Simplify set up with a homemade adjustable bridge.

There isn't much about building a cbg that I find tedious but set up can be trying.  I like a fairly low action on fretted cbgs and with that comes the requirement to refine bridge height and usually the nut (slots or overall height).

I was forever shimming or remaking bridge saddles trying to get the right height until I came up with this idea for an adjustable bridge.  

The bridge is made of two fine thread, brass machine screws to which a brass rod has been soldered. Nuts are spun onto the screws and the projecting threads are set into a drilled piece of wood that acts as a foot. Height is adjusted at either end of the bridge by putting an 8 mil wrench on the nuts. Like most cbg bridges this one is not glued in place so that you can make some adjustments for intonation. Oh and for nut adjustment I don't spend a lot of time filing slots I make them out of brass threaded rod (softer than steel threaded rod) and simply file the backside to get the height right.

Awesome idea! Can I ask if soldering the rod to the screws created any problems for height adjustment as the sides move independently and I would guess it might break the solder joint. Other than that I am going to attempt this myself! Where do you get your brass parts?

Good idea! I might have to give this a try.

This is great and just in time too. I was thinking about making one like this, so thanks.

Nice how-to John ;-)

Richey - I think the epoxy idea may also provide a cleaner finish at least for those who solder like I do.

In an effort to acknowledge the fantastic adjustable bridge pic someone just posted I seem to have deleted the comment.  Damn.  Anyway excellent work. Sorry about the other comment as well -  I am a wrecking ball...
