A good tradesperson never blames their tools

technically speaking, you don't really need a drawbar for milling, threaded collet chucks work just fine, you just need them for tapered tooling

I was sitting on the throne - where as we all know we do our best thinking. Been thinking if I want to make a ER32 D1-3 chuck adaptor plate but now I have decided I am going MT4 drawbar. Thanks for the video. Subbed!

Hi . Great video lesson, timely, thank you. I just acquired an old Craftsman lathe, it has a milling attachment and I am just learning a whole bunch of stuff about milling. Especially about needing a draw bar and collets for holding tools etc. The lathe has a 3MT spindle, is it possible to make such a draw bar as yours if I obtain a 3MT collet chuck? Also, what size is the thread on the end of the collet chuck? I am hesitating of getting one because I don't want to get one just to not use it if it is wrong. What size dye did you use for cutting the threads?? Thanks again.

In a pinch, I've used plywood bits, bolted to the carriage as a traveling steady rest. Not elegant, but helpful for light work.

Actually that probably would be pretty effective - especially for small stuff.

May I ask about the correct way to remove a collet once its firmed into place with the draw bar? I'm having to hammer the end of the draw bar to get the (MT3) taper free. This must be imparting quite an impact to the bearing of the lathe, which can't be a good idea. Should it come free quite easily, or is it OK just to keep on hammering?

Very cool

Nice video. What is that goopy cutting 'fluid' that you are using?

Thanks Ian! It's bacon grease of all things. I find it works really well in the home shop. It's solid at room temperature and turns quickly to a liquid. If you don't eat a lot of bacon (I'm Canadian, can you tell?) lard works as well in a similar fashion. I like bacon grease or lard because it is non toxic, and I find smokes less than other oils. When I was turning the rod in this video the shop smelled like breakfast.

We do precision work on our Taiwanese machines all the time. Most our parts will measure within .005 and for our industry that is above standard by a considerable amount. We have made parts close to .0004 tolerance and frankly that’s overkill we’re not making aerospace parts. Now if folks are staying high precision that’s a different scope of machining, tooling and die, etc... I still think it’s possible given a solid setup and a lot of patience. Probably not profitable since you won’t get repeatability under those conditions. Precision versus high precision? Definitely a difference.

you must have a very very special lathe to get such a small taper in that long of a bar and its steel too. LOL

Is this similar to a drawn reciprocation dingle arm?

Sort of. I don't know it has enough reluctance flux for that though.

WTH are you using or lubricant, it looks like glue?

I've been listening to your podcast, so you guys know you have at least 1 listener.. :) What are you using as cutting lubricant in this video?

LOL, thanks for the support! The cutting lubricant is bacon grease! Great stuff - I've used it in my other videos as well!

Great video, Justin! Did you use your new software for this one? Also feel free to polish the boring head, that surface finish was experimental and I'm still undecided on it. :)

Yes I did use new software so I'm learning it as I go. The surface finish is fine Max. I kinda like it.

I thought there might be a bit of This Old Tony inspiration going on here.

I don't know what the problem is with your audio but I had everything turned to the max and could still barely hear you over the background music. Maybe a better microphone or no music or make sure that the stereo signal is correctly phased. But there is something wrong. RonW

I dont think it was boring at all :). Loved it. Thank's for sharing :)

Cool. Funny I should run into this video now. I just finished my first "real" machine project which included a mt3 end mill holder for the lathe and you guessed it... a draw bar lol. 👍🙂👍 Oh! And Happy New Year! 😀

Great video !!! Again, I'm very impressed with the results you're getting from your lathe & concrete base. Did you try to ink your taper bore to see how well it mates with the adapter ? "Dihydrogen monoxide"...I think the nomenclature would be " Oxygen dihydide". At any rate water has a respectable heat capacity (as fire fighters will agree), so it's handy stuff to have around. Thank you ! Len

Thanks so much. The concrete bench has really changed the lathe. I haven't blued the adapter as of yet, but it locks in pretty good with a slight push so I think the contact is decent on it. That's the thing about Morse tapers I don't like - too much force to get them out. I'm not a chemist so I could have made a mistake :).

I was just having a bit of fun with the terminology. For the chem folks out there...How about hydrogen hydroxide

I paid $200 for a entire collet closer. They’re so cheap making one with those oddball threads is time consuming. Nice to have the quick change features. You can buy the m1019 13.5x40 closers online for $150 for the entire kit. Don’t know if you have to shorten or lengthen the through bar. In my case the grizzly unit it had to be shortened and I chose to go from the back end and rethread the metric threaded end.

I do like your surface gauge - what brand is it?

Your voice seems pretty quiet in relation to the music. Otherwise, great video :)

Interesting video but ditch the music it's a distracting b depressing !

good video but the music is potted to high and caused a tremendous amount of ear fatigue. I hade to mute it and watch it with closed captioning.

Very interesting video spoilt by manic music,!!!

Look up yakshaving 😁

Enjoyed the video, Justin. Very well done. Regarding the precision of import lathes, it also appears to me that your lathe has an unusual bed configuration in which the vertical portion of the bed extends all the way down to the support surface along the entire length of the bed....as opposed to just about every other Chinese lathe that I have seen which have "feet". drive.google.com/file/d/0BzbPL0q377AoYmxBQUFXT3ZTZFk/view?usp=sharing The configuration of your bed would seem...at least intuitively... to aid in rigidity. A minor production note....around the 13 minute mark, I was having difficulty hearing your voice over the music.

Hi Hans, Thanks so much. The lathe is a bit of an odd duck, I haven't seen any similar models in the US by the large bear importer. It appears to be unique to the importer in Canada. I've also seen them in Australia, and New Zealand. It has an odd 7 tpi leadscrew which makes you think, but actually is quite useful once you get adjusted to it. The bed is large and is supported along the length - this is why I wanted a full piece of granite across the supports of the 'bench'.

Helpful video, but spoilt by distracting and unnecessary music.

Thanks Brian. Music is a really touchy subject with many. Some people like no music, others find that boring. I'm trying to strike a balance and trying to find some 'non invasive' stuff. Really appreciate the feedback though.

Very good video and info but I have to agree the music is very distracting.

Sorry, couldn't bare to watch because of annoying music. I would rather hear the sound of the equipment 😞

Music is bloody annoying, over powers the voice!
