Ripping header

[Crankycarpenter58]

Imagine your rail on edge.
Going to rip a flat roof garage header (top edge) to accommodate slope.
No place to clamp.
Was thinking of blocks to hold rail(s) in place. Moving to new position each time.
Or screw? Rail to lumber. (If screwing, is there a "better" place on the profile of rail to drill and lightly countersink for screws?)

Ok so if im seeing this right you want to put a bevel cut on the top of the header so the roof slope will plane through? That'd mean you need to mount the rail on its edge. The rails already have a hole drilled on either end, it's hoe i attach my rails to the sidewall of my trailer. No clue if putting a screw there would interfere with the saw operation.

My choice would be to drill a small hole and then drive a trim head screw through the clamping profile that sticks up. Id think you wouldn't have to countersink it and could just remove it afterwards with no harm done. It's also kind of meaty.

Screwed to ceiling using existing holes at each end of rail. In your situation you could screw each end too and at mid point clamp a supporting block under/along the rail edge.

If you have to move the rail along the header, perhaps make a reference line with a chalk line.
