something something silk purse something something sow's ear. I'd be thinking about how to add a high-speed spindle to the mill.

That's one of the ideas that came to me too.

I had them made in China. Just googled making puzzles from photos or something to that effect. It wasn't even expensive. This was 500 pieces I think. I wasn't impressed with the quality of the colour. The puzzle was much pinker than the original photo.

Thanks for the idea. I'm going to get some of my Wifes yarn colour gradients made into a puzzle for a Christmas gift for her.

The upside of the lions gate bridge puzzle was that there is a numeric grid printed on the back. The actual die to stamp out the puzzle pieces (which are thin plywood) duplicates the pieces way too much. As in there are way to many pieces that fit in other places. Likely because it's a cheap puzzle. But the numeric grid on the back helps with that.

In the past I’ve had to file the two tabs because at some point the company making them changed the molds ever so slightly and now it takes a huge amount of force to press the connector into the box. It deforms (Compresses) the plastic tabs. The problem is if you have to take it apart you pretty well break the box as it’s really hard to deform them for removal.

So I thought. Crap. I have a mill. I have to do 50 of the puppies. I don’t feel like filing them all. So with a bunch of manual jogging and noting XYZ positions and doing a few manually I now have a G-Code program.
So much easier.

Going through some older Model Engineer magazines I ran across this. Looks interesting and would be much easier to build with CNC on the mill. I've attached a link to the two articles as a 300 DPI PDF which is too large to include in this forum.

Since @David has a CNC mill and he's so quick I'm thinking I can pick up the one he'll make for me this coming Friday?

Wow thanks for posting John.

If I could find my CNC mill you know I would!

Here's another scan this time of what the British call things and what we call things. Helps when reading British Articles.

Finally got around to making some table covers to keep the crap out of the T-Slots. The tool height tester caused a lot of issues. First time, measured incorrectly. Second time too thick in one spot for the nut that captured the cable. Third time a nice fit but too far back so the T-Slot guides didn't fit.
Finally gave up and made a round spot for it. I can make a new insert now that prints faster and the angle of the rectangle isn't important.

Thanks. I have a Pharmacist wife. He had a brand new kit in his bag. He'd been Narcanned twice that evening. Even so fatal quantity in his blood. As the coroner told me today is that even in the hospital with all the gear they still lose patients to this.

So sorry for your loss

My utmost Condolences

For anyone who wants to make something similar here's the step files. I inserted a plane and then extruded/cut in either direction to create the half pieces. They just fit into the Bambu printer. The rails and dowels were printed on the SOVOL. The plan was also to make a rectangular insert that fit in the end of the mill table but instead I have a hole in the end of the rail and I can just insert a bolt that presses against the end of the table.

Once I create a nice insert for the tool height sensor I'll glue the pieces together and prime/paint. Maybe an epoxy paint to deal with various coolants or lubricants.

Yes. Over kill....
