Finishing Tool

Here's a tool I like to pass along. I found it on yahoos 7x12 mini lathe forum. I have been using it for awhile now and always got a pretty good finish.

Nice find on the tooling tip. They use the same principle on that is used on a wood lathe. With a cut like that you shear off the material rather than scrape it off. It will be interesting to see what the response is from the rest of the members.  :ddb: :ddb:

Cheers  :beer:

Yeah, I've got an observation. In the pic were he says the tool is in the cutting orientation. Why does the tool look like it's upside down?

Then in the third pic down from that he say's "Here’s the finish ground and honed tool bit mounted in my QC tool holder ready for use." It still looks like it's upside down.

Now I'm having a  :beer: while I'm typing this and don't think I'm drunk yet. So could somebody explain the optical illusion to me.

Also I have to vent a bit here. Again it might be the  :beer: but the pics of it mounted in the machine all look a little dark to me. Can't make out any detail.

Ok. Enough said. Back to my  :beer:

I mean no disrespect to you khand. Thanks for posting that but I just needed to ask those questions since it does look to me like it's mounted upside down. As far as the picture quality goes they are good, but a bit on the dark side.

Look closely at the last picture on page 4. That shows clearly the position of the cutter to the work and how it will use a slicing action rather than a scraping action to remove material. This is the same idea that wood turners use when using the skew chisels. Hope this helps.  :lol: :lol:

Cheers  :beer: :beer:

It appears to me that the left side of the HSS tooling is used to make the cut. It is ground at an angle, with the side cutting edge bottom closer to the headstock and the top closer to the tailstock.
