Man, I love going back through all of Tom's old videos.

Tom, In a word, Groovy! Thanks for show'en us your stuff. All the best Chuck

You are now a part of the power of the internet Tom - you have contributed quite a lot of knowledge that has been invaluable. Thanks for another great video

Wow! That's a slick design, thanks for sharing that with us Tom.

I know this is a very old video. But I always gain a wealth of knowledge from your sharing and effort Tom. It is always greatly appreciated. Looking forward to the next one. Stay healthy and safe my master!

Thanks Tom! I enjoy your videos! This one is helpful as it at least shows me what a boring & facing head can do and what the general way they work. I don't have a Chandler, but I recently bought an Enco Automatic Boring Facing head, made in France. So this video shows me in general what to expect. Now I just have to learn exactly how to use the Enco. *_I can see now they are very useful !!_*

Fantastic tool! Gotta put that one on my "Shop needs" tool list! Thanks for showing this, Tom! ;)

Hi Tom ! That's really a nice and nifty little tool ... and probably not a cheap one ! Thx for showing !

That tool is awesome. Brilliant. A serious time saver if you do a lot of boring. Minimizing boredom.

Thanks Tom. In my opinion, that is a really classy looking tool. I'll be doing some homework on it. Cheers, Tim NZ

D'Andrea (Italian) produces the best boring heads on earth - manual or electronic. Nobody beats them. D'Andrea has done boring heads for more than a 100 years if I remember correctly. I used many of their boring heads when I was still working and believe me, I tested the accuracy of their heads - brilliant! The one head I had was a 2 micron (on diameter) which I used quite a lot. Man, absolutely super.

Hey, Tom. That is an awesome tool you got there.I would to have one to fit my Sherline mill . Quite the mood music in the background. Thanks so much for vids!!!

What a nifty little tool, never thought about it before but a perfect way to cut retaining groove in an awkward shaped piece.

that was a very interesting episode:) thanks! greetings from Sofia, Bulgaria. Ivan

Thanks for the show and tell Tom, great little tool.

Hey Tom, If you haven’t already, you have to get your hands on a WOHLHAUPTER UPA series boring head. The tool nut that you are, you will fall in love. They are super German quality, very smooth, precision and beautiful lines appealing to the eyes. I have several Criterion heads a couple of them extra precision you can dial in tenths. In comparison when I hold them or turn the dials the Criterions fell like 1-2-3 blocks and the WOHLHAUPTER UPA-3 feels like a Jo block. I took mine apart once just to check it out. Insane design, I forget most of it but I remember it was very complicated, many pieces but beautiful. You can face and rapid return without changing rotation. Adjustable stops, lots of features. Joe

Thanks Tommy boy! I traded a gentleman on cl for one of these, mine is a bit bigger and on a 50 taper. Seeing a video on it is much nicer than reading an instruction sheet. Thanks!

Hi Tom, I'm sure you have better things to do than answering an old video question but your the only one with knowledge on this particular boring head. I too have one of these but it sits on an upper shelf in a box. its been 5 years or more in that box with-out using it. Many years ago I mistakenly used it in a drill press 25RPM or so and the darn thing chattered and fell out of the MT2. No damage but enough to warrant to put it away until I find a way to change the shank to something else other than MT2 with a tang. I'm not sure if it is screwed in or what, I don't want to break such a fine tool. I very much enjoyed this video. I don't mine watching re-runs "lol" you learn more and more every time! Thanks for the videos Richard

Hi Tom, I have a Japanese copy of a small Wholhoupter that I think I showed a while back. The bigger Wholhoupters have a series of pins you push in to set the feed per rev. One capability that you missed is that in combination with quill feed it's possible to machine a taper. Not that useful on a Bridgeport style machine with its limited feed rates, but it can be very useful on a horizontal machine. A friend has used it to cut taperlock hubs.

I have a bit of a boring-head fetish, so as well as a couple of Wohlhaupters I also have a Tree boring head. That has the unique feature that it will auto-feed at any angle, so can be used to bore, face or cut tapers.

I just purchase a Chandler Duplex boring and facing head (model D) off EBay. All the machinist websites I've searched have reference to the manual on Scribd.com but Scribd no longer has the manual available. Do you know where I can find a copy? Thanks!

I have the same model boring head with an r8 shank. Unfortunately the boring head cost more than the mill, but it’s a fine instrument. If you back out the thumb-screw in the dial face on the side, you can use an Allen wrench on the opposite side to return the slide, without undue wear to the gearing. As stated by the set of instructions I found for mine. It’s also much faster. Just be careful to get the screw set back in one of the index holes, I think there are six. Mine chatters like hell unless I lock the slide while boring a hole.

Hi. Is it possible to buy this particular head or a similar one but different size? My client is really impressed and we are willing to import it. Please let me know.

I want one of these! As a hobbyist they are insanely expensive from what I found.

Tom, Maybe slow down the spindle RPM to lessen the "fuzz" from the facing function. I think the AL may be getting a bit too hot at the point of the tool. That is one VERY cool item. Thanks for sharing! Eric

I purchased this exact model on ebay this last summer. It had a straight 1/2" shank and when spinning, it looks like it was crooked. I took it all apart and mated it to an R8 shank that I machined out of a regular boring head shank that I bought for maybe $13. I did not get the two "tool holder extensions" however, those two shaft like items with a square end on each. I would very much like to see a video looking at those in details so I could machine those too. For example, is the square part integral to the round part? Also, there must be some kind of keyway like groove on at least one of them right? By the way, the shank is screwed in with 1/2"-20 thread. Any information you could provide on my two missing pieces would be greatly appreciated. Thanks for the video, it was very useful to me.

Hi Tom. I've been watching your videos for a little while now and I currently bought your book. Love all the work you do for us viewers. I recently just acquired a mill/drill (Grizzly G1006) for the great price of free! I have no prior mill experience at all and I am trying to self teach myself. I have 3 questions for you that might help me. 1) I don't like the chuck that came on it and I want to get a high quality jacobs chuck. I want your recommendation on whether I should get a keyless or a keyed chuck. 2) In your book, you show that you made counterbores out of twist drills. I was hoping you might be able to go into detail about that or make a short video showing your technique. 3) Could you put together a short video or maybe some simple projects that would teach someone like me the general things I need to know about the mill. Maybe just show some tips and tricks. I understand a lot of your viewers are experienced machinist, and you go into some pretty complex things in your videos. Hoping you could make a video or start a series of videos for the newbies like me. Thanks Tom for all the great videos and keep up the good work. Best Regards, Michael

@oxtoolco

Hi Michael, Thanks for the nice comment. For your drill chuck I would get a good quality keyed Jacobs chuck. If you don't want to to spend the big dollars on a high quality keyless then your asking for disappointment. The Jacobs keyed is reliable and robust. The counterbores are not something you can easily hand grind. Once you master grinding a good drill point then a flat bottom drill then you can expand into making a counterbore out of a drill. On the videos on the basics there are dozens of really great videos already out there. I don't like to duplicate unless there is something really meaningful to add to the conversation. I try to focus on my projects and the operations related to those activities. Between all the pro's doing machine work videos on YT you should find more than enough to keep yourself occupied in the shop for something like the next twenty years. All the best, Tom

Where can i found one like that plz ?

Very interesting tool Tom! An observation... the threads that control the tool movement must be very fine indeed. It takes a number of turns to move the cutter the slightest amount. Also, how would you make an internal snap ring groove if you did not have a tool like this one? Would you use a standard boring head? Thanks for a great segment! Fred

Beautiful crafted German tool. Evn though Im a CNC guy and out dated for my setup there beautiful fine crafted well oiled little machines. I purchased it with a busted rack . Its mates is a worm gear Ive been reading for at least 3 months on gearing mates worms . Video after video . Still cant figure out the proper way to machine a rack with a helix almost to match the D.P. of the worm it mates to. If you know a thing about gears and there mates please drop me a line . That would be a good meat loaf though something not many touch on, Making gears , hobbing involute cutters and button cutters. Mark

@oxtoolco

Hey Mark, A rack that mates with a worm is similar to a worm gear stretched out flat. When you cut the worm gear you have to gash the teeth at the correct helix angle prior to hobbing the gear with a helical hob. This would be the same angle you would use to cut the teeth of the rack. This is a slight simplification but basically the direction you want. There is a great section on milling spiral racks in the book "A treatise on milling and milling machines" by the Cincinnati milling machine co. Cheers, Tom

Hey Steve, Were going to make him shop till he drops. He will never get anything done again. Cheers, Tom

Just adding a note here as someone that uses a boring/facing head, your spindle speeds are WAY too high in this video. For snap ring groove cutting you are usually at the 100rpm mark, for facing more like 250.

Why is it that watching someone do something on youtube can seem way more dangerous than when doing it yourself. Like I have hundreds if not thousands of hours on the table saw and while still have a healthy respect for them, I am confident in what I am doing. But watching almost anyone use a table saw on youtube, even in very safe ways is terrifying to me.

Thanks Tommy boy! I traded a gentleman on cl for one of these, mine is a bit bigger and on a 50 taper. Seeing a video on it is much nicer than reading an instruction sheet. Thanks!
