I would but I looked into it and i can't find anybody in town who does it, I'll Just risk it because it's a learning curve for me how this thing works but thanks .

Hi Laytonnz,
You've made some great progress! Congratulations.
You will know that machine inside out.
By the way, even if that is a crack, it does NOT mean the entire machine is scrap. I know I differ from a lot of people on here, but I do not have the budget for new machine tools, and even great-shape used ones can come with a high cost.
I believe that as long as you ensure it is safe then go for it. Further down the road, if it does cause issues with accuracy, you can start thinking about how to improve it.
It's also about setting expectations. I know I'll never produce NASA-grade parts on some of my worn equipment; but I am also sure that I'll never need to! I always try for the best accuracy I can get, but it's all relative. There is such thing as "good enough".
For me a working, inaccurate machine is infinitely better than no machine.
Keep up the great work, you will have a very useful tool when you're done.

I spent the good part of 3 hours sanding the bronze bushes to fit the spindle again due to abuse over the years and i cant afford to get nice new ones machined so what should i use for lube on re assembly? Just normal oil or greese?

Use oil to assemble with. ISO 46 or 68 or way oil is my preference.

have to disagree on the good tie-down job
actually it is a very bad job
the ties are only holding the lathe down, but do not secure it from tipping over sideways
two ties to each side going through the bed/headstock and back to the side would have been the way to do it

I have never seen that before.......it makes me think I should go inspect all my chucks with a fresh eye for this.........
I would guess that a cracked chuck had been dropped.
This crack is right at the corner of the t-slot; a real stress point!
I imagine when tightening the jaws that crack would open up.
Laytonnz - How did you first notice it?
Is there any other sign of it being dropped? (perhaps a dented edge?)
Way to make lemonade!

Ohhhh I think you are going to fit right in here! Keep them coming. Learned a lot from you already. Thanks, CG
I actually didnt notice it untill re assembly once all the oil and chips where gone i seen a chip in the retainer ring so i lined it all up and noticed the crack i gave the 2 retainer rings a slight twist and they crumbled into pieces oh well, im going to vists my machinest friend today to see if he can spin me up a new backplace for a different chuck
This is how the rest looks at the moment just primed the tail stock this afternoon
Ideas on how to remove the back plate? Looks as if there is a crushed spacer/washer thing in there I'm unsure how it works or how to remove it I've tried putting the chuck back on and using the jaws as leavers the chuck is stuffed anyways so can't hurt it anymore I found another hairline Crack through the other side of the body as well I have tried strapping the spindle to a large bar on the floor to stop.it rolling around but I can't get this thing to budge looks as if it's never been removed ....
