From what I remember about watching machinists using a shaper is to put the fixed jaw of the vice to take the majority of the pressure of the cut. It is better for the vice.
I really enjoy your videos. Much respect for making that lead screw and utilizing the follower rest. Do the burrs from chasing threads mess up the follower rest contact points?
Thank you so much! The chips can mess up the contact points, but they are made of softer material and are disposable. Or should I say consumable. And thank you again....
LOL! Above 50,000 feet, pilots are required to wear a space suit. The entire suit is pressurized. That's because if the plane depressurizes, the pilot will die without a space suit. When you see an astronaut carrying the little suitcase as they board the craft, it is their environmental control system. When they board the craft, they can tie into the onboard systems. Yea they went to the moon, LOL. And thank you very much....
@@jster1963 I just discovered a channel where the host models a scale airliner in Fusion 360, creates all the parts and assembles it. He covers every step in detail, including the modeling.
Smoking sure isn’t healthy. But certainly made finding pressurization leaks on airliner’s much easier back in the day. The nicotine staining was hard to miss🤣 GreatVid. Cheers for YYZ 👍
So true! When I first started flying for the airlines in 1992, smoking was still allowed on international flights. It was very easy to see those nicotine stains at the outflow valves and any other leaks. I would see that on my walk arounds. Crazy! Stay warm up there and thank you very much.....
Normally when redoing lead screws. You do the nuts and bushes as well. This way it’s all a match, and you get uniform wear across all of your parts. That’s just the way I’ve always done it.
You are 100% correct! I was just being lazy. Since it seemed to fit the nut in the vice, I decided to just keep it. I do realize that it will not fit another machine. I don't plan on selling it and if I need to repair it, I've gotten really good a picking up the threads. The video was 20 minutes, but this was weeks of setbacks. I just wanted to finish. Once again, you're right and I was lazy, LOL. And thank you very much...
@@jster1963 no dude I was not criticizing you. I was merely pointing out that was one way to do it. If it was for a customer you would do it the way I said. If it’s for yourself then you do you. I can’t tell you how many times my short cuts turned into insanity. Like removing a gibb and seeing gouges in it. Then thinking I could just polish that right out. One to end up buying new one three days later.
@@McFingal I NEVER thought you were criticizing me! It's just something I forgot to explain in the video. I try to remember to tell what I'm thinking and why I do something non-standard. Unfortunately, I just forget things now days, LOL. And great info! Thanks again.....
WOW!! As pilots we jokingly say that it would be a great way to die, because you would never know it happened. First heart attack? Well, I hope you don't have anymore. And thank you very much....
I've totally forgotten those numbers, but in a fighter if you don't fix the problem within that time, you're dead! And if you remember Payne Stewart's crash in 1999, both pilots went out. It's a fix it at the first symptoms and descend the plane immediately to 10,000 feet or lower issue. Luckily, I have never lost pressurization.
@@jster1963 I have been the observer on flight tests of large business jets and also airliners, where a cable leak rate check has been perfromed. In one, there was a rapid rise in cabin alt, due to software not closing a galley chiller outlet. At least on an airliner, you have such a large volume of compressed air, a small leak has no immediate effect. The fighters Px must be gone in no time.
@@RotarySMP So true! A rapid decompression in an airliner would take a BIG hole. In a fighter....not so much;-) Airliners are pressurized for comfort and the cabin altitude usually doesn't get over 8000 ft. In a fighter it is on a combat pressurization schedule. When I'm at FL350 in a fighter, the cabin altitude is FL250. That's why we wear a mask ALL the time. Not like Top Gun when they only wear their masks when they dogfight, LOL. The combat pressurization schedule is so that we don't explode(pressure wise) if we get hit with a round...
I'm back, got a problem how much O2 is in a cuft at sea level compaired to 10k, 20k 30k, As one goes up the pressuer is les and the air expands beyound the cuft, less O2 @ cuft the higher one goes, So if one says the O2 amount is the same @cuft at sea level, as compaired to 20ft, sorry I don't think so
The Air Force could be wrong about the O2, but I'm going to stick with what they taught us. And it seems to ring of truth because we don't pump O2 into the plane at altitude. We take outside air and pressurize it. But thank you....
The percentage of gases in air at sea level is the same percentage as at any altitude. The mix does not change, the pressure exerted by the gases is less the higher you go because the air(the combination of gases) is less dense the higher you go.
