Since the stain is done on the outside of the logs, we are able to finally start sealing the gaps between the logs. Many people use the new synthetic chinking, but it's way too pricey & it doesn't breath as well as Portland cement/lime mix. Since we are not using synthetic stuff, the mortar needs something to hold it between the logs. That means we are putting in a nail every 2 - 3" between every row of logs, inside & out. We figure it will be around 17,000 nails. Doing these by hand would take until 2012, so we had a LHBA forum member Rod weld an extension tip onto the framing nailer. This lets the nailer run at full air pressure, but it leave the nails sticking out about 1-7/16", so we'll end up with an approximate 2" chink line. This is the original Paslode tip: Here's the new tip with a 2" piece of gas pipe welded on (Thanks Rod!!) & the final result, a whole lotta nails!
