My Home Made Scoop Chuck For Difficult Mounts

This scoop is actually my Vicmark vm120 body with wood jaws mounted to the body.
The jaws are made from an 8" by 8" by 1/2" piece of Baltic birch plywood(the good stuff). The standard jaws were used as templates to mark bolt holes. The holes were then counter sunk and stabilized with thin CA glue.
The jaws are attached with bolts a little longer than the standard bolts to allow for the additional thickness of my plywood.
On top of the plywood, I glued 2" thick cedar since that is what I had available. The wood can be anything stable and readily available. This wood is miter cut similar to a picture frame, drilled for outer bolt access, and glued to the plywood.
The jaws can now be customized to hold the current project.
For my scoop, I drilled out the center a little smaller than my scoop bowl and removed two opposing jaws.
When the time comes that I have removed too much of the jaws for my then current project, I can either make a new set of jaws or tool off the cedar and glue on new wood pieces.
As with any home made tool, please be careful and use your head. Start slow then increase speed to where you are comfortable then dial back a little. As with any home made tool, you are the sole person responsible for its safety and your own safety.
Good turning.

You cause me to spend lots of time, not only watching your videos, but also trying to duplicate your projects/gadgets! Thanks - hope you keep it up.
Robert Horn Ain't life tough! :) :)
Alan
Beautiful video, Alan.
Thank you for sharing.
It's pretty easy so a spoon chuck after assemble.
Günter Schöne Thank you Gunter
Alan
Love your simple use of every day materials I was looking at buying a cole jaw but I'll now make my own again Thanks From Australia
You are welcome Australia. :)
Alan
That's a great way to tackle the scoop project. It makes the spinning handle a lot safer.
What's up Wayne Depends on the angle you have for the handle.
Thank you Wayne
Alan
Great idea Alan, good video well demonstrated and explained, Best wishes. Harry
The Little Garden Shed Workshop Simple is good. Thank you
Alan
That chuck seems so very versatile Alan, thank for telling us the method you use to make one.
Take care

Bonjour Alan, très bonne idée. Merci
Laurent Cortot Mais oui, Laurent.
Merci
Alan
Fantastic ,Alan ! greetins from Valdivia Chile .
+Wladimir Americo Rogers Esparza Rodriguez Welcome Chile.
Alan
Thanks for sharing how this is made. Now I know what to make with my bb plywood.
John
John Stegall What to do with bb plywood has never been a problem for me. :) Other than does the project justify the expense.
Good turning.
Alan
So easy to like this video. I want to make a hand mirror and need jaws that extend to 125mm diameter. I only have one chuck and two sets of jaws so this will be a very beneficial project. Thanks Alan!
Perfect! go for it.
Alan
Excellent idea Alan! and thank you for sharing
Cheers Bram
Brams shed You're welcome.
Good turning.
Alan
That's a good addition to a scroll chuck to have, I'm sure it will be useful for lots of projects.
Andrew Stevens I have no doubt there are many applications. Please let me know how you use it.
Alan
Great video, Alan!!
Thanks for sharing.

Great project Alan
I use my very frequently.
Very useful
Alan
Excellent...
Cheers...
Adam Quincey Thank you Adam
Alan
Great job.
Richard Katzman Thank you Richard.
Alan
Got to make a set of these, great idea. Much safer than the metal jaws too.
+Lynn Schmidt Yep, the wood jaws are tool friendly.
Alan
Making a scoop chuck means I need to make cole jaws too. Making cole jaws means I have to hang a plank of wood on my wall so I'll have where to store all my new chuck attachments. To get a large plank to have on my wall I'll have to drive to the hardware super store near the airport. Driving in this heat to the airport means I'll burn to a crisp in the baking sun in my black car. Is that really what you want Alan??!! :) Thank you for a great video, going to make me some of these!!
Yuval Lahav Perhaps you should wait until Fall! :) No crispy woodturners allowed.
Alan
I chose your design because it looked the safest. However when I tightened the jaws, the screws pulled the plywood apart. I tried three different ply woods and had the same problem. Still like the design, would like to offer a suggestion for those folks with a Nova chuck. For $19.95 you can purchase a 'NOVA 6021 Soft Chuck Accessory Jaw Set" from Amazon and mount your wooden jaws on the jaw set instead of PLY wood. The nylon jaws are made to modify for any configuration you need.
Great suggestions for Nova chucks.
Meanwhile, what plywood did you use. I used Baltic birch plywood. Common plywood just is not strong enough.
Alan
I used birch ply wood and hard board. I rebuilt this three times before settling on the Nova 6021. I have not seen the Baltic birch in my neck of the woods (SC). Anyway, the 6021 work great forme and still use your basic design. Thanks for the email.
Let me summarize this discussion for others who read this thread.
Charles' original jaws failed because the screws pulled thru the plywood. He found a great solution with the NOVA Soft Chuck. So he is off and running.
Why did his plywood fail? Not all plywood types are equally strong. Some types are very weak and should not be used.
1. Common fir plywood has few, thick plies and many voids. This should not be used for this project
2. Most Hardwood plywood is similar to fir plywood. The only difference is the outer plies are hardwood. This should not be used here.
3. Hardboard, particleboard or MDF core plywood is heavier and no voids. However, the core does not have the strength for this application.
4. Baltic birch (or other similar names) has many thin plies and no voids. It is significantly stronger than the other woods noted. However, it is still wood and not as strong as aluminum or steel. It was adequate for my jaws but I applied CA to the screw holes and am very careful not to overtighten. Then use only at low speeds and avoid standing in the rotational plane.
If your chuck is a Nova chuck then use his solution.
Where did you get the bolts to fit your particular chuck? I'm having trouble locating any.
blufour44 You will not find them in a regular hardware store. I went to a commercial bolt specialty outfit, Oregon Bolt & Screw. There are many like them in our area serving bulk commercial interests so you'll have to find one that will deal with you for the number you need. I took in my old ones and said I needed same thread and head but longer.
Good turning.
Alan
Thanks! Quick reply.
Great project Alan. Is the wood for jaws pine?
Terry Vance I used some Cedar that I have a pile of. It was available.
Alan
Can anyone point me to the egg Chuck video?
I’m looking for ideas 💡

Добрый день меня зовут Александр, я из России, хочу Вам предложить одну идею, изготовить деревянную трубу где внутренний диаметр , должен быть равен 50 центам, ( евро ) а один конец трубы должен быть наглухо запечатанный, но другой иметь прорезь для опускание монет. Получается копилка . Длина трубы ,,копилки,, может быть разной. С уважением Александр
Александр Качалов Thanks for the idea for a coin sized piggy bank.
