 Thanks James,She's looking great.I would be a bit nervous about the access panel leaking if you ever left her sitting inwater for a long time. I presume it is the same type I have & screws in.Alan

Hi All
I meant to reply re a couple of enquiries on my new sub.  I havent really done much other than build the battery pods and they are not yet fitted.  But i am going to crack on this winter.  I have been doing a load of other non-Sub related projects.
It will get done.  Eventually.  :)
Hoping to get another dive in Jodie B in the next week or so.  Weather permitting.  My diving support is back from holiday now, so i wont be on my own.

The cool thing is they are height-adjustable. Originally my trailer was as low as James', but I actually raised it a bit because of hitting rocks on crummy ramps, of speed bumps.

Hi James, It looks great. I agree with Alec on the torsion axles. Thats the direction I am going on my trailer mods.
Best Regards,

Hi All,Some pics of the modifications I have made to Jodie B over the winter.
Aft tank access panel so I can easily get to the motor compensation tubes.  I have put 2x long tubes on with a ball valve on the end of each one.  I can now easily fill the motor from above throught the access port and just close the valves.  The long tubes dangle down low and act as the bladders.  I was particularly pleased with the gelcoat work as i had never done this before, and I had to make a flat point out of glass fibre to mount the hatch to and then gelcoat it to blend it into the main tank.

Access panel for the O2 tank.  No more scrambling around trying to lift if onto the bracket.

Made a glass fibre tube to mount the O2 tank in.  I can now just slide it in and out of the side panel hatch into the tube.  Was getting carried away with GRP work.  My first proper moulded thing.<20190722_151919.jpg>

New compensation system.  i took the risk and welded the 90 degree pipe nipple to the top motor casing and welded the bottom one shut.  Ground the connection flush on the inside.  Now there is nowhere for air to trap.  I can fill the motor through the top tube and close the valve.  The valve just connects to a bracket underneath to keep it out the way.  No more air bubbles in the motors.<20190722_152033.jpg>

Re-mounted the dome on a 1mm cork\neoprene gasket instead of the EPDM one after Hank did some experiments and found the EPDM to extrude quite a lot.<20190722_152045.jpg>
I also made a new super low loading trailer for taking up less room in the workshop.  I was hoping to be able to launch off it, but its not really road legal so i have only used it in the shop so far.  Note there are no proper axles so the bed is lower than the centre wheel hight.
