specialty deck tools
I've been having fun shopping for specialty tools that will make our deck building smoother. So far I've bought:
-post hole auger for a tractor (found a used one for $300: not much more than the rental of a manual one for a weekend)
-Metal connector nailer (got a reconditioned Bostich on ebay for $150)
Has anyone used these "joist jaws"? They seem handy, but 50 bucks seems a bit much for something so simple.
And what about levels? I've found string levels (seems like the string would sag) post levels (we'll have a total of 51 posts between the frame, pergola, and railing), plus an 8-foot option (the longest one we currently own is only 2 feet). Which are the most useful? Do I need them all?
Batter boards: are home-made ones good enough? Any tips for your favorite design?
Any other tools you'd recommend? We've got the basic assortment of saws, drills, and nail guns that we need.
