Woodturning Tricks & Tools - David Marks GIANT Hollow Vessel Presentation

In this video presentation David Marks shows us his method for turning very large hollow vessels on the lathe right from the start. The scale of this woodturning project is amazing! The blank for this turning project weighed 400 pounds and the tool he used to turn it weighs 125 pounds! David also shares his incredible for secrets quickly drying wood while preventing warping, checking, and cracking.
I met with David in January while he was still in the early stages of turning this huge hollow vessel. His deadline for completing this piece was to have it completed in time for the 30th annual American Association of Woodturner's Symposium. The symposium was in June of 2016 so he only had a few months to get 400 pounds of wet wood turned, dried, finished, and rubbed out and shipped from California to Boston.
The magnitude of this project is much bigger than it appears and it took David over 1000 hours to complete it!
The end result was a true masterpiece. David named the piece Sensei. Sensei means "Teacher" in Japanese and he chose that name because he learned so much from this project.
If you are looking for a showpiece for your living room or your corporate headquarters then you are in luck because remarkably, this piece is still available.
David wrote an extensive and very interesting article about this piece and I strongly encourage you to check it out!

Hi guys that's a great job on that vase, I turn hollow vessels and vases some 20" deep. I haven't buillt a boring bar yet but intend to in the next short while. For now I have a chain loop attached to the bed of the lathe with a big ring on the end and I slip the handle of the tool thru the ring and that takes out the jerking and grabbing action and allows movement in and out of the vase. It works pretty well for a quick fix. When I need to hurry the drying process I rough out the vase or vessel to about half inch thickness and wrap it with shrink wrap about four or five layers. I then set it upside down over an old computer cooling fan that has its own stand so it can suck air and push it into the vase.This allows the item to dry from the inside first without cracking the outer shell. The shrink wrap keeps the wood tighter as it dries. After a few days of intermittent drying I take off the wrapping and check for moisture and rewrap if required. Works for me.

Now this not something you get to see every day! Thanks to you and David for sharing!

[@JackbenchWoodworking]

Thanks! I am glad you liked it.

[@summerswoodworking]

Man you hit a home run this interview. David Marks the master!

[@JackbenchWoodworking]

He sure is! Thanks Brian.

[@cigarsmoka9741]

Just a great video and interview with a true master. His old television show is what got me into woodworking. That hollowform is an amazing work of art. I really enjoyed this one, thanks for sharing!

[@JackbenchWoodworking]

Thanks, and I couldn't agree more! His show was probably the best woodworking show on TV, period!

[@plakor6133]

Unreal. Thanks for posting.

[@JackbenchWoodworking]

Glad you liked it!

[@gushall708]

Another Great Video! I had to come back and revisit! So much VALUABLE information from such a GREAT Turner! Thanks for Sharing Charley! Have A Super Week!.....Gus

[@JackbenchWoodworking]

Thanks Gus! David is a great turner and a really great guy, too. Glad you enjoyed the video!

[@MRrwmac]

Amazing video! A great opportunity for you and you shared it with us! Thank you! Exquisite piece of art and master craftsmanship by the world renowned David Marks!

[@JackbenchWoodworking]

I 100% agree with you. Yep, it was an amazing opportunity! Thanks!

[@billbunch9837]

Cant wait to take his class this October

[@JackbenchWoodworking]

I am hoping to take his patination class in December, but I am not sure if I can pull if off. Have a great time and please tell David that I said Hi!!

[@ragtie6177]

A fantastic interview & video. The Vessel is phenomenal. The process even more so

[@JackbenchWoodworking]

Thanks man! Hope you are recovering well my friend.

[@AndrewKleinWW]

This was a great video, very informative, I'd love to take a class from him.

[@JackbenchWoodworking]

David is such an friendly and easygoing guy. Yes, a great teacher!

[@danielsolowiej]

I very much enjoyed this video. Plus lots of useful information, Thanks so much !

[@JackbenchWoodworking]

You're welcome, Daniel. Thanks for watching!

[@willemkossen]

That was awesome! Great interview, great person, great turner! Love it!

[@JackbenchWoodworking]

Thanks Willem! Yes, emphasis on "great person" because he really is.

[@crazyrussianwoodshop3957]

Unbelievable, Charlie!! Great coverage on that stunning project!! Love it!!

[@JackbenchWoodworking]

It was great to spend the day with him, glad you liked it Michael.

[@crazyrussianwoodshop3957]

It is certainly a masterpiece!!

[@mcremona]

Incredible. David is amazing

[@JackbenchWoodworking]

Yes he is!

[@stevecollins9450]

Very interesting. Thanks Charlie and David.

[@JackbenchWoodworking]

Thanks Steve!

[@MauriceBlok]

Yes! Enjoyed it, whoa

[@JackbenchWoodworking]

Thanks Maurice!

[@crackerjack3359]

Really informative and a great piece. You said you didn't really need the safety glasses and then took the off to blow the chips out. That's when you needed the glasses. Thanks again (Montana Wood Art)

[@JackbenchWoodworking]

Thanks!

[@johnfordham9791]

Thanks, great video. Really nice guy, both of you. I work smaller, but admire such a process...

[@JackbenchWoodworking]

Thanks John, I am glad you liked it!

[@TurningRound]

Thanks for this video, that is an amazing turning.

[@JackbenchWoodworking]

Thanks! David is an amazing guy.

[@thomastieffenbacherdocsava1549]

Beautiful!

[@jb121993]

What a fantastic video! I've done one hollowing in the past of a piece at 1' diameter @ 5" tall. After nearly browning my pants 3 times, I chose not to try this again. The explanation of tool mass, in relation to depth and friction has sparked up an desire to get back into this.

[@JackbenchWoodworking]

Thanks!! David really knows his stuff and he is a nice guy, too!

[@BraxtonWirthlin]

SO AWESOME, CHARLIE! What an amazing interview! Very well done! Lots of cool info and tons of insight on how he turns stuff like that. I've got to get up to Santa Rosa and take a class from David.

[@JackbenchWoodworking]

Thanks Braxton! David is REALLY a great guy and you would definitely not regret taking a class (or two) from him.

[@tompritch56]

That was a fantastic video. Thanks for putting this together. I would love to take one of his class's someday.

[@JackbenchWoodworking]

Thanks Tom! David is genuinely a nice guy and any classes with him would be great.

[@ragtie6177]

Phenomenal piece.... Excellent & entertaining interview Charlie. I loved the episode.

[@JackbenchWoodworking]

Thanks man! David is an amazing and remarkably nice guy. He sent me some DVD's of his Woodworks tv show for me to give away on my channel. I will plan to do that in the next week or so.

[@ragtie6177]

pure awesomeness my friend.

[@DerekCadmus]

WOW! Most fascinating!!

[@JackbenchWoodworking]

Thanks Derek!

[@thomastieffenbacherdocsava1549]

Wow and Whoa! What a great presentation and great sense of humor. I see where you might have gotten the alcohol treatment of wood? Thanks for doing this Charlie

[@JackbenchWoodworking]

Thanks Tom! I am glad you liked it.

[@imaginegrove]

well done and good information. FYI - add acetone 50/50 to the alcohol and you'll dry faster.

[@JackbenchWoodworking]

Thanks Scott. Nice tip on the acetone.

[@juliocesarmoralesabanto6291]

Un trabajo fantástico,y tu herramienta genial,felicitaciones.

[@JackbenchWoodworking]

Thank You!!!

[@DadbrosGarage]

I'll stick to making my bowls and platters haha. Forget those huge pieces.... lol

[@JackbenchWoodworking]

I know! Those vessels are a lot to handle!

[@robertcornelius3514]

David's health is getting away from him. He was really choked up. Everyone start using their dustmask.

[@robertcornelius3514]

And a big thumbs up for Charlie's video. I'm sure we would like to see more of them in the future. :)

[@JackbenchWoodworking]

Thanks Robert, I will do my best!!

[@thomasckuzia7129]

Truly amazing piece and informative video! How does one sand the inside of a piece like this? Tom

[@JackbenchWoodworking]

Thanks Tom! If sanding is necessary then I "think" he would adhere some sandpaper onto a stick.

[@akwekful]

Amazing piece of work. Wonder what he’d charge for something like that? Over £20,000 surely?

[@JackbenchWoodworking]

Thanks, I think you're right, something that nice probably won't be cheap.

[@akwekful]

Says over a 1000 hours! I must be light on that guess!

[@CyrusTabery]

Everything was good but the inch per year myth is wrong for drying time. Water transport is quadratic with thickness. That is if an inch is a year then a half inch will dry in 3 months and a quarter inch will dry in less than 1 month. I understand the process he is using but people may want to understand that 2 inch thick may take more than 2 years to dry. Anyway great show!!

[@JackbenchWoodworking]

Thanks Cyrus

[@carlwood6532]

hi what lathe was he using to make that vessel

[@JackbenchWoodworking]

It was a OneWay, but I don't know the model.

[@bobleeswoodshop7919]

Hey Charlie , are you going to the WIA in September Regards BobLee

[@JackbenchWoodworking]

Hi Bob, yes I probably will attend WIA this year. You going?

[@bobleeswoodshop7919]

+Jack Bench Woodworking Yes I am . I hope to meet you and other KZbin people Regards BobLee

[@cattleNhay]

Something that heavy does not come flying off the lathe, David …it just drops. Maybe check your science again?

[@RunCircusRun]

Sure, ok. Uh-huh, yeah sure.

[@JackbenchWoodworking]

Yep!

[@JackbenchWoodworking]

Cyrus Tabery Hi Cyrus, I think you are right. David was speaking in very general terms.

[@carrieabailey]

What is the actual drying time then? Does it depend on type of wood?

[@stephenhomfray9935]

David has given everyone a good starting point it's up to you to now individualise your system to suit your needs there are many different methods for drying wood lumber turnings carvings
