I bought this lathe and a mini mill from Grizzly 6 months ago and have not regretted it.
I need to make a distinction clear: buying something, anything, from Grizzly and the quality of that something are separate issues.
My buying experience with Grizzly was very good. I have complete faith and trust in Grizzly with regards to them standing by their products and working hard to satisfy their customers. I will continue to do business with Grizzly and strongly recommend you give them a try. I say this because there was an issue with shipping in which several parts were lost - Grizzly shipped new parts and did so without question, very quickly, and at no charge.
Now as to the G0765 7" X 14" Lathe. For the money this is a very good buy. However, it is a long way from perfect. I believe the following are the three most significant faults with the design.
First, there is no good way to lock the X, Y, or Z (longitudinal, cross ways, and diagonal or compound) axes. Modifications to accomplish this are possible.
Second, the manner in which the Y and Z axes leadscrews are attached is a very poor design. This makes it very difficult to achieve smooth movement along these two axes. I have completely given up on the Z and simply locked it in place at zero degrees using the gib grub screws.
Third, the Z angle cannot be changed without loosing the cutting depth, and adjusting the Z angle requires backing the tool holder out to very nearly the removal point.
Build quality is another issue. In most areas it is rather good while in others quite poor. On my lathe there are a few factory mistakes that should have been caught and corrected. The most common is crooked drilled and tapped mounting holes.
I would only recommend the G0765 Lathe with the admonition that it be thought of as a kit and a work in progress rather than as a ready to use lathe.
