Teak lumber

[Chotu]

aside from repair as suggested, you will find lots of teak at marine consignment and used gear stores on the cheap.

If you want new, boulterplywood.com has tons of it.

Thanks as always.

Just to throw a bit of pedantry into the mix of good responses:
1. My nonchemist understanding is that with most of the single part glues, the surfaces must be nearly lapped perfect and tightly clamped as the bond is best when one molecule thick. With multipart glues, such as epoxy, a thicker glue joint is preferable to allow necessary cross linking for building strength in the joint. The latter is easier to achieve success, though for some, aesthetics may suffer.
2. I have used epoxy or resorcinal exclusively for joints in teak. Surfaces should be fairly smooth so as to avoid snagging he cloth used for wiping with acetone. Glue should be applied ASAP after wiping/scrubbing the joint (allow acetone to flash off). No joint failures in 30 years.

3. Consider that gluing smaller widths many times has the advantage of longevity over using wider boards. Usually not so much problem with teak, though it can occur that a board may warp or crack; depends on how it was cut and how it is fastened, and whether the load or weather stress is applied to face grain or edge grain. A good glue joint can be stronger than the grain. Gluing narrow pieces to make a wide board allows for reversing the grain direction of the pieces to reduce chances for warpage in finished product. Vertical use (the sides of box) are will receive less weather /solar stress that top. Epoxy is subject to UV degradation, so minimize joint width within limits for good joint. After all those words, consider that you will have two long sides, two short sides and an intermediate baffle, all of which should reduce the chances for warpage all round. Dovetail joints with gussets inside is primo. Rabbet joints with gussets is good.

4. When it comes to availability and choosing width: Within a species, Price, width, quality; choose any two.
5. In distant past, someone suggested (some other forum) using one of the polyurethane adhesive sealants such as 3M or Sikaflex instead of epoxy. Have not tried.

As another post suggests, resourcinol is the traditional adhesive for this type of application. I edge glue all the time without special edge prep - just a clean cut on table saw. Also as suggested by prior post, multiple strips is more directionally stable than a single wide plank. If you have a router, you could rabbet the edges and glue together which would really add strength, though not sure it's needed. Would likely require a lot more sanding to get it fair.

OP may want to include a location. There are often regional hardwood stores to be recommended. Someone mentioned Miami - there's a great one there. Name escapes me. MacBeaths in Berkeley CA comes to mind. I'm sure there are others.

Good luck

I've had a quick look through the comments but can't see where anyone mentioned there are many types of "Teak". You ask where you can buy it but to answer that can you be more specific and tell us what type of teak you need?

The botanical name of Teak is Tectona grandis. This species of tropical hardwood belongs to the family of flowering plants, Lamiaceae. Real teak wood is yielded from old-growth forests of South Asia. The teak wood that is obtained from plantation forests is called plantation teak wood.
The highest quality teak wood is Grade A teak wood. The timber in this grade is obtained from the extreme center of the log (heartwood) of a tree that is fully mature. It is recognized by a uniform golden-brown color. It has close grains and a glossy surface which is oily to touch. It has a high quantity of natural oils that are responsible for the outstanding resistance of teak wood to outdoor elements. They protect it from harsh weather conditions and repel insects. It is very pricey because it is only fifth to one-quarter of the entire log.
Grade B teak is obtained from the outer heartwood. It makes to about one fourth to one-third of the entire log. Thus, it is lesser in price as compared to grade A teak. It is lighter in color. Grains are uneven and the wood has less shine. It has a very small amount of teak natural oils. It does not withstand extreme outdoor conditions and needs certain protective treatments.
Grade C Teak is an inferior quality of teak wood. The timber is obtained from the outer sections (sapwood) of mature logs of immature trees. It contains near to no natural oils. The color is extremely uneven. It gets damaged easily because it is soft.

Types of Teak Wood On The Basis of Origin:
Burma / Burmese teak wood
Popularly called Burma teak, it usually a grown native to Myanmar or Burma and goes through a growth time of over 50 years. This is considered some of the best variety of teak wood and comes in golden shade teak wood color, elegant wood grain and contains teak tree oil inside.
Indian teak
This is a famous native teak wood from old-growth forest and has properties in par with Burmese wood. Indian teak wood is out of supply in international market because it has lot of demand within the country.
Thailand teak:
This is considered superior in quality to Burmese wood as it originates from the best surrounding and growth habitats for teak wood trees. Thai teak wood has excellent strength and superior quality although is not easily available in international market.
Indonesian teak
Also called the Asian teak wood, this takes over 30 years growth period. The growth conditions are extremely suitable and hence helps the best quality of plant growth. The wood has wider wood grains, average oil content, it is light brown in color with a slight grey hue and more sound knots.
African teak
This wood planted in Africa takes a 15-25 years of growth time. This has less oil content and hence it is slightly less durable and stable compared to the above types. The color is light brown in color and has some cream color of sapwood. This has wood grains and wide and full of sound knows too.
South American teak:
This quality is similar to that of African grade and in fact even today there is a slight confusion distinguishing the two types even in market.
There are 4 major varieties such as the Chinese teak wood, Brazilian teak wood, and south American Teak wood which are not originally teak yet look very similar. Brazilian wood has high oil content and is durable and water resistant whereas Chinese teak is processed for hardwood flooring and is extremely durable.

Yes, probably works better than epoxy with teak for close fitting joints, one of the truly great adhesives, just not as versatile as epoxy.
