Re: [PSUBS-MAILIST] RFC - Standard Thru-Hull Electrical Connector

[Al Secor <wreckdiver@frontiernet.net>]

I'd like to point out that this standard is really only useful for those people who do not intend to have their own dedicated comms in their sub and who wish to "borrow" one for things like the convention.  If you have your own dedicated comm system then it is a moot point and you can use any bulkhead connector or feedthru which suits your fancy.

Sean,

I don't expect home-builders to fabricate a mirror of the connector 
either, but was just observing that if we measure a unit and publish the 
physical dimensions then someone who was so inclined to do so, could 
potentially do so.  I agree that cost is likely not an issue.  Alec got 
us 20% off a single purchase which is pretty good, so I'm not sure a 
group buy is even an issue here except that we can get another 5% if 
more than 10 people commit to concept.  So far I count 4 who are likely 
to purchase.  If necessary, the membership could authorize "PSUBS" to 
purchase a couple of connectors to fill in the void and get the extra 5% 
discount, and we could then just turn around and sell those to members 
out of the PSUBS store whenever someone else needed a connector at a 
future time.  I don't think we have enough money to purchase bunches of 
them, but we could do a couple to get us over the 10 mark.

I suspect Subconn is going to want to work with us as a group anyway to 
effect the discount, otherwise they have no control over who calls and 
orders a unit under the name of "psubs".  They might as well just cut 
their retail price now 20%, or perhaps they just give anyone who asks a 
20% discount.  In any event, I would like to talk with them further to 
see what kind of a business relationship we can put together.  There are 
probably other items they have that are of interest to the group.
