Welcome!
Yes, find a club, as local as possible, and join.
take care over what "Refinements" you make. By all means make / add accessories, (Saddle or Cross Slide lock, Leadscrew handwheel etc ) But be careful what you dismember as part of the "improvements".
If you are not sure, seek advice. Turning the wrong screw can cause you an awful lot of grief. You don't want to change a reasonably accurate machine tool into an expensive door stop.
There are plenty of folk on here, and writing in MEW who HAVE made improvements to their Chinese lathes.
If in any doubt, seek advice.
Good luck and enjoy yourself!
