Which gouge should I use?

[SceneryMaker]

I turned a base for a table today and wasn't careful enough about keeping the segmented rings concentric. I had enough runout that my 5/8" bowl gouge was kicking and bumping with every revolution and it really beat me up. I eventually got it round and then to shape but it was not fun.

Would a heavier tool like a big roughing gouge work on a segmented piece? With no end grain, I would think it might work but I don't have one to try.

Would something else work better?

Never tried a spindle roughing gouge since the grain is perpendicular to what it is normally used for but you could try it and report your findings.

I generally will start with a bowl gouge, but will sometimes switch to a scraper or Easy Rougher, particularly for the interior.

Well, not really.  The edge should cut across and peel down if you're using the tool properly.  I like broad sweep types, because I can get some wide shavings off the piece.  Since I'm working downhill, broad means a generous amount of wood is being removed.  Swing the tool into the cut, using your off hand as a pivot, and simultaneously drop the handle to provide a bit of skew to the leading edge before you advance the tool while holding it firmly to the rest.  If your shape is not round after the first swing, make a second to get the corners off enough to keep from whacking the heel of the tool before proceeding.

The usual rules apply,  Minimize overhang and maximize mechanical advantage.

I recently made a tall urn and while it takes some additional time I glue up each ring one at a time. This urn had 19 rings but I made it in 3 sections. So it was about an extra week.

One of the problems with a huge glue up is everything can shift so you can glue 2 rings at a time. Ex, glue 1-2, 3-4, etc. Then 1-2 to 3-4, etc. this way you can use one of the rings as a guide to center the other ring.

As for rounding the urn. I get my sharp 5/8 bowl gouge turn the speed up to around 1000 rpm or so and present the gouge at 90 degrees. I barely touch the wood just enough to take off the tips of the segments. Once the tips are gone you can start rounding it more aggressively.

I hope this helps a bit.
