Ok, before I start this thread, let me just say that I acknowledge my own ignorance, so please no lectures about joining a club or doing research. I plan to do the research before I get started, and I don't even have a chuck yet...planning to purchase this summer. Anyway, I've done a handful of pens (including my most recent with deer antler--a bit trickier, but very cool and came out nice), a t-ball/little league bat, and a few tool handles. I've been getting into turning over the last year, and as everyone says, it is soooo addictive. The next step is working with a chuck on some bowls and other things, but I can't seem to find a good explanation about the difference in a bowl gouge. I've got a wide assortment of roughing and spindle gouges, and I have no problem paying for a nice bowl gouge, but what is the difference?

The easiest way is to have a look at the gouges on Thompsons site.
From L to R. V shape Bowl, U shape Bowl, Spindle Gouge (SG), Detail SG, Shallow Detail SG

This is a short intro on why you may need different bevels (angles) on bowl gouges and spindle gouges

Hope it clears up some of the mystery.

Perhaps easier just to look at the difference. Doug Thompson site is good to see the difference.

Flute design and angle of the bevel are two of the main difference.

Spindle is wider flute. Bowl is narrower flute.

Bowl may be ground back on the sides called a fingernail grind, or Irish grind or Ellsworth grind.

NCPalladin was posting just at the same time. Great minds think alike. LOL.

doug's site is excellent. He also puts the same grind that a large percentage of bowl turners use so If you buy one of his gouges (and they are great) you have a very good starting point to learn with. As far as V vs U it really doesn't make much difference. I have both. I use my V mostly but it's just my style of turning. Other seem to like the U shaped flute.
there are also other shapes like the Super Flute etc but they are all just mild variations of the V or U. Some of the less expensive gouges have odd shaped flutes that don't work as well. The problem is you can't really tell by looking at the magazines. I tried to improve the grind on one for a friend the other day and never did get a really good grind. I made it useable but the flute shape was odd and it made the nose kind of pointy no matter what I did.

So a roughing gouge is a spindle gouge then?

 

[john lucas]

No I would not call a roughing gouge a spindle gouge. Although it does depend on what you call a roughing gouge. Usually a roughing gouge has a deep U shape. Spindle gouges tend to be somewhat flat. I have seen what I would call a spindle gouge labled as a rough out gouge.

Hope I'm not stating the obvious, but roughing gouge is more properly referred to as a spindle roughing gouge. Should not be used on bowls, ever. Unless you really, and I mean really know what you're doing and the its still not a good idea.

 

[john lucas]

Here's why it should be used on spindles only.

Wow, lots of good info, thanks a lot guys

A bowl gouge is more heavy duty than a spindle gouge. You should not use a spindle gouge or roughing gouge on a bowl . The shank of the bowl gouge going into the handle is larger and can take more stress.
