Shim brass is basically just very, very thin brass sheet. Modellers in the old days seemed to make pretty much anything from it, and I was always impressed by the versatility of this wonderful material.
Of course, I aquired some, and have hardly ever found a use for it.
Until I came to fit the backhead to Ghillie.
The whitemetal backhead is fitted to a U-shaped lump of the same material. Said U-shape is to be cut back so the backhead just clears the rear fixing screw. Trouble is, when you do tha, you are still left with a gap between the back of the backhead casting, and the cab back.
No problem, a strip of shim brass, soldered to the backhead with some 100 degree solder (a process that sounds simpler than it turned out to be) covers this, and makes the whole assembly look much better.
And I've still got loads of the stuff left - probably a lifetimes supply!
