Holding tank access panel

[dar636]

Speaking of holding tanks, the top access plate on mine has started to corrode. I discovered the grounding strap had a break in it and so started the problem. I’ll pull the screws out one at a time, probably have to drill them out. They look like 1/4-24 Bronze My question is what do the screws go in to? Individual nut plates or inserts, or is there a retaining ring that can fall into the tank if all screws are pulled?Does anyone know if Sams would have a tank access plate or should I plan on making one?

They are threaded into the glass. The tank is plenty thick there. I have a video of it if you like me to post the link.

That plate is very very thick. I’d be surprised if you can’t clean it up and re-install it.

OK. I’ll post the results if I can clean it up.

If you can find that video, I'd appreciate seeing it. Looks like I may have to tackle the same problem pretty soon on my top holding tank plate as well.

Thanks

Success!! I got lucky:

1. As noted by raclarkson the tank has captive nuts for the access panel
2. Mine hadn't started leaking
3. Pretty accessible all in all
4. Thick material

I went slow and didn't make it worse which can be a tendency of mine... I had to drill out and tap each hole to the original 1/4-20 but since each brass screw had turned to dust I didn't have to go oversize. The brass screws ended up being the anode once the bonding failed.

I have the bonding drawing for this boat and will rework the forward end this weekend along with re-installing the Gobius quantity system. Enjoy the pics.

Are those hose legends in indelible ink? First class job.

Nice job on the holding tank repair. Have something similar in my future. It was my understanding, Hatteras changed the waste extraction pipe in the holding tank to a non-metallic material (as the original ones corroded apart). My question, if this is true what year did the change take place?

Trying to set my expectations of what I am getting myself into.... Thanks!
