Re: ANSWER TO GUIDE RULE - OT
开云体育Dave’s real hobby is beating dead horses.? ? Glad to see you added “OT”, I guess Dave couldn’t figure out how to do that (despite telling us how).? Lol. ? I’m pondering making a flip-top bench with my 7x12 on one side and the mini-mill on the other.? Wish me luck, I think I might need it.? (Probably should measure the mini-mill before going too far.) ?

Sorry to come to this a bit late, I have 2 points though. ? * I’m not sure what the problem is, as anyone can add OT to the title, as I have done. So why the continuing debate ??? ? * I am amazed at some of the replies, not only to this but others as well. Where part of the reply is in understandable English and the rest is gobbledygook !!!? I can understand and forgive ?differences where clearly English is a second or third language. But where part of the message shows the writer understands English, I despair. Doesn’t anyone read through and correct any more ? ? ??????????????? Ellis ? ? I forgot rotary table. If rotary table goes a mill it is OT. But if goes Mini lathe it is $&#^$ I guess it depends on if you interested read a about putting on a mini lathe if on topic or off. ? If do not like what they wrote then? write moderators and say OFF TOPIC and ask to have it delete post so no has anything thing to read.?? ? The bottom for group to be interesting is have something to read about and better to comment on too. ? In November of 2023 I finally purchased a mini after reading about mini lathes since 2005. The resoan thinking a mini lathe in 2005 changed by time purchased.? I chose to write about here and gave everyone here some read and write about.? ? No one goes out buys a lathe every month. My first was a garulatoin present it only down payment on a $10,000 today same lathe cost $80,000 had for over 30 years. My next had for 20 years. The point is most do not go out and buy new lathe very often. So hard for very here to say a lot? .? So we all here need more than jest the mini lathes to talk about or this would a very slow group ?

I'm out-I feel that davesmith1800 (if that is his real name) should have been banned by the moderators long ago. I just can't be bothered to incessantly?exposed to that brand of nonsense (what little of it I could make out due to poor English and even worse spelling). Good luck to you all- |

Re: Dismounting the headstock bearings
开云体育Jon, Thanks for your reply I annexed the detailed drawings of both heads. About your 1st remark : No, there are no parts in between the bearings. Confirmed by the picture. What is in the middle is a bracket supporting the Hall transducer, the magnet is stock on the shaft. As per the Arceurotrade dismounting guide, everything seems to me mounted with a press, which is peculiar for me. I'd agree for both external bearing rings and the chuck side inner one but not for the inner one of the opposite side. Otherwise no preloading would accurately be possible. As far I don't fully understand, I won't force and/or heat the housing to unstick the bearings. I'm gonna go to youtube as you suggested.

Re: Dismounting the headstock bearings
The word preload is not best in world on any thing.?
?
Most will over titeon.??
Some manuals I had said tieon till finger back off one two notch on bearing retain nut and so bear spins .?
?
If you over titeon the bearing it will stop? (it needs room for heat expansion).?
?
FYI Most mini lathe have a class 1 ball bearing. It better to have class 3 or greater. I found class 8 is just over kill and very costly too

There are several gears and spacers between the 2 bearings that have "STACKED TOGETHER" to create a "SOLID" column of material to be squeezed by the adjusting nut.? You have to thin down one of the spacers due to the different dimensions of the new bearings.
Your wheel bearings do not have a solid spacer between the inner and outer wheel bearings, the lathe does by the accumulation of the 2-speed drive gears and spacers,(do you have a 2-speed lever on the back or direct drive)
Perhaps search YouTube for "mini lathe
angular contact bearing" and reveal this -->?

Re: Dismounting the headstock bearings
开云体育Sorry, I wrote the message on the web page and i sent it too
quickly. Here's it again : Hi, I've some trouble adjusting the clearance of the headstock
bearings on my lathe. It's a WBL210 Weiss lathe ; max Dia 200mm,
300mm between centers, roughly a 8x12" lathe of the same design as
the 7x12 ones.
?
The surface finish was not as smooth as expected: even with
shallow pass with slow motion. It was looking like a ~2mm pitch
thread with a very low roughness pretty lower than 0.1mm.
Probably the leadscrew pitch amplified by the gear train and some play in between the spindle bearings. Tightening the nut at the end of the arbor improved the situation but I couldn't manage to tighten it farther. The bearings seemed to be blocked by something. The drawing doesn't show any obstacle however. the bearings are 30206, tapered roller type. On to the other hand, 6 months ago I attempted to troubleshoot the spindle of my milling machine (model? VM18L from the same manufacturer), ending by tuning the deep groove bearing clearances. It went the same way as the lathe. But since I didn't notice any discrepancy, I let it as it was and remounted the spindle. Several times, I've replaced tapered bearings on the wheel hubs of my cars without any extracting issues. They went well adjusted but not needing any great force to get them. I assume that the accuracy of a machine spindle being greater than a car's hub one, leads to a tighter adjustment. But, does it really need an extractor or is that a specificity of this manufacturer or even a bad quality level ? I found some clues on . The bearings are 6206 deep groove or 7206 angular contact ones. The procedure uses both an extractor or a press but doesn't specify the force. I'm puzzled by the fact that I can't manage to tighten a bit more the nut because, normally, the external bearing should slide against the shaft otherwise it should be impossible to adjust the clearance. Please, may a specialist bring some light over all of this and/or provide other URL to relevant information ? TIA |

I am responding to your question?
If go not like talking about rules then click MUTE?

This why some groups just slowly dies.? This is not my thread.?
If buy a mini you talk about what next. Move to a different group or talk or talk about things to do with lathe.
Like Beyond the Mini lathe is what saying today?
?
My real thread is on putting rotary table on mini lathe?
Are even reading this thread?
?
I would to be talking about my mini lathe / rotary table here and almost no one is talking about .?
?
My next thread after I finish the table is wood turning on a mini lathe?
?
If we had a few simple rules?
?
1) No political
2) No ads
3) It ok with Any one's Wife / Girl friend?
4) It is ok for any one's child/ grandchildren see it too.
5) Must have something to do machine work in the ot

开云体育Hi Dave. Before you question another’s email, please check your own, see below. It’s a good idea to read through a message before clicking on Send ! ? I agree with Pierre-Raymond and I am surprised that the Moderators have not stopped this turgid topic. Please think about ending it. ? Finally Dave, if you are so keen on following this subject. The answer is easy, set up your own 7x12 group with the rules that you wish to have and leave this group. That way everyone is happy. ? Personally I like the group as it has always been. ? ??????????? Ellis ? ? ? We have members leaving.? To little to talke about is basic reason.? ? Most do not cancel they just not to come back.? ? I am doing my part by posting on how adding tooling to my mini lathe.?? ? So what are doing??? Please post photos ? Dave? |

开云体育Yes.? If you log into the groups.io site to read messages you will see that Mute button to mute the topic.If one has individual messages sent to your email address, there's a link at the bottom of the page to mute the topic.? You have to login to groups.io to finish that process.? Sorry if I was unclear on that earlier. Hope that helps. A couple of comments.? Messages have been a bit low at times.? No idea as to why.? Getting back on topic, I still need to put my HF 93212 lathe back together after making some adjustments to the carriage.? That's a project for a warmer day.
