[PSUBS-MAILIST] automatic spool

Tue Oct 11 15:11:26 EDT 2016

Hi James,

I have one the same Colchester Triumph 2000 . Just for doing odd jobs as we have a CNC also.   We just fitted a good quality 3 jaw chuck Pratt Burnard and it has made a huge difference. Now we tend to use it more!  Check out the existing one for run-out.  Looks as though you got it for a good price.  Cheers Hugh.

Hi Hank

Sorry for delay, been offline for a few days.

Havent thought of an air motor, might work.  Im not very familiar with them.  But I have bought this fishing reel thing that I think will be ok.  It takes about 40 meters of line and auto winds.  plus its small.  However, im not convinced it will stand up to sea water very well.  I think its 304 stainless.  Still, i'll give it a try.

Check out this that I just bought (minus the outboard cover of course).....im super excited.  Hasnt been used for a while so needs a clean up of course, but its got loads of tooling and accessories with it.

Hi James,

Been thinking about your automatic spool for towing a surface buoy, can't remember if you mentioned an air motor.    A simple air motor   with a constant air feed could work.  The motor and spool would have to be at the surface on or under the buoy.  I am not sure how tight an air motor is, but if the motor could hold back low air pressure, it could work.  The motor would be direct drive to the spool, in fact the air motor could be the spindle for the spool.  If a constant low air pressure is fed to the motor, the line  could be pulled out against that pressure.  The pressure it build up( acting as a pump)  would vent out the regulator.  The sub could pull the line down and when the sub surfaces, the air motor would wind in the line.  I doubt a vane motor would work unless the vanes are spring loaded.  A diaphragm based motor would be ideal.
