Hi You have done a nice job of explaining the process. I am not sure why the threading. I have made a couple dozen file and wood turning tools. I epoxied the handles on. If I decide to remove one handle and replace it I will grind the wood off with flap discs and wood rasps. Then glue the next handle on. I made my handles on a wood lathe from local hard woods.
You're right, of course. If I just wanted to attach a handle, the taper would be sufficient. I want to have a threaded socket at the back end of the handle to attach other accessories (like a large knob or pad to brace against my body). I want that socket connected steel-to-steel, all the way through to the tang, hence the more complex design with the threaded insert.
Hmmm.... I wonder if you can patent the idea.... not to keep the home gamer from doing so, but to prevent Gri22ly or one of the others from doing so and turning a profit off of your process... I'm sure it's been thought of before, but personally, this is the first time I have ever heard of 3D printed sabots for through spindle turning...
A patent might be possible here, but getting a patent for this would require tens of thousands of dollars and a decent IP lawyer. It would most certainly be rejected initially by the examiner as obvious to one skilled in the art and sent back, requiring more dollars and lawyers and time. In the end, if it could be obtained, I'm not sure what the value would be.
Asserting a defensive patent to keep others from claiming rights over an idea can work, but as James says it is expensive. If that is the goal (rather than trying to financially profit from an innovation), presenting the method via complete public access to establish it as prior art is far more cost effective. Regardless which route one takes, a legal battle to defend either intent will be vastly more expensive than even filing a successful patent. So! If you can't afford the patent process to begin with, you certainly won't be able to afford defending an innovation in court. Best you can do is lay the groundwork for someone with deeper pockets to contest it.
Amazing channel - perfect blend of design intent/ Fusion and machining - congratulations Sir and thank you

Dennis, I think he was responding to you...

Why not weld up the end, and then turn it round?
Great video as always :) you should have a lot more views!
Thanks! Feel free to tell all your friends. :)
Wow.... real WDITOT moment! You just wiped out any plan I had to make a dedicated spider for each of my lathes... MUCH more stable and precise.
James I am interested in buying the handle can you make an extra?

I'd be happy to. Let me work out the cost and I'll put up an eBay listing.

I like your videos but only wish you would make it with tools that the average home shop has. Not many have a 3D printer.
Clough42 _ Great video!
Thanks!
Smart
Thanks!
Could you have forged the end of the bar enough to give you a round, full contact thread?
Or TIG weld onto the end.
