To ALL,
I went all out. Build a new pole building with overhead crane. Runs the entire length of my building. The pole shed is 42 foot by 60 foot.
After reading all the e-male you guys pass back anf forth, I figured that if I am going to spend a small fortune I might as well do it
right. Also bought new equipment, lathe, vert. mill, even an old blanchard grinder. Heading out next week for a five week vacation, when we return
I will be starting the building of my submarine, IREX.

A question for those of you building in your home shops, garages or yards:
What, if any, lifting and handling equipment did you buy or build for manipulating your sub? I'm talking about A-frames, chain hoists, cranes, block & tackle, roller frames / pipe rollers, engine lifts or other contraptions to enable you to handle and manipulate the heavy pieces. For those that completed a build, what would you want to have if you had to do it again?
Sean

Hey guys,
I just want to let you guys know I received the K-350 plans yesterday!
I need to now just take some time and look through them and start writing down the modifications I want to do.

Hi Rick,
I am just finalising the design. I took a semi- finished light to a
lighting expert friend today, who is going to analyse the LED for the optimum
amperage. He says that finding the LEDs sweet spot will enable it to run cool
enough for me to go with an acrylic lens rather than glass as I had intended.
Will keep you in the loop with regard to progress, but shouldn't be too far off.

Hey Alan,
Thanks for the input! Do you have any construction pictures of the lights and housings or just a finished picture?

Rick,
the lights I am making are 80mm diameter x 70mm long.
There is a 100mm flange for mounting that also holds the lens in.
So it will fit in to a 80mm diameter hole & bolt or screw to surrounding material.
The LEDs are 80W at 105 lm/W, so 8,400 lm. However I may not drive them that
hard, depending on how hot they get in water.
I am building a 1 person sub similar to Cliff's R300 & will be having
two arranged like car head lights + 1 either side, 1 looking backward
& 1 slightly longer as a spot light.
I may use the same design as navigation lights, with colored lenses & just back
off the power to them.
Cheers Alan

Hey Cliff
That's quite a makeover! I agree, when I bought my plans, it seemed I was having to call Ketteredge a lot for clarification and would of welcomed a cleaned up set.
On another note, I am getting ready to fabricate all my external light housings and would like to hear from anyone who is using LED lighting in their housings as far as how many lumans they are and what diameter they are etc.
Thanks
Rick

Spent a couple of months last year working on the design of a modified K-350. I found he original K-350 plans to be pretty weak. Changes made were:
Removed aft external motor and prop and replacedwith two fixed Minn Kota 101 thruster with kort nozzle like I have on the R300
Replaced vertical thrusters with two fixed MinnKota 101 thrusters with kort nozzle
Propulsion and depth station keeping all fly by wirewith joystick control
Move air tanks (two 100 SCF aluminum scuba tanks) outside hull old location of mainpropulsion motor
PLC for control of all systems (same as R300)
HMI and joystick on mobile to permit operationfrom prone, sitting or standing position.
Replaced life support with fully automated designused on R300
Moved electrical components into threeelectrical boxes on or near aft elliptical head
Added sensors for main and auxiliary batteryvoltage and current, ambient water pressure and temperature, cabin pressure,temperature, and humidly, compass heading, boat roll and pitch, boat altitudeand speed. Life support system hassensors for CO2, O2 concentrations, O2 tank pressure, mass rate of O2 during O2makeup. Pressure sensor for HP air bank and regulated air pressure.
Increased main battery capacity to 400 Ah which required increasing the battery poddiameter to 16? OD and 47? seam to seam
Replaced the main and auxiliary battery banks with 16 OPTIMA BATTERIESBLUE TOP DEEP CYCLE MARINE BATTERY GROUP D34M. 12 for main buss and 4 for auxiliary buss. 8 batteries per pod
Widened the spacing on battery pods to 38?
Added two additional viewports
Added external LED lights
Added compass/pitch/roll sensors off R300
Changed design of battery pods detachable heads toflange style
Redesigned the MBT and VBT controls.
Utilize Hugh Fulton pancake style pneumaticallyoperated MBT vent valves
Modified MBTs by closing the bottoms
lengthened VBT to 18? seam to seam to increasethe volume to 8.75 gals
Added compass/pitch/roll sensors off R300
Built out boat in Autodesk Inventorprofessional.
Drawing package updated, 51 assembly drawingsand 160 part drawings
With mods, the current boat weight is 4,707 lbs,without pilot or passenger
With mods, the current boat submergeddisplacement is 4,866 lbs,
Buoyancy of boat with VBT and MBT fully blown is5,849 lbf
Boat Reserve of buoyancy is 9.2%

Emile,
I actually already started a list on what I want to improve on the K350!
I was actually thinking about having a 1 meter hull dia
Improve depth rating to around 300 meters
Look into improving the ballast tanks
Have the thrusters be controlled by a joystick

Ludwig,
The K350 is a nice sub and the plans might be a good start .
Mind some points are a bit outdated.
If I build a K350:
-1 meter hull dia (was 900mm)
-improved ballast tanks
-dome window in the bow

Hey guys,
Who should I contact regarding the purchasing of the K-350 plans?
I bought the plans at the end of December and still haven't received them. I also sent an email off to sales at psubs.org around two weeks ago and haven't gotten a reply.
Thanks,
Ludwig
