Samsom Posts

Im replacing the two Samson posts on my Krogen 38. They look to be mahogany, lots of rot at deck level. White oak is the wood of choice if memory serves me, I've been trying to locate 12 quarter WO to no avail. Most of the folks I talked with seem to think it doesn't matter whether its white or red, black. I know that anything other than white will rot in short order. Anyone have any thoughts on other woods that might serve? I was also thinking about laminating some thinner stock with some splines and epoxy. Thoughts?

Re: Samsom Posts

Have you tried these guys for sourcing your oak?

If they don't have it I'm sure they can recommend. Mine are apitong, but I'd go with any outdoor rated hardwood. I painted mine with interlux perfection; they're great.

Re: Samsom Posts

Red oak will rot fairly quickly. It doesn't have to be oak, however. I am building a 34' schooner, and the samson posts [one each end of the double ender] will be 6X6 douglas fir. They will outlast me.

Re: Samsom Posts

Laminate out of white oak is good, no splines necessary (if you use quality epoxy properly). Really hard woods are good for Samson posts, due to chafe resistance. I'd use Ipe or Purpleheart. The latter is more and more available and affordable. Looks great too.

Re: Samsom Posts

I would go with apitong if it were me, hard as a rock, extremely rot resistant, and fairly cheep (its often used for truck decking) Our samson posts are aiptong and 30 years old. I just pulled them recently when I rebuilt our bowsprit and they look as good as new. If you can't find 12 quarter you could always laminate. You may want to give Duke from New England Naval Timber a call if your still looking for 12/4 white oak (860) 693-8425 (i think)

Re: Samsom Posts

I would think maybe teak can be used?

If I am wrong, pls let me know why teak is a bad choice.

I ask as our cleats have teak bars.

Re: Samsom Posts

Teak is very nice for most applications but extremely expensive. White oak would be great if you can find it locally. Purple heart is really great as has been pointed out. I've got a lot of ironwood around here and I think I'll try some of that.

Re: Samsom Posts

I hope I can spell it, but I used some eucalyptis?? for the samsom posts on our colvin, hard as the hubs of hell, and a bugger to work! But it wears like iron and never seemed to rot any in the 28 yrs we owned her ! Just a thought

Re: Samsom Posts

Thanks for the input. I like the idea of purple heart. May have found some white oak for $6. a foot rough. We have but one hardwood outlet here in southwest Florida, that being ALVA Hardwoods. They're only open for business in the winter. I don't blame them If I could get out of here for the summer I'd be history too. Again, thanks all.

White oak is fine if you're going to paint it, I might avoid it if you are going to give it a natural finish like oil or varnish. White oak will develop black stains that cannot be removed when it gets wet, which it will since its a Sampson post.

Teak, Purple Heart, and any of the others are fine if you like cutting down the rainforest and have wads of cash laying around.

Alternately, you could use local (to North America) and sustainably harvested Back Locust as has been a part of the American boatbuilding tradition for hundreds of years. It's denser than teak and has great rot resistance, Abe Lincoln used it for fence posts. You can leave it unfinished and it will turn silver like teak but not rot.

Or you could just keep cutting down the rainforest.
