Go Bar Jig

Said to have come from Japan via the US, this is a wonderfully simple and convenient way of gluing complex arrangements such as struts and braces. The springy rods (colour coded according to length) push up against the roof of the jig and down against the part to be glued.

No actual clamps are needed, allowing good access for cleaning up any surplus glue.

Here German spruce struts are being attached to a Malaysian Blackwood New World guitar back.
