There's nothing quite like walking into the workshop with a tight production deadline, only to discover that one of your cutting tools has snapped overnight.
That's exactly the challenge we're facing as we work through a rush order of 150 custom pens, with just 10 days left to get everything finished and shipped.
And the timing couldn't be worse.
Threading is one of those machining operations where the condition of the cutting tool matters. The tool needs to cut the threads cleanly, and a damaged cutting edge can quickly become a problem.
Unfortunately, our threading bar didn't make it through the night.
The broken tool was covered in metal chips, and its cutting tip had chipped away. With the tool damaged, we also had to deal with the possibility of unusable parts.
When you're working against a deadline, it's not just the broken tool that's frustrating. It's the time lost, the parts that may need to be remade, and the work still waiting to be completed.
At this point, we've produced 100 of the 150 pens needed for the order.
That's a significant portion of the machining work behind us, but there are still 50 pens to go, along with the remaining steps needed to get the order ready.
The pens are receiving a Cerakote black coating, adding another stage to the production process.
With only 10 days remaining, every setback matters. Losing a cutting tool in the middle of production means having to adjust quickly to keep things moving.
One of the immediate priorities is replacing the damaged threading bar.
A close comparison between the cutting tools shows the difference clearly. One has a sharp, intact tip, while the other has a visibly chipped edge.
The replacement comes with a cost, too. At approximately $75, it's another unexpected expense in an already demanding production run.
We also use an LFV machining function to help break up metal chips during cutting, rather than allowing them to form long, continuous strands.
It's one of those practical details that can make a difference when machining small components.
Despite the rough start, the day isn't without progress.
By 6:58 PM, we're examining a freshly machined threaded component, and things are looking more promising.
There are still plenty of pieces to make and work to finish, but getting a good result after dealing with a broken tool is a welcome development.
With the deadline getting closer, we're continuing to work through the remaining production steps and see whether we can get all 150 custom pens out on time.
