Scrap Wood Project Yarn Bowl Discussion and Plans

Hi Everyone,

Well, its gotten much cooler here and rainy too. What kind of weather is this? Yes, wood turning weather!!

Ok, our next project is a scrap wood project and here is the discussion behind this:

Discussion

I had some 12"x1" pine boards left over from a recent project along with a piece of 12"x2"western red cedar that I had been eyeing for a couple of days and wondering what I could do with all of it. I suddenly got the idea to laminate them all together and make a yarn bowl. Linda, my buddy who tests a lot of my kitchen ware, is also an amazing knitter and I got the idea she might like to try out a yarn bowl for me. I emailed her and she said yes but to make it deep with a wide bottom so it cant easily tip over. So this is what were going begin making today.

Plans

I am going to make the bowl out of yellow pine with a red cedar bottom. If you google the words yarn bowl youll see what they look like-typically a large, flat bottomed bowl with either several large holes drilled into the side or a hole-slot combination. The hole-slot thing allows the knitter to pass the yarn through the hole without having to break the yarn and it keeps the yarn in the bowl while its being knitted.

I used 8 - 12"x1" pine boards and cut them into 11" circles and I did the same thing with the red cedar. Im going to coat them liberally with wood glue, clamp them, and let the whole thing dry overnight.

Lets take a look at some photos:

Here is the stack ready for gluing. The whole thing is about 7"high and 11" wide and even though it looks huge in the photo, its not very heavy, which is important for my lathe as I dont want to exceed the operational limits by turning too heavy a block. You can also see a line on the side-Ive drawn that line on the edges of the boards to keep the end grain patterns lined up:


Im going to use carpenters glue and an old pain brush to spread the glue around. Ive also laid down a plastic trash bag to help keep some of the glue off of my work bench:


I cleaned all the wood dust off of the surfaces and applied a very thick bead of glue:


Next I spread the glue evenly across the surface, making sure that the edges have a thick, even layer:


And I did that repeatedly. Here is what the whole thing looks like at the moment:


Now, for difficult part: clamping the whole thing together. Laminated turning blocks need to be really solid and this means having enough clamps to produce even, hair-line joints in the block and ultimate in the bowl itself.  I used as many clamps as I can fit around the edge of the block, which in this case was 8 clamps:


Screwing down the clamps always makes the wood shift around a little so its helpful to have a mallet, in the photo you can see I use a plastic mallet, to gently tap it in place:


And then I clamped the hell out of it. Screw it down as tightly as possible. You should see glue oozing out of the sides of the block:


And Im going to let it sit for 24 hours. Well come back to this tomorrow.

Hollys Walnut Bowl Discussion and Plans

Hi Everyone,

Today were going to begin a bowl out of black walnut and this bowl is going to be a gift to a very special friend of mine and heres the story about my friend Holly and this particular piece of wood:

I have a wonderful friend named Holly who lives out on a farm with her family and a whole bunch of very friendly chickens in Afton, Minnesota. Several years ago during a strong wind and rain storm a large black walnut tree that was growing on her property, roots gave way and the tree came down. Knowing that I turn wood, Holly told me about the tree and offered to give me the trunk from the tree and so my youngest son and I went out to Afton to get it. As it came down in a rainstorm it was full of water and so it was very, very heavy. I cut the trunk into sections and then split one of the sections in half and made bowl blanks out of them. I tried turning a bowl from one of the blanks but it was just too wet for turning and so I treated the cut ends with Anchorseal and stacked them away.

Fast forward almost 2 years-the blanks are much, much lighter in weight, signifying that the wood is much dryer and ready to turn. I took a portion of one of the blanks and made a small flower vase several weeks ago (and you can see this on the blog). The wood was dry and the vase came out absolutely beautifully. Time to make Hollys bowl and take it to her and the chickens.

Discussion and Plans

I am going to do this project in slow, easy stages as I think this is a good way to illustrate this project. So my first posting today will be about getting the blank ready to be mounted on the lathe and Im also going to show the blank mounted on the lathe at the end of this posting. Subsequent posts will show how the blank is shaped and hollowed out and lastly how it will be finished.

Here we go:

Here is a photo of the bowl blank. Its a big thing, about 6 /12 inches at its deepest and about 9 inches wide and 11 inches long. In order to turn this on my lathe, its going to have to be cut down considerably. So the first thing I did was to find the center of the flat side of the blank. This will eventually be the top of the bowl and since the blank is deep and thick, I can screw down a large faceplate and use long heavy wood screws to do that with:


This photo shows the blank with the center marked out:


In this photo is the blank, the faceplate Im going to use, which is 6 inches in diameter, a center finder so I can get the faceplate reasonably centered on the blank, and some long wood screws:


 In this photo you can see how large and square this blank is. As this blank is too large to turn on my lathe, it will have to be cut down. Im going to cut off the corners and trim it some and I  can do this one of two ways- I can eye-ball it  or I can use a small plywood template (see below) and use that while Im sawing it with the bandsaw. You can also hand saw this with a carpenters handsaw:



Heres the blank after Ive sawed off the corners and some of the excess wood. Note the circle in the center. Thats the approximate size of the finished bowl:


The waste wood looks like chocolate pie!


This is a photo of the faceplate and the center finder. Im terrible at estimating where the faceplate should be placed. On this piece of wood its not real critical if I dont get the faceplate absolutely centered but on rounded blanks of wood it is, so I thought Id illustrate this. These two pieces screw together and in the center is a drill bit. I screw everything together and then I put the drill bit in my hand drill and drill the whole assembly into the center point that I found before I began cutting the blank:


Heres the whole thing screwed down. Now I can drill holes for the screws and screw them in:


I used my hand drill for all of this. Much, much easier to do! Now the faceplate is properly centered and screwed on securely:


Now that the faceplate is screwed on, Ive mounted the faceplate-wood blank on to the lathe and spun it by hand and it spins freely so weve gotten the blank on there correctly.  Here is a photo of the tailstock and the tool rest in place. Its ready to turn:


Now before I begin turning this there is one last thing to do and that is to cut away a small section of tree bark were the tailstock is inserted. This will let me screw the tailstock firmly into solid wood instead of the bark, which is spongy and crumbly. Never screw anything into bark:


And Im going to stop here. Tomorrow Ill begin roughing out the bowl with my roughing gouge. Tomorrow is going to be a really dirty, messy day but well wind up with the exterior of the bowl cut and shaped.


While I was working, UPS delivered a wood blank from Wood Turning Blanks 4U in Braedon, Florida. This is a wonderful source of turning wood and Steve and Diane, the couple who operate this, do a superb job of processing wood from trees that have fallen in storms or had to be removed for some reason. This keeps these marvelous sources of turning wood from either being ground up for mulch or dumped in a field somewhere. You can check our their site at: http://www.woodturningblanks4u.com/. I wish they would move to Minnesota.

Anyway, this blank is going to be the basis of another future project that well do together. This is silky oak:

Ok, its cold and were due for more snow this afternoon. Time to go in and talk to the cats. See you tomorrow.
