[TowerTalk] How to apply lube to HDX589

[Bert Almemo]

Hi Bob,

With locking devices in place cables and sheaves would last much longer.

73 Bert, VE3NR 

PS. Stainless steel cables is not such a good idea according to the experts.
Galvanized is better as it's to some extent self lubricating.

Bert,

Sounds like a good option to me Bert.  I guess it is a cost issue with the
tower company.
They would need to charge more for the locking device addition and would
this addition have a positive impact on sales ?  Maybe they could offer this
an option.

The bigee for me is the cables and sheaves.  I would like to see an option
(which I would gladly pay for) to have stainless steel cables and sheaves
with zerk fittings so I could grease them regularly with my grease gun
like I do the thrust bearings on the mast.  That would be super.   I think
these options would pay for themselves,
I have hired to have the cables and bad sheaves replaced and it aint cheap
!!

73,
Bob
