I designed 10 meters of hardwood frames floor to ceiling in three sections, each with full height double doors fitted with a very nice blue tint glass. The frames were made by a fellow a few km north of Cha-Am who's apparently the only framer many chan mai will deal with. Select blemish free and even coloured timber yourself including all mouldings, give him an accurate drawing of what you want. He will not install or give names of carpenters, you must have your own who can make accurate long cuts on his table saw at your home. I've had carpenters turn up with virtually no tools or skills and they don't last long.
Once installed with doors functioning and glazing (5mm and up, beveling is worth the extra cost) in place the wood must be finished after proper sanding with at least 3 grit sizes. I use tung or linseed oil depending on availability and the type of job interior/exterior mixed 2:1 with liquified beeswax/paraffin wax (heat it in a double boiler) then add a fair bit of mineral spirits. Get these components and do some experimenting, it's quite easy. The results are outstanding. I see wood shops plastering urethane and sparkly varnish on their stuff and wonder what they know abut wood. You could also add to the formula a preservative to kill termites and bugs, an AV blocker and a fungicide. Adding oil colours to the mix is easily done. Apply multiple coats, 3-6, it's as easy as wiping down the kitchen counter with a few days curing time between coats. Never strip or paint again. Refresh twice a year.
The beeswax acts as a water-repellent greatly helping the stop swelling and sticking windows and doors and the oil acts as a preservative. Wax alone works very well.
I'm midway stripping several doors urethaned a few years ago that have always annoyed me, done when I knew nothing about wood and the finished ones are looking gorgeous. Approx 20 man hours to strip and prep each door and worth every minute. Take a look at what they're doing here, a 20 year test on wooden window frames. http://www.historycolorado.org/sites/de ... s/1113.pdfhttp://en.wikipedia.org/wiki/Drying_oilshttp://www.youtube.com/watch?v=4BAHx0KBpT4
Use the formula on all your tools to prevent rust, on handles for better grip, waterproof clothing, apply to engine components on your car (I'm working on a mix that includes a degreaser to clean and protect engine stuff in one application, don't know yet), house door locks, leather etc.
