hallowing tools
I've got one of the curved necked hollowing tools that I would describe
more as a fancy curved necked scraper by sorby that I've never been satisfied with. I've heard other hollowing tools mentioned from time to time but I'm not sure if any of them are any good either. any suggestions? |

Google search will produce the Mangiamelli treatise. Some now have
planer-like capability, sort of a ring tool with a depth-limiter. Learning curve a bit different there than simple scrape, though both will certainly work. Remember, downhill rule still gives best results when cutting. I use a pointy gouge to do the initial and as much of the interior as the design will permit, size depending on the neck opening. This makes waste removal easier, as shavings run down the flute of the gouge. Take a look at Wood Central's grind library for David Ellsworth's detail gouge grind. Looks similar to what I've settled on. The continuous curve, versus bevel, makes it possible to take as light or heavy a shaving as you care to without an abrupt bevel-jumping grab. Even the scrapers work better once there's room in there so they don't jam. Narrow bits for gross work and broad scrapers for smoothing - I've the big Sorby "Hooker" tool and the Stewart small - seem a good way to go if you don't have a ring. They produce a worse surface, but up/downhill make less difference in jamming and grabbing. "william kossack" wrote in message news:9HSHc.54410$IQ4.51811@attbi_s02...

hollowing tools
I think you are referring to the Sorby tool that has a sort of swiveling
pointy tip held on by a Allen screw with a bent shank. I don't like mine much either. It works well only on very small turnings. I tend to use mine only where I don't have the room for a better tool. I think you might be more satisfied with Sorby's multi-tip hollowing tool. Try it with the little half-round 3/16" cutting tool tip. I think you will get much better results. I consider this to be sort of an entry-level hollowing tool. Do as much hollowing as you can with a gouge, then switch to the hollowing tool. As your bowls and vessels get larger and deeper, you will need to get more sophisticated with the tools that you use. You're on the right track. Start simple and work up, as your skills improve.

This is where Sorby goes wrong and where Stewart and John Jordan succeed. I use the Stewart hooker tool with great success and am looking forward to getting a Jordan soon. They both have 3/4" shafts so they'll go into your existing handle. The Stewart hooker neck can be bought at Craft Supplies, and the Jordan tools can be found at Stubbylathe.com. -Jim Gott- San Jose, CA I also use the Stewart and am curious as to what the Jordan has that the Stewart doesn't Jim?

How are these different from the average spindle or bowl gouges, or are they just a regrind of one of these? TIA Ken Moon Webberville, TX |

The picture on Wood Central I referenced is a pretty good example of a
pointy gouge. Essentially, mine are a detail gouge with a point, and very long ground-back wings, and some cheap spindle (cylindrical) gouges with a slightly milder point. No bevel to them, just a carving-type curve to the edge which allows me to choose my depth of cut by rolling along until I'm grabbing as much as I care. You can see the pointy detail gouge in use at http://personalpages.tds.net/~upgeor...ing_inside.htm hogging out on a flat bowl. When cutting end grain it's capable of some incredibly fast work, as long as I can get the toolrest close, and with the point, it's not necessary to bore a hole to get piece started. You push the point in, roll left and sweep out and up toward the rim, then, in one uninterrupted move, roll across the point to the right edge, sweeping down and in. Forged gouges are what gouges used to be. http://www.leevalley.com/wood/page.a... rrency=2&SID= shows the two big ones I've been able to talk the family into getting me, and the small one I still want to get. You can see how I rub the bevel (yep, Arch, it rubs) at http://personalpages.tds.net/~upgeor...20Pictures.htm The advantage to the forged style is the uniform thickness. You can grind the same bevel angle all the way across, making it capable of working like a curved skew. (some people grind their skews convex to work like a gouge, so why not?) Where it truly excels is in making the turn into the bottom of the bowl. You can dip the nose as you come across that part where you always tear out, and keep a continuous shearing action, rather than picking up and tearing the uphill sections. http://personalpages.tds.net/~upgeor...oth%20Four.htm The bowl I'm cutting is yellow birch with a lot of grain reversals, and it almost shone from the gouge. Check Darrell's site http://www.aroundthewoods.com/roughing.shtml to see an Oland tool - basically a bigass pointy gouge - at work in the hand of a production turner.

I also use the Stewart and am curious as to what the Jordan has that the Stewart doesn't Jim? M.J. Orr BRBR The Jordan tool has the cutting tip coming right out of the end of the steel instead of having a round disk and a nut. This lets you get thru a much smaller opening because it's more streamlined. Take a look at Stubbylathe.com and you'll see what I'm talking about. -Jim Gott- San Jose, CA |

Seems that I have a couple of my own "pointy gouges", just that I call them fingernail spindle gouges. I use them in much the same fashion as you describe. The convex bevel comes from not using a jig to grind. I don't have any of the forged gouges, but I can see where they could be a good addition to my "arsenal". Now I'll have my own translation to your posts. {:-) |

I'm not really into making my own tools at this point

William
Just a thought or two here on making your own tools. As you say, at this point you are not into making your own. Makes sense to me. I like the thought of making the tool that makes the piece, but not everyone likes to make tools. However, for hollowing the tools are easy. If you do general wood working you have all the skills. Basically you need an Oland tool with a straight tip and one going off at 45 degrees. Both should use a 3/16" cutting tip. If you find that you do not like hollowing, you are only out a few dollars. Recently I made myself a pair of 5/8" shaft, 3/16" cutting tip hollowing tools with arm brace handles for less than C$20.00 total. Quite the savings. -- God bless and safe turning Darrell Feltmate Truro, NS, Canada http://www.aroundthewoods.com |
