hi john,
what material are you using for gasket,i am using silicone gel sheet 2mm thick. I have had to remove top a couple of times and the gel sheet seems to stretch. this has resulted in a leak or two.

sub john · « **Reply #117 on:** July 30, 2016, 09:58:57 pm »

HI Alan
I use silicone bath sealent to make the gaskets, what i do first is the poly carb sheet has had all the holes drilled to match the holes on the pressure plate top so they all line up with the bolts that are bonded in from underneath once i know all this is lined up then i spray PVA mould release agent on the under side of the poly carb sheet i then apply about 1/2 inch thick silicone bath sealent around the screws on the top of the pressure plate forming like a cone shape all the way down the center line of the screws i now place the poly card sheet down on to it and to make it so that the poly card sheet can not compress to much of the silicone out i place on the edge of the poly card sheet about every 5 inches apart M4 nuts to use them as spacers and then i put some M4 nuts on the bolts to keep the poly carb sheet down to stop the gasket miss shaping leave it for about 4-5 days while the silicone is going off the beauty about using the PVA is when you won't to pull the poly carb sheet off the new formed gasket just put it in the bath let it soak in water and the PVA will just dissolve leaving a dead smooth gasket. But what i should have said is you can go around the edges and cut any excess of silicone gasket away before you put it in the bath.

Trouble is if you are trying to put a gel gasket on to the pressure plate top that is 2mm thick you have got to bond it down to stop it from moving around, what i would do is to put a bead of silicone on to the pressure plate top then put the gel gasket down on to it then put the poly carb sheet down on to the gel gasket and put some nuts or bolts which ever you are using to squeeze out any excess silicone from under the silicone gel sheet. But to be honest i always make my own then i can make them as thick as i won't them.

Trouble is with alot of silicone bath sealent the fumes that come off it will attack electronic components until it has gone off so i always try to do this before i put any thing in the sub
Hope it helps All the best John

see your point about the gasket on the move.just done the fore and aft covers gasket plus bond with sealer result ok.making a new top for main cover just found a hairline crack from one of the holes uphill aint the word.
many thanks for info.

hi john.
going ok now a little more ballast in hull,new top made,due to space left I have 3 7.2v 4600mah packs in the boat,any ideas what kind of charger for these 3 in parallel not to concerned how long the charge takes.
alan b

sub john · « **Reply #120 on:** August 01, 2016, 10:11:58 pm »

HI Alan
One of the chargers i use is a few years old now but the charging software is very good plus you can charge your main battries in your sub and charge your transmitter at the same time, it is a graupner ultra duo plus 30 and I'm sure you can still get it. I brought a IMAZ B80 charger/discharger that works quite well but i did a bit of reworking on the balancing for the Lipos trouble is today it is not worth trying to make chargers because there is so many out there which is so cheap, but then again you only get what you pay for.

Glad to see you are making progress on building your Engel Gato it is alot of work which you are finding out, but i can say i would not like to make mine again the thing that slows me down is having to design the electronics.

All the best John

abreese · « **Reply #121 on:** August 02, 2016, 04:59:02 pm »

hi john.
am I right to assume you can parallel charge with this type of charger on nimh batts.
alan

sub john · « **Reply #122 on:** August 03, 2016, 07:27:33 pm »

HI Alan
The first thing i would do if you was putting 3 packs together in parallel i would charge each pack on it's own till it is fully charged then put the 3 packs together and leave them connected together that way you can discharge and charge them all together. I have got 4 packs connected in my Engel Gato and it works fine, and with that Graupner charger you can parallel charge them and just alter the time that the charger will stay on for charging and you can alter the charge current
Hope it helps John

John,
What amp do you charge your NiMh? do you use 1 amp, 0.7 amp, or what?
