This is a set of coasters I made for my sisters from silver beech kindly donated by deltxguy.
the interesting thing about this set of coasters is that they did not check!
The method used to prevent the checking was noiling, and it worked very well. however, there was slight discoloration due to tanins in the bark that were dissloved in the water, and it seems that the grain is less “sharp” than on unboiled pieces.
I have since also used microwaving and it also worked great. even better is some respects (you get instant dry timber). the success rate of microwaving was about 90% (that is, one piece out of 10 checked, and i suspect that it was checked beforehand).
finished with denish oil and poly

Coasters look good. I would lik to know more about micowaving. How long do you leave in? On high?

i have followed the instructions on http://www.woodisfun.com/microwavedrying.html.
basically, you put your stuff into microwave proof plastic bag, put it on high until the bag inflate, take it out, take the wood out of the bag, let it cool (3-5 minutes) and wipe dry the bag. repeat 3-5 times until its dry (i used the scientific method of knocking on it to check for dryness but i am almost sure there are more precise methods)

These turned out really well! I can confirm that without boiling or microwaving, that these checked. I tried making a few myself – using the same wood from the same tree, so I think it was a fair comparison.
Here is one source of information on boiling green wood, from LJ’s own SteveRussell http://www.woodturningvideosplus.com/boiling-green-wood.html

sorry about misspelling your handle… i always think its a short for delta x guy. too much calculus in my life, i guess.
the main difference between boiling and microwaving (other than smell in the kitchen, drying time and colour) is size and scale. i would definitely use microwaving for small items but for larger pieces of wood or large amounts boiling is the only option.

its just what goes easily into your microwave. you can’t really dry a 30 cm diameter log in the microwave or dry a 80cm slab this way. however, you can boil these with some effort. in my microwave i would guess that the biggest thing i can dry this was is about 20×20x20. also bear in mind that these were thin slices, so they microwaved fast. i haven’t tried larger pieces yet but i suspect they will take a bit longer.

Thanks for your reply. I have some green maple I want to carve a few bowls. It sounds like that will be the best way to go.
