How to dry wwod

[Frosty]

How would you dry some 1 inch marine ply that is encased in fibre glass or does it matter being marine grade stuff.

[TeddyDiver]

How wet it is ? If it's wet throw the inner veneers there's no reasonable way..

[sdowney717]

likely impossible
if you have a vacuum pump, you could drill a hole and hook it up and let it run for week.
under a vacuum water boils, vaporizes and the pump sucks it away.
it depends how well the fiberglass is sealed as to if a vacuum could be gotten on the wood.

Bag the whole thing and hook up a shop-vac. Let it run in the sun. How big is the object?

[Frosty]

How much is a vacuum pump?--you mean one of those pumps that vac out air conditioning systems or is that too strong? Those pumps cant run for a week --can they?

If it boils by lowering the pressure isnt there a chance of expansion.

Its in a bulk head,--about 5 feet high by 3 but only wet at the bottom.

It might have come from a self tapping screw holding an auto bilge pump switch !!!!!!.

[hoytedow]

Just use a regular shop-vac. You can probably find one cheap if you don't already own one. Hook it up to the screw hole. The water can exit through its entrance.

[Frosty]

Whats a shop vac? ok ile google it --back in a minute!!

[Frosty]

Oh you mean a regular vacuum cleaner, will that do it?

[troy2000]

When you say 'regular vacuum,' do you mean normal shop vacuum, or household vacuum? Household vacuums aren't equipped to handle liquids or wet substances. Shop vacuums are; and they're almost ridiculously cheap -- here in the states, anyway.

Well a regular house vac non wet would be able to handle the small amount of moisture that would take a week to come out.

Yes the wet and dry house vacuums are cheap about 30 dollars. Is that what we are all talking about. You saying that would suck out the moisture?

cut it out and replace it ..you know it makes sense .....can you dry out a wet transom ..no ......**** happens live with it .......I do she is called Hilary ..

[Frosty]

There is a difference between wet and rotten.

[hoytedow]

Afterwards you can inject some sodium borate.

[Stumble]

To get enough of a vacuum Yo boil the water off at a reasonable temperature you need to pull around 27in/hg which translates to a boiling point of 115f or so. This is well beyond what a shop vac can pull. If this is the rout you want to go you need a much stronger pump (and one that isn't dependent on air flow to cool the motor. Try a refrigerant pump. The threads on vacuum infusion should have a number of good suggestions that run around $100.

If it is just a small area at the bottom that's wet not rotten, I think what I would do is just drill some small holes it the area 1/8" or so diameter couple inches apart and use a heat lamp close to it and give it some time to dry, after it is good and dry inject epoxy resin in the holes and be done with it. I did it that way on some balsa coring that had gotten wet but was in good shape yet, worked good just took a long time to fully dry
