Hi there Paul
I tried to find a suitable toy car that I could cannibalise for quite a few weeks, but no luck
Made a few tentative attempts at making my own, but without my lathe, it was difficult
Tried several thicknesses of ply, but not good enough, tried brass, still no good tried a few thicknesses of Ali. not bad, then realised I had run out of Ali!
I`ve ended up reserrecting a scrapper and decided it`ll have to do!
It`s a pitiful story I know
Bob
