[TowerTalk] Ham IV Progress

[Larry Comden]

Thanks to all who replied to my query about tackling a balky Ham IV. One question remains - see below 

0. Cleaned up the hardened grease and grime.

1. Took pictures during disassembly following K5LAD's instructions,

2. Replaced the balls,

3. Got proper grease (safe for the plastic ball retainers, -100F to 400F, etc). from a bearing distributor,

4. Found the limit switch problem: Not one of the internal wires to the limit switches was soldered!!!!!!!!!!. One can only wonder how this ever functioned from 1988 onward.

5. Reassembled and it works.

Now for a question: How much grease is enough?  Greased the tracks and lightly greased the balls. Because this was a successful project I started to work on a TR44. There was so much grease inside the TR44 it made me wonder if I'd used enough in the HamIV rebuild.

TIA & 73
