I’m beginning prep work for my hardwood floor install and I’ve discovered that the space between my subfloor and base molding isn’t large enough to slip the hardwood under the baseboard molding. I’d like to be able to slide my new hardwood floor UNDER my existing baseboard molding. Years ago I watched a flooring guy use a “self modified” circular saw without the guards on to cut the bottoms off from around doorways. Basically, he rested the bolt that held on the blade on the floor and cut away.

I would use my trusty Japanese saw, but there isn’t enough room to push and pull it under the baseboard to cut off that ¼ inch or so and I really didn't want to modify my one and only circular saw.

I'd rather NOT removing the baseboard molding (1x4 plus ogee molding). Does anyone have any ‘safe’ ideas or a solution (short of doing nothing)?

You would need an undercut saw and someone that knows how to use it safely. You can find some smaller ones at a box store.
