If there is no metal insert and you have pva still wet, why not microwave it? After all, it is a way to season timber.

I did consider varnish, but I preferred the idea of splashing about PVA glue to anything solvent based.
I've been thinking about tool geometries a bit. In past experience, turning wood freehand with anything that has a fairly positive rake is a recipe for disaster, but it might have more success in cutting the MDF if I can keep it under control. The way it's set up at the moment, there should be alot of support to prevent the tool from digging in. The other option might be using some sort of router sled to route the thing round as it spins.
I think i've got too much time to think while waiting for this stuff. I'm also too scared about knocking the thing over and spilling it everywhere if I try get on with something else in the meantime.

Unfortunately there is a metal insert, but that's an idea i'll probably keep in mind for the future.

It sounds a lot of trouble.
I'd try sleeving it with PVC pipe or looking for a roller out of an old printer or typewriter.
You could also try polyester resin (fibreglass stuff) or car body filler to stabilise the surface. It doesn't take long to set although a bit of extra hardener does no harm in the current weather.

That's a good idea.
I did think about sleeving it with PVC pipe but I couldn't find any in the dimensions required, which was a shame.

Good job so farm
