Hello,

I have a circular room where I need to install baseboards. It's an old apartment, so I'm going to construct a baseboard that matches the other solid baseboards in the apartment.

I've glued a grooved MDF baseboard as a foundation. It's designed for curved walls and fits the wall nicely.

On top of the MDF baseboard, I will glue various types of moldings and dowels to finally achieve a nice "old" baseboard.

At the bottom, I want to glue/nail a narrow pine baseboard that is 8 mm thick and 40 mm high. The baseboard is about 3 meters long.

It can be forced against the wall, but there is considerable tension in it even if I secure it using weights.

I'm not sure if I dare to glue it under pressure. It might have so much tension that it pulls the MDF baseboard off...

Is there a way to soften the pine baseboard, for example by soaking?
 
Yes, but it takes time with soaking. My grandfather tied litser to the dock when he was preparing the boat and needed to bend lister. Basning is faster. http://sv.wikipedia.org/wiki/Basning

Yes, but it's difficult to bend 3 m long molding at home, isn't it?
 
If you cut some notches (not all the way through) on the back, the tensions should release. The gaps that become visible at the top of the strip can be covered with a bit of latex before painting.

It should probably be a series of notches across the entire surface that is bent, otherwise there is a risk that it might break when you bend it.

There are a few different solutions to the problem.
One could be to cut grooves on the backside with a circular saw or similar.

Basning is, as mentioned, another solution.

You have somewhat thicker material, but it should be possible to do like when making svepaskar. Run for a little longer, I would guess 15-30 minutes. It should be possible to build from an old downpipe. I seem to recall that I made the opening ring on my kayak in one of those.
 
Downpipes are excellent to use for one or a couple of strips. Just don't run it for too long, it's not good, wood gets damaged then. Some experimentation may be necessary to determine how long to steam.

If you download the following handbook and look at page 18, you can read about steaming in boatbuilding.
