Todays Project - What did you do today?
Needed some replacement oil level windows for my newly acquired VN12 mill.

Found a suggestion online to use polycarbonate sheet, and sandwich it between 2 faced pieces of round stock (of the same diameter as the window you need) using a live center so it can be turned to size.
Had a bit of 1mm Lexan lying around, so tried it, and works well. only takes about a minute to make each window once you're set up.

The retaining ring from the mill, and a roughed out piece of sheet. Leaving the paper on both protects the material and helps to hold it in place.
   

Sandwiched in place, and turned to diameter using a sharp HSS tool.
   

A couple of finished windows
   

I'll get a couple of thin o-rings tomorrow and fit them.

Nice work Steve !

Reminds me when I used that technique to break a law about fifty years ago, LOL. I stacked U.S. pennies between the live center spud and the driver spud and turned the pennies down to the diameter of U.S. dimes, on the 6 inch Atlas owned at the time.

After a bit of deburring, they worked just fine on the vending machines at worked for products requiring 10 cents. Not a money-making project, ha-ha-ha, but kinda' fun and I always wondered about the reaction from the guy that serviced the machines and his boss.

That brought back a memory. When I was a metal shop student back in junior high school, we would put pennies in a button collet and shave them down so we could make two headed coins by soldering a pair of heads or tails together. Ahhh, the good ol' days.

A bunch of crew mates on the USS Coral Sea brought back Singapore coins to the states.  They were just close enough in size to US quarters that they worked in the old mechanical coin operated washing machines.  Sure POed a bunch of self laundry owners as they were worth about 10 US cents.   Big Grin

Allegedly in the steel mills you could hammer out lead packing of some sort and stamp quarter sized slugs with a sharpened piece of 3/4 pipe
Free advice is worth exactly what you payed for it.

These days it looks like instead of making slugs, the young folk have taken to teaching each other how to hack those 'grabber claw" machines in restaurant lobbies and arcades to clean them out of merchandise using only about $1 worth of quarters. Came across it on YouTube and apparently it's a 'thing' now. Rolleyes

Today, I got to install some parts I either made or modified, in a hard boiled egg facility. When under full capacity, they can hard boil, approx 50,000/hr or about 1.2 million a day, they usually average about 800,000 a day. I would call the place a shithole, but that would defame true/real shitholes.

OK, that makes me think of why people even started eating eggs.  The way I see it is that Neanderthal 1 turned to Neanderthal 2 and said. "I think I'll eat the next thing that comes out of that chicken's butt."

Sorry guys, more wood.
Bought some red oak logs for firewood, turns out at least a quarter of the log truck load were saw logs.
Started quarter sawing some today.

Unbelievable how much stress is in the partially dried logs, This is the lift at the end of an 8 foot log sawed in half, just before I broke through the other end. And you thought steel was bad for stress relieving.

About 150 board feet out of 4 logs, best is zero waste, these slabs go into the boiler. At the current $6.50 / board foot retail not a bad afternoons work.

Nice. It must have smelled great around there, processing all that Oak. Thumbsup
