Barrie,
I used "O" rings as the piston rod seal in my Filer and Stowell and they ha=
ve lasted very well. One needs to polish the rod with a cloth wheel and Je=
welers rouge or something similar to make sure it is slick as possible. Yo=
u will need to make a wee boring tool to cut the internal grooves in the cy=
linder heads. I made mine from a 3/32" Allen=AE wrench with a piece of tun=
gsten carbide silver soldered crossways on the tip. Works perfectly it doe=
s so I say GO FOR IT Mate!
Jesse the Tennessee redneck and proud of it.
I am currently refurbishing a 5" Duchess. The engine has seen quite a bit o=
f use, having had several owners the last of whom dumped it in a barn! I am=
currently working on the cylinders which have rusted quite badly.
The piston rod glands are fairly conventional stuffing boxes but each gland=
has four 10ba studs with a pair of locking nuts on each stud. This arrange=
ment is very difficult to adjust on the outside cylinders and virtually imp=
ossible on the inside cylinders (It is a four cylinder engine). I am contem=
plating modifying the arrangement and replacing the stuffing boxes with O =
rings. Similarly with the piston valve rods. Whilst I have used O rings wit=
h considerable success on piston valve rods I have never tried them as a pi=
ston rod seal.=20
Any thoughts gents?
