Lathe problem

there are a few things you can do.

 

1.

bolt the lathe down and add lots of heavy bags of sand or weigh it down as much as possible.

 

2.

buy a nice big heavy lathe that is all thick cast iron all over and in the region of 350kg plus.

 

3.

reposition the work so it's as centered as possible on its C of G but this is not always possible.

 

4.

turn at a very low speed.

 

5.

use another bit of wood.

 

 

 

finding the center of gravity is easy once it's round. let it roll on a flat level surface and when it stops rolling around strike a line vertically on both ends and this will give you the correct plane to find your center on once it's back on the lathe.

Thanks for that, the last bit is brilliant - simple, obvious solution - once someone explains it to you !!!

 

I'd love to go for option 2 but realistically I'll stick with option 5 if option 1 doesn't work !

Have a look on you tube for lyle JAMIESON mounting a blank, he uses a simple common sense approach to find the C of G of any blank which then allows you to turn at a faster speed right off, which in turn is more comfortable and easier and gives better cuts.

 

You may also find that counter intuitively if a piece vibrates you can go past that by upping the speed a tad, common sense applies though and wear a face mask. Some pieces will always vibrate due to dense spots in the timber itself, on larger pieces anyways, this is especially noticeable on the hobby lathes.

 

When I had my first lathe I boxed in the frame and filled said box with damp sand, cured most issues, I never did bolt it down either. I preferred it to walk rather than stress and bend the pressed steel stand.

Take a leaf out of the pole-lathe turners book and hack the corners off with an axe. If you can start off with a rough octagon rather than a square, it is bound to go more easily.

Sorry guys not ignoring any advise but was reluctant to drill holes in the bench , and yes I totally need a bandsaw but I have not been able to work since January F###ing skint now so a bandsaw will have to wait unless anyone has one they don’t want any more .
