Jay I remember seeing that and it came to mind after the accident. Think you can put your hand on it again??

It seems to give a lot more rigid support that way and putting the compound back on is easy when you need it for threading.
When doing jobs that really need to max out the lathe capabilities, it seems it would be stronger


Looks like a plan..

Now Jack that is the ultimate solution. I'll be looking for one. Thanks.

The main problem is the original hold down bolts were too puny to do an adequate job. I will fit two T nuts to grab all the meat available and cover a longer area. Also will fab a support for the front of the compound to take up most of the force. That should work.

One other thing. We removed the saddle from the apron and saw another horror story. When the apron is filled to the right level in the sight glass it does't reach any gears. They were as dry as a March wind in Lubbock..I told Dave to fill the damn thing up til it runs out of the highest point and make a dipstick marking about an inch lower. Its slinging oil now. Things sound better and engage smoother. The headstock gears will get the same diet..

I would recommend anyone with a chinee lathe to investigate.
Moe can you post pics of what the hold down bolts look like I took mine off and they seam to be gripping all that there is to grip my g4003 is not quite a year old and I'm wondering if they changed them .Also about the oil problem when I bought it the grizzly salesman told me the first thing to do is get rid of the china oil so I pulled the top off headstock and pumped it out and filled it with the top off and also drained and filled the saddle.

Using the parting tool is my least desirable lathe task, right next to knurling.
I bet that was a drawers changing experience. I'm glad he wasn't injured.
Me, I'd ten times rather knurl than use a cut-off tool. :-)

I missed this thread the first time around, either for lack of knowledge on the subject or it just slipped my radar.

Big Blu's poor excuse for a compound hold-down isn't much better than what's shown in the pics here, and only has a two point mounting system. A couple different companies make a 4-point system but I keep telling myself I'll make one myself one of these days. I fully expect a catastrophe like this to destroy it before I get that done.

I regularly groove with a custom cut .140" tool I made for o-rings. It has some serious grabbing power when things start to get too sticky, but usually my fixture breaks before any part of my machine. Good to build that sort of thing into your setups when you have the chance .

I'm getting pretty confident with regularly parting off work on smaller pieces, at high speed, lots of oil, and continuous feed. Indeed though, when things go wrong it does so in a hurry and will almost always cause your heart/body to have reactions you wouldn't want to display in public .
