Thanks for this excellent video. Being all out of French disc brakes, my plan is to use ancient sash window weights, which appear to be good enough on the inside. The turd I am polishing is called a Shopmaster by the OEM, but is known by those who have this specific misfortune as the Slopmaster. Thanks again.
I've been binge watching your videos for the last few weeks. Hope it helps :) You have such a great wealth of knowledge that you are sharing which is greatly appreciated. You're production quality and in depth explanations are brilliant mate. I also really like your attitude where if you don't have something you make it; especially the ones where the thing just serves it's purpose functionally. No need for some highly crafted object. So much to learn here. Even if you are polishing a turd, it's a finely crafted one too. Highly underrated channel. Thank you.
Man, I can really appreciate the work going into improving a mini-lathe. I also appreciate you sharing the design of your carriage lock, thanks so much.
i guess im asking the wrong place but does anyone know of a trick to log back into an Instagram account..? I was stupid forgot the password. I would appreciate any tricks you can give me!
@Judah Otto i really appreciate your reply. I found the site thru google and Im waiting for the hacking stuff now. Looks like it's gonna take quite some time so I will get back to you later when my account password hopefully is recovered.
I love that slide hammer centre punch, never seen one before. The fact you made it at school just makes it better. I still have a lot of my apprenticeship pieces around, but the only thing I had left from metalwork at school was my favourite cold chisel. I'd obviously got the tempering on the point just right as it rarely needed any sharpening, but using it one day, it simply sheared off in two pieces just as the taper becomes the shaft😢😢😢.
Thanks. You deserve many more subscribers. I found on my minilathe that those three grub screws were actually the only thing stopping the gib from twisting when tool down forces were applied to the other side of the slide. Hence the fact that the grubs mate into holes in the gib is really important (and entirely absent on my lathe), and I guess increasing the number of grubs is helpful also, as is having the gib fitting much better in the dovetail.
Excellent video. Really enjoying this video series. I learned hand finishing from a Japanese tool and die maker over 30 years ago. I didn’t fully appreciate it until I got older. Keep up the great work.
The iron is a little harder than the bed or saddle, but the auto industry can not afford defective brakes, so it is extremely uniform and really nice to work with.
On my "stock" mini lathe I swapped out the gib grub screws for hex cap screws + new nuts + washers. The new nuts were more robust than the originals. This simple change made all the difference in gib adjustment, so others might find this helpful too. The Allen key fits the cap screws better than the tiny wrench in the grub screws. I ground the tips to a point instead of the shoulder. Didn't know disc brakes were cast !? Wow.
Is it best to taper the gib screw tip to match the hole taper? I need to fix mine anyhow as the gib holes aren't aligned to cross slide holes. I planned to use standard drills unless I should get something different. Thanks
Came across your videos as im currently trying to fix/scrape a dovetail on my Sieg Mill (this sucks). But great stuff you're doing. Wanted to comment that I build a CNC Lathe a year ago using Machinekit/Linuxcnc on a small embedded Board (BBB) to get around MESA cards and still get glasscales, handwheel and spindle encoders inputs processed.
Thanks for the feedback. I used Mesa cards in my MAHO with LinuxCNC and really like them. Rock solid, and one of the MESA designers gives excellent support on the LinuxCNC forum. I have a 7i96 ready for the mini-lathe. Probably leave this open loop.
and here i was, just about to throw out 2 old disc breaks, now i know better :) oh and a square thats not square would be an precision angle i guess ;)

Great content but the music is way to loud for my personal taste. I keep having to adjust the volume between the loud music and quiet voice. You have a very good channel with lots of useful tips. a modest workshop too, that's great to see and gives people with similar tools some hope for doing complicated projects like yourself. It shows you don't need to be rich and own all the machine tools ever made.
Thanks for the feedback. That really helps. It is a steep learning curve with the editing. I have watched bunch of videos on audio settings, but don't yet really have a good grip on it yet. This was -9db on the voice and -12db on the music. Your feedback really helps. I'll adjust on the next video.
@@RotarySMP yes, I like a lot this type of work, machining and such, plus you are interesting to watch. Cool in my case i went to a school that in may country we call "industrial school" you have classes in the morning that teach you this type of thing like using lathe, machining, sanding, carpentry, soldering, electricity, construction, and lot more, you very cool and in that year i did a few parts and learn a lot. and well in the afternoon we have normal classes like a normal school, and when you finish this 6 years you ended whit a degree as electronic technician or major master of works, the second is like an architect but whit few limits, the translation is literal so i dont know if in english you have a word that represent better that degree (I not a natural english speaker)
Nice. Is the material of the gib a good combination regarding friction and wear? (metal to metal) Is use of non ferrous metal, brass or bronze possible?
Cast iron is somewhat self lubricating due to the precipitated graphite. My cross slide is not idea, as I made it from steel. Given how long and thin these gibs are, they will distort to conform to the slide and screws so it probably doesnt matter much what your make them from. Bronz or brass have been used by others.
It is a really nicely made machine. Very heavy. I picked it up for €70 looking like a rust pile, but it polised up well. You know the amazing thing, is that company "ARO" used to have its sales office on the Vienna Ring. Today that is all law firms, embassies, posh hotels and restaurants etc. Hard to beleive Vienna was an industrial city with foundries inin the inner suburbs in the 1950's.
Is that the original cross slide ? You cross slide has T nut slots, is that original ? I've never seen that on a mini lathe before, and always thought that it would make a useful addition....
It's probably better to use pointed tip gib screws rather than flat tipped ones. The flat ones will press the gib on the top rather than the middle of the screw because of the slope of the dove tail. This will impart a twisting force on the gib rather than pushing it flat. It will get worse as the gib wears. You can actually see this happening with the small ill fitting original gib.
Thanks for watching. That is why I drilled divets into the gib strip, and put a slight conical point on the screws, so that they are not acing on the slope of the gib.
@@RotarySMP I'm a fitter and turner from the '50's and over the years all the gibs I ever worked on, that had screw adjusters, had dimples that were flat bottomed in the gib.......most of the other gibs were tapered. This allowed the adjusting GRUB screws........ not those cap screws you advocated that stick out like tits on a bull........ to put a square pressure against the middle of the gib. You can buy Allen grub screws with ends that are spigoted especially suited for gib adjustment.
You ALWAYS make tapered gibs too long to start with and then once it is roughly fitted you can do the final finishing and scraping......when it is bedded the length is then determined otherwise you can get it running out of the dovetail if you make it too short initially.
@Ian Pearson is this a tapered gib though? Aren't those adjusted at their end instead of along their length? If it is, I sure missed where the taper got machined into it...
You could really benefit from a good set of precision stones. Especially a 3060 set for the gibs. Would really cut down on the 10-15 scrapping sessions.
@@RotarySMP Stefan sells them on his website. They are actually pretty easy to make if you have a surface grinder. I know McMaster Carr has them and any abrasive supplier including eBay and Amazon. One thing, they come in pairs. You rub 2 together to keep them flat. Kind of like lapping plates. Check out Robin Renzetti's channel, he's the master.
Sorry about that. Making videos is a learning process, and I went down a few wrong turns on the way. I learned to be more subtle with music. Thanks for you feedback.
Seems the RNZAF and RAAF had the same idea for trade training. After the vice they let you perfect your draw filing on an aluminium dove tail, tolerence? You guessed it .001". Ive still got the vice, 42 years later.
@@RotarySMP Thats the one, the groan when the alloy dove tail task was revealed was loud. The vice was about 4 weeks of draw filing, checking for square, swearing, restarting the bits you screwed up. That was back when i could actually see less than a thou clearence between the part and the square (that was the 90 deg one, not the special one you own😁)
@@dhc4ever Was the RAAF also too cheap to purchase new files, so the ones we hd to use already had about a thousand miles of draw filing behind them by the time our course started. Of course there was no amazon to just order a new file :)
@@RotarySMP A long time ago, but yeah some were VERY average. The equipos probably had some, but they had to hang onto them in case someone else wanted one. Training establishments were never all that flush with funds. So which trade did you end up in?
You still having (and using) a centerpunch you made in school when you were 11 is so cool to me
Cool how that shop teacher had us make useful things. The tip was silver steel and we hardened it, so it works well.

The turd I am polishing is called a Shopmaster by the OEM, but is known by those who have this specific misfortune as the Slopmaster. Thanks again.
You got lucky with sash weights which have good cast iron. Given their usage foundries didn't much effort into making them good iron, and void free.
@@RotarySMP I reckon. A surprise result for sure.

Glad you are enjoying it.
Yeah, and a year later, I found it and is binging the whole mini lathe series now:)
Awesome video! Have a small benchtop lathe and mill that need work on their slides and gibs. Never thought of using old brake rotors for gib stock!
Thanks for watching, and the positive feedback. Go for it. Scraping and new gibs should make a big different.
Recently discover this video series, which is super interesting and instructive ! Keep it up !

Never trust the car industry... That's why I always improve the brake on my cars. And ask you to help.
