Composite mitered stair treads. Screw the miter?

I understand the risks with permanently joining long composite boards due to expansion/contraction.

What is your preferred method for keeping stair tread miters together when doing a border on treads? (Treads 3-4' wide)

Also any tricks for keeping them even on the flat? Seems like a composite biscuit would do wonders but I haven't seen any???

I've also been trying to avoid this type of tread detail as it's a major slowdown. I like the look but this year I did all my stairs with and extended stringer fascia and butted the treads into them or did a 1.5" return detail so I didn't have to add blocking. We'll see how those are holding up next year.
No doubt that is faster. But aren't you begging for a crappy looking job down the line after the freeze thaw cycle takes its toll on that facia board? Seems like it could be disastrous leaving that open channel for water/snow/ice debris...

Nope. I don't do something just because it's faster. I put 1/4" pt spacers along the stringer before mounting the fascia and then have a 3/16" gap between the tread and the fascia. It's no more likely to look bad than any other gap on my deck. I also don't use the 1/2" fascia. It's full deck boards for me. Here's a garapa one I just did with that detail.
Glad I asked! :thumbup:

Spencer, Be sure to post as soon as you knock your cordless into the pond.
Will do. It is bound to happen. Though I am more concerned about keeping myself out of the water. Its rather cold this time of year. By the way, its a ski lake.

My buddy is working on a hardscape about a hundred yards away. I told them that if they hear a splash to come save me. The other day I dropped a good size board from the top that made a decent splash and they didn't even look up. :sad: I might not make it out of this one alive.

I am going to be ticked if I drop one of my new 20v dewalts in there.
