Cutting Tool Size for 9x20 lathes?

[Graybeard]

I'm now looking at buying a Sieg 9x20 lathe. I would like to know which size cutting tools most of you who own similar size lathes are using, ie: 3/16", 1/4", 3/8", 1/2", etc.?

Thanks,

Cliff.

Hi Cliff,
I own a Grizzly 9x20 and it will accomodate tools up to 1/2". However, I rarely use such a large toolbit. I use mostly 1/4" - 3/8" toolbits, smaller ones for closer work, larger ones for taking off more material. I'm becoming a great fan of the indexable tooling and I use that in the 3/8" size.

Cheers,
Phil

The 9 X 20 import lathes are actually designed to hold 10MM tools.
A 3/8 tool with a .030" shim under it seat the tip at .011" above
center. That set up cuts perfectly on my Grizzly 9 X 19 lathe.

Thanks for the great responses - just what I was looking for.

So, if I made a custom tool holder I could build in that ".030" shim" and make it even easier...?

one of the first upgrades that is typical is a quick change tool post these have built in height adjustment so no need for a shim if you go that route. If you do decide to make your own tool holders look at the ones Marv built.

Thanks, Tin, I may buy several "upgrades". I stumbled on a site this morning that has several "goodies": http://www.harrisson.biz/

Nice site one I have not seen before.
www.littlemachinshop.com also supports the seig machines.
there are several sites that show shop made upgrades. These are typically simple project that are skill building as well as shop building.
here is the link to Steve Bedair's 9 x 20 page.
