5 Loop Celtic Knot In Perfect SphereThis journey thru Celtic knots has resulted in an easy and repeatable process that greatly simplifies preparation of the turning stock. In previous descriptions, the project wood had to be milled to exact dimensions: squares for four loops being the easiest, triangles for three loop, pentagons for five loops.

The significant realization was that it’s not the wood that has to be milled. The milled wood was shaped to provide positioning for the cutting angles. Instead, we only need to make plywood polygons that can be attached to the ends of the wood to maintain positions.

To summarize how to make a n-loop Celtic knot:

  1. Prepare appropriate stock for the project. The only requirement is that the two opposite end be parallel and their centers drilled to a shallow depth.
  2. Prepare paper templates with polygons with sides equal to the number of loops desired in the Celtic knot: triangle for three loops; square for four loops; pentagon for five loops and so on.After the previous video with a Celtic knot in a barbecue flipper, several comments included a suggestion to leave a little wood when the angle cut is made to keep the wood spaced correctly. In addition Michael challenged me to make a 3 loop Celtic knot. The project wood must fit inside and be centered on the center of the polygon.
  3. Glue the templates to plywood, rough cut, and sand down to the perimeter line.
  4. Temporarily glue the plywood polygons to the ends of the project wood. Use a small nail thru the plywoods’ center and into the center of the project wood.
  5. Choose a cut angle for the knot.
  6. Prepare the saw with appropriate stops and supports. Do NOT change any stop or support until the project is completed to reduce the opportunity for error.
  7. Set the depth of cut to allow a thin piece of wood to remain connecting the otherwise two pieces of wood. Use scrap wood temporarily glued to the project wood to supplement and reinfore the cut area before making the cut.
  8. Make the cut.
  9. Prepare contrasting spline material to easily slide into the saw kerf.
  10. Glue spline into the saw kerf. Work quickly to insert and position the spline before the glue sets. Do not use CA glue.
  11. Clean up excess spline material and the scrap reinforcements.
  12. Repeat steps 8,10, & 11 for each additional knot loop.
  13. Finish turn the project. Hurrah.

How to make a perfect sphere or ball.

  1. Prepare a faceplate with a cup that fits the rough ball. Find a rubber stopper about twice as large as your threaded(hopefully) live center. Drill to fit the live center.
  2. Measure the diameter of the spindle. Mark that length on the spindle, centering as necessary.
  3. Partially part outside these marks to indicate the top and bottom. Rough turn the ball between centers. Make a pencil line at the equator (largest center) of the ball.
  4. Saw off the small tenons.
  5. Rotate the rough ball 90 degrees and mount to the cup faceplate, holding it with the rubber stopper on the live center. The equator line should now run parallel to the turning axis.
  6. Use a scraper or other gentle tool to carefully remove any wood higher than the equator line but be sure to leave the line.
  7. Mark a new equator line.
  8. Rotate the ball 90 degrees so the new equator line is parallel to the turning axis.
  9. Use a scraper or other gentle tool to carefully remove any wood higher than the equator line but be sure to leave the line.
  10. If satisfied, move on to sanding. Otherwise, repeat steps 7, 8, and 9 until you are.
  11. For each sanding grit repeat the same ball rotations used to turn the ball but don’t mark equator lines. Do the same process by eye. That will be good enough for sanding.

Good turning.

Knotted Back Muscles? Back Pain Relief With Celtic Knot

After the previous video with a Celtic knot in a barbecue flipper, several comments included a suggestion to leave a little wood when the angle cut is made to keep the wood spaced correctly. In addition Michael challenged me to make a three loop Celtic knot.

In this project, I’m accepting his challenge and incorporating these suggestions.

A three loop knot requires three cuts at 120 degrees separation. Instead of milling the wood into a triangle, I made two plywood triangles and glued them to the ends of the timber.

Then it was off to the races.

This same process could be used to make Celtic knots with any number of loops. Just vary the end pieces and perhaps the cut angle.

This little handle is actually a tools to massage your back. You’ll need assistance from someone else to roll it on your back or to massage specific muscles with either end for different pressure.

In this project, I’m making a handle for a barbecue turner. But not just any handle – this one has a Celtic knot.

For the celtic knot, I threw together a sliding cutting jig to ensure accuracy in the cuts that have to be just right.

A Celtic knot is a series of four angled cuts with a new wood slice inserted and glued in.

Meanwhile, I’m trying out a Jacobs chuck with which to hold drill bits while drilling on the lathe.

 

Woodturning An Ornament Or Birdhouse Stand

Ornament Stand

In preparation for this year’s Christmas Ornament Woodturning Challenge, I decided to make my own ornament stand. It could also be used for a birdhouse or any other small hanging.

It is surprisingly easy to make. The base is scrap wood from another project. The brass is 1/16″ diameter brass rod but should be heavier such as 1/8″ diameter to be less bouncy.

This stand is finished with Mylands Friction Polish then buffed.

Woodturning A Wild, Crazy, Wavy Bowl

Cedar Wavy BowlMay also be viewed on YouTube.

After returning from the Utah Woodturning Symposium, I felt I needed to break out, break away from my habitual projects.

So, I found this chunk of cedar and went to work on it. It wasn’t the best piece of wood but I managed to turn a wavy profile.

It turns out to be an unusual double sided bowl. If you’ve seen one like it, I’ll be surprised.

Maybe it works for you, maybe not. But it works for me.

Approximately 11″ x 2″ finished with walnut oil.

Practice Woodturning A Basic Walnut Bowl

I contributed a woodturning experience to a church youth auction to raise money for youth summer activities.

In preparation, I’m turning a bowl similar to what I’ll have the auction winner turn – with some exceptions.

They will turn a softer wood like cedar. This one is hard walnut with some rot veins in it.

So much turning is second nature to me now, I want to review the basic process for turning a small bowl to be ready to coach a newbie again.

Woodturning Twisted Horns Of A Dilemma

Strange Turned Box

I’ve wanted to turn this project every since seeing Michael Hosaluk demonstrate it.

It is basically a turned box but with a twist. The top and bottom are elongated. Then at the band saw, each is sliced, the segment turned about 180 degrees then re glued. In this case, the top and bottom segments were sliced and re glued twice each. This process gave them a bit of an arc.

The inside surface is distressed while the exterior is sanded into a flowing shape. Finally, the box is painted with acrylic paint and a texture applied of acrylic gel.

With no grain alignment, there is no “right” way to position the top with respect to the bottom. Thus, the box can assume many different shapes or characters.

When I first saw one of Mike’s I just had to pick it up, twist it around and try to figure out how he did it. It’s fun.

I turned this napkin holder for my wife for Mother’s Day from walnut.

It consists of a round base and two round sides. The sides have a little wood sliced away so they can stand on the base.

The space between the sides is perfect for dinner napkins.

The walnut is beautiful.

Since spring has arrived, it’s time for picnics and barbecues.

How about some deviled eggs for those occasions?

I used the split turning technique for this project.

  1. Glue two pieces of walnut together with brown craft paper between.
  2. Turn an egg then split it into two halves.
  3. Turn the deviled yolk and glue it to the half egg.
  4. Proudly serve your deviled eggs at the next appropriate occasion.

Enjoy!

Remount & Finish Woodturning Naturally Spalted Aspen Bowl

Bowl in Spalted Aspen

This aspen bowl was turned wet or green several years ago. At that time, I put it away in a paper sack for it to dry. Apparently, it was extra wet or did not dry very quickly, since a large growth of mold or fungus developed on the surface. I brushed off the mold or fungus and left it to continue drying without a paper sack.

After wet turning, I did not expect much from this bowl. Aspen is a fairly plain wood. This being the case, I was in no hurry to finish turn it.

However, I was in for a big surprise. Rather than being a problem, the growth did me a favor by imparting additional color and interest to the bowl thru spalting.

The bowl is eight inches in diameter and three inches in height, finished with walnut oil and buffed to shiny perfection.
