    The hotter it gets, the thicker the oxide layer form

    This is accurate enough for tempering of most cutting tools, but technically, the oxide layer will continue to grow if you hold a lower temperature for a longer than normal time, and might not fully develop if you reach a higher temperature for a shorter than normal period of time.

    This property useful if you are trying to develop a specific color rather than achieve a specific metallurgy. You can heat to a lower temperature for a longer time to develop a deeper, more consistent color.

    In my experience, it’s easier to develop colors with an oven or propane torch rather than a forge or acetylene.





  • I won’t say that this blade is properly heat treated; it probably isn’t. In welding, the problem is the wide variation of heat affects in a very small zone. You can have material that is very brittle just millimeters away from material that is very soft and ductile.

    You’re describing “normalization”, which is a process that makes steel uniformly tough, but “plastic”. When you flex it, it bends, and stays bent. “Annealing” is a similar process, where the temperature is raised a bit higher, and the cooling slowed even more. “Annealing” leaves the steel very soft.

    In tool making, you’re first looking for high hardness (acquired with a “quenching” process). This makes it very brittle; it has no elasticity.

    Next, you’re dialing back that hardness with a “tempering” process, which is done at a lower temperature than the normalization process, and the cooling can be much faster. When tempered, it’s still very hard, (significantly harder than “normalized”) but now it is slightly elastic. It will flex, but beyond a critical point, it just snaps; it probably won’t take on a permanent bend.

    These colors are oxide layers that form at temperatures in the “tempering” range.






  • The 15% or 20% guidelines are based on the amount of work performed by the tipped employees (who earn less than minimum wage before tips.) the amount of the check correaponds pretty closely to how much time a waiter has to spend serving a table.

    Drivers are not usually employees; they usually have $0/hr in wages, and pay their own fuel and vehicle expenses. Delivery services typically pay $2 per trip, and a trip will involve 2-4 stops. The base pay from the delivery service does not even cover fuel costs, let alone the driver’s time.

    The amount of work a delivery driver performs is not at all related to the amount of the check. The 15%/20% rules are not remotely close to the amount of work the driver performs. $8 on a $20 order is a garbage tip if it’s a 10-mile delivery to a fourth-floor walkup. $4 on a $70 order might be a decent tip if it’s a 1-mile delivery to a front porch.

    The appropriate tip for delivery is based on mileage, not food price. $1 for pickup, $1 for dropoff, and $1 per mile is a pretty basic tip. A driver can complete about 3, $2 runs per hour. $3 tips gives him a gross income of about $15/hr, and he can net about $10-12 of that after expenses.









  • “Oh, you were misinformed about something worthy of a snopes article, have you considered that you might also be wrong in opposing murder?”

    Yes. That is my question. Is it possible that the same sources and methods by which you came to be misinformed about his mother have also caused you to be misinformed about the actual circumstances of the attack?

    12 jurors all heard the same evidence, and concluded that his use of force was justified against all three of the people he hit, and a fourth that he fired upon and missed. What do you know about the case that leads you to believe differently?

    Were you aware that there was a fourth person to attack Rittenhouse?

    Were you aware that Gaige Grosskreutz (“Byecep”) was live streaming, captured Rittenhouse stating he was going to police, observed him running toward police, and still called for mob violence against Rittenhouse?

    These are all from primary sources: people and video directly involved. They aren’t from reports or commentary. If any of this information is new to you, how confident are you that you now have all the relevant information? How confident should you be?


  • What type of source would you be willing to accept?

    I know that your claims do not arise from primary sources. No audio or video recordings from Kenosha show her to be present. No witnesses for either the prosecution or the defense ever testified to involvement that could be construed as proving your claims. I cite the trial transcripts in supporting mine.

    I will note that you have provided no source for your claims. I know they did not arise from any primary source, but I do not know what secondary source you are relying on. Are you willing to accept major news organizations, such as Associated Press? They reported that false claims of her involvement were widely reported in social media.

    Fact check.org also refuted claims of her involvement.

    Politifact concurred.

    Are you as certain of Rittenhouse’s culpability in the killing of Joseph Rosenbaum and Anthony Huber, and the wounding of Gaige Grosskreutz, as you are about your claims about Wendy Rittenhouse’s involvement?


  • The mother did not drive him to Kenosha, or across state lines, and she was not involved in acquiring the rifle.

    He drove himself to Kenosha. Dominic Black acquired the rifle. It’s unclear whether it was Dominic Black or Rittenhouse who drove him home, but his mother was not in the car. Hours later, his mother drove him to the police station in his home town - not in Kenosha, not in Wisconsin - where he finally surrendered himself.

    Frankly, it’s disgusting that even basic facts of this case are so poorly known. I am still seeing claims that Rosenbaum, Huber, and Grosskreutz were black.
