Must have got the idea from Tom Cooper, The two pre '90s Merlins I own
have the same type of pistons-teflon or a similar material and there
appears to be no wear at all. Water is an adequate lubricant except for the
piston valves. Even when I burned up the cylinders (not uncommon for me!)
on the Hunslet the pistons were OK.
By the way Gary--what are you doing with a Baldwin--I thought you were
into 1/32 Brit stuff--or have you deserted the cause? I feel so lonely out
here.
Where are the rest of you 1/32 limey loco enthusiasts? Come forth and shine!
