Making a cross drilling attachment for my vintage lathe

- My second attempt at making a cross drilling attachment for my vintage Karger lathe. I really need this to work so I can continue with the collet chuck backing plate video.
I am trying to make a little money for my youtube hobby, through the Banggood affiliates program. Follow the link below, buy something you NEED and I'll earn some commission. Doesn’t cost you anything extra, and you're basically saving money out of Banggood's hands :)

I enjoy a good 'state of the channel address' such as you give. The thing that makes a channel worth watching (at least to me), and the channels that I feel are most beloved is when/where people are simply themselves. You are the best and only person I have ever seen be you.. and I think it's working. So onward into the new year! :)
The state of the channel speech will be in may when I complete my 3rd year on the youtube.
I guess this was my new years address :) We'll see where this goes in 2019.
Keep on posting you inspire me to try things I have needed to do for years. I've had my little Atlas lathe for about 50 years and it has served me well. Now with the internet and especially all these YT channels I've gotten a little more educated on procedures. My Dad was a machinist for a large Oil Well tool company for 43 years and he taught me the basics, but times have really changed since then. I don't have much material to work with but I see now that it is possible to do some useful things with my scrap collection.
Making videos is also a good way to learn a few things. And it's a fun hobby.
Try to use Bronze , make Bronze bushing on both sides and that should solve you issue , with a little bigger tolerance . When it will be turning , will grow a little and will be tight . Bronze will keep it running . :)
I don't have any bronze. I've got plenty of brass but apparently that's no good.
But I'm planning to install some needle bearings. Those are small and will fit the same holder.
I enjoy the good attitude when things go wrong. Keep on trying and learning.
I think you should know, when I go through my list of videos to watch at the end of the day, I watch yours first.
That is good to know :) With a few more fanatical tool temple followers, I'm confident I'll get that mini mill this year :)
thats why i like my vintage lathe i use it as a lathe and as a mill
its from 1920 magdenburg
Keep on turning buddy. Lessons learned for all of us. Metal on metal tends to gall and any imperfections between like metals will cause ceasing. Try a softer metal for bushing or bearings. Problem solved. The other issue I notices what not going all the way through with your reamer. Can sometimes leave a slight taper if you don't go at least over the halfway point of the reamer on the way in and out.
I agree bronze bushings would be a good idea, you should add small oiler holes and oilers to keep the bronze or oilite bushings lubricated, good tools take time to make so take your time it looks something like a watchmakers drilling attachment with a small pulley on one end. Making the spindle from tool steel hardening and tempering it afterwards would probably me a good idea. I think your spindle housing is a good solid design you have a good tool in mind and I will certainly make one for myself one day , look forward to more videos Bravo!.

You have a great sarcastic sense of humor :)
its about time you made another video, I am getting tired of watching the same old ones over and over and over.
What's your favourite video? I'll make sure I'll load it up with all the ads that will fit :)
I don't know what you ordered for bearings. I do know that the time for delivery can be a huge problem for spontaneity. I have waited for months for many and forgot why I ordered...the project already dead or stored away in a half assed state (DIY electronics and such)
Wishing you the best for the coming year!
I've bought some cam shaft needle bearings from Banggood. They are tiny and will fit the same holder.
But you are right, it will take a lot of time before they get here, I might have moved on to other projects by then :)
I like DIY
I wonder if you would have had better success if you used the cross slide to advance the drill
this way, you could polish up the bar/holder and you would have a better chance at mating them.
a single bearing surface I think works better than a sliding surface, as you have far more torque etc to cause friction
polish the bar and the holder just where they mesh, and put stop collars on the bar so it can't move.
you'll use less oil for lube and retain the surface of the bearing area
rM,
No need to apologize when something doesn’t work out and in addition any effort, no matter the success or failure is only a “waist of time” if you fail to learn during the process. I enjoy your comments and videos. Happy New Year and much success to you!

You're right I did learn a few things, and I can still salvage the part by putting in some bearings.
I could hear the drills screaming, 'gimme a drink, dad!' ..... Or wait, maybe that was my 4 year old, or maybe both...
Really a big bummer on the cross drilling attachment. If you asked my opinion I'd recommend some bearing bronze (660 brass) sleeves/bushings in the clamped piece. Most seen to insist 'oilite' (SAE 841) in that circumstance, but it's lubricity is comparable to bearing bronze and cost so much more. Also seems a bush or sleeve would work alot better as galling is extremely easy when using similar metals and or steel aluminum. Just my opinion, take it or leave it.
Glad to hear the new year will be coming without much change, love your channel, projects, commentary and all that good stuff. Thanks for sharing with us mate!
I think it must be the material cause I used quite a bit of oil.
I've ordered some needle bearing and I'm hoping those will save the project.
But I probably need to make some sort of thrust bearing out of some yellow metal.
Hopefully brass will work because I don't think I have any bronze.
Best of luck in 2019....
Thanks, I can use some luck :)
You can just stop a reamer in the hole like that? It doesn't damage the cutting edges?
Sure, why not? Just don't run it in the reverse direction, like I did when I hooked up the old VFD.
ja ik heb er ook eentje gemaakt maar van binnen heb ik een soort pijpje van brons gemaakt en een olie ingang en zo draait hij beter tot kijk
Dat had ik ook moeten doen. Maar helaas geen brons. Maar mogelijk had een stukje gietijzer ook wel gewerkt. Ooit ga ik het opnieuw proberen :)
Another try and something learnt I hope. Mate I hope for your sake they turn up before you have another go but what I can’t understand is (unless you edited it out) how did the shaft expand so early, it only turned for 5 seconds, with oil I wouldn’t have expected the shaft to expand that quick. Thanks for your talk at the end your advertising dollar kicked in exactly as you said it, can you time it? All the best for 2019. Peter
Nothing was edited out It was over in a matter of seconds. Very surprising considering it was well oiled and not running at extremely high RPM. Electric drills don't go very fast at full speed.
Yes it's possible to exactly time the advertising slot. But a lot of the time google won't show an ad.
In the accent of the French y Jacque Cousteau sponge bob narrator as we watch the power hacksaw,” some days later...”
Enjoy your channel looking forward to a weekly update
Yeah, about that weekly update.....
Haha it’s all good I’m sure the video’s can be a pain in the ass . Good to see them when you can
Interesting to see you build this Drilling attachment for your lathe. Nice to share the new year thoughts about your channel. You just do good work and you will do fine people like these two California-USA desert dwellers enjoy good machining not sexy man in bikini, LOL. Happy New Year too you as well.
I forgot to mention the most important bit. Have some fun :) Thanks and H.N.Y.
Hello RM. I have looked at your Pictures and enjoyed them. I left Likes. And Has always with your videos I Liked,Shared and added to Playlists. If you can find an old Hydraulic Cylinder with a chrome ram / shaft. that may help but may be a job to turn on the lathe. Keep the videos coming, has many as you can. I like them all.
All my best.

Hi Bobby, I notice you joined my google photo's album :)
At 3:38 you insert a mk(2 I guess) conus - is that an original feature?
morse taper ;-) - this is what I meant
If it's that cold, spend a weekend putting in a gas heater and some insulation. Waaaaaaay cheaper than the hospital bill for missing fingers.
Actually I wasn't that cold last weekend.
I wear the gloves because I noticed that my white hands mess with the auto white balance of the camera :)
You mentioned it was a pity you cant enlarge the pictures on the community tab post, I thought I would mention that if you right click on the image and select 'open in new tab' it will open a larger version of the image in a new browser tab, if you then click on the image in that tab it will zoom all the way up to the original image size.
Hope you find this useful ....
You must be using another browser then me. (firefox)
But I suspect it is just up-scaling the same low resolution you see on the community tap.
@@Rolingmetal Sorry, you are right, I use chrome, however I used firefox for many years (you should try chrome atm I find it much better).. so I tried in firefox and there it is, right mouse and then 'view image' gives the same result.
Interestingly I was not able to view your home page in firefox the same way I do in chrome and couldn't find the link to the community page, so had to copy and paste it.
Re the up scaling, I don't think so, you can see the added detail and it enlarges it bigger than screen size when I click on it.
Andrrew
I won't be using chrome. It sends to much info to google.
Can you right click the image and check the resolution. On my computer it's always 640x360 but it might be different on a computer with a 16:9/10 aspect-ration. I still use 4:3
@@Rolingmetal You can turn all that off, but I am not a Google salesman :) .. anyway.. the images are 1600 x 901, but when you right click and download image it always downloads the full resolution image.
but it is definitely showing the full image after clicking view image and then clicking on it, is this not working for you ?
I've checked on my work computer that has a 24" 16:10 screen. It also displays 1600x901 images. That is still pretty far of the original image size but a lot better then 640x360. I guess at some point I have to start thinking about a upgrade.
Safety Nazis - hey, if you had to work in sub zero temperatures, you'd wear gloves too. They're my fingers to lose if I were stupid enough to put my hands near any spinning parts, and I'm pretty sure those gloves would rip before fingers. I know, I use them, and they don't hold up worth a damn.
I wonder if people think it's safe to work with a complete loss of dexterity due to the cold.
Besides that, a lathe isn't a bench grinder. If you're incautiously putting your hands close enough to be caught by anything, you're already doing something wrong.
If you're not willing to accept that remote risk, you might want to consider removing the rest of your clothes as well. Surely that will eliminate all possibility of injury. Better safe than sorry; after all, you can't be hurt by something that's not mentioned in the shop safety rules you had to memorize in high school.
Lots of people preoccupied with other peoples safety these days.
Must be all those health and safety people taking their work home :)
I kind of like the high pitched squeel . Lol
Yeah, it's pretty bad and sounds even worse on camera.
Have you considered oilite bushings?
Not really. Is it possible to machine those oil impregnated bearings?
@@Rolingmetal I have in the past. But they come in such a variety of sizes, there's usually one that's close to what you need. Perhaps just a shave to make it a press fit into your tool 'body' and a slip fit for your drill shank. One front and rear. You should be able to get a nice finish, if you think about it as bronze with it's own cutting lube!
Why didn't you put in bronze bushings
I don't have any bronze. Of course I could have liberated that ugly statue on the town square :)
Bummer about the VFD and the latest attempt with the cross drilling attachment. Not really a surprise that aluminium - aluminium does not work well.
You mentioned ordering bearings but did not mention if ball bearing or sintered bronze. I think for this application sintered bronze would work well and be inexpensive. A link to illustrate.

I could not imagine trying to publish a video each week. I appreciate the effort in the editing never mind the work on the project.
Dave.
Another thing learned the hard way :)
I've ordered some cam shaft needle bearing form Banggood. Hopefully they will do the trick.
To be honest, I don't expect to keep up the one video a week schedule :)
Although back in 2017 I did make more than 60 videos.
I'm crazy enough to think I can build a milling machine . . . >.< I just need the right SCRAPTONIUM ! * anything is possible "V" ( Likeliness is an eventuality ) 'Still working on making a usable lathe ;p !
With the right scraptonium anything is possible. Go for it!
At some point I'll try to make my own wood lathe.
Thanks for not planning on major changes, and thanks for not appearing in yoga pants!
Sure thing :)
use a block of cast iron as a body of your attachment or make a simple brass bushings, it will be always fucking nothing the way you do it
It surprised me quickly it got stock. Lesson learned :)
I won’t say I told you so 😀
Oh and Thursdays is good for me
Ha ha
You should have told me before I started making that holder :)
@@Rolingmetal I did tell you :)
A standard rule for moving parts is use dissimilar metals. Anything more than a center punching jig will bind up.
I was actually surprised at how fast it bound up. I was secretly hoping it would work but deep down I new it would fail.
You will not forget that lesson :)
The speed of the lock-up surprised me as well. But I've ordered 2 small roller bearings and I think I should be able to save the project.
@@Rolingmetal Roller bearings should be great. I look forward to the fitting and testing.
A couple of plain bearings made from a bit of brass rod would have done the trick but roller bearings will be interesting :)
Cast Iron for a bearing material would have also been OK. Obviously bronze is great too.
One guy here was talking about modern lathe beds being steel on steel but in fact one of them is probably cast iron and the steel side is probably hardened.
The movement on lathe slides is probably measured in metres per day not metres per minutes as well. :)
Rolingmetal in a speedo. Aye Aye Aye. Not needed. Enjoy your videos as is!!!
No bikini? No yoga pants? What a let down! Oh well, there's always the chance Pierre won't be so prudish. Hopefully, you only fried the MOSFETs / SCRs in your speed controller and those should be pretty cheap to replace. Order a quieter fan while yer at it :)
I do have some tight cycling pants, complete with diaper, bet you would like to see those :)
Not sure what's wrong with the drive, electronic is not my thing. I've had it open and could not find any obvious damage.
It also does not have that burned electronics smell.
No smell could be a good thing. A full diaper can be nasty. As for the controller, the drivers can fail quietly. I'm assuming the lack of cooling was the issue so the parts needing cooling are the likely culprit. If you are adventurous, broke, or just a tightwad like me and have a test meter and a soldering iron I'm willing to help. Maybe do some troubleshooting via a video call or something. I keep a small box of replacement drivers because some days the Gods just don't like me. One week I had 4 controllers fry repeatedly. I must have replaced 20 parts and then the sun spots or whatever faded and no more trouble (so far).
25 FPS FeelsBadMan
Explain. I was pretty happy when I got 25 frames per second when playing BF2
@@Rolingmetal Well, others video's looks normal to me. IT was always 50-60 FPS i quees
You are very preceptive. The video I uploaded is only 15FPS!
The program I use defaults to 29.97FPS. I usually set it to 25FPS because my camera records 25FPS
Look like I made a mistake this time.
Well i made a big mistake
what is the fucking framerate on this video?????
gotta be 30 fps video
I accidentally encoded that one in 15 fps instead of 25 fps.
Not many people have noticed that. Re-uploading just takes too long.
No yoga pants? - I'm un-subscribing!
I've got some cycling pants. They are pretty tight and come with a build-in diaper :)
