What Glue or Resin

[Caer Urfa]

My stantion posts have 4 holes for fastening them to the deck, the 'outside pair' are though bolted through the top wood and grp and bolted inside the hull, the 'inside pair' of holes are only screwed into the wood top and due to wear now do not tighten.
The inside ones 'can not be through bolted' due to internal access.
Is there a good wood glue or resin I can get and pour or pump it into the wood holes and then re-screw the screws into it so it will set hard and solid again?
All screws 6mm dia.
All advise appreciated

If i have it right?
I have the same sort of problem on my boat but i was going to seal the two screw holes and support the stanchion off the bulwalk (sp?) on the side.

I was looking at a fisher and the stachions on that where fixed to the capping rail.
I did think of doing something like that and bolting them through rather than screwing them down

Epoxy resin (Structural Polymers, WEST or International) mixed with a little silica gel and some microfibres. The wood must be bone dry, the temperature not below 5°C but 10°C is better. First apply the resin (mixed with exactly correct proportion of hardener) to wet the wood, then fill the holes with the stiffened (to creamy consistency) mixture. Either wait a couple of days for it to set hard, then drill and screw stainless steel screws in, or insert screw whilst still wet. If the latter, the screw may be so well fixed that eventual removal may be impossible.

Another option is to let in some s/s strips screwed to the timber, then bolt the stanchions to tapped holes in the plate.

You have just give me a thought for mine.

The main problem with mine is water is tracking down the screws and into the boat.

If i was to epoxy in studs would they hold?
The main problem with the stanchions is people use them to drag themselves onboard so i dont doubt it will solve my leaks but are they ilkely to rip out?

The inside screws 'are screwed' to the wood bulwark capping only, that's the trouble, problem is they will now not tighten up due to wear.
Inside the boat due to the shape of the bulwark sides you can not get any more through wood/GRP bolts and nuts which would have been the ideal solution.
Screwing to the wood capping side would entail all new stantions with a custom base.
Pouring in an epoxy resin may be the solution, I did it on my last boat and it worked well but that was direct into GRP only, thats why I asked if a Resin or glue was the answer as this is teak I want to fix into.?

G'day Mike,

<<<if a Resin or glue was the answer as this is teak I want to fix into>>>

Teak can have a lot of oil in it and this will prevent a strong bond, However, you can remove the oil by first drilling a suitable sized hole with a wider base than the top, like an inverted 'V' or bell shape.

Check the material the drill pulls out to ensure it is bone dry, Get hold of an all plastic Syringe from your local chemist and wash out the new hole with Acetone, this will remove any surface oil for about an hour, if you rinse a hole and it more than an hour to get back ti to fill it, wash it out again.

The Acetone will also take up a small of moisture, if you suspect the timber is at all damp use a heat gun, then acetone.

Mix a small batch of Epoxy resin and hardener, mix, now add some Micro-fibres to the mix and stir in till you have a consistency that will not drip off a finger.

Use the syringe into the holes, start at the bottom and pull out very slowly, or use a nail head to push the material to the bottom, the aim here being to eliminate any air pockets.

Also consider getting hold of some threaded tube to take bolts of the required size.

One word of warning:
The above will result in a strong fixing, if the area is stressed it may bend the stanchion, or, rip up part of the teak if pulled out.

Hope this helps.

Many thanks gents it is all good food for thought!
My plan 'B' is to look at some of the handrail clamps available and fasten one to the base of the stantion.
Then look for some sort of an extension so I can add two more screws to the inboard 'side' of the top bulwark wood topping.
The general idea is to stop/reduce the side pull when people grab the stantion from another boat and 'pull it'.
