Default Twisted tutorial/photo journal

Hi everyone,I photographed my way through a twisted pen design.For those of you that want to give it a go I hope you can find this usefull.

I started with a 1 1/2 x 1 1/2 x 9 spindle blank.I thought it was Bocote.1.jpg

Turn to a cylinder and then layout 4 sets of points r1/4" with a compass.
I did one end,useing the tool rest as a guide I drew a line across the length and transferred the points on the opposite end.

This part can be distegarded if you have the right jaws.I initally turned the blank to a cylynder with tenons on both ends.I did this because my #2 jaws were too big and I didn't want to over extend my pin jaws.When I went to set the outer points the wood started to split so I had to make reinforcement collars and just have to deal with the jaws the way they are.2.jpg

After trueing the collars up I parted the blank where I wanted the lengths of the body and cap.3.jpg

Remount the blanks for drilling 3/8" x 2" for the body.27/64" x 2" for the cap.4.jpg

Once both cylinders are drilled I set them aside.5.jpg

I made a double sided tenon a little over 4".Using a dial caliper make each side just a little big and then sand it down so that it fits very snug.If it is a little long just trim the tenon a little bit.6.jpg

After both sides are done reassemble the cylinder with the tenon inside.7.jpg

Trasnfer the lines to the end and number them 1-4.Offset the numbers on the opposite end.8.jpg

Press all the point sets in.You may need to predrill them a little bit on really hard wood.Mount the cylinder between one set of points and lets get started.9.jpg

I turned at full speed, 3300rpm.Looks kinda weird with all that airwood spinning around.10.jpg

The first cut I turned away the ghost.11.jpg

I got out a measuring stick and marked it.I will use this mark through all the point sets.12.jpg

Remount the cylinder to the 2nd point set.13.jpg

This is what it looks like after the second cut.14.jpg

Remount it to the 3rd point set.15.jpg

This is what it looks like after the third cut.16.jpg

Remount to the 4tg point set.17.jpg

This is what it looks like after the 4th cut.18.jpg

Remove the cylinder from the lathe,slide the halves apart and check the wall thickness.19.jpg

I wanted the walls to be thinner so I remounted the cylinder and ran through the point sets a second and third time.20.jpg

Once satisfied about size I remounted the blank on true centers and sand out any tool marks with 220g.Part off the ends.21.jpg

Time to clean up the ends.Remove either the cap or body and remount it into the chuck by the tenon and now clean up the end.22.jpg

Remove the tenon and do the other half same as the first.Remove from the tenon and set aside.23.jpg

Remound the tenon by the small end and drill out the large end with a 7/64" bit as far as it will go.24.jpg25.jpg

Remove the tenon and layout all the parts including the refill.Place the refill in the body.With the tenon placed next to the body and refill mark where the shoulder of the refill will be on the tenon.26.jpg

As you can see the tenon is too long for me to drill so I will mark it again where I will part the excess off.27.jpg

Remount the tenon by the large end.After parting off the excess I drilled to the depth marked on the 15/64" bit.28.jpg

Remove the tenon and check the fit of the refill.It's a wee bit long29.jpg

Remount the tenon by the small side.Shape,trim and sand what is now the front section.Testing the fit as you go.30.jpg

Dale,
Nice job on the write up and the pics!
Thanks

A while back, I turned a 4 sided twisted cherry cup.
These are good skill building projects!

Ran out of editing time.

Once it's where I like it I remove it from the lathe.31.jpg

Assemble the section to the body,press on the tip of the refill to test for any front to back movement.32.jpg

If there is remount the section in the chuch leaving the shoulder exposed.Trim a little off at a time and retest the fit.33.jpg

Assemble all the parts.If there is any finessing of the fit that needs to be done,it can be done by either sanding the inside of the cap and/or body if it's too tight.If it's too loose you can apply CA with a Qtip to the inside of the cap and/or body.

Now I can finish sanding the outside of the pen.It has to be done fully assembled or I will not be able to blen the seam together.I use 220,320,and 400gsand paper.34.jpg35.jpg

Fininshing can be done a number of ways.I've done a buff and wax method and I've also done a shellac and wax finish.This time I will do a laquer finish,I will post it in SOYP whe I have it completed.

I hope this tutorial is of use to you or at least interesting.

Best wishes, Dale

Am I correct in deducing that to replace the refill you remove the tenon piece ?
