Collecting Wood for Woodturning ….How to Use and Turn a Hollow Log

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 🙂

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 🙂

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 🙂

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!  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,  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 🙂 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.

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 🙂

Drying Long Round Spindle Turning Blanks for Woodturning

How to Dry A Long Round Spindle
Turning Blank for Woodturning

I have some ideas for long round turning blanks, spindle blanks that can apply to a variety of woodturning projects. I’m basically taking a straight branch about 3 to 4 inches wide and turning off the bark and some or all of the sap wood from the piece leaving me a round blank at about 3″ plus wide ….it could be 12″ long or 30+ inches long. I will also take bigger branches and end up with a long round turning blank that is at least 5 inches plus wide.

What Are Long Round
Spindle Blanks Used For?

I can use these blanks for:

tool handles
bats
billy clubs
fish bats
rolling pins
noodle cutters
spaghetti cutters
handles
vases
cups

You get the idea, a long round rod shaped piece of wood. I turn the blanks and dry them. I store the blanks and when I’m ready for a project I select the dried blank and turn the project. Cracking and checking can be a problem depending on the wood species.

Most Long Round Blanks Crack

My problem has been most of the wood I have turned has been very wet. I tried turning and setting on a shelf only to have them crack, at least one good crack. That’s OK, I just fill with epoxy and coffee grounds or just epoxy and color after it has finished drying and re-turn the piece.

I’d rather not have to go through that process for each bat type blank know as a type of spindle blank. So the problem I have is how do I dry the piece and not have it crack. I realize each piece is normally a branch and has the pith through the middle so I need to do a slow, very slow dry. But I’ve even experienced the cracking in non-pith pieces.

How To Build A Drying Cage

I had an idea on how to dry these long round woodturning blanks.

Why not just dry them in shavings and sawdust like woodturning bowl blanks? So I laid a few of the long round turning blanks on the floor in a pile of shavings. Left them there for a week, I kept tripping over them. They were in the way of my workspace but when I uncovered them they were without cracks!

The Horizontal Long Round
Blank Drying Cage

Since I didn’t have any paper bags big enough to hold the long round spindle turning blanks I thought I would have to build something to hold the blanks and shavings but would also let air flow through so the wood blanks would dry. I thought of taking a large piece of pvc pipe and drill a bunch of small holes and fill it with shavings but that would only hold one maybe two blanks and I’d have to drill a million or so holes ….not a good idea.

The I thought, what if I took some wire window screen and built a long horizontal cage? Simple enough, wrap the screen around a circular piece on the bottom and one on the top with a hole in it. You can make it any size. Make smaller cages for small long single round spindle blanks, make bigger cages 12″ or 16″ wide or more for multiple long round blanks.

Staple the screen to the circular bottom piece and top piece. Add 2 long horizontal stretchers to attach the screen to and hold it up. Place your blanks in the cage and fill it with shavings and sawdust.  Place your vertical drying cage in an area to dry …..done deal!

It’s not rocket science 🙂 I built one with an 8″ diameter base. I wish I would have made it 12″ but I think I will make a handful of these drying cages because I’m sure this will work. I did a quick video in case my words aren’t making sense.

I loaded up 3 fairly large long round spindle blanks. First I weighed each blank. Then loaded into the cage and filled with shavings and sawdust. The heat is still on in the shop and I placed the cage as high as I could ……I will re-weigh the blanks after 2 or 3 weeks and see how it works.

Should have Sealed The Ends of The Woodturning Blanks

As I think about it now …..I should have sealed the ends of each blank with wax, paint or anchor seal. I can’t believe I spaced off and didn’t do that ….maybe I will dump the cage and seal the ends of each long round woodturning spindle blank ….they’ve only been in for a couple of days!

Drying Results

I will either edit this post, do another article and/or post in the Wood Turning Basics facebook group the results of my drying cage …stay tuned!
