So I finally started my first log project. I figured I should start small so I am making my daughter a step stool. I cut the tree down that I am using about a week or 2 ago so it is still wet. (I have been told it is cotton wood) Are there any restrictions to putting a finish on green wood? It has been peeled for a few days so the outside feels pretty dry but if you cut into it at all you can feel the moisture. I plan on just doing some type of clear coat but I wasn’t sure if I should go with a water based sealant…or if oil based would go on ok. Hopefully it will be done in the next day or 2:) Thanks!!

Unfortunately I don’t think it will survive.

Green wood will shrink as it dries and if it can’t shrink evenly will split, warp, bend and crack.

How large are the individual pieces of your stool?

I have been known to take small individual green pieces of wood and put them in the oven for a day or two @ 170° or as low as it will go.

I have also dried green wood in the microwave although that is more labor intense.

the longest is 18 in…i had heard somewhere that the finish would slow the drying process making it less likely to crack…i was hoping that was the case but your explanation sounds more logical. i would like to do larger projects too so i’m not sure what i will do about drying those….maybe i should find someone to allow me to use their kiln for a price. i had a big oak log that was sitting in the garage drying and it literaly split in half so i’m starting to worry about my log furniture capabilities lol.

...oohhh nnooo Shelly, excess moisture is not our friend, unless you’re turning green wood on a lathe.

...warping, checking, cracking, bowing, cupping, twisting, shrinking, splitting just to name a few of the FAILS of milling lumber when the moisture content is too high, not to mention if you were able to coat it with a finish, other than some type of oil, the finish will flake off as the wood shrinks as the moisture evaporates.

Would be best if you research ‘Kiln or Air Drying Lumber’.

One thing to mention….
When I dry in the Nuke or the oven I usually put in twice as much as I need and hope I’ll get enough usable wood back to make the project.

Always cut oversized so you can trim to correct dimensions later, it not only gets smaller around, it will get shorter as it dries.

The couple of times I have used naturally air dried logs I usually end cutting off several inches off of each end. These were whole logs that were allowed to season with the intent of becoming firewood and I rescued them from the file.

Shelly, if you want to build with green wood, do an internet search for phrases like “building furniture with green wood”. There are folks that have special techniques for it. There is a lot of splitting instead of cutting and use of joinery like draw tenons so they can be tightened as the wood dries.

ok, thanks! i was worried about cracking, shrinking, but not so much warping, bowing ect since they are still in log form. i guess i will just glue it up, maybe put some oil finish on it and see how it goes!

Use your oven to dry the wood, about 4 hours at 210 degrees. Check and then another 4 hours if still green.. Use your drying racks, put parchment over them and a cookie sheet under them

Check how they did it with rived wood. Roy Underhill has shown some green ww on Wood wright’s shop. I do not remember the details.
