In the near future I'll also need to scribe some other boards against a wonky wall.
Compass and a hand saw would be my recommendation. I normally use a handsaw to make a scribe cut (unless speed is of the essence) as it's much easier to cut accurately to the waste side of the line. Back when I regularly taught apprentices I wouldn't let them near a jigsaw for a scribe cut until the could do it near perfectly with a hand saw.
When I have time I'll write up my process for scribing and post it.
Need to trim down a bit of height from some end boards. What's the cleanest way to do this? I have some pull saws, though the blades need replacing to get the best results. Ican get a very clean line but rarely get a straight one on longer distances. I have a dewalt circular saw with a ripping blade I use for quickly chopping through thicker bits but again, a straight line over a long distance seems ambitious for my abilities.
In the near future I'll also need to scribe some other boards against a wonky wall.
What are my options:
1.
Get a finer blade for the circular saw like this:

and a guide rail like this:

The floor I'm scribing to is pretty flat - with 5mm tolerance I'd say. The flooring I'm going to put down around is a layer of underlay, then 7mm cork so would cover up any imperfections at the bottom.
