I didn’t bother listening to the video. I scanned through it and got the drift. These kind of guys just prattle on and on and on, like everyone really wants to spend more than 10 minutes listening to their voice. It’s like those product reviews where they go on and on about the box; can you just open the darn thing up, stop talking and talking, move your hands out of the way so I can actually see what the product looks like and then clearly show me how it works.
It’s one thing if the author is conveying alot of very useful information within a short video (like Dave did on the Lelit Elizabeth), it’s another to drone on and not convey much substance.
Anyway I watched his extensive and long tamp nutation and tapping technique and it’s no wonder that his shots channel. If he has any time left to drink the coffee. Double tamping just causes double the trouble, though I suppose the puck is as compressed as it will get.
I just carefully and consistently WDT and then levelly tamp at the same pressure every time, using an EazyTamp. Others shake. You can pretty quickly tell if your distribution technique works or not, by watching the shot or checking the puck. But I perfected my technique a long time ago and the EazyTamp got rid of the tamping variable. CoffeeTime helped me sort out alot of things in a friendly (no question is too dumb to ask) environment.
YouTube seems to make authorities out of everyone. I feel for folks who are new to a task or hobby; how do you know what is actually the correct approach? I once watched a video on how to remove a scratch from a ski google using toothpaste, which is a real dumb idea. I tried it on an old pair of junk googles first and it scratched the heck out of them.
