All,
Blaenau North is now wired, ballasted and operating well. I am now starting on the scenery.
At the rear will be a plaster of paris stone effect wall (Bragdon enterprises - thanks Tom).
However I need to trim the wall down to about 3" high and if I use the full depth of the mould I can get 2 lengths of this height out of it.
I just wondered if anyone knows how to cut plaster of paris - I was going to use a small saw but it occurs to me there might be a better way - slitting disc/cheesewire ?
Any suggested would be much appreciated
Thanks
Bob Berry
Glad you've taken the plunge with the moulds, Bob.
Before getting to the cutting stage I blanked out part of the mould to avoid wasting plaster using cling film covered foamboard.
I then cut the resultant castings with a junior hacksaw.
Tom,
Its good stuff and I'm happy with the moulds and the process - rehearsed it a few times including the colouring process.
Yes I could do that but I like the idea of getting 2 separate 3" walls out of one pour.
Just experimented with a hacksaw blade and seems to work quite well.
Bob
How about making a thin plastikard divider that you can press into the wet plaster before it sets? You could grease it with vaseline or silicone spray so it does not stick.
Yes, on reflection it is going to be easier to put a divider in than trying to cut the walling once it has dried.
I am going to try this option first

Rather than greasing the plasticard you could wrap it on both sides with cling film - works for jellies!

Or use a strip of thin PTFE rather than Plastikard, though it may just be OK to use 'naked' Plastikard, a simple enough idea to test I would have thought.
