Spreader clamps: seriously need some of those in my life! The reversible bit is awesome

I empathise with the nailing: we tried nailing one of the boards back on (that we'd removed off the bottom of the playhouse to put the tunnel hole in) but it was too flexible and bounced all over the place so I gave up and screwed it in with my modified drill Did the job and still fine, but wouldn't want to do it too often as we split a few (unimportant) things screwing stuff in, but that could be my electric screwdriver inexperience
