## Product's reviews:
- Right parts - very very please thank you
- Gear box oil - This has been very hard to find. It’s the oil spec’ed for my 1950s Rockwell wedge bed planer gear box. I haven’t found it anyplace else.
- Needle gear - I'm very happy with my purchase. I found exactly what I was looking for and I received it in a couple days. I will recommend your company to others and I hope I can deal with you again. Thank you!
- New lead screw gear. - Used this gear on a new lead screw l made for my old 1919 LeBlond belt drive lathe. It worked great for my application.
