These are no big deal but they work for me and are cheap and easy.
Popsicle sticks are .07" thick. Lay one on either side of a brace and use a small block or a file or anything you like to get consistent .07" ends. Takes about a minute.
You can purchase small whip nozzles at hobby stores, and if you trim the top of a glue bottle nozzle to the right diameter, the whip will fit inside and a drop of CA will seal her up. Then cut the whip to the length that lets out the size stream of glue you want. Very precise, keeps things very clean.
The go-bar deck is dowels, fitted in to larger dowels which are in turn drilled to the size of the smaller dowel, and inserted with a spring of sufficient tension. I keep 2 lengths of the smaller dowels around, put stick-on cork on their feet, and away we go. Works well for me.
