Here's how I measured for a good placement. I measured approximately 6" down from the end plate, and then measured horizontally across (outside of leg - outside of leg)for the correct length. The mounting hole on the rear of the BB is located 3" down from the top of the BB.
This insures that the plugs going into the top of the BB will not interfere with the end plate tuning.
If any of you that own double-necks would make this measurement on your guitars and send me the make/model/ and inches across (to the nearest 1/4")it would be greatly appreciated. I'm try to come up with a way to ship these as cheaply as possible.
The single neck version seems like it would fit in a "priority mail" envelope and could be sent anyway in the U.S. for $4.95. The D-10 length is going to be slightly longer and I don't know if it can fit in the same packaging.
For any of you that want one of these, and don't have the facilities to cut/bend steel, I'm trying to figure out how to get it to you cheaply as possible. I'm not interested in profiting from this, and any money over shipping and basic supplies would be donated to the forum.
The most expensive part is the thumb screw. If you do not need to disassemble the mount from the BB, then a simple 8-32 x 3/8" machine screw could be used and save $3-4 from the total cost! I do have a clip-on version coming up, but don't know what's involved in cost yet.
I'm trying to keep the whole deal around $10 shipped for the single-neck size.......
Always remember you're unique..... Just like everyone else
