Been making buffers for the locos this weekend.
Starting with short lengths of 4mm Square section brass rod cut to about 8mm fitted in the 4 jaw self centring chuck then milled the base to 1.5mm.
This is a watch makers mill for making pivots and spigots.
They come in .1mm sizes from .4mm to 2.4mm or at least they're the sizes I have although I have lost the 1.1.mm.
Just run over the section all done in 10 seconds.
4 jaw chuck off. Buffer turned round now mounted in a 1.5mm collet and first part off the excess.
Excess cut off Find the centre with a 2mm ball bur this will give me a good start later.
Now I have turned down the shank.
Next drill out the centre to fit the buffer head I drill only as deep as the base of the buffer.
Now change drill for a .6mm and drill the rest of the way through the shank it has a bit of spit on the drill to prevent the drill sticking and snapping.
Buffers ready for the bolt holes to be put in.
