Re: [PSUBS-MAILIST] K-600 Reconditioning

[Jon Wallace <jonw@psubs.org>]

Slowly but surely...

Today I removed the fore and aft ballast tanks and it was much easier 
than I anticipated.  The forward tank was sealed at the pressure vessel 
by gobs of caulking.  Thankfully Kittredge used a silicone based caulk 
which was still pliable and I was able to break the seal pretty easily 
and remove the ballast tank.  Once the tank was off I was able to remove 
remaining caulk on both the tank head and ballast tank with a cold-chisel.

The aft ballast tank was sealed using a rubber strip about .1875 thick 
and 1.75 inches wide, nearly identical to what you would find today at 
your local hardware store for sealing air infiltration at doors and 
windows in your house.  The aft ballast tank came off very easy and 
required no cleaning because no caulking was used.

Photos for today are posted at
