using go bars for neck and tail block glue up! Clamp time?

I'm sure all the cool kids thought of this ages ago, but as a newbie builder it occurred to me I could use shorter go-bar rods to help clamp the neck and tail blocks during glue up. Here I have the mold elevated so I can get some extra clamps on the edge, top side of guitar is facing up, string is to check centerline...
so do I really need to let this sit for 12 hours if I'm using fish glue?

yes overnight is fine but what is the side like on the block the gobars are not doing anything it is the side to the block so the sides are thinner and they need the clamp pressure more than the block

Hi John,
Yes, the gobars are just pressing against the mold, squeezing the block to the sides in those areas. Where the sides extend above/below the mold I have clamps in place to squeeze the sides firmly against the block and insure a good joint. The gobars seem to help in two ways:
1. It was a quick and easy way to hold the block in place while I positioned clamps and cauls.
2. It applies pressure to the center of the block - an area I could not clamp without removing the body from the mold. I realize your videos show taking the body out of the mold for this step, but after rehearsing it and thinking about it, this seemed easier.
Cheers,
Mark
