I have a Grizzly lathe (G4003) and a Grizzly mill (G6760). Neither has carriage/table locks. Has anyone fitted their lathe/mill with locks, and if so, what design did you use?

Thanks

The G4003 has a carriage lock on the top surface, tail post side. It's shown on page 24 of the PDF manual. There is no cross feed lock but one can be easily added. Don't know about the mill but the features list says the locks are there.

DP, I appreciate your reply, however page 24 of the manual relates to setting the gibs and tail stock operation. Also, can you point out where in the specifications it mentions a lock? Ditto for the mill.

Page 38 in the PDF manual on the Grizzly web site.
A square headed screw on top of the right side of the saddle.

I DO like that lathe.

The mill and lathe both have locks ---

You are aware that the term "lock" is - usually -referring to a screw with a handle/thumb nut/screw head/hex head or similar that merely screws into the gib of an axis and applies pressure to the gib either locking movement or severely restricting movement. The lathes saddle is a bit different -- it was described by a couple of the other posters

It should be the long black bolt head protruding upward from the saddle, just to the right of the cross slide in this image:

Many table and cross slide locks are a separate screw which applies side pressure to the gib for a given axis. On lathe carriages, it can be a separate part or included in the saddle casting, pulled up against the underside of the front way when tightened.

I'm looking at Page 24 of the on-line PDF manual and it has a picture at the bottom of the page that identifies the carriage lock. The text describes the gibs and there's also a steady rest shown.

For the mill I saw on the Grizzly on-line product page the features list and table locks are included. They don't seem to have an on-line manual for that machine.

Thanks to all of you for the help, including opening my eyes to the idea that the locks usually tighten the gibs to prevent movement. I'm used to handles that do the same job by locking the movement externally.

And yes, there are locks that I've found on some movements, some of which I covered when I installed the DRO readouts. Bad me!

Thank you all again.
