AC contactors need to have the pole pieces in intimate contact or they hum loudly and draw more current which can burn them out. I’d bet the pole faces...

We had our electrical shop wired with a big contactor tied to the lights. Three reasons, saving power because all lights were on multiple contactors....

Saw something at my new job today. A single large VFD with contactors on the output to run one large spindle alone, one small spindle alone or 3 or 4...

Step jaws require a movable jaw that can’t tilt because all the load is at the top of the jaw, and it will rise every time. On a Kurt the movable jaw...

The real reason you need twice the size is only partly that 2 phases are supplying all the power, that part was easy to solve. The bigger problem is that...

I built something very similar for my table saw to safely cut aluminum on compound angles. Mine has a guide rail on the bottom to fit the table.

You can leave any metal in a dilute acid and it will stop removing any metal as soon as the solution reaches saturation. I learned this when we jar tested...

Router, high speed, go carbide. I get US made 2 flute end mills in sizes from 1/8” to 1/4” for less than $20 each. I like the Kyocera 1/8” end mills....

My home built CNC mill has 3 identical 18” travel THK linear rail slides and ball screws and I have a spare in the closet. Paid $1200 for all 4. A steal...

The disks were made from magnesium with an iron coating. 1/2” thick but amazingly light. I took one apart. Like a 5 hp spindle motor.

Actually the best shape for that cam is an archimedes spiral. An archimedes spiral is self locking on every point of the curve not just top dead center....

You might look at FolderMatch. I used to use it to keep my desktop and my laptop synched before and after field trips.

If I were going to want to clock the ends to match I think I would put the shaft in a V block and machine a tiny flat across center at both ends in the...

No kidding, I had one of the same machines! Bandit controller with digital displays and blinking lights no CRT or screen. I cut a lot of parts on that...

I can do that on my homebuilt minimill CNC. The head on my machine moves not the table so I can mill, drill or bore on the end of a part 20 feet long...

7 might be a morse taper tap holder if it has a square socket at the bottom. They work real well when combined with a reversing VFD spindle on a drill...

A Bridgeport is nothing if not versatile. Not the best at anything but can do almost anything well enough.

[garyhlucas]

Caustics like Sodium Hydroxide or Potassium Hydroxide do a great job of removing aluminum from drills, end mills and files. I keep a container on the...

Since I am not working at the moment I might go on Saturday. It's about a 2 hour drive for me. I've been twice before when it was in York. That's m...

Jim,
Good for you! May you die quickly, not soon. Watched my best friend go from looking like Arnold Schwarzenegger in his prime to 100 lbs from...
