And to be a Pain In The A** more pedantic , a 16 MHz clock is .0625 microsecond cycle. You correctly had that as 62.5 nanoseconds but then wrote the decimal as 62.5 microseconds. The Rarely Stated Laws of the Universe includes one that covers this. It's also included as a corollary of...

I think that's an excellent point. All metals are treated with various combinations of heating physical treatment. That's one reason for the image we all have in our minds of the guy pounding on red hot metal with a hammer. "Hammer forged" is harder. Unlike most guys in my line of work, I...

An answer on Quora says, "12.9 grade steel means that a component manufactured form this grade of steel has 12X100 N/mm^2 tensile strength and 9 is a multiplier means 90% of 1200 = 1080 N/mm^2 is the yield strength of the grade. "...

I hate Windows 10 with a burning passion, but have vowed to never use 11. (I have to buy Win 11 and then they use it to push ads on my desktop?) But that must be a different version of Solidworks. The website (Item 5 under "Questions? We Have Answers" says: "3DEXPERIENCE SOLIDWORKS (SOLIDWORKS...

If I'm seeing this properly, yes, it's a wet a crankcase and the bottom of the piston splashes through on every revolution.

I saw this yesterday and took a look at it; it almost seems to be in the "too good to be true" category. Does anyone have any experience with it? In particular, is it "real" Solidworks, or something different? I never used it at work, but I know it's approaching being standard now. Any...

I was dimly aware that stainless has a lower yield strength than "alloy" steel, although I'd guess in both cases the question is "which alloy?" Likewise, I'm aware that hex bolts come in different strengths and quality standards, shown by marks on the head of the bolt. If I had gone to buy...

I hope you don't think I was debating, ridiculing or doing anything less than studying what you said. You and I don't know each other, and to make matters worse, there's that quote about Americans and Brits being two people divided by a common language so that anything we say may be...

They're the best kind of screws: chosen for size from from a junk box full of random screws! More seriously, they seem to be stainless, but are likely to be made for a different purpose than holding a conn rod together. Probably 18-8 or 304 stainless. The extent of the information I have on...

As of this evening, the conn rod is finally done. I had transferred the rod off that fixture to drill the holes for the cap screws on the big end and cut the cap end off. Then I had to re-transfer it back onto that fixture to dill and ream the big hole on the right. I think I reset zeroes...

My problem is that since I have no actual training at all in how to do any of this means I pretty much only learn from my mistakes. To that point, if my drawings don't show a datum point, how do I pick one? Come to think of it, I might have done that on this part. As I worked on the...

Greg, That's what I do. Basically, any time I change the setup, I get concerned. Work holding is everything. I haven't adjusted the Y axis setting in the mill since I started working on version 1. A full month? I have reset X with an edge finder when I turned the first one over, and then...

The machining of the part proceeds with the milling done. It will be a precise drill press for the next operation and then drive a slitting saw blade. To answer my own last question, I did the final contour first in the position shown on the previous post - that required a tool change from...

Worst joke in high school physics 50+ years ago: "What's a joule per second?" "Yes! Yes it is." 1W = 1J/sec is an easy one to remember. Sorry.

I found the silly error in my Gcode for the circular bosses. I left off the negative sign on J= number on the circles that needed it. G91.1 G01 X0.907 Y1.000 Z0.125 F25 G01 Z-0.031 F6.5 G03 X0.907 I-0.406 F12 G01 X2.437 Y 1.00 G01 X2.437 Y0.502 G01 X2.937 G02 X2.937 Y1.503 I0.00...

The first operation went as smooth as can be. This was done with a 3/8 dia. carbide, 4-flute EM. My intent was to make it big and wide enough to get rid of all of the rest of the rough - and it did. I did the first two passes with compressed air coolant and cutting oil in the slot, then...

Second attempt about to get underway. I need to call the center of that left hand screw X=0.500 and Y=1.000 to use files I've already created. I think it's currently those coordinates, but I'll triple check that. I'm going to rough around the part with a bigger end mill and a contour cut...

Having been a ham radio operator since 1976, I have a desk drawer full of mostly foreign stamps I've kept. I'm just unorganized about it. No albums.

I never thought of dog washing. My fall back on "I'm going to start a less demanding hobby" was always stamp collecting. There are only two steps: Buy stamp. Paste in book. Neither can be done to even .001" Dog washing sounds easier, although probably messier. Probably depends on the dog.

And since I don't even own the simplest kind of welder, let alone TIG, it's ... academic. I looked at this part for hours yesterday. Yes, it might well actually be usable. Yes, it's going into an engine where it will never be seen so "ugly is OK." I just know I can do better, so I'm going...
