's an "Owners list" in there: /g/T27Owners/table?id=14720 Please feel free to add yourself and your boat? (I'm 1965 hull #93). There's going to be an echo in here, but fiberglass epoxy layout. Gently sand the bronze to get the oxide off (I keep a roll of plumber's sandpaper cloth handy... the cloth backing makes it a lot easier to use for hand sanding on fussy handles) and expose and rough up fiberglass on the top of the centerboard trunk for at least a few inches around.? Scrape or grind off the old filler used to seal that. Clean up particles with a clean rag and solvent, then do some fiberglass and epoxy layup, maybe to 1/4" thick, going between the trunk and pipe, replacing whatever was there (polyester filler maybe?). Since you're currently on the hard, it's a good chance to remove thru-hulls you don't want and rebed ones you do.? If you don't know when that was last done, assume the worst.? Original bronze should be replaced and anything bedded with 4200/5200 should be rebedded.? It's also a chance to service the stuffing box I guess (still have a dripless seal, which requires more maintenance and is even more impossible to service on the water).? Apologies if this is something you're already well aware of. Cheers, -scott On 4/17/22, dfeatherstone90@... <dfeatherstone90@...> wrote: > Hey all, just picked up a 66 Tartan 27.
