Has anyone had any issues using .26 spaceballs in 3/8 deep groves ? If leaving the recommended 5/32 that leaves the panel in 7/32...any splitting of the back side of the grove and especially if the panel goes in a little tighter (say 1/8 gap instead of 5/32 ?)....I'm using them for the first time in a panel bar front that cannot be fixed easily if something was to fail. The panels are only 8 inches wide each, so no issues with too much movement. I'm using Freeborn cutters and their standard is 3/8 grove, and really do not want to go deeper just for the spaceballs....appreciate any feedback ....
