Hi Darren Did that many times before. Just can't stand the gunk and mess that ends up in my lathe. I use coolant as well whilst doing parting etc. and that combined with all this rusty, muddy-swarf from the turning made a recipe for disaster which eventually forced me to empty the Coolant Tank and clean the whole bloody thing. That was a real pita. ~!@#$%^&*(  Learnt the hard way, clean the stock and work tidy. I am a bit of a fuss pot and like working neat, when ever possible. Guess it's each unto his own.

Charlie has been using the wood lathe quite a bit making bowls, had some 5/8 round carbide inserts so made up a scraper for him. Cherry handle with a 1 1/4 copper pipe furl, the body was a rusty chunk of 1/2 inch square, again the surface grinder came through. Glad to hear that Vinny. These inserts seam quite sharp, hope they work well have a package of 5, with revolving them they should last a long time. Lee Valley has a very similar tool but they want something like $170 for it.
Free advice is worth exactly what you payed for it.

Using two chuck keys machinist make it look like a no brainier. One aspect of a 4 jaw is that it holds a part/bar stock much more rigid than a 3 jaw. Typically I'll start by aligning the 4 jaws equally by eye to one of the rings cut in the face of a 4 jaw. Scale the part/bar stock and adjust two adjacent jaws 1/2 the difference. Put the part/stock in then run in the other jaws so they are snug. Set up a dial indicator and check 4 points corresponding to the jaws. Tighten high and loosen low. Make small adjustments until you've got it within .010" TRI or so. Then start tightening OR loosening opposing jaws watching your adjustment by the movement of the indicator. You'll be finished before you know it. BTW, this is also a good technique if you have an out-of-round part or material. Get jaws 1 and 3 as close to each other as possible. The same for jaws 2 & 4. You may need to work back & forth between the two sets of jaws. I have a 8" Buck 6 jaw and love it. It's the most accurate single adjustment point chuck I've ever used. If you're doing a short run it can be adjusted for the exact diameter/hex of your bar stock to run with minimal run out. It's stable mates are a 12" and 6" four jawed chucks, a 6" 3 jaw (also used on the RT and the indexer for the mill) and a collet chuck.

Immerse the item for several hours and you will be amazed at the results also. Another tip. "Lacquer Thinner" used as a cutting fluid is excellent when tapping aluminium, leaving clean sharp threads; this works especially well for smaller taps, such as 2-56 as an example. Mike

Lee Valley has a very similar tool but they want something like $170 for it. Not even a problem with an interrupted cut. What's nice about the round inserts is they have many sides. Gets dull or chips and all it takes is a slight rotation.

Good point and understand that, after asking the question, looked into them a bit further. Discovered they scroll, had it in my head the jaws were independent... Amazing what a bit of reading does LOL It would take more than ability to turn thin walled tubing to justify the expense for me. Not seeing much of that in my future. I'll pocket the $ for now and use it for tooling. Thanks Greg

What kind of finish did you use? Is it a typical friction polish? Also, have you ever had problems with the antler splitting over time? About half of those I have made have split, and that's with dried antler.
Full of ideas, but slow to produce parts
