Get's a bit heated at my house also during even simple glue ups, I
think a check list on the wall just before being done would help too.
I always forget to check square in one direction of another too.

David Marks uses the plastic resin glue a great deal in his woodworks
show for the up to 1 hour open time. Although you have to leave the
parts in the clamps for 24 hours, I am going to buy some for the extra
peace of mind tomorrow while I get a couple of pipe unions to extend
some pipe clamps for a curio carase I am having trouble gluing up.
