Options for inside corners on lap siding

[drnickriviera]

Doing a small porch and am brainstorming some ways to do the lap siding. I know i can do a typical 5/4 X 5/4 or 5/4 X 4 trim piece, but was also considering no corner boards. I'll probably be using either LP smartside or Hardi. My first thought would be to do a woven corner, but it won't work like it does on an outside corner. I'd have to trim off a little rectangle where the upper piece overlaps the piece below it. Doable, but time consuming. Other options are to have one straight caulk joint with no weaving and angle cut just 1 side. or miter the ends. Am i making any sense?


Another unrelated question. This porch is the front entryway. The front door is set in from the front face of the house by about 3'. So the ceiling joist are cantilevered that 3'. They built a double 2x8 header to support the cantilevered section, but they used no jack studs. They just toenailed the header to the king studs. The span is a little less than 8'. I'm going to rebuild the header and put some jack studs in, but was just wondering how much cantilever you can have with no or little support? Their method seems to have held up for 60 years. I can see no evidence of sagging.

Hardiplank doesn't miter well, way more trouble than it's worth. Woven sort of works, but a very careful instillation will be acceptable at best. They also make metal exterior corners for hardiplank that work well, but they look like metal corners stuck on hardiplank. To me, it makes sense to work within the limits of the material you're using, Hardiplank works with corner boards, so that's how I generally install it. On inside corners I use 3/4 x 3/4 and but to it, looks fine. I also blind nail Hardiplank with roofing nails, the bigger head has a little more holding power.

The cantilevered porch depend on the material size and what load it takes, so I can't help you without a little more information. The beam is an easy fix, get two header hangers and nail them on, then side over them.

I like the 3/4 x 3/4 look that greenman suggested.

I think the no corner board just looks so clean.

The header was just a curiosity. I had to rip it out anyways as both corners were gone from termite damage. I only have access to one side. Brick veneer on the other.

I never really though about using a roofing coil nailer. I have a coil siding nailer, but you are right, the bigger head would be nice as it is so easy to overdrive the nails
