Arch Question

[TomSkippy]

Couldn’t find anything on Google, Technique question: is there any way to attach bricks/plates to the inside of arch pieces? Specifically I’m wondering about the groove on the other side of this piece:

It depends on the exact part number of the arch.  The older ones especially, yes, you can attach a stud into the grove under the arch.  Examples using various arch elements from various builders: 1, 2, 3, 4.  Some of the new molds for arches have thinned out the webs such that you can't get a stud to stick anymore.  There was some really good analysis of the differences in some of the blogs when the changes first came out.  I don't know if the web thinning has happened to every arch mold.  If I had any of that part number, I'd try it out and let you know, but I can't find any in my inventory!

On the one I tried, there was almost no clutch toward the top of the arch.  At the bottom of the arch, the interior wall makes the depth too shallow.  Right in the middle I could easily put a stud in and it stayed without issue. But you could not do 'all around the arch' techniques given by @mrcp6d.

It's an official TLG technique that goes all the way back to 1990 (6376) at least. But alas, many of the arches have been changed in design since then

I did not know that!  Thanks for the info.

Thanks for the replies! I bought a couple of aged arches on BrickLink!

If you use inverted 1x2 curve tiles they work quite well. 
I used them as below for a Factions entry, adding a stud to the underside of arches is often a nice touch but as has been mentioned - it doesn't work for every arch piece and going from brick to brick the clutch can differ too:
