MACHINE SHOP TIPS #1 Taps tubalcain

[dennisou812]

if you want to know the drill size of a tap simply take the od of the tap minus the pitch in exampl 1/2 -13 in tap. half inch is the major od of the tap minus pitch is number 7 drill. To figure the pitch 1 divided by 13 =.0769 -.500=.423 with is pretty much 21/32 it even works with metric and is real easy

Greetings Tulbalcain. Just subscribed and I'm looking forward to picking up some tips and tricks.

That's a very unusal name Tubalcain, might you be a traveling man?

Wonderful educational videos. I have seen every one more than once, Please do something on the care and use of slitting saws. Thanks,JL

could put them into Spanish translation

Great video(s)! I'm working my way through them now. I agree on the 'finger type' extractors. Usually when someone breaks a tap, it's because too much torque was applied (chips built up, dull tap, hole too small from worn out drill, etc). If the body of the tap wasn't strong enough to turn it, those tiny little fingers ain't gonna do it either!

yeah its a shame that in todays world you just need a peon to do machining. shops i've been in have 1 guy who knows whats going on and the rest are illegals taught how to start and stop a cnc, if it needs to be stopped. no skill involved with a lot of the new equipment. but that goes with todays kids where every thing is just a key stroke.

Thanks a lot for these videos. I wish I could take classes for machine shop but everything is CNC these days.

[bunberrier]

LOL @ 6:37 That's why I'm sitting up straight and taking notes.

[dokot09]

lol i got 1 better i got a pipe tap thats 3`` from my uncle art

[wickedmongoose]

I'm an electrical engineer, but I love to learn a little bit about everything. Your videos have been invaluable. Keep up the great work.

[altpersona]

thanks for the videos.

You said they're clueless about these things at the hardware shop because all the old machinists are dead. Now don't be so negative, some of them might still be just retired or simply laid off. And thanks for yet another great video. I'm studying metal working and it's nice to know about the ways of the old school. Seems it's all about 5 axis high speed gazillion ipm cnc machining with a carbide cermet titanium bits, but your lessons might come up handy when a single part must be done yesterday.

You missed an "n" in the description. :)

Good that you're back.

If you really don't want to throw the work away there's a DIY EDM setup that might be some use. DC welding machine provides power. Some kind of commutator allows rotation. Cutting electrode need be little more than a nail that is angled so it traces a circle just under the root diameter of the thread, when rotated. Flood the hole with fluid (distilled water?) advance slowly, and keep clearing the hole of swarf. Then pick out what remains of the tap in the thread.

As an addenam to the other good comments, your time and effort are also appreceated here in the UK. I guess the USA is much the same as here, getting training on manual lathes is a thing of the past. Many years ago evening classes were abundant but now do not exist. Your videos are vital in keeping our hobby (Model Engineering) going. Thanks Pete.

i would have to say that a tap extractor has saved me more than onec at work. or you can drill out them with carbid drill. at work i do get the plesher of bean able to not removing a broken tap

[fatboyfester]

Summer vacation is over and back to shop class :) another great video looking forward to your next one .

[hooligan1717]

I really enjoy your videos, sir. You do a wonderful job of explaining the tasks we watch you perform. As a tool-and-die maker with more than a quarter century in the trade, I can appreciate the detail you put into your videos and the time you take to deal with small details that are easy to overlook but help to make the topic more easily understood for someone starting out in machining. You are helping to keep the "old ways" alive! Well done.

[catman72]

thanks for filming this, you make things fall into place

in my so many holes of knowledge :-)

[nemocheerio]

I would also like to chime in and say how much I appreciate you recording all of these videos. I am just learning machining, never went to a school that had a machine shop, and because of work now, I do not have time to take a class at the local college. Your videos are invaluable to me and I am so glad that some one is here to bridge the gap between the real oldschool knowledge and the "hi-tech" and use a medium such as Youtube to pass on the things that really matter. Thanks.

Good stuff Sir. I've always enjoyed your knowledgeable videos. Thanks again for taking the time to post this stuff!

[submarineboat]

Really do appreciate you sharing your knowledge. Thank you!

[sandwon]

Thank you for sharing your Knowledge.

I'm taking a Machine tool class.

You have helped me Alot.

[StMichaelsCrew]

Pete thanks so much again can't wait for the rest of the series on tapping. I've said this in the past I'll say it again. Your video's are priceless to me and I'm sure alot of other metal working hobbyist's, in the u-tube community. Your a hell of an asset to all of us. Thank you again Sir.

[JohnLoganMcKee03]

Great tips.

[americancolt]

i enjoy your videos, im a machinist and i've been doing this for about 5 years. I'm mostly a lathe man and i know quite a bit but its still nice to get some more info from the old schoolers. Also you can get a broken tap out of a hole, i did it with a broken 6-32 roll tap. I just has to use a lathe with a z working live tool. Used a small end mill and saved a part.

[russtuff]

the number of tools you have blows my mind.

thanks for sharing!

[therockkkkher]

your vids are the greatest !!! i wish america was still as good as when we had real jobs and real men like you !!! take er eazy buddy !!!

[fms6966]
