What is the best way to dry rough sawn discs from a walnut log? I’m trying to make a clock face from a disc and it seems to split very easily. If you cut the disc from green wood and immediately soak it in PEG (Polyethylene glycol) it will normally prevent the splits. PEG is a waxy substance that can replace the water in wood, but remains waxy and can come back out. I have a lovely pear cross cut my uncle carefully preserved and gave his mother. We would like to cut a disk (circular or oval), dry it without any large cracks, and then finish it with polyurethane. For thin, porous wood, the disk can be dried in alcohol.
Drying round cuts from the end of a log, however, is a totally different story, and almost always results in split wood, and not just a small split, but usually large, unsightly, unrepairable and often devastating splits. Kiln drying wood at elevated temperatures also has many other secondary effects as well, such as killing powderpost beetles (a destructive wood pest) in all stages of their development. It is done with wet lumber all the time in Alaska with trees cut processed and used days apart. A slice of wood will always split because, as it dries, the cells collapse and wither just like a dry sponge. Here are a few tips about making plaques, cross-cut sections from Dale, the technical person at Preservation Solutions, which makes Pentacryl.
Wood cross-cut sections or cookies are a popular cut of wood to work with. The more water that is displaced prior to drying, the better results you will have. If the resulting pieces are round and crosscut from the log then we usually call them cookies or disks. This is because as wood dries it shrinks across the growth rings. I recently cut down a large Maple tree from my yard and am interested in drying a cross-section of the trunk to build a table.
Round Cut Tops (almost) Always Split
I often see cookies – cross-section slices of tree trunks – on display. If they are not protected in some way, the wood will oxidize and turn dark itself, not to mention handling it will leave dirt and oils on the sample also obscuring the details of the section. I have seen samples of old growth longleaf pine from south Alabama that were simply cut, dried, and then treated with a thick polyurethane finish. My father-in-law is about to cut down a large Ash tree (on the insistence of a neighbour). A thick piece of wood will take time to dry until you can be confident that it has stopped moving around. Put it someplace good to dry and cross your fingers. I want to use 1 inch thick circular slabs of wood on the guests tables. Does it have to be a cross section of tree? If you cut a circle from a board, it is less likely. First off, just want to say I’m a beginner at wood working and I’m very impressed by alot of the things I’m seeing here. Anyway, in addition to turning blanks, I think I’ll take some cross cut slabs in the 24 to 18 dia to make into table tops, stool tops, etc. PS One other thing to consider, the wood is so wet that water was actually running out of the end grain after the chainsaw cut, if that makes any difference. I have about 2 dozen chunks of wood (large branches cut into pieces ranging from 4 – 10 inches in diameter) I want to dry them out to use as centrepieces for my wedding.
Stabilizing A Cross-cut Section Of Wood With Pentacryl
To dry a big slab of wood properly takes a long time.It might be such a thing as to slobber it up with anchor seal and let it dry slowly over a period of years. Also what is the best way to dry a cross cut section? I’d like to make a table like that from a 5′-6′ diameter round?. I’d recommend doing rough cuts of the coasters while green, and then finishing them once they dry. Thin cross-sections will dry faster and more evenly, so you have the added benefit that the wood is less likely to split. Even kiln dried wood has some moisture in it. Sealing moisture in will still result in some checking, warping or swelling based on external temps and humidity. We found some great info at Woodweb drying cross-cut log slices.
Make a straight saw cut from the outside to the center of the slice. A solar kiln is a cross between kiln drying and air drying. These kilns are generally a greenhouse with a high-temperature fan and either vents or a condensing system. How to Limit Cracking when Drying Wood Discs A discussion of principles and techniques for drying cross-cut log slices with limited cracking. Step 2. Seal the Cross-Cut Wood Plaque by applying a coat of Butcher block oil using a cloth, on both sides. Let it dry for 20 minutes, and apply another 2 coats of it. I was thinking of painting the end grain to slow the drying process. better ideas are welcome. These are crosscut slabs so you can see the tree rings. anybody have a good idea how to dry them so they don’t check? I didn’t read you post close enough. I am not sure about PPG but I know some wood turners will use PEG which is polyethylene glycol.
