Default lathe 'V' groove or Bearings

Hi,

Looking into getting a lathe, I see that they do a 'V' groove type and one with bearings.
What are the advantages or disadvantages one over the other. The only thing I have heard is the Bearing type clogg up after a while with copper.
What do you think?
Thanks

In my experience go V-Groove!!!! The bearings will eventually seat and cause vibrations which are barely noticeable by feel, but can mar the finish on the comm.

V groove, and get a diamond bit while you're at it. I'm running the same diamond bit and V groove blocks in my ancient Twister lathe since the day I bought it.

V groove is the only way to go.....the bearings, while they may be of the sealed type....those stupid little copper shavings will find their way into them within time.....and then you get slight little stutters that you cannot even see with the nekid eye....and get a crappy cut....

V groove is the standard for accurate cutting, as long as it's lubricated, it will stay accurate forever (virtually).

Ok cool,
So now I'm looking at the Hudy lathe with V grooves and Diamond tip , it says to use a graphite powder or will some bushing oil (Zubak speed lube) do the trick.
It's good when guys reply but when you get one top motor tuner giving tips that's awesome, way to go EddieO

Don't V groove eventually destroy? Can you use it forever?? If you lubricate it it will live forever or it will only prolong it's life?

With any type of tool or tooling, they will wear out in time, especially if not lubricated or used properly. You will get longer life and a better cut with V blocks. I recently upgraded my lathe with custom V blocks, and I noticed a big difference on the first cut.

I know alot of guys that have the Hudy Lathe with the bearings and they have no problems with them.

I guess if the bearings did get grittty can't you just replace them?

I don't think you can just replace the bearing's, you need to get new bearing guides and they are expensive.

When you guys are cutting do you 'go in' a notch depth a cut or half. Just I've seen a notch depth and it seems quite a lot of copper chunks come off.

Get the V-Blocks. I bought my Hudy lathe years ago with bearings and wish I known to get the V-blocks during the initial purchase. Now its better to sell the whole lathe as-is and buy a new lathe with V-blocks due to the 90-100 bucks to buy V-blocks seperately.
