Building a Building a Fixed Gear track style bike from an Orange P7 Mtb Frame

Could have just stuck to it being an MTB and have a fixed, rigid mtb? That's what I use and it gives me a much more versatile bike. I can ride, on road or off, and I prefer the ride position and handling of an mtb to a track frame. Especially if you put short forks on it.

Chainline was no problem as all, I am getting 43mm from an XT front disc hub and bolt on cog combined with the chainring being on the left hand of the spider rather than the outside. And that is on a 135 OLN frame.
