I was working away today and thought I'd pass on a little photo essay.
I regularly have to come up with tuning machines in non standard configurations. Here is a set for a 5 x 5 symmetric set for a ten string mandola (fan-dola) that I'm working on today. I've seen custom made Waverly machines in this configuration on an instrument, and a set for sale in the classifieds a while back. No matter who I've asked, or how many times I've called them up, every time they told me they don't exist and they won't make them for me. I've also heard that Schaller makes a European set in ten string configuration, but haven't been able to find them here.
I usually try to get Nicolo Alessi to custom build up a set for me, but that takes a bit of time to get them here and some patience while they are being made. Some days either I or the customer doesn't have the extra time, so here is one way that I work around it.
Most of the sub $80 tuning machines are pretty similar in design and function; they each have a tiny feature or two that separates them from the pack, but not much. Schallers have been my favorite for modifying, mainly because they are well tested and everything comes apart from the baseplate. They also come in standard and reverse gearing. That allows me a huge range of options, especially if I dissassemble them and flip the plates left and right. I've modified dozens of sets of Schallers like this over the years.
I generally prefer the F style machines, because their button shafts are smooth, unlike the ornate "a" style. That allows me to cut the lengths and not interrupt the design. You'll also notice that I changed out the buttons from the faux pearl to black.
For this set, I start with two sets, cut them up, and morph the two. Usually three sets get me two ten string sets. These were cut and butted together at the third screw hole from the top. If you look hard, you'll see a faint line, but the results are pretty good and can be done on the spot in a few hours with stock machines. Filing both halves at the same time in the vise makes for a pretty clean joint. Even if you are off a degree or two, it is balanced between both halves.
