The gaps at the top between each roof truss is what I'm asking about. This is a workshop with insulated walls and ceiling. There is an exhaust fan in the loft and window at the other end in the loft. Should I fill the gaps (foam spray or rock wool, etc) or leave them to breath? There won't be a ceiling under the overhangs where these gaps are. You can reach through the gaps and feel the insulation on the other side (interior of shop)
It's point #8 found here on the home build site, among several dozen other hand tools, mostly rhyolite, Person County, NC. I have another one similar but it's a Kirk. Just can't see the work marks on this material after it gets this heavy patina. Think it's a Guilford?
Are my eyes playing tricks on me or is this reduction flake worked on the long edge and even a little bit up near the point? That’s what I am seeing. It almost looks like they tried to make it serrated.
New install in a workshop, I've got a question about getting the stove pipe apart when it comes time to sweep it with a brush. The stove pipe is double wall and uses a twist system to snap the pieces together and then a compression collar to secure them. The 2nd pic shows the pieces I have to be installed by the framers through the roof later this week. My question is, can I un-lock the pipes at the 12" section in the loft (pic 3) and push the pipes up just a little to access the inside with a brush, or will it cause a future leak if I push the pipe up through the roof just a bit and then let it back down? The only other way I can think of would be to get on the roof and remove the cap. Not very desirable to me. Also, I know the double wall all the way down to the stove is overkill, I wanted it as close to wall as possible.
