Well my first build went well, a pair of Diddly Bo's. (pictures to come soon).
I got the tuner's for free from a lutier who didn't mind thinning out his junk drawer for a good cause, and I got the cigar boxes for free from the owner of the tobacco store I patronize frequently.
They are face mount necks (similar to Uncle Crow's design) which makes it easy to open the box while still strung and staying in tune (I keep my slides inside when not playing).
The first time I tuned them up I had an annoying buzz, I thought it was possibly the break angle over the nut being less than 5 deg. But it turned out it was just the tuning knob was loose. A little tightening of the screw and all was well.
They are electrified, each has a piezo disk and 1/4" jack with no volume/tone knobs. For now the piezos are just taped in place with blue painter's tape, but I will be experimenting with placement and sandwiching them inside of something to see if i can reduce the feedback.
I used 1/8 in rivets with the nail popped out for grommets in the tail to anchor the strings and that worked fabulously.
I have already promised to build a CBG for the owner of the tobacco shop, a nice little bribe to get more cigar boxes for free.
