I use rubber precision pipes (a special kind of
rubberhose).
Deoes anyone know a UK supplier of small-ish quantities (I do not want to
buy 100m of the stuff ;-)).
Diameters for the 9144 are inside 6/16 outside 7/16
inch.
Do you mean that? The roller is a lot larger than that. OK, it would
stretch onto the hub, but surely if the inisde diameter is 3/8" (6/16")
and the outside is 7/12", them the wall thicknerss is only 1/32". And
the old tyre looks a lot thicker than that.
I glue the with polypurethane glue and grind to the
right size using
sandpaper 150 (3M wet or dry)
I asume you run the motor off a bench supply and carefully hold the
abrasive againsit it.
I finish the capstands with a sandpaper 400 so the
surface is smooth.
For the HP85 / 9825 /9835 tapedrives I use a 6.5mm citroen hydraulic rubber.
Is that what I would call a 'sleeve seal'? That is the little rubber seal
you put ove the enf of the pipe before screwing the union down? IIRC they
come in 3 sizes, I assume you need the largest one.
