Thanks for posting your videos. Having "tapping" for 40 years now, it's nice to hear your tips. They are great. I appreciate the basic instructions - never too old to learn.
I am a new student attending a welding and metal fab program at a community college in LA, Ca. I happened upon your videos, here on youtube, by way of a general "metalworking" search and I just wanted to say I enjoy your demo and explanation very much. I look forward to watching more and referring back to them often.
In your demo did you pre tap the holes before the video? Then re-tap in pre-threaded holes? I've never seen tapping of any kind that fluid or easy. Turning the tap more than a few degrees at a time would result in a broken tap for sure.
Whoops! I didn't realize I was watching part 3 of an infinite series. I went back and watched some of the other vids and you answered my question. HSS it is! I should have known you'd be so thorough. Thanks for all your tips. I like learning from you old-timers (no offense, age = wisdom). Your vids are making me get dangerously close to dusting off my 90 year old 9" south bend junior and ordering up a steam engine casting kit.
Thanks for the videos, love 'em! Very informative. I've been thinking of buying a large tap & die set. Is it worth shelling out the big bucks for a name brand set, or would a cheapo set from harbor freight work just as well? Also, what's the best type, carbide, high speed steel, etc.?
Thanks for the great videos. Can you provide any more information on the cup-tipped spring device? I can't seem to track one down in the catalogues. Thanks
While the steam engines and tractors are OK, I really appreciate the tutorials on machine shop work. Yes there are plenty of books, but watching a few high quality instructional videos really levels down the learning curve.
Could you please cover threading dies, including round dies and hex shaped dies? I assume the adjustment on round dies are so you can make two passes on harder material and the hex dies are more for thread chasing than anything else, though I have cut threads with them too.
Have you ever mixed up a tapping fluid? Like lard or kerosene?
@mrpete222 So, it's a different kind of tap and that's why the chips don't need to be cleared when power tapping? Not to ask yet another stupid question but why can't we use a power tap for hand tapping so we don't have to clear the chips? Sorry, I'm sure these are real "newbie" questions but...
@tzkelley Also hand taps aren't designed to take such a work load, when tapping by hand you can feel any rough spots irregularities etc when hand. Machine taps, turbo taps, Are always made out of a high grade high speed steel. This doesn't mean they won't break. So far the the only machine taps Ive seen are seen are plug taps for the drill press. Ive only seen just a bottoming tap used in CNC machines for starting a tapped hole and finished in one job using just this one tap. Take care.
Nice work, time and time again you have shown very concise and clear machining skills. Its an honour watching you work, im always scouring youtube for your latest videos. Ive gone through everyone of your videos on my days off from work, I can say your videos are the best, and look forward to any new videos you post.
Another great video Tubalcain... The moment you mentioned not locking the tail stock when threading under power, a light bulb went off above my head. Although I hadn't sought info on power threading on the lathe, I couldn't visualise how it might be done either. I am going to make myself a spring loaded tapping assist tool when I next get a chance. Many thanks for this series.
Terrific Training videos! A few of us at work talked about ideas we hope you'd consider featuring in future Tips & Tricks. How about 1) Dovetail cutting on the lathe or mill; 2) Fly cutting on the mill, particularly how to grind the right tool angles for a fly cutter - are they different for Fe vs non-Fe material?; 3) Milling on the lathe with a verticle milling attachment. Thanks again for all your dedication and terrific willingness to share your experience!
@mygomez100 Fly cutter angles are the same as a lathes angles on a facing tool. This came from Tubalcain when I asked him myself. I forget thou if he said it was to have the point broken with a slight radius, I did and found it to be a better cutter.
Your videos are great. I've learned so much. I'd like to see some 4 jaw lathe work as well as some with a faceplate. BTW our lathes are very similar mine is a Clausing 6913. I look forward to your next video. Take Care & God Bless.
I hate tapping aluminum!!! I did a heatsink the other day and the threads always look half stripped even though the process felt good. Though i used a 2.5mm drill bit for an M3 hole, which is due to experience with taps breaking with the proper size hole.
@TheElectricnoob hey bro, if you were trying to get a 3mm hole, you should have used a 1.5mm drill, you should always use a 2mm drill smaller than your actual thread you are trying to go for.
WOOHOO...I spotted the left-hand thread...do I get a prize?
What impact do your videos have?... well, here's one. I now have the knowledge to enable me to make a 'steel snake' hollowing rig for woodturning which is going to open up a whole new world of turning for me. Thank you for passing on some of your knowledge, a lot of what you do seems really basic to you but, for people like me who never were in a machine shop at school (regrettably now), it's pure gold.

I know that in woodworking they mark the depth on the drill bit with a piece of tape. I hope this helps to save a tap.

Why is it okay to power-thread but when hand tapping we have to back out every couple of turns?
