My daughter wanted a "Thor" hammer keychain, So here's what I came up with from some round and some 5/8" stock. Still have to drill for the keyring.

zmotorsports, Question, What happens when a butter fingers like me drops it and the bottom gets dinged up. Me, I would wind up needing to reface the bottom or top then the height would be off on it. I thought about making one like that but was trying to figure out how I could solve the problem if needing to reface it. Any ideas.

Put a steel face screwed onto the bottom for bump protection.

Finished up my internal threading tool and holder today. It works just fine now that I redesigned it a little. With the top of the insert at the center line of the spindle the bottom of the insert would contact the work before the cutting point would even though the insert has a 7 degree relief angle.
I put the bar in the mill and took an additional 7 degree cut on the top and bottom of the bar so the insert would now be tilted 7 degrees. I wasn't sure how this would work but it cuts fine and it now has 0.010 clearance at the bottom edge.





Thanks for looking

Very Nice ! Did you happen to get a video of the thread milling? I need to learn more about that.

I was in "fixing my truck" mode today, and one of the things I fixed was the door handle for the rear suicide door on the drivers side. I use it quite a bit, particularly in the winter, and the handle regularly breaks. The assembly is primarily plastic, and the handle you pull on rotates around a pin, and a slab of plastic on the other side of the pin presses against the mechanism to unlatch the door. So, you pull on the handle, and the plastic pushes against the latch, and then you pull the door open with the handle. However, if you pull on the handle too hard (either just to open the door quickly or if the door sticks closed, say, being frozen shut in winter), or just through use, that plastic slab bends/breaks off, and you have to buy another one for about $50 for a knockoff or $100+ for an OEM one. Every year I've had the truck, I've had to buy 1 or 2 of these, and the last time it happened, I already had a spare to install, but I promised myself when that one failed, I would fab up the handle out of metal so it wouldn't bust.

That day was today.

Here's the handle I made next to the busted one (that extension that is about 3/8" thick and 1" or so long is what keeps failing:


New handle installed in mechanism:


Installed in door:


Works fine and I think the plastic housing is bulky enough around where the pin goes through the housing will take longer before it fails.

And now I'm off to pick up my victory pizza.

My son wanted a project to be with me in the workshop (dad’s happiest day as he hasn’t previously shown much interest)
Being this time if year I thought a Christmas decoration would be a good project.


And the end result
