Hi John what is the purpose of the PVA mix? I’ve not seen that technique before, is it to help the paint adhere to the plastic?

 

Thanks

Yes. It is a technique I discovered by accident during the 1990s, probably after ballasting some track. I now use it a lot as it is cheap and reversible if it goes wrong. 50:50 PVA base as the primer then paint with a fairly dry coat of simple watercolour paint. I also use it for weathering rolling stock. 

Short intro video on YouTube - 

The pin in the leg method works for me . 

I tend to use 10 thou guitar string. and a 0.4 mm hole in the baseboard.

Ah interesting thanks, I suppose if you wanted you could easily strip everything off with warm water and a tooth brush - which makes it tempting to me haha

 

Thanks

Yes, fully removable as per the Hornby Hull & Barnsley van in the short YT video. Painted a mucky grey based on a memory/ assumption then I found out they weren’t grey. That one is now scrubbed clean awaiting another go.
