Woodturning Acorn Box With Bayonet Joint
by Alan Stratton on Friday, December 31st, 2021 | 18 Comments
This post is best viewed right here. However, in case of difficulty, it is also posted on YouTube and FaceBook.
This is a fairly simple project but enhanced by using 3D printed bayonet bushings for the joint. Simpler would be to glue the two pieces of wood together.
The body is birch from a tree from my yard. The cap is walnut. They joint is wood infused PLA printed on my Prusa 3D printer. The finish is shellac.
Making the joint required Forstner bits and a little extra hollowing with a box scraper. A little bit of epoxy holds it in place.
Enjoy!
Where can I purchase the bushings you use in the Acorn Box?
I am working on sharing it via my Etsy website.

I am working on putting them on my Etsy website.

You talk about your 3d printer making to bayonet. Could you give a little demo on the 3d printer and how you design the part.
Thanks a great idea. Will do.
Alan
I enjoyed the video on the acorn my only question is where do you get the locking bushing you use to attach the top to the body
I am new to watching your videos band truly enjoy problem being new I have a lot of question
I will keeping watch
Thank you
Don

Bayonet mount? No 3D printer here, what’s my options.
I am working on putting them on my Etsy website.

More information about bayonet joint, please!

Hi Friends,
For those without 3D printers or threading jigs; find a source that sell the threaded inserts you want. Different sizes can be obtained online. Eg: Ron Browns Best advertises threaded inserts available for sale. I actually have a threading jig that can produce both regular threaded inserts or the newer Bayonet mount.
The interrupted thread Bayonet mount is really neat and is a surprise for most people opening your box.
I could make a few but shipping costs have reached amazing heights that most would not want to pay that much…
Peter, what jig is that?
He was referring to Chefware kits jig. But, I do not see how it could cut a bayonet style.

Peter, These are NOT threaded inserts. A bayonet definition:
A bayonet mount or bayonet connector is a fastening mechanism consisting of a cylindrical male side with one or more radial pins, and a female receptor with matching L-shaped slot and with spring to keep the two parts locked together. Wikipedia
You will see examples in camera lens mounts, specialty light bulbs, rifle bayonets, etc
What do you mean by an interrupted thread?
BTW. Ron Brown’s website does not currently have threaded inserts.

Reply for Michael P Kratky: I have the original prototype thread cutting jig form Chefware Kits. It is capable of 16 TPI, 10 TPI and doing either one in the bayonet style of joint.
I am glad I came back to check out the comments on this post.
If you need more info. Contact by email at pjfabricius@ g – – il. com
Thanks
Hi Alan, is it possible to notify commenters when a reply is posted? Thanks
Peter, let’s check our language and definition of a bayonet. Please see my other response.
I do not see how any current jig using a cutter could make a bayonet like what I am using. It would require a tiny cutter.
So, you may need to educate me.
Notification is not in my control.

Hi Alan, I am glad that I keep coming back here…. When I originally posted, there were three responses and I did not see that you were going to offer your 3D Bayonet Inserts on Etsy…
So, to explain my threading jig: I worked with Craig at Chefware Kits when his model was being finalized by the actual designer (forgot name at the moment). This jig is based on one that was actually from the UK and I also have that one and participated with that development, so I have been into these jigs for many years.
My jig will cut 16tpi or 10tpi like normal threads BUT I have an additional feature that allows two 1/4 sections to be cut away on both the male and female threads so it works just like a camera Bayonet Mount and closes / opens with a quarter turn. I can send you pictures by email if you like but cannot post pics here.
Thanks, I did not intentionally want to interfere with your ETSY sales project, sorry.
