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.
