Lathe Mods

Darren:
The bearing No' 30206JR for the inner race and 30206 J-N for the outer race. Those No's are all you need for any bearing supplier.
You do of course need two sets.

The spacer you need to modify is already on the lathe. I managed to shorten mine on my lathe before fitting it. When you get to that part you will realise what I mean. It's part of the bushing at the back of the spindle just under the pre-load nut. Just lathe it with no pre-load. Easy cos it's plastic, if it where metal I doubt you could do it without another lathe.
I had no choice at the time as I only had one lathe.

Hope this helps
Darren

Here I am again Eric, piddling on your parade.

Can you tell me the reason for the risers?

The reason being, if it is to turn larger items or fit a larger chuck, I honestly don't think the gear trains will take the pressure of the extra torque required to cut or swing larger items. They really are borderline.

If you look at the ML7 which has about the same swing as yours, they are regularly fitted with riser blocks. But if you look at how they are made, they can take the extra forces involved. Massive metal gears compared to yours, and a motor that is about 3 times the size.
These lathes are made down to a price, so everything on them is really at the max they can cope with. That is why when you go for a larger lathe, they start getting made stronger and stronger as they go up in size, and that is what you are paying for.

It is your choice, but honestly, for the extra work involved, and the suspect strength of the machine itself, I personally would accept it as it is, or if you want the larger size, spend your money on buying the next size up.
