Ok so trying the thimble idea.
I sewed one of the trigger board directly onto the thimble to begin test fitting in multiple gloves.
I wanted to sew onto the thimble instead of having it sewn onto the glove liner to try to make putting these on as painless as possible.
The result, the "thimble trigger" widened my finger tips just a tad bit too much to where you could definitely tell something was under my glove(could see the outline of the trigger).
When i placed them inside my rubber chemical gloves, it was not as noticeable at all, but that was also without wearing a glove liner as well. Also putting them on was kind of a pain as it was rubber moving past rubber and it tended to get caught at times.
So, next up, ill try sewing the trigger boards directly to the glove liner to keep putting them on a little bit easier and also to keep the "finger bulge" down to a minimal.
I inspected the board that the trigger sits on to see if there was a way for me to extend just the button itself, but it just doesn't seem possible.
