[TowerTalk] How to apply lube to HDX589

[Bob K6UJ]

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
