First I'll say I am totally new. First post here and also my first machine is still in my truck in the crate waiting to be opened and cleaned and such before the first use.
What I have is a Grizzly.com G9729 Combo Lathe/Mill unit. I drove to the store and got it.
It's the best I could afford and looks decent.
However this model has a threaded rod for the cross feed that looks to be only about 3" threaded. Specs say "Cross slide travel: 3-3/4" "
The next model has a full feed acrossed, I think the bed on that one moves about 6-8" or even more.
How hard would it be to turn more threads in a cross feed rod like this? Or make a new one. I beleave this rod is what gives the measurements for turning depth also so it has to be pretty precise I think.
Also I had not thought of it till I got home with the machine, but if the table only feeds 3 3/4" and the tool rest is mounted on top of that table, does that mean I can only face a plate 3 3/4" at a time? Like a flywheel or other large diameter disk. My swing is supposed to be 16 1/2" so I figure in one pass I would need at least a 8 1/2" cross feed? Is that correct?
I will want to face 16" disks from edge to center and it does not seem correct to me that I would have to do half then reset the tool and start in the middle to get to the second half.
The salesman is checking to see if I can get a threaded rod from the larger unit and install that in this one, or the entire larger bed. However I expect it will be more of a buy it than them just giving it to me exchange, and probably expensive too.
I appreciate any help on how to fix this thread issue. If you want to see the machine and specs of what I bought I am posting the link for it. I think the parts list may be online also if anyone wants to look at the rod and see what I am talking about and how this one is setup. I don't plan to try turning it myself since I don't have a clue yet how to run this machine. If I should just make a new piece from blank rod I could try that in a few weeks or so and suggestions on that would be helpful also.
