randy this dowell is 3/4 in. and it does ok with a top E acoustic guitar string .052 or .054 thickness. i use 1in. dowells also and put bass guitar strings on them. guage- .065-D string and .085-A string so the 1 in. dowell is ok if you make it go all the way through the box. so you should be ok with a 1 in. thick dowell.
