While waiting for this week’s blog to appear, I made several attempts to separate the parts by hand. After three days in the freezer, and varying amounts of force, the pieces finally came apart. You were right, Frank; not the neatest separation, but hey! Success! I’m delighted to be able to use the two R85 supports on my current layout. Again, thanks for taking the time to reply. Cheers, Rick.

I have bought mine on ‘Micro Mark’ and have seen them on eBay also. Happy Railroading.

I have used them with success. Take your time when sawing because the saw blades are super thin and flexible.

You can always replace the ‘lost’ plastic where the saw cut was made with plasticard of a suitable thickness. I would do it that way if it was my problem.

If ordinary polystyrene adhesive has been used, neat separation is almost impossible, as the adhesive contains solvent to melt the pieces together.

If poorly glued, it may possible to separate the parts with a fine modelling knife, or a small screwdriver ground to a chisel point.

Or you can cut the plastic with a fine razor saw, or a fine circular saw blade in a rotary tool.
