Lathe Milling Attachment - South Bend Model A Lathe

[@fpreston9527]

Great videos from you. Clear instructions, good camera work, no fuss

[@davidchavez81]

Heads up, to convert to metric (millimeters) you just multiply your thousandths by 25.4. Works every time.

[@doktorfixit]

This a great video. But I want to congratulate you on one aspect which is RARELY seen in this type of tutorial. You can be EASILY heard (and understood). So many of these videos would probably be much more instructive if we could actually hear the narrator. Even some of the very popular KZbin machinists try to "talk over" a running mill or a lathe that is making so much noise we can barely hear the machinist's voice. I don't know if you have just voiced over a previously recorded video and turned down the background sound or what, but it is fantastic because we still get the sense that we are hearing a machine but it is not the only thing we are hearing. MANY THANKS.

[@BasementMachinist]

Thank You! I am not a fan of talking over machines either. It is kind of annoying and I don't plan on ever doing that. I do some work to the audio. Nothing major really, just remove background noise and equalize and normalize my voice to make it the same volume throughout the video. I not a big fan of voice dubbing either. I will only do that if for whatever reason I loose audio from a dead mic or too much background noise. Thank You for watching, I hope I can get back to making new videos soon.

I too have a SB 9 in lathe. I have been toying with the idea of buying a lathe milling attachment and have watched a few on You Tube, but I want to watch guys like yourself and see how they do it. Great job on your project. Look forward to more videos.....Ken from Marina CA .

[@BasementMachinist]

Kenneth Bartlett Thanks for the kind words. I too had watched many videos. Most all of them had a milling attachment that came with the lathe, or they spent the money on original equipment. That's all well and good, but I wanted to show an option for people like me who have to work around a budget.

[@358trucking]

Thank You for this video! This helped me greatly to figure out my best plan of attack! I bought this exact mill slide also and will need to modify it slightly. Can’t wait to use it. Great Video! 👍👍👍

[@shakdidagalimal]

Your parting tool is very smooth.

[@donaldnaymon3270]

Great job. Came out nice. Thank you for sharing.

[@KohalaIronWorksCase]

Cool. I been looking @ milling attachments for my South Bend Heavy 10, but I like the thought of having a table with T-slots.

[@shakdidagalimal]

I wanted to see the enco needle sweep through the broken crystal and grime area to see if it wailed some goober loose. I've got to say that certainly is working with what you have, with fine results.

[@RustyInventions-wz6ir]

Nice work

[@Evan-e-cent]

Very nice job! I suppose you could use the same method with a heavy L-shaped casting of any sort and mount the cross slide on it vertically. This might be an even cheaper solution. I might do that on my Boxford lathe.

[@bubbabubbs9244]

Sorry. I got kicked out of your page and didn't think what I had typed had even made it to the comments section. Anyway, my reason for being here is to ask your opinion about a milling attachment. I noticed while shopping for the attachment you recommended, that they also have a swivel base model. Are you familiar with this attachment and do you think it will be stable or rigid enough to turn out, at least, a semi-quality product? I was a machinist 30 years ago, in the military, and I can tell from watching your videos that you know what your talking about. Your opinion is pretty much going to determine which direction I go with this. It's been a long time since I've even laid hands on a lathe, so rusty doesn't even begin to describe where I am at this point. Watching your videos and implementing some of your suggestions helped tremendously in getting me back in the saddle (I did it again. Another lathe reference) and interested in One of the few jobs I've actually liked and took great pride in. Creating something from nothing, to me, is one of the most rewarding things a person can do. So for helping to peak my interest and also helping to Kickstart some long, lost, dormant brian cells in this old noggin, I thank you. I also thank you for taking the time to make these videos and for sharing your knowledge and experience with this old has been and also the up and comers. Your opinion matters to me, so if you're still out there and responding to these things, I would appreciate your input on this matter. The old, retired, once, long ago machinist. TOROLAM for short. The military loves acronyms.

[@franklancaster3576]

Nice job...may I ask what vise you are using?

[@scottcahill8690]

What do you use for drill bits?

[@dogbreath312]

I realize you called out most if not all the measurements but by any chance you have a drawing of this adapter?

[@philhalleck7201]

I have the slide and have made the hold down piece to match the SB cross slide (although I'm using 1/2-20 thread). I do have a question though...What did you end up using for a vise or hold down? None of my vices will fit on the ATOZ table.

[@ypaulbrown]

Wonderful

[@hpbear101]

Any update on how you like that milling attachment? I made the cross slide stud as you described so I am ready to order a milling attachment and curious if it has worked for you. TIA Tom P.S. Thanks for the vid's they are very helpful to this beginner!

[@BasementMachinist]

It is working very well. I just finished building a small steam engine using it. It does have limitations. You can't hog out large amounts of material, and the setup isn't rigged enough for climb milling. It will produce good results so long as you don't try and push it too hard.

[@hpbear101]

Thank you, I will get it ordered.

[@BasementMachinist]

I forgot to mention. When using the milling attachment tighten up the gibs a little on the cross slide to give you a bit more rigidity, and always lock the carriage.

[@hpbear101]

Thanks again.

[@johnkenure4188]

its metric each rotation is 2mm

[@darrenjames9422]

Thanks for this informative movie! South Bend 10K newbie, the first thing you find you need when you buy a lathe- is a milling machine! I just ordered the Myford slide, what are you using for a vice?

[@robappleby583]

Looks like the slide is measuring 2 mm per turn with an error of around 0.05 mm which is 2 thou. OK, I see other people have made the same point.

[@bubbabubbs9244]

Hey HB. Are you still milling about out there in youtube land? If so I have a question I was hoping you could help me out with. I recently purchased a SB 7A and whilst perusing the internet for info, tips, tricks, etc. I came across your videos. 👍Most excellent ,I must say

[@onenewworldmonkey]

I can't believe no one sells that swivel you made.

[@Hunter271828]

Quick question, at 6:40 how did you decide to use a 60deg form tool? Could you also set the compound angle to 60deg and use a standard tool? I just got my lathe moved in this weekend: hunterlong.home.blog/2019/01/28/lathe-moving/ Thanks!

[@BasementMachinist]

60 degrees is the angle of the "stud" on the bottom of the compound. The cross slide has two pins that have a matching angle. When you tighten the retaining screws the angles pull the compound down onto the cross slide giving it more rigidity. Yes, you can set the compound to the correct angle and use a standard tool.

[@S19D4H8]

76.5 thousandths of movement for one rotation of the graduation dial on the vertical mill slide equals 3/32 of an inch.

[@BasementMachinist]

Not quite. 3/32 is about 94 thousandths.

[@antigen4]

76,5 thousands of an inch is approximately 2 mm

[@k9c7a5j3]

Where did you buy the Miford slide?

[@BasementMachinist]

I bought it from ebay. It was shipped from India. www.ebay.com/itm/Atoz-Lathe-Vertical-Milling-Slide-Attachment-Fixed-Base-Myford-7-Series-Suitable-/262699617663?hash=item3d2a1e0d7f:g:SnkAAOSw4GVYF5Sv

[@Hunter271828]

Great video! I just purchased an old South Bend 10k, my first metal working machine, and this looks like the easiest and cheapest way for me to do some basic milling! I know everyone says just buy a milling machine, but I live in a townhouse and barely have room for the lathe. I know that this website sells milling attachments: www.statecollegecentral.com/metallathe/index.html, but this looks easier for a beginner.

[@bearup1612]

If you have a digital caliper it should do mm and inch

[@georgespangler1517]

Seems southbend has a lot of good over atlas but milling attachments not one of them

[@ussweeneyd]

Sorry but, did you say you have no way of accurately measuring metric ?

[@BillyTpower]

Could I please ask you a favor? Assuming you agree here it is...lol Can you please measure that table dovel width dimensions for me please? I want to see it will fit the male dovetail on my cross slide.

[@BasementMachinist]

+Billy T I sure can. I'll get those measurements tonight.

[@BasementMachinist]

I don't have a set of dowel pins or a micrometer big enough to get an accurate measurements of the dovetails, so these are rough measurements using a steel rule. The root of the female dovetail, without the gib, is 1-15/16". The narrow portion, without the gib, is 1-19/32". Hope this helps, let me know if you have any other questions.

[@BillyTpower]

thankyou, this will be very useful info

[@rickdenney5772]

0.0765 is 13 tpi. 1.000/13=0.0769. Are you guys sure the screw isn’t a 1/2-13 threaded rod? I never know when those guys use metric or imperial tooling to make whatever they are making. Yeah I know I’m five years too late 😊

[@100nortonfan7]

Anyone interested in building/machining tooling for their lathes, should look into the kits available from mlatoolbox.com/index.html Andy Lofquist is the man to talk to. He has a huge following in many of the machinist's forums. His design of the milling attachment kit for the South Bend and Atlas lathes are superior to those available through other suppliers. Also, look at his cross-slide kits with the T-slot concept intrinsic in the design. Check it out, you've nothing to lose. Disclaimer: I have no commercial interest of any kind with MLA Toolbox.
