Roughing a bowl blank??
Hi all, I a have huge roughing gouge, trouble is it's not supposed to be
used for bowl blanks. Apparently it's not designed to cope with the alternating "with the grain, against the grain" cutting. I know some turners use them on bowls but the practice is said to be dangerous. Fine by me, I'm all for safety. BUT, what 'do' I use to rough out a bowl blank? Your comments would be appreciated. |

Your comments would be appreciated. I use a 1/2" bowl gouge, for roughing out both the inside and outside of bowls. The bowl gouge is preferable for a bunch of reasons. The deeper flute of the bowl gouge makes it stiffer than a spindle gouge. Thus it flexes less, making it more controllable, essential for when you are reaching into the inside of a bowl. It takes a much smaller cut than a roughing gouge (more properly called a spindle roughing gouge these days), keeping the forces on the tool more manageable. And when a catch does occur, the beefier tang of the bowl gouge makes the tool stronger. I haven't seen it, but I've heard enough stories of a spindle roughing gouge blowing apart at the handle when used on a bowl and the end grain caught the cutting edge. Can ruin your day. Bob in NC |

Roughing a bowl blank??
I like an Oland tool for roughing or for that matter finish turning a bowl.
It is easy to make and to use. http://aroundthewoods.com/oland.shtml http://aroundthewoods.com/roughing.shtml -- God bless and safe turning Darrell Feltmate Truro, NS Canada http://aroundthewoods.com http://roundopinions.blogspot.com "john" wrote in message ...

I prefer a big heavy scraper. An Oland tool is a smaller scraper. You
can do as most others do and use a big bowl gouge. The thing I don't like about the bowl gouges for roughing, is that they send the shavings right across the top of your pinky finger and hand. Even if the wood is wet, this is very abrasive and is why some turners wear a glove on their left hand. If you do use a scraper, I prefer big heavy ones, kind of like me and my lathe. They just feel better to me, and I am very agressive when I rough out. Also, I always keep the scraper angled slightly down.This helps prevent catches, and if you do have one, it makes it a lot less dramatic. With scrapers, you can also both push and pull with the tool, without having to change positions. If you use a gouge, you generally have the flutes on their side for roughing, and this is actually a scraping cut. How far back the flutes are ground determine how big of a cut you can take. If you are roughing out the inside of the bowl, you start with the flutes up to make the entry cut, and then roll the gouge onto the side for roughing after the cut has begun. robo hippy On Sep 14, 8:52*am, DJ Delorie wrote: "john" writes: BUT, what 'do' I use to rough out a bowl blank?

Since Mr. Feltmate made me an Oland tool addict, I do use them for roughing, but I also use a roughing gouge.. IMHO, the warnings about not using roughing gouges on "bowls" is because of the weakness of the tang part of the tool and the chance of breaking it with a lot of leverage.. Since I am a devout coward, I avoid any turning that involves strain or leverage, so I feel fine with a roughing gouge.. I use a 2" RG for the real grunt work, then a 1" for the finer roughing.. A few things that I should make clear: I don't use a RG to rough hollow, just to rough shape the outside and flatten/true the face.. (what will be the bowl bottom when it's reversed) I keep the tool rest VERY close to the work and NEVER extend the RG more than 1/2" over the rest.. I maintain a steeper cutting angle that I need, so that in case of a catch, the gouge is pushed down my side of the rest, not brought tip-first between the wood and rest... Funny thing happens when the tip goes down.. the handle goes UP and you don't want to be in the way of it.. DAMHIKT I would NOT try to hollow the bowl with a RG... that's what bowl gouges and Oland tools are for.. OTOH, I started doing "faceplate" turning years before I had heard of such a tool as a bowl gouge, and somehow lived through it.. ;-] mac Please remove splinters before emailing |

Your comments would be appreciated. Hi folks, the current move to rename that wide gouge to a SPINDLE ROUGHING GOUGE is for a very good reason. The width of the gouge is NOT meant to go inside the confines of a bowl!! You will get a fatal catch that will ruin your bowl or your self. Bowl work is best left to BOWL GOUGES. You may vary the grind of the Bowl Gouge I use up to a 5/8" Irish ground gouge for hogging off wet wood. Any one suggesting the use of the "SRG" for bowls is at best foolhardy, at worst stupid!

Mac
I looked at the site and the video. This is a nice scraper but it is just a steel bar with a carbide cutter attached as a scraper. The cost is about $10.00 to make. Use a stainless bar and the cost goes up but I doubt that the cut would be any better. My big Oland with the 1/2" cutter lets me use it to cut or scrape but I think this would be a very effective scraper.

Roughing a bowl blank??
The 'Oregon' version of that tool, used by the coastal myrtlewood
turners is called 'the Big Ugly Tool'. To make it, you take a 3/4 inch square bar stock about 30 inches long, and sliver solder a piece of Tantung (don't know what exactly it is, but a piece about 7/8 inch wide, and 2 plus inches long, and about 3/32 thick) onto each end. You wear a glove on your right hand to protect it from the other cutter. The profiles are slightly different, but the Tantung can be sharpened on a standard grinding wheel. You can litterally turn for half a day without having to resharpen. A wonderful tool, equally useful on spindles and bowls. I have seen the daintiest of spindles/finials turned with it, as well as bowls. For finish cuts, use it in a shear angle. I love to rough out spindles with it, but prefer a wider tool for bowls, in the 1 1/4 inch range. The only draw back to the Ci 1 Rougher is that you can't sharpen the cutters, and I am too cheap to spend $22 for a new cutter each time I would wear one out. An excellent tool though. robo hippy On Sep 15, 2:34*pm, "Darrell Feltmate" wrote: Mac I looked at the site and the video.

Sharpening the sides would be a bit harder to do. If one sharpens carbide, use water, the dust of carbide is poisonous. Gerard. http://woodarts4u.com/ |

It was hard enough to make a batch of Oland tool... Also, the carbide tip is what sort of got me interested, since I rough out a lot of ironwood blanks that are rough and irregular shape and a 1/4" Oland is too aggressive and is constantly being sharpened.. I'm thinking that if I was in the States and knew someone that had this tool, I could probably make a bar to hold the tip, but being here, it's easier to just spend the bucks and hope it decreases roughing time.. Sort of like the Termite, it's pricey, but has paid for itself many times over, IMHO.. I could probably do as well with one of Darrell's hook tools, if I wanted to take the time to learn metal working and blacksmith skills, but I'd rather be turning and selling than doing that..
