Useful Stuff

Ever wonder what the difference between a lag bolt and a lag screw is? I thought so!

A lag screw works in the same way a regular screw does - the threads on the screw bite into the wood and keep it in place. Like a bolt, it has a head on top, usually a hex.

The threads on a lag bolt do not catch the wood. Instead, you pre-drill a hole, slide the bolt through, and sandwich the bolt with nuts on either side. The threads are only there to hold the nuts in place.

Will and I spent the morning repairing the tongue on our mobile chicken tractor. It was originally made with wood, which broke last season, so we are replacing it with metal. The design is simple: today we cut two metal plates and drilled holes in them. The plates with be welded to a metal tube (the body of the tongue), and we will attach the plates to two-by-fours on the frame of the coop guessed it...lag bolts!

We are about a third of the way through this process. Tools involved so far have been: an impact driver with a ratchet attachment, a hammer, two pairs of channel locks, a monkey wrench, a drill and two different sized bits, a skill saw with the metal-cutting blade attached, the wire brush, and a hand-held grinder. We haven't even gotten to welding yet.

It takes a lot of different bits and pieces to run a successful farm!
