How to Deep Hollowing, Advanced Wood Turning

How to Deep Hollowing, Advanced Wood Turning. I give instructions for more advanced wood turning. I show the steps and tools required for deep hollowing a vase.

[@thefish5861]

I once spent over an hour getting a jammed forstner bit out of an end grain vase. You are definitely right about constant clearing of the bit.

[@BrailsfordWoodworks]

It is a hard lesson to learn for sure! Thanks for watching!

Excellent “Mike” vid! Most explaining thoughts and techniques ever. Thank you

[@BrailsfordWoodworks]

Thank you Stephen!

[@DougMilleratWoodSpunRound]

Great start on a beautiful vase.

[@BrailsfordWoodworks]

Thank you Doug!

Thank you for your time and effort in this video to help others like myself.

[@BrailsfordWoodworks]

My pleasure! Thanks for watching!

[@craigabel3674]

Nice video Mike. I much appreciate your efforts in getting these for us to view.

[@BrailsfordWoodworks]

Thank you Craig! My pleasure!

Am enjoying this. Have not heard of boiling wood before. One of our club members freezes his once turned work with the theory that once the cells are frozen, when they thaw they will no longer retain fluid and will dry. Another uses a kiln made from a non-working stand up freezer, while yet another uses dessicant beads and another puts his in shavings in a lidded plastic trash can. Thank you for sharing your knowledge with us!! Anxiously awaiting the Part 2 of this method!! Hope 2023 is a healthy and happy new year for you and yours!!

[@BrailsfordWoodworks]

What I have been told is boiling (and perhaps freezing would do the same thing) softens the lignin fibers, allowing the bound water to leave more freely, Thanks for watching!

[@scottfonner]

Great project, looking forward to seeing this finished up.

[@jonart9160]

As a rather new woodworker to turning, I like your sharing of knowledge. Looking forward to the boiling thing. I've never heard of this technique before.

[@BrailsfordWoodworks]

Thank you! Keep watching! I want to build up several pieces to boil at the same time. It might be a few weeks.

[@edmodzeleskytrs4535]

Lots of good tips. I think I'm going to learn a lot from you.

[@BrailsfordWoodworks]

Thank you Ed! I am glad I could help!

[@rondagan7811]

Fantastic demonstration

[@BrailsfordWoodworks]

Thank you Ron!

New sub, enjoyed your hollowing video and like to help grow the woodturning community.

[@BrailsfordWoodworks]

Thank you very much! Welcome!

[@brucecraig4954]

A little wax on but makes it much easier as well. 😊

[@BrailsfordWoodworks]

Thanks for watching!

Incredible video MIKE. Thanks for sharing. Very interesting to watch. Hope you had an amazing Christmas. Happy New Year. Keep the content coming. Hope you have an incredible weekend. Much love and RESPECT brother

[@BrailsfordWoodworks]

Thank you Tim!

[@Mauroiltornitore]

Great video, my friend! Thanks for sharing

[@BrailsfordWoodworks]

Thank you Mauro! Happy New Year!

[@thomaslee4202]

Nice Video Mike! I'm wondering about some of the chisels you're using. Specifically the roughing gouge you started with. It looks to be a 2" gouge, but I'm guessing here. Also the skew you used. These two chisels are on my "to buy" list. My Crown chisel set just isn't up to par anymore. And what you're doing is exactly the path I'm on these days. Again, thanks for the great intro into hollowing. Tom

[@BrailsfordWoodworks]

The large gouge in my spindle roughing gouge. My large skew is from Hurricane Wood Turning Tools. If you are looking to upgrade your tools, I recommend Robust Tools Turner''s Edge tools. They are amazing! Thanks for watching!

[@dannyvenier4728]

Great video, got me thinking. What do you think is a reasonable maximum length of a container you would or could hollow without the supporting jig? The idea I'm considering is to hollow a half dozen or so cylinders and attach them to make a wine rack. So maybe a little over 3" inside diameter and about 9" long would carry a normal wine bottle, at least the wide part, with the necks sticking out. If it were a hardwood, like ash, would a tenon in a good oneway chuck support it enough to hollow it without some additional support?

[@BrailsfordWoodworks]

Thank you Danny! I would suggest that 9" is probably doable. I don't think I would go muck longer than that. Good sharp tools are a must.

[@jeanlong4285]

Very interesting, can't wait to see you finish this hollow form. When do you think you'll show part two?

[@BrailsfordWoodworks]

Not quite sure yet. I want to get enough pieces done so I can boil several at the same time. Thanks for watching!

[@charlessienk9189]

Never heard of boiling a piece of please explain the process

[@BrailsfordWoodworks]

There are two types of water in wood, free water and bound water. The free water will leave a piece of wood very quickly. The bound water is within the cells of the wood itself. When you boil the wood it softens the lignin and allows the bound water to leave more quickly and with fewer cracks. I use a metal garbage can on a turkey cooker. I boil them for about an hour. I then use pentacryl while it is still hot which really gets the pentacryl to get sucked right into the wood. My last batch of bowls I boiled between a month to a month and a half ago and they currently stand at 5-8% moisture. They are ready for finishing. Thanks for watching!

[@gordcameron4409]

Nice work. Do you find that the circular steady gets in the way of the laser bar?

[@BrailsfordWoodworks]

Thank you Gord! I have found it gets in the way a bit. I saw someone using my hollowing system and kept the laser supports at an angle to avoid one of the wheel mounts. I may try that.

[@dougdrown4020]

When are u doing next one

[@BrailsfordWoodworks]

It is done... this the finished product... kzbin.info/www/bejne/g4TNlJZ6a76frqc Thanks for watching!

[@joepark6390]

Looking forward to part 2. Will u send out notice to subscribers?

[@BrailsfordWoodworks]

Thank you Joe! That video was posted on July 30th. Here is the link... kzbin.info/www/bejne/g4TNlJZ6a76frqc

[@jackthompson5092]

Can’t wait to see the finished hollow form Mike. This is the first I have heard of boiling a piece. What exactly is this supposed to do for the wood?

[@BrailsfordWoodworks]

thanks Jack! I would tell you what I have learned but watch this and you will get the best explanation I have seen... kzbin.info/www/bejne/mWOcmaZopL1kqtk

[@thewilliamsstudio2508]

? What’s the purpose of boiling the wood? How long do you boil it for? How do you dry it after the boil & how long does it take to dry? Thanks great video. Todd

[@BrailsfordWoodworks]

Thanks Todd! Watch this video for the best explanation I have seen... kzbin.info/www/bejne/mWOcmaZopL1kqtk

[@profeslessonsandvideos402]

What rpm do you use for the hollowing out with the Forstner bit?

[@BrailsfordWoodworks]

typically about 700rpm.

[@jeffscott198]

I have two questions about your deep hollowing video. First, how deep do you consider "deep hollowing" to be, and how deep does a hollow form need to be to require the use of special deep hollowing equipment? I have some long handled skews I use for hollow forms, but I have never used a "captured system". I've never worked on a hollow form that is deeper than 12". Second, I understand the need to keep the wood wet, so it won't crack, but what is the purpose of boiling the water?

[@BrailsfordWoodworks]

Hi Jeff. Thanks for your excellent questions. I would say 12" is about as deep as I would go with hand tools. This vase is over 18" deep. I always drill first, then use my carbide hollowing tools. When I get as deep as I feel comfortable going 10"-12", I then go to my Clark Deep Hollowing system to the full depth. As for the boiling, it softens the lignin and allows the captured water to be released faster and with less cracking. Thanks for watching!

[@ClintHitchcock]

Thanks for sharing. How long do you have to boil the wood for? Do you let it dry before the 2nd turn? Interested in seeing the final vase.

[@BrailsfordWoodworks]

Thanks Clint! You boil one hour per inch of wall thickness. I will likely boil this one for an hour and a half. Then yes, dry before the second turn.

[@trurex007lee7]

I have never heard of submerging a green turned bowl/ vase in water. It would definitely keep it from cracking but what happens to the shape after twice turned?

[@BrailsfordWoodworks]

Watch this video. He explains it very well... kzbin.info/www/bejne/mWOcmaZopL1kqtk Also in Spindle orientation I will be getting far less distortion when it dries. Boiling the wood will help prevent the cracking. Thanks for watching!

[@Atomic.woodturning]

What camaras do you use in the shop?

[@BrailsfordWoodworks]

I have two GoPro 5's an 8 and a 9. I honestly like the 5's the best. The 8 & 9 both overheat easily. They both have great motion stabilization, but that really isn't needed for wood turning.

[@scottnewsom7572]

Where is part two?

[@BrailsfordWoodworks]

Sorry that I did not make it clearer in the title. My mistake! kzbin.info/www/bejne/g4TNlJZ6a76frqc

[@scottnewsom7572]

Thank you!@@BrailsfordWoodworks

[@willielabuschagne1208]

Hell pal, it takes you 16 minutes out of the 24 to even start getting to the topic.

[@BrailsfordWoodworks]

In my opinion, shaping of the vase is all apart of the project. Sorry if you feel you wasted your time. Have a great day.
