Do you know the difference in shape/grind of the TT spindle gouges?
Unfortunately there are not specific pictures on the website. I tried to contact them a couple of weeks ago, but didn't get any answer.

I'm not really sure what you're asking.
As per the Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register, he recommends a 40 degree angle on both the spindle & detail gouges.
Is there a style of grind you're specifically looking for?
Here is a photo of my 1/2" detail gouge (spindle gouge is sharpened the same)

Doug Thompson has a section on sharpening on his web site which shows  the settings he uses with varigrind for sharpening.  He ships with a 40 degree nose and a "conventional" shape --  that is, neither pointy nor with swept back wings.

His prior web site indicated he uses the flute at 50% of diameter, so it can be used to drill into end grain.

My observation is that the sides of the flutes on the thompson spindle gouges are thicker than on some other brands of spindle gouges in the tool bucket.

My other observation is that the sharpening out of the tube is consistent.  Same thing every time.

I still have the freedom to grind them any way I want them.

I don't know if this is what you are asking but here is a pic of his gouges.  Two left are bowl, then spindle, then detail spindle, then shallow detail.
The spindle depth is 50% of diameter and the shallow detail is only 20% of diameter.  I did not find the detail but it would be somewhere between the two. The more shallow the depth in the diameter the more steel is left underneath.
Here is the link for the shallow detail gouge.

Thanks guys.
On the website I see there are spindle gouges, deep flute spindle gouges, shallow detail gouges and detail gouges.

This is the problem: as spindle gouges I only had the chance to used  a cheap (also not thick) 5/8 spindle gouge and a decent Crown 1/2 detail spindle gouge (I think it can be classified as shallow flute) and a cheap small 1/4 spindle gouge.
I do almost all my work with the skews, scrapers and bowl gouges and I have been not happy with my spindle gouges, except for the smaller one after I regrinded with a more pointy nose, but sometimes I feel the need of a larger one.
I also tried to regrind the the larger one, but still didn't like it. I was able to sold them and now I was looking for one that is more comfortable for me.
I found out that the cheap one was too large for me and also didn't like the too rounded point. The detail spindle gouge I think it is too limited for how I want to use it.
So essentially I am looking for a spindle gouge that is like the smaller one that I have with a more pointy nose.

Let's see if I am able to load some pictures.
The first picture it is a gouge like the detail spindle gouge I had.
The second pictures is a gouge like the large regular spindle gouge I had.
The third picture is a gouge like I would like.
Now I assume I can exclude the shallow detail gouge from the TT site and I also assume that what I am looking for is something with deep flute.

First of all, let's not get too confused. Anyone who sells a spindle gouge can call it whatever they want to. Many different names can point to the same thing.

The grind, not to sound like a broken record but if it's your gouge, grind it how ever you want to. I could easily grind my gouge I posted to the same grind as the one you like, which appears to be a straight pencil grind. The first two photos look to have a slight fingernail profile. IMO the grind is far more important than the flute depth and I never concern myself with how a gouge is sharpened when purchased.
If you are used to using a skew, I might lean toward the detail or shallow detail gouges, or any of those with less than 50% flute.

Yep, that's why it is confusing. I understood that a detail spindle gouge from a manufacturer can be completely different than a detail spindle gouge from another manufacturer. The best thing to do is seeing physically, but there is no chance.

Thanks for the pic.
I know that I can regrind them, but just want to be sure what I am getting if I spend that money.

If you need/want pictures of other gouges or grinds, I'm sure myself or others here can post pics for you.

Can't any spindle gouge be shaped to a more rounded or a more pointed tip, regardless of the thickness?  Somewhere I thought I read a "thinner" spindle gouge allowed narrower V groves and finer detail.  And a thicker spindle gouge should be useable farther off the tool rest (more reach).  Other than those points I'm not sure why spindle gouges would be offered in different thicknesses.

Yes,

Another reason for the different "thickness" of the flute as you referred to it, is really a byproduct of the shape.
A shallow flute (detail) gouge with a shallow curve in the flute cuts differently than a standard (beyond 50% of the diameter) gouge with a deep curve in the flute.
Detail gouges are also better at getting the tip of the tool into tight areas since the point is not in the center of the shaft, the smaller wings do not interfere nearly as much.

Doug has been very busy getting ready for the AAW symposium.  If you send him an email he WILL answer back since he might not be at home and on the road.

Good thing with emails is they can be answered anywhere.

That's what I did 2 weeks ago.
