    Show us a magnified, head-on view of the crack. That way we can look for signs of fatigue. I am skeptical of a fatigue theory, because there should not be much cyclic loading in a flywheel bolt....

    I see two right-angle heads! You really did score. I wish I had one. If you have questions about either the F4 or F5, ask. I have both and have been inside them. Anybody have an extra 6-T-slot F5...

    Read the code handbook. If you are at all unsure about this, hire a licensed electrician. If you don't have a ground reference on the RPC output or the 600-V output, those voltages are unpegged...

    NBU 15 has higher speed and temperature rating than Super Tel, so the only reason to use Super Tel is if you are into concours restoration and operation.

    In other words, why pay more money for a...

    You are saying 6 out of 1000 people (that's .6%) who get a flue shot die from it? Who knew? Where did you get this gem? Imagine that. I work for a company with about 1000 employees, and every fall my...

    I don't think that is right. There is Te, Se, or S added to enhance chip breaking, and the heat treatment is designed to get uniform properties all the way through the section with minimal residual...

    I've used ETD-150 for horizontal mill arbors and slitting saw arbors with no issues. Avoid sharp corners and make the thread endings (pullouts) smooth. It's hard to picture much load, fatigue or...

    The little squatty five does not look squatty on my DigiMatics. Of course you could argue mine are counterfeits. It never occurred to me that I should suspect them. Mine are 4", but use the same read...

    The largest screws are 0-80. Wow! George gets tremendous respect from me for not burying bad finish and mistakes under paint. The soldering ain't too shabby, either!

    It's the latter. I use Fusion 360 with a modified post. I modify the text file that the post spits out in BBEdit on my Mac and then upload the whole program in D4 Mode 14. BBEdit lets me renumber...

    Nicely done!

    BTW, I use local subroutines all the time. I put any G41...G40 compensated contour segment that I want to cut more than once in its own local sub. I keep the feed and speed in the...

    My lathe has one of those grease nipples. I just made an adapter with a Zerk fitting on one end and a countersunk hole on the other that I press down on the fitting. It's a bit of a three-handed job...

    Zoro seems to drop-ship a lot more than other vendors, which would explain why they don't combine shipping. I am pretty happy with Zoro's prices. I prefer Zoro to MSC for sure. Zoro lets you search...

    Couple thoughts on the noise. One is the Roots blower. That puts out a roar. You get a similar sound from a vacuum truck. Another is that the exhaust valves may open at higher combustion chamber...

    The flex chucks are lousy for short workpieces. The other problem is that the collet is recessed back from the chuck nose. This makes it hard to turn small-diameter stock with minimal stick-out....

    Back in the late 60s you could buy a Chevy C-50 (maybe C-40 & C-60, too), with several gas and two diesel options. One diesel was a V-6 throwaway, whose brand I forget, and the other was a Detroit...
