Of Mice and Mountain MenPreviously, we laid out where the retainer walls will be and squared up the corners. Now we’re ready to start digging for the ground-level timbers.

Fasteners

But first: how will we fasten things in place?

Beveled pin end

I’m using two types of fasteners. One is 1/2” rebar that I cut into 12-inch lengths. I bevel one end a bit, just to help it pass through the hole in the timber (drilled with a 1/2” spade bit) without snagging on the wood. Unless your ground is hard as rock there is no need to grind the pin to a point. Use these pins to fasten the timber in place on the ground.

HeadLok Screws

For timber-to-timber fastening, I’m using HeadLok timber framing screws. You can use a variety of fasteners, from spikes to lag bolts to deck screws. I researched them all. I’ve used decking screws before and found that they are a bit light-weight for this use. And expensive. I’ve used lag bolts and found they hold forever, but the heads have to be counter-bored into the timbers as well as drilling a pilot hole. Extra work, and the bolts are expensive. Timber spikes are the cheapest, but the timbers will jump around as you drive the spikes in, ruining your careful placement to get a good, plumb wall.
