My Seaview Up-Periscope build

[mickelsen]

I've got my Up-Periscope and I want to modify it to go in my Moebius Seaview. First off, the antenna fairing needs to come off of the WTC. Mike suggested the I could just slip a screwdriver blade underneath the edge of the fairing and then a quick twist would pop it off. Is that the best way to get that off, or is there a better way? I hate to risk that thin walled tubing when I don't know what I'm doing. Any help would be appreciated.

Thanks,

Grind it off -- you're concern is valid: that's Acrylic tube, easily fractured.

I think we sent you a 6" length of Lexan tube in with a recent order???

[mickelsen]

Yes, but then I realized that I would have to figure out how to get the lens off of the old tube and onto the new one. I figured that fouling up the lens was much more serious than fouling up the antenna fairing. Hence, my question.

In any event, I haven't received that shipment yet to see what would actually arrive in it, so I'm trying to cover all bases:D

OK, next question.
The special endcap that I got has a key molded into it. I think this to aid in orienting the camera each time it is installed in the Seaview. However, this key covers up part of the channel used for the O-ring to get a watertight seal. I presume that I need to grind the key back so that the O-ring channel is not blocked and then cut a notch in the edge of the WTC tube to line up with the key. The endcap also has a hole in the center. This must be to run the antenna out. It seems to me that it could also be to run a power cable in so that you wouldn't need an internal battery. This could make for a much shorter WTC and leave room in the nose of the Seaview for other things such as a (gasp!) air tank for a (GASP! choke!) reverse RCABS ballast system. (We all have evil thoughts once in a while :eek:)

What say ye?

That's no key, it's an artifact of the casting process, get rid of it. Why in the hell would you index the bulkhead to the cylinder, anyway?!

RCABS!?.... Damn you, sir!

Yes, the hole is to fit a gland through which you pass the coaxial antenna lead.

I suggest you run the two power wires to 2-56 studs set into the bulkhead -- this will insure a leak-free power make-up point.

As Skip Assay is found of saying: Keep it simple, stupid!

RCABS!...I,I don't know what came over me...maybe too much Christmas fruitcake...
