2. belt - Abene says they used both V and flat belts on this machine -
mine
has triple V belts to drive the spindle and a single flat belt to drive
the
table gearbox - the flat belt sheaves, measured at the crown are 88 mm
(about 3.5 inches) and 51 mm (about 2 inches) - I'm thinking of changing
to
a J series micro-V belt - any thoughts on this idea? I guess I could
change
to a V belt - it only needs to hold 2 HP after all.
3 the original flat belt is 40 inches X 1 inch - does that size seem
standard? The belt in there now is a Gates SpeedFlex, which is long
obsolete. Any thoughts other than using a microV belt?

From SKF's site, the seal is a CR 17X35X10 CRSA1 R, US stock no.6712.
For the belt, I'd download Gates' belt sizing app. The micro v sounds
more likely to fit in the same space as the flat belt than a standard
V.

Thanks, I'd forgotten about SKF, I'll see if that seal is easy to get -
right now I've machined a ring and used an oil pump seal that is common
as for the belt - I really really REALLY want to forever solve the problem
of the belt slipping off the sheaves - I don't mind it slipping - in fact,
that is a safety feature - so far, I'm thinking of using the Gates micro-V
belt (specifically 400J10) and I am thinking I'll make new sheaves since
that is a good use for my lathe and it will be a permanent solution - the
other possibility is to add a lip to the existing flat belt sheaves so that
the belt can't slip off under overload.
thoughts? remarks?
I did ask the factory in sweeden about this, they suggested replacing the
belt - do you guys believe that a belt replacement alone will fix the
problem? the old belt is thin woven fiber and it's oily so it is slippery,
but I tried removing it and cleaning the belt and the sheaves and it still
slipped off. On this machine, putting the belt on is something of an ordeal
because I have to remove a cover over the power control relays, unbolt the
relay assembly and swing it out of the way, and then reach into a hole in
the base of the mill to put the belt back on (and then reassemble
everything) - it's not like a lathe with a flat belt where you just reach
over and put it back in place
