G'day everyone,
I have owned my import mini lathe (sieg c3) for over 2 and a half years at this point. I think it is a very capable little machine, and considering the price that I paid, the parts that it can produce are very decent. It can even turn steel with over a 1mm depth of cut.
However to get to this point I have had to make several modifications and upgrades, in order to fix issues from the factory, and expand the capabilities of the lathe.
In this video I will be showing you all the upgrades I have done to the lathe over the past 2 1/2 years. Some of the mods I have shown here on the channel before, and they are linked as follows.
