There must be lots of little stores that scrap machinery in Hong Kong.
Do you have a place like Singapore's Simlim Tower, where they sell lots of Electrical items. This would be the first place to look.
If you just want to buy a unit, there are several links on the site to people who sell kits.
Thanks a lot. In Hong Kong, more parts will not easy to find. Example the linear bearing. I need to contact the retailer and order it. Another of stepper motor, although I know too many made in China. But I don't know which can fit to me.
Final, I can't to looking for the motor controller in my location. All kind of product need import from oversea. If possible, I would like try to looking for another supplier and order it. Just a little concept at first. May be I will purchase a full set machine. I really wants to hold the bigger size, alook as well as 3' by 4'. Really expensive of large router.
Take it easy.
