Floorboard Cutting - what a chore!

[DNS1]

What ever circular saw you use, make sure the depth setting knob stays in place tight while in use. Used a cheap one a while back and the vibrations caused the saw to sink while in use... Before I knew it I was cutting 10mm below the boards... Miraculously didn't do any damage!

I use a Makita 18volt lithium ion cordless circular saw, very powerful and well made tool. I find it the best and fastest tool for cutting through the tongue then across the board. Just set the depth accordingly and avoid nails if possible!!! Springing the board a little is a good idea, also have used a pipe detector in suspect areas, though no doubt I am due a cut pipe at some stage. I keep some self sealing tape in the van until the plumbers gets there!!!!

Springing the board prior to cutting is a must in my opinion, just not worth the risk.
All these years and I still get a little nervy when cutting boards.

I've been using the 10.8v makita circular saw our about 6 months now. It's great. I wouldn't part with it. Especially useful when cutting a floorboard where the nails are banged in the joist quite tightly together as it has a narrower blade to get between them.
