Re: My new 4 jaw chuck for rotary table
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-

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
Use seal ball bearing?
On motor they over 20,000 hour of life.?
A good brand is 40,000 hours.?

At time I put in what had and had shorter life.

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

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.
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.
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.
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)
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.

Re: HOW TO KILL A TOPIC Re: [7x12MiniLathe] ANSWER TO GUIDE RULE - OT
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
6) Size for a mini lathes and mini shops.
7) No guns
8) Nothing illegal
