This tappet from my 1927 Model 18 has worn beyond further use and my spare tappets look even worse! For someone with the right tools it should not be too difficult to reproduce the part (see below) but I don't have a lathe or a milling cutter. Who has a few decent spare tappets laying around and is willing to sell?
"Tappets are not hard to make with a lathe and a ball ended milling cutter to make the spherical socket for the push rod end. I made some several years ago and had the stems ground to size after hardening. The tappet guide can be bored and sleeved back to original size or can be opened out and the new tappet given an oversized stem to suit. The tappet guides are not hardened."
