Cutting Up and Using a Hollow Log For Woodturning Projects
As a woodturner I’m always looking for new sources of wood for woodturning as well as new ways to turn pieces of wood or logs that one might think is better suited for the burn pile!
I hear chainsaws running in the neighborhood, I hear wood chippers chopping up branches and it drives me crazy if I can’t get there to see what type of wood I might be able to snag. I see trees that are being taken down or are down laying along side the road and I want to stop at each one ….looking for those perfect bowl blanks ๐

I even watch TV and in the scenery there are trees that are crooked and gnarly and I think …..if only I knew where that was and could get there! I guess you could say I’m a little sick….. woodturning sick that is ๐
My son put up a pole barn and had to take down 8 giant oak trees. Although we saved a lot, much of the branches were sent to the chipper and just about anyone who stopped by and wanted a trunk could have it. He wanted his yard nice and neat and I know he thinks I’m just crazy. If I can’t turn it, I burn it ๐
Hollow Hickory Tree for the Mill or
Cut Up into Bowl Blanks
So, he brings down a 3 or 4 long trunks, 10 or 12 feet long. They were all solid on the small end but 2 of the bigger trees were hollow at the thick end. The wide end was close to 24″ wide, I could have gotten some awesome hickory bowl blanks but over half of the diameter of the tree was rotted through. Very disappointing to see most of the tree from center out was rotten.
Still…there was some good firewood in the rotted pieces, they would be easy enough to cut and split. So I just figured it would be fire wood. Also I could use it for my smoker, hickory makes excellent wood for smoking meat!ย Then a light bulb went off in my head and I had a brainstorm.
I had been Turning Spindle
Blanks into “Fishing Bats” & “Billy Clubs”
I was on a mission turning 3 to 6 inch branches into these bats along with vases, candle stick holders, tool handles and cups from what you could call spindle blanks which were for the most part branches.
Actually,ย I was currently making “fish bats” from 3 to 6 inch branches. I wanted to try and sell them to a couple of the local ‘bait and tackle’ shops in my area and thought I would put a few in my online store. So I had been working with my roughing gouge for the past week making long round blanks, which you could call spindle blanks for woodturning. I wasn’t sure what to call them, I guess they are a type of spindle blank. I just turn a piece until I get all the bark, worm holes and other defects out of the blank. Then I dry them …. drying long spindle blanks. This is when I decided to build a drying cage for spindle blanks.
How To Cut Hickory Spindle Blanks
I’ll see if I can post a picture of the end of one of these hickory tree logs. Basically it is hollow but there can be anywhere from 4 to 6 inches or more of good wood around the outside of the tree. This consists of the sapwood and heartwood in almost equal amounts.

So…. if you were able to harvest the first 6 to 8″ of the outside of the tree you would have 2 colors, the light sapwood and the dark heartwood. Could make some interesting projects. However in this tree there really wasn’t enough to get a decent bowl blank out of for woodturning.
Cut Sections With The Grain Out of The 24″ Log
Hickory is very hard. If you try to turn it dry its like turning concrete. These trees were very wet getting ready for spring growth so they were filled with water and nutrients.
I thought why not take my 24″ log I just cut and slice it down the length into sections that I could make some wide spindle blanks? I’ve never run across anyone discussing or showing how you can dissect a tree like this for woodturning blanks. You could cut a 6″ x 6″ x 24″ spindle blank if you wanted to turn a vase. I cut a couple 4″x 4″x 24″ slices for my “billy clubs” and “fish bats” and they worked perfectly.

Since they were kind of square and had some rotted material on one side I took them to the band saw and knocked off the edges with a jig I made and cut the rotted material off. I also knocked off the corners of the long hickory spindle blank. Turning a square into a octagon shaped piece really made it easy to turn. Hickory is dense and even when wet it was pretty hard.
Since Hickory has a very light colored, almost white, sapwood, and the heartwood is dark brown there were some interesting pieces. I actually turned a couple of blanks for some new tools I wanted with big….long handles. I was going to use oak but now I think I will do a couple with these hickory spindle blanks.
Can Woodturners Use
Rotted Hollow Trees?
I made this post because I wanted to share a new source of wood for woodturning that I discovered. I can’t tell you how many times I walked away from trees that I thought were too rotted and would not yield any wood for wood turning.
I could probably get 2000 or more pen blanks with nice color and grain from these rotted trees…..and that doesn’t mean the blanks would be rotted. As I said, I normally would have cut up the rotted stuff and used it for fire wood.
So next time you run across a tree with a rotted center start to think how you might be able to harvest wood for projects that would go with the the grain instead of across the grain. You could make rolling pins, bowling balls, vases, cups and more cups, bats, light sabers, billy clubs, tire thumpers and fish bats ….you get the idea.
Now I look at rotted trees with a new perspective. It is actually easier to harvest on of these logs because you can cut 24″, maybe 36″ or more off of the dead tree. Then split that piece in half with the grain, maybe split those in half again with the grain and load them easily in your truck or car ….get them home and further process them on your bandsaw or finsih with the chainsaw.
Take What You Can Get
I do not do a lot of spindle turning or end grain turning.
I like to turn wood bowls.
That said, if you are like me you probably have ignored the tree trunk with a big hole going down the center. I hope now if you’ve read this you might look at that rotted tree trunk laying there as a gift ๐ There is so much you can pull out of the first 4 to 6 inches of the outside of a tree that is really is worth your effort to harvest some of that and dry it.
Collecting Wood for Woodturning ….
How to Use and Turn a Hollow Log
Keep in mind, you might find a tree that has at least 12″ of good material around the outside but because of the way it is laying or looks you think the wood isn’t worth harvesting for your woodturning needs. You are wrong, I have 2 or 3 oak trees that are at least 36 inches in diameter and as they lay on the ground rotted and hollowed out in the center there is more than 12″ of solid wood that can be cut for either spindle blanks or bowl blanks that can be used for your woodturning addiction.

And ….. often times the lower part of the tree has a good amount of disfigurement, that is burls, crotches and other deviations that give those turning blanks character that you won’t find anywhere else.
I hope you have at least realized that there is another way to look at trees that can be used for our woodturing habit. A rotten tree may be a liability to a homeowner, it just might be a dead tree in a forest but to you, a wood turner, you can slice and dice your way to harvesting some awesome woodturning blanks ๐




I see lots of questions on whether cottonwood or poplar can be turned. The standard answer for any wood is yes, it can be turned, how well it turns is a different story!




Short answer…..you betcha. Turning it green makes for easy shaping. The bark sticks very good if you want to go for live edge. Once the outside and inside is dry, sanding is easy and finishing is a breeze.


The slab had been sitting outside for a year so it was getting dry. The bowls I made from that piece where further dried in the microwave …..60 second blasts, maybe 4 or 5 times a day.
This picture was from one of the small cherry bowl blanks. It was a 12″ blank I cut on my bandsaw and about 4 inches thick. One thing you don’t want to do when turning these small and thin platters/bowls is to use a recess to mount your cut. That will eliminate the amount of wood that can be gouged out of the bowl. You should use a tenon, to turn the bowl and obviously cut the tenon off at the end of the project.
There are a lot of good posts on where and how people find different sources of wood. How they collect it and how they process it.
Here’s a source I thought you might be interested in. Portable bandsaw mills are located around the country. You just have to find them. Search for sawmill, portable sawmill or contact any of the manufacturers and ask them if they have any of their mills in your area.
These ‘slabs’ as bowl blanks offer 2 types of bowls. You can turn live edge bowls or flip it around and you can cut some nice platters or bowls.
Take this one step further. One of my son’s purchased a bandsaw mill. It is a manual mill, hard work to load the load and then turn it while on the cutting rails. But….I can now cut that first piece any size I want!
The picture shows the Cherry “slab” that I cut into 13 to 14″ pieces. The slab sat outside for about a year and was 15% to 20% moisture level. I should have immediately sealed the ends of those pieces but I didn’t. I just don’t have the energy or strenght to do too much anymore …..very depressing but that’s my life. I eventually did seal the ends to keep them from checking and cracking. I think I had about 10 bowl blanks.
If you try to turn live edge bowls and it almost never fails …..a piece of the bark will rip off and leave a space on the edge. You can sand and shape that edge or you can grab some of the bark and use some CA to glue the bark back on the edge of the bowl. Usually you need to use one of the 2″ sanding disks to shape and blend it into the existing bark …..but a little practice will make it look like it was never missing ๐







You’ll want to check out Tree Services, most local governments…cities, townships etc have a local dump site for free wood and chips, contractors often have land cleared for new construction, I’ve seen so much cut up and left on the side of the road this year.
As mentioned before, check Facebook Marketplace and Craigslist, type in “free wood” or “firewood” “dead tree” “free tree”
