Metso Lokotrack LT120, Jaw Crusher.

Now it was time to turn the flywheel and the extra weight for the beltwheel.
I only had a 100mm chuck on my lathe and it cant hold pieces as large as the flywheel so I had an chuck adapter made by a local machineshop to get the boltcircle right and then I turned the last steps myself.
Now I can fit a 125mm chuck and this lathe will last me a few more years!

Here´s some progress on this project.

First I turned the internal hole for the flange mount on the spindle.


Then flipped it to turn the outer flange to fit on the new chuck.
I had 0.01mm runout on the spindleface with new backplate.


Here mounted and started to turn the flywheel, I had a runout on the chuck on about 0.03-0.04mm, that was measured on a drillbit in the chuck. Good enough for me.




And just a pic of my 10 year old chinese lathe, it has served me good over those years.








Also both covers are printed, also made on a cheap Wanhao 3D printer.

Fine machined and printed parts you got there. Have you evaluated adjustable bottom opening/distance of the jaws?

Thanks!

I don't really understand how I can do that? Can you explain a bit more please.

I see now you got a joint for a threaded rod as part of fixing the lower end of the moving jaw. Than one got the possibility for a adjustment, say +/- 5mm should do. manual adjustment is fine

Now I get what you was talking about, I thought it was the jaws on the chuck!

Yes I have adjustable jaws in the crusher, I can adjust them probably 10mm in each direction.
