Placing as design or pattern in a vessel

Placing as design or pattern in a vessel
I get a lot of questions during my presentations and woodworking talks and one that pops up almost every time is ‘how did you do that’ while pointing at a design inside a bowl  or vase. How do you take some design that is flat and make round? Good question!
Using the tumbling block design below I will try to go through some of the steps and methods of doing this without going to deep into the ring construction method used to make the rest of the vase.
 
Above you see the cutting board everyone likes, a basic tumbling block, 3D pattern that is fun to do. Now let’s think about placing it into a vessel.
See below that we have already completed the difficult process of getting good clean diamonds whose 3 parts or diamonds form a single tumbling block.
We then can use these same angles to make diamonds for the top and bottom and longer pieces for the sides. Essentially we are surrounding the design with the same material as our vase. Be mindful during construction to keep the patterns uniform and be sure and make a couple extra as some are bound to be less tight and appealing as others.
Here we are laying out and preparing for the glue up. Remember as you make these single designs you are making one of eight (depending on what you use for a degree and design look, meaning you could form many or more designs in a single highlight ring depending on the look you are after determining the degree of your cut) which means your are determining your vase diameter by the length of the design. Best to start with a vase diameter, determine its circumference and divide by 8 giving you a ball park for the distance from left to right of each design piece.
Here you see it with its rings on the right that will form the sides of the vessel under and over the design ring or highlight ring (I use these interchangeably as the designs are the highlight and they form a ring (one of several) within the vase).
Prepare for the glue up by getting everything in place and each design uniform. Checking for tight joinery and getting the rubber bands out. I use rubber bands for this type of glue up. 6 or 7 thicker ones are more than enough to get you great results. If not the problem is your cutting and accuracy of miter not more clamps.
This next step requires cutting jigs. If you have been to one of my presentations you know how I feel about jigs, all kinds of Jigs. Here I will be laying out MDF for a precise cut making the top and bottom uniform and accurate according to the design in the middle. This cut will then be the basis of the right and left hand cuts so this one is worth getting right.
I love double stick flooring tape which you can get at any Home Depo / Lowes.
It holds everything in place nicely. Remember you are lining up the center design here not the edges of the glued up piece. You want the designs in the center to line up more than just cutting off the bottom and top. The jig will allow you to move the pieces and hold them in place in a way to insure the uniform look of the design in the center of the highlight ring.
Above I have marked with pencil to insure that my designs are centered.
Here are my jigs all loaded up and ready to rip on the table saw. Use a good sharp blade so you can join right away or keep your jigs in place and run it through the planer and thickness sander if you have one. Mine usually are joined with table say cuts only. A good blade makes all the difference. Mark the outside of your jigs with the lines of the designs from the inside so you know you are taking as much from the bottom of the ring design as the top.
Here they are all 8 just off the jigs with their bottoms and tops perfectly aligned. This perfect alignment is then the basis of the miter cuts to join them.
Again, a cutting jig is essential here to getting a good cut and safety. Also marking to center the design is the key. You can see my mark on the jig below the clamp. It is set for the center of the design not the edges of the piece. The center of the design is the standard to set your cut against. Before the saw is turned on your fingers should be far removed from the entire saw area and the piece should be locked down by clamping with a certainty it will not move or vibrate during the blade pass.
Here we see the cut off with design center lined up with the pencil mark. Keep these cut off’s !!! I have made funky and wonderful small projects (Christmas ornaments especially) with these. They are exact, witch means if you join them correctly they will fit together just as your ring will, making a clever little, whatever.
Here are the segments ready to make into a ring. At this point you can choose to further highlight or not. For example with these Ash rings I will make windows around each design by inserting another wood in between each design segment. On the Black Locust I will not.
This will begin to move rather quickly so I will try to let the pictures speak more.
Check for a good tight fit with no gaps before gluing. If you have less than perfect joints use the half ring method, forming and gluing up half circles and then sanding the two remaining joints to perfect fits. Much easier to work with two joints than 8.
Here the highlight rings have been glued up and are ready to go. Notice I inserted a piece of black Locust in between each of the ash rings to make the left and right sides of the windows
Now, finally after weeks we have something to put on the lathe. Centered we begin to add rings as we go. The top and bottom of course will be black locust in order to close our windows for each design highlight. Rings of Brazilian walnut help to further highlight.
The black locust vase will be plainer and less decorative by design.
I use a lot of weight instead of clamping. Make sure the weight is evenly distributed or it will show in wider than necessary glue lines. Check out my post on PVC for more info on that.
Here is the ash vase with the black locust windows and Brazilian highlights. All in all I think it came out good. Not great but a solid good.
Interior shot.
Here is the black locust with no extra highlights. My wife likes this one best. Sometimes less is defiantly more. For me I like the more complex designs and therefore the ash with highlights. Sometimes less is defiantly less, right?
Anyway, whatever your preference or design choice these steps can help you get something whose design is flat (cutting board) and design it into something round.
Keep turning and be safe

triangles , triangles and more triangles

Here are a couple of vessels I just finished, fresh off the lathe.

Both have The Oats design of from
To the left a maple with walnut vase with a teak hat
On the right a segmented walnut vase with a blood wood top ring.
Both were lots of fun.
Hoping to have a web site up soon so stay posted.
Steve
P.S. I will be doing a presentation at the Sandown NH public library Tuesday March 27th at 6PM. Would love to see you there.

Fruit of the Triangle

Well I promised you

some pics of the fruit of my triangle design so here they are
the Glue ups were very difficult because they were not multi- generational but one large glue everywhere mess. That being said still they came out nice. One vessel using a stay construction and 2 cutting boards. Let me know what you think. Triangles of Teak, walnut and cherry with some birch triangles on the edges.


Triangles

I have been playing with triangles lately.
The cut out show the design I am headed toward.
Lots of rubber bands and 3 color triangles.
this is a single generation glue up , so needless to say lots of clamps and special glue up jigs are a must , but they are easy to come by and the jigs easy to make.

After playing with them for a while I have decided on two forms. A cutting board and a vase.
the upper 6 will be developed into a vase using stay construction and the lower as seen below.

 

These are in glue up now so in a couple of weeks they should be close to finished and on the blog.

If you are free on Feb 28 or March 7th would love to meet you.

Funky gyroscopic segmented piece. Way outside the box


Here is some fruit from the multi generational tree.
This one was an experiment with half step 15 degree fallowed by a peak to troft cut.
all in all , 3 generations and very simple glue ups.
then we use a stay construction to make it into a Vase.
Walnut and birch with mahogany balance rings.

Another cutting board pattern



I had so much fun with this cutting board thing that I decided to try another project. This time I used 3 types of wood and combined them in pairs. One vessel (weed pot design, 12 inch height , 7 inch diameter) of mahogany and poplar, one of poplar and birch and the third of birch and mahogany. I used ebony bases and tops. We will use pic’s to show the process since we have been here before.

Here I have taken the bottom and inserted a plug in order to sign and date. The ebony will not show any detail so this is important. It is always important that you sign and date your work. Your grandchildren will thank you for it.

Here is the result


Enjoy

Cutting board to a bowl or vase technique

Making a bowl or vase from a cutting board technique

Here is a fun project that is similar in many ways to the cookie method only easier and simpler. This particular method has a very high ‘ou aha’ factor with not any real high degree of difficulty and really looks great. Also it has may variations and twists and turns to keep your work original and dynamic.

It difers from the cookie method in that it is simpler. You do not need to angle your rings to make one bowl from one cookie, rather you can make lots of material and create and harvest as many rings as you wish to get the forms and shapes you want.

The down side of this method is end grain. Yes, unfortunately you will be turning end grain with this process, but there are some woods that lend themselves to this better than others so pick your material with that in mind.

The making of the cutting boards is basic so in a picture here is the process.

Cut lots of material same width and length

Glue it up and make a cutting board, or many of them. They will become your material.

Mark them up with the sizes of your rings making sure to leave enough room for the blade width.

Mount your rings to a backing board of MDF attached to a face plate. The backing board will help reduce the blow out when your tool goes through the back side of the material.

to insure accuracy Make sure your potential wall thickness is adequate.

Get funky with the alignment of the stacking and glue it up in two’s and then on the lathe


Simple, easy to work with and no math, my kind of project.
Enjoy, Steve

If you give a turner a cookie…..




Making a bowl from a cookie

If you give a moose or a mouse a cookie or a muffin he may just want to turn it into a bowl. It has been too long since my last posting but I promise to make this one worth your while. If you like the salad bowls below and have only scrap wood around you, this is the perfect project. It takes a while but it is tons of fun and will push your skills. This can be done with a single board (which I recommend for practice) but segmentation allows you to avoid end grain turning and gives you and endless number of combinations in color pattern and style (which is where most of the creative fun is).

So if you like these Cheery and Walnut bowls, lets get started.

Things you will need:

Screw clamps (can be ordered at Grangers, pack of 10 for cheep)

Different colored material in uniform width and depth (length is not important but that you have enough is).

A very thick pasty glue, not a thinner extended set up time glue.

Varying sizes of hole saws (not absolutely necessary but speeds things up).

Must have a face mask, full shield, absolutely.

Large jaw chuck 4 to 6 inch

Face plates for each cookie

OK, so let’s get started

The shape is somewhat pre-determined on this project. You are making salad bowls and the angle of the bowl height is predetermined as you will see later. What you can determine is the pattern and look of possible bowls. You do this by deciding what pattern to make the cookies. The objective is to make cookies out of segmented pieces of wood that then will be used in combination to make bowls. So we begin with making cookies like those below.

Remember you have 360 degrees to work with so count with care. See in the pic my cut list on the vertical board. For example one cookie may consist of 9 slices of 10 degree pie and 9 slices of 30 degree pie as the one closest to you in the pic above. The 10 degree pieces are made up of 2 five degree cuts to get the 10 degrees and likewise 2 fifteen degree cuts to get the 30 degrees. So 9X10 is 90 plus 9X30 is 270 gives you the 360 needed to make the circle. I have used many combinations of degrees to get my 360 including non uniform random patterns (applying the fibinachy sequence here can be fun for all you math heads). The cookie on the far right is of scrap. Always make an extra one of scrap to take to the next step first. Better to practice on it first. If it makes it all the way through the process you can give it to your mother in law, she will love you for it.

Making a 360 perfect is always problematic if not completely unattainable. All I can say is make your miter cuts as accurate as possible weather you use chop saw or table saw. Keep this in mind, the tighter and cleaner your joins the less wood will be flying around the room when you turn (full face shield is a must). Also remember that excessive clamping will not make up for bad joinery, just because you squeeze does not mean they are tight. One way to insure this is to do the half ring program. Make your cookies a half ring at a time so that the slop (the less than 180 or the more than 180) end up in the middle with a nail or round dowel rod to pivot on. Then sand or cut off to a proper 180 middle, then glue up the half’s into a whole. I use this a lot when the pattern will allow. As you can see from the above some of these patterns would not because the number of degrees did not allow for 180 (in other words, there is no middle point that cuts the cookie in half). Also when you trim the middle you lose conformity with the other cookies you might not trim in the exact same way. This will bite you in the ass later when you swap out some cookie rings for other cookies rings but more on that later. For now just know that the more they are similar with each segment uniform not only to the other segments in the cookie but each cookie similar to the other cookies, the more they will look like you actually knew what you were doing when you made them (which is nice but not required, remember you can always go the random route which hides a multitude of sin).

The next step is mounting the cookies to the lathe. Actually simple and straight forward first we mount a block of MDF to a face plate (honestly the MDF never leaves my face plates. I glue more on as I use it and turn it off) and then mount the face plate to the cookie. This allows us to get it on the lathe to clean up the other side of the cookie and mount the bowl bottom which will double as the mounting block for our chuck and triple as the center of the hub of the interior of the bowl and provide a forth benefit of keeping the bowl bottom from shifting around in time by being glued to 5 to 6 inches of stable material.

Above are the cookies being readied with the walnut bottoms on hand prepared with a hole saw.We mount these face plates to prepare the other side on the lathe to except the walnut bottoms. It is vital that the entire surface be scraped and sanded flat. Use a straight edge to help. I use the sanding block made of Formica counter top. This is your only chance to make the bottoms of the rings you will harvest later flat. If they are not flat they will not sit properly on one another later in the process.

Now we are ready to mount the bottom by first cutting a uniform hole to accept our tendon which we will make in a portion of the walnut bottom. The uniform hole can be done with a hole saw as shown.

Now we are ready to make our walnut bottoms with its tendon

As the pic says, I hope you are wearing eye protection. Using a hole saw I start the process and make a tendon that fits the hole in the cookie precisely. Remember that any slop in this fit will be very evident and visible in the bottom of the bowl.

Now we are ready to mount to the cookie and cut away the MDF and face plate

Removing the face plate we can then prepare what will be the interior of the bowl by scraping and sanding perfectly flat and smooth the face plate side of the cookie. Again much care needs to be taken to make sure it is flat or it will show up when you try to put another ring on top of it.

The above is the goal, to have the bottom used as a mounting block for the chuck so that we can begin harvesting rings by parting them from the interior of the bowl.

Here we have a cookie, mounted in the chuck, the tendon of the bottom seen in the center of the cookie. Looks like a nice fit. Now the parting tool. Lots of parting with this project. Here is where the face shield is an absolute. You can not know if every joint is tight, so wear it. The idea here is to harvest rings that will fit on top of each other because they are cut on the bias or angle. Set a 45 degree angle on the tool rest to make sure your cut is consistent. Less than 45 and you will get into trouble with wall thickness. Allow yourself at least half an inch or more in the distance between rings, which will be your wall thickness before you turn. You will need all the room you can get to fudge the patterns to make them look good and consistent in the final product so thickness now will pay off later, but not to thick or you will be making a plate not a bowl, right?

A quick word about parting. Wear your face shield. I use at lease two parting tools. One used for cutting the other in water cooling. This process generates a lot of heat. Don’t let your tools over heat, also keep them sharp. The sharper your tools are the less you will have a problem with heat. Watch constantly for bad joints and pieces that want to spin off (bad joints can be treated with super glue on the spot). Most of the time bad joins will reveal themselves more through the sound of the turning than sight. Turn slow, 500 to 900 tops. At this point you also have another alternative for cutting and harvesting rings, namely the band saw. You can if you choose put your band saw bed at a 45 degree angle and cut your rings that way instead of on the lathe. Of course you will have the entry scar from where you entered the particular ring but with gluing that can be dealt with. It is a much safer, easier way to handle it although you will have the glue line from entry. Some have dealt with the glue line by cutting the rings off the half circle or half cookie which is another way of doing it, however I find it difficult to glue together two half’s of a ring that has a 45 degree surface and it makes making the surfaces perfectly smooth and flat problematic. I have used both ways and both have worked, still there are many ways to accomplish the same result; this is just the one that I currently feel the most comfortable with.

So here is what we are looking for, rings at a 45 degree so that the bottoms will fit on the top of the previous ring.

Off the lathe they should look like this

Stacked properly they should begin to take your salad bowl shape

Now this is where the fun really begins.

What would happen if……

… we swapped rings?

Played with each combination?

What might happen?

Well for one thing you would have a blast, but remember you can only swap if you have been very attentive to each angle being 45 degrees and each cookie the same diameter and each ring in that cookie the same interior and exterior diameter and thickness both on the bottom and top. It is a lot to keep track of but here is where is pays off, complex patterns that are simple to form. And what is the down side? What if you mess up a bowl different from the rest? Still you can rotate the patterns of the same cookie and they will fit to get a great look or try a random look. Worst case you can always give it to your mother in law, right?

The turning from here is pretty basic. After just make a jig to flip and finish the bottoms away from the chuck mount look and more into the bowl bottom look, sign and date always even if it is a sharpie. Your kids will appreciate it.

The pics below are how my 6 turned out. Notice that with close inspection the patterns are not perfect but merely close. The practice bowl never made it to finishing. It is in more pieces than I care to mention scattered across my shop floor the victim of bad joinery.

Having fun on

Oh, by the way I found this glass inside this vase during the turn. The scrapes and waste of this style are almost more fun to play with than the original concept.
