[PSUBS-MAILIST] Fw: mould

[hank pronk via Personal_Submersibles]

Alan, The centre hole is quite large so it will be easy to reach, the actual fibreglass  portion is only 19 inches from the edge to the centre opening.  Good idea, I am sure I will need a sail of some sort, I was thinking a 1\4 inch thick acrylic oval thing.I am planning electric valves for venting, I had 100% success with them on my log salvage ROV and we did a kazillion cycles and the only trouble we had was they would freeze at the surface before the sink cycle.  Easy solution, it was to damn cold to be on the water anyways. :-)Hank

 Thanks Hank,have fun. You might need to build a scaffold over that to get tothe center. The thought came to mind that you could embed bolts on the back side of it, around the hatch area, & thenbolt on a self draining conning tower for when it is needed.Alan

Alan,Yes the centre will be cut out and 3 inches of the sphere will protrude.  It is not clear in the picture, but the entire top is sloped 1.5 inches over 19 inches, to allow for venting.Hank

 Hank,I'm not sure what you are doing here.There is a circle drawn in the middle, is this cut out & will the MBT be fitted around the hatch. As it is the top I am surprized it is flat as the air won't rise to a central point to be exhausted.Alan

This is one half of the mould for the MBT slash trawl float house on Elementary 3000  After this part is glassed up, then the bottom portion will be formed and the two halves will be married together.  There will be a second set of moulds to encase the HP and O2 tanks.  This whole process will take me all next week to complete.  Hank
