Out of curiosity, I went and looked at the SDS for R123. One I found was from Chemours. R123 is usually non-flammable, but it appeared that under certain circumstances (mixed with air and at some pressure) it is flammable. And if you overheat it (I want to say the threshold was around 300...

WCE4: I don't know you from Adam, and I don't know what your beef or feud with Steamchick is, but your post comes across as you being a colossal @ssh@t. Why the venom? Because that's how it reads to an outsider (me). I only come here occasionally, inspired by Terry's V12 build. You both...

Failure is ALWAYS an option! It often has catastrophic consequences, but it is always possible, regardless of what NASA' Apollo 13 folks had to say. J

I've got some of the earlier arc fault breakers in my addition, as they were required. Went to put in all the trim (baseboard, window casings, etc) and found the my miter saw (with soft start) won't work on those CB's. Trips them nearly instantly. Ended up having to run an extension cord from...

Wow, this has been a wide ranging electrical discussion. And a couple of you guys have had some extensive experiences, some I'd like not to share (like Terry's garage fire) I'm not sure whether I can pick a winner on the fuse vs cb discussion. Fuses certainly have their place, but they can be...

I've seen aluminum exhaust manifolds for boats, but they are water cooled / jacketed. Not quite the same as is being discussed here. I believe Pleasurecraft and Crusader both use aluminum manifolds on their 6.0l boat engines. James

I believe Brian has made numerous sets of rings and is continuing to have issues with ring sealing. Hence he is thinking about other alternatives, such as having a ringless piston, or a tight fitting piston with rings. James

Taking 0.004" off of the OD of a part by grinding isn't too excessive. I used to work with a commercial tool and die shop, and we left 0.010" on pretty much everything as a minimum, to account for stuff moving during heat treatment. Saw a couple of pieces of D2 that turned into Pringles (ok...

If you have a toolpost grinder, yes, you should be able to use it to "sneak up" on your final dimensions. I am a little confused as to how it mounts. Does your lathe have a compound slide on it, and does the grinder bolt to it or to the cross slide? If you have a compound, you can swing it to...

Yes, 0.1% is a large amount for some poisons, and negligible for others. And in the case of most electronics, 1000 ppm is probably acceptable, as I doubt Mark will be using his controller as a hot beverage container anytime soon. But as a complementary example, the USDOT haz-mat limit for...

Finger clock = DTI. Got it! Never heard that one before. James

Ok, I have never heard of a "finger clock". Can you explain a little, please? James

Bentwings, you are absolutely correct, there is zero way to completely idiot proof something.... (had to go fix bentwings, my phone autoincorrected it to "beatings"). I had a similar experience with punch press guards in a particular department. We would design guards, fab them up, install...

Ken, That is a great example of Poka-Yoke. Designing something so that you can't assemble it wrong is something most designers should but often don't consider. Another option would be to make the castellations or other features such that it obviously doesn't go together right when you put it...

Do yourself a favor, before you start building. Throw away those cheap taps and dies! And maybe drills too. Buy new (sharp) high quality stuff, in the sizes you are going to need. Those (little) taps will be delicate enough already, you don't need to make your life harder. Getting broken...
