I get annoyed when WW2 documentary videos, sometimes on TV, show completely incorrect machines being used. It often varies with the individual documentary and if it becomes to flagellant I turn it off. Identifying German "pocket battleships" as belonging to other countries and showing B29...

I like sundials. When my wife was a teacher, I built a sundial for her class. With longitude correction, time of year correction (the figure 8 printed on some globes), proper latitude construction, and proper setup it was accurate within less than 5 minutes error. Get a good reference on this...

The Eccentric Tool holder is great for turning and threading. It clearly put much less strain on the lathe and makes it very good for non professionals. I supervise machine shop labs for a University with a BSME program (among others) and bought 2 out of my own pocket because it makes machining...

Glad to hear you are doing well. About 15 years ago I had a chance to visit the Stryker facility in New Jersey. They make things like knees on some very nice and clean CNC machines. As machine shop type people, we would probably marvel if our Doctors would show us a video of the manufacturing...

In the late 1960s I was working in a small machine shop. One machinist, during WW2, worked for Curtiss Wright making B29 engines. He told me CW had their castings rough machined and then stored them outdoors for about a year before final machining. This was in New Jersey so metal stored in the...

It is my impression that once the small (high speed) flywheel is disengaged from the aircraft engine no gears in this system are engaged with whatever noise they make. I any case, the unmuffled Mercedes or Rolls-Royce engine should be many times noisier than the gear train. In addition, the...

I have seen quite a few videos on WW2 German ME109 fighters using geared flywheels on their Mercedes engines. I think they were also common on Rolls Royce Merlins. For your use, just design a twist out engagement mechanism as soon as the engine RPM exceeds the flywheel RPM. This is fairly simple...

I forgot to mention. You must turn down the bar the bar in the chuck before using the indicator. This will insure the outside surface of the bar is perfectly parallel with the lathe axis. Now you use the dial indicator, compound twisting and traveling procedure. Do not run the lathe when using...

According to my American Machinist Handbook, vintage 1945: Big end diameter=0.700, small end diameter diameter=0.572, and taper per inch=0.049951. Use a dial indicator and turn your compound around until, with a compound travel of 1 inch, you get a deflection of 0.049951 inches. The same data...

Great work! If you ever get to the NYCarea, I'll buy you lunch and we can talk about you incredible project.

Very strange wording and sentence structure. The reader base here is not, usually, English majors but this looks, to me like poor, unedited, robot talk.

Regarding your cancer. I had surgery and radiation treatment for prostate cancer 24 years ago. I wish you good luck. I hope you new lathe will be a good fit for your needs.

Now I understand. I too am 75 and I recently sold my nice, but heavy, Walker-Turner drill press and my Delta Toolmaker Surface grinder. The grinder was a difficult item to sell as it had to be completely disassembled to get it out of my basement and surface grinders are not to common in home...

I must be missing something. Your wife wants you to downsize your lathe for health reasons? You only need to turn wheels to operate the lathe. It is hard to see how this would be a health problem.

Your grandsons welded tables for the surface plates are beautiful. You have something to treasure.

Here is a You-tube Video on the Otis King Calculator aka slide rule.

I checked their web site on 12/28/22. At $443.79 for a KnKut 29 piece set 1/16"-1/2" I will will pass on these drills although they may be perfect for other people.

I have not made spark plugs but I would assume potentially different theramal expansion rates between the insulator and the center electrode and the insulator and the insulator and the outer steel housing could be a real problem and cause plug failure. For instance if the center electrode has a...

Hi Guys, About 1967 I had the privilege to work with a machinist who worked at Curtis Wright making B29 engines. He said it was Curtis Wright practice to rough machine the cylinder and put them outside for about a year. In NJ that means temperatures from about 0-10 degrees F to about 100 degrees...

She is awesome! When I ran a Plant Engineering Dept in a big printing company, years ago, I would have hired her in a instant if she applied for a mechanics job. Fantastic!
