Bob,
I was wondering what happened to you.  I can most certainly make a trip down to give a hand if your stuck. I can take my bride down for some shopping :-)  
Email me at hankpronk at live.ca  and we can set it up for next weekend. I have been wanting to see what you doing.

 Alan,
 
  
 Thank you for your reply.  My name is Bob Travis.  I
 don't know how to make my name show up on my emails like
 the rest of the group and I apologize for not signing my
 question.  I have watched the threads for years now and I
 met some of you at the Psubs convention in Washington this
 last year (I was the one that no one was expecting).  But
 for the most part, I have just watched,
 read and attempted to learn.  
  
 A little background...  I started dreaming about a sub
 in 2005.  My wife (aka.. the read head) gave me permission
 to proceed, but of course, has occasionally put up some road
 blocks which has delayed things a bit.  I started the
 actual construction a little over 5 years ago.  I have
 studied Trustworthy, Persistence and Guernsey Submarine as
 well as snoopy and some of the other boats on the
 site and have gained great a great bit of knowledge and
 direction.  I have also learned an amazing amount from
 reading the threads from the group.  
  
 About me...  I am the quiet one that sits in the
 back of the class not wanting any attention. I have a huge
 problem with putting myself out there.  I live in Eastern
 Washington and I am building a K-350...... and, because of
 the above, have not posted my project pictures on the
 site.  I keep thinking that I am going to do this but I
 just haven't taken the time (or built up the nerve).  I
 am a pencil pusher.  I don't have a mechanical bone in
 my body!  So some of the most basic things are very
 difficult for me to get my arms around.  Want to negotiate
 a $500,000 deal, I'm your guy!  Want to hook up an
 electrical panel... Ahhhhhhh????????    I have made
 almost all of my structural parts, have had them welded and
 am now working on my electrical and have not a clue what I
 am doing at this point.  I am struggling with some of the
 most basic items (like finding the correct ampere meter) and
 for some reason have a mental block on how to proceed.  I
 really appreciate your response and will follow the
 link!
  
 I am at the point where the red head has told me to
 "get that stupid thing done" and I am not going to
 question it!  With her recent permission, I have a renewed
 energy level and will be doing what ever possible so that I
 am testing in August!  So with that said, I am going to be
 asking a bunch of very basic, stupid questions!  I will do
 my best to go back through the archives as to not bog the
 group down with previous topics.
  
 Hank... Any chance you will be making a journey to
 Spokane any time soon???
  
 Thanks again everybody!!!  And with your help, and a
 little luck, I will be dragging my boat to the next Psubs
 convention on the east coats so you all can teach me how to
 dive it!
  
 Bob

 Hi,
 not sure
 who I am talking to, but the brushless motors put out a lot
 less
 electronic
 noise, so less interferance with sensitive
 equipment.
 They
 don't wear out as quickly, as they don't have
 brushes, & you get more power 
 for the
 same size unit. About 7 out of 8 thruster manufacturers use
 BLDC motors.
 There are
 a host of cheap motors at "Hobby King" With 785
 Watt motors for $25-
 http://www.hobbyking.com/hobbyking/store/__522__517__Electric_Motors-45_to_50mm.html
 You need
 an esc (electronic speed controller ) which costs about
 $50-.
 The escs
 normally work off a receiver sending them commands from the
 remote control transmitter.
 However
 there are control units you can buy that are wired straight
 to the esc.
 I  am
 experimenting with BLDC motors at the moment & are
 wanting to make up a thruster.

 Is there a reason I should go with a brushless
 motor?  I can get a 500 watt, 36 volt scooter motor for
 about 50 bucks but brushless are harder to find and more
 expensive.  Is there an email thread on this already?  Has
 this been a topic of discussion in the
 past?
