Literally learned more from this video than anything else in my life on machining. Thanks for sharing.
Wow, what a gem! Thanks for sharing!!
60 or 70 yrs. later, and some of these machines are still being used. CNC has taken over with big Companies, but there is always the manual Lathe and Bridgeport off in the corner somewhere. Some small Shops in 2022 are still completely Manual.
I like the wooden tool box. I wonder if it's a Kennedy
Gerstner
yes in pakistan and india
That is actually the most haggard way to center drill something I have ever seen.
Holding the stock..LOL YIKES!
I guess haggard, HOWEVA.... how many planes from U.S plants flew in WWll and all the planes parts built with this method.... ain't no arguing that! Surprised you didn't attack the hand ground tool or, the tool post holder too! Sheesh millennials LOL
i am confused
was he holding it or supporting while centering with the center drill???
@@chrischapel9165 if a lot is coming off it doesn't really matter but why not stick it into the center chuck it like you normally would center it?? that's how they did it 100 years ago why was this guy doing it backwards
@@christophercolumbus8944 - the center drill will follow the center punch mark.
I'm amazed at how long it took before ball bearing live centers came into use, being as there were so many other bearing-supported components in these machines.
Dead centers are STILL the highest precision method. If it HAS to be right on, it has to be on a dead center. Live centers are for production work.
I have never seen center holes drilled that way. If you did that in a contemporary shop the osha guy would have a fit.
I learned it exactly this way in my vocational training in 1995.
Was this before "chuck" came along?
Anybody know what lathe this is? To me it looks like a southbend heavy 10 but I'm not sure
Looks like a 13 south bend
👍
FYI this is NOT how to do it; to do a center hole safely, you put the drill in the tailstock, and mount the job in the 3 or 4 jaw chuck, that way your arm isn't ripped off if the drill jams 🙂.
OR if you have to follow along, do the drilling of the center holes in a drill press first.
I think the diameter of this work is such that it would not fit through the chuck.
i'm so glad i have access to modern machines and cutting tools, this is just sillyness
they do not tell you any ways to make sure the centers are centered to each other Uncentered centers will create a taper More so on longer parts
The effect is bigger if the part is shorter. But u are right. With a centerdrill that have a radius instead of a taper, u can use this to produce extrem accurate cones.
Sure they did. It goes together with saying it's not as simple as it looks
and what happens when you have 100 of those shafts ?
+kiss peter Overtime!
Lmao Dale....very true!
You machine one at a time until 100 pieces are finished.
Published in Sept 2013 that wasn't WW2 buddy that was WW1 these machines were in use during both World wars. I am sure they were more Widely used during WW2.
why do we keep calling drawings blueprint they're not blue anymore
that's the most ridiculous way of drilling a centre hole ive ever seen
